 title: Color Grading
-description: "Apply real-time color grading, presets, LUTs, finishing, and media effects to video and image media in Studio and final renders."
+description: "Correct and creatively grade video or image media with presets, scopes, color wheels, curves, HSL selections, and custom LUTs."
 ---
 
-HyperFrames Studio can color grade project-local `<video>` and `<img>` media directly in the preview. The same `data-color-grading` settings are used by the render pipeline, so the exported video should match the look you preview.
+HyperFrames provides real-time, media-level color grading for project-local
+`<video>` and `<img>` elements.
 
-This is a lightweight media color tool for generated videos, uploaded footage, social variants, and agent-authored compositions. It is not a DaVinci Resolve, Premiere, ACES, or OCIO finishing pipeline.
+Studio and AI agents use the same validated grading contract, and final
+rendering runs the same shader pipeline used by the preview.
 
-## What Is New
+The current pipeline is designed for SDR/Rec.709-oriented work. It provides
+professional primary and selective grading tools, but it is not an ACES, OCIO,
+or native HDR finishing pipeline.
 
-| Capability | Status | Notes |
+## The Mental Model
+
+| Stage | Purpose | HyperFrames tools |
 | --- | --- | --- |
-| Studio Color Grading panel | Supported | Appears on selected `<video>` and `<img>` elements. |
-| Manual controls | Supported | Exposure, contrast, highlights, shadows, white point, black point, warmth, tint, vibrance, saturation. |
-| Presets | Supported | Named HyperFrames presets backed by shader settings, not bundled third-party LUT packs. |
-| Custom LUT upload | Supported | Project-local 3D `.cube` LUT files with strength control. |
-| Finish | Supported | Vignette and grain, with advanced settings behind the settings icon. |
-| Studio Effects panel | Supported | Essentials, Retro & Glitch, Print, and Art effects share the same media shader and persisted `effects` object. |
-| Studio Overlays panel | Supported | Inserts selected Registry overlays at the media timing as ordinary timeline layers. |
-| Before preview | Supported | Hold the compare button to temporarily show the ungraded media. |
-| Render parity | Supported | The render pipeline redraws the color-grading shader after video-frame injection. |
+| Correct | Fix exposure, contrast, tonal balance, and casts | Adjust controls and source analysis |
+| Grade | Shape color and mood | Tonal wheels, RGB curves, hue curves, and HSL color selections |
+| Apply a look | Start from a tested style or an existing external look | Presets and custom 3D `.cube` LUTs |
+| Finish | Add restrained optical texture | Vignette and grain |
+| Stylize | Transform the pixels beyond normal grading | [Media Effects](/guides/media-effects) |
+| Dress | Add an authored HUD, flash, light leak, or freeze-frame layer | [Media Overlays](/guides/media-overlays) |
 
-Studio labels `whites`, `blacks`, and `temperature` as White Point, Black Point, and Warmth. Use the JSON keys shown in the data shape when authoring `data-color-grading` by hand or through an agent.
-
-## Support Matrix
-
-| Source / workflow | Supported? | What to expect |
-| --- | --- | --- |
-| 1080p SDR video | Yes | Best default path. Good for most uploaded/generated MP4/WebM/MOV media that browsers can decode. |
-| 4K SDR video | Yes | Works when the browser and machine can decode it. Preview/render cost is higher. A 4K source only produces 4K output when the composition/render is also 4K. |
-| 1080p / 4K images | Yes | Works on normal project-local images. Output resolution follows the element/composition render size, not hidden extra detail beyond that size. |
-| iPhone SDR video | Yes | Treat as normal SDR media when it is tagged/decoded as SDR. |
-| iPhone HDR / HLG / Dolby Vision-style uploads | Partial | The media can be loaded if browser/FFmpeg support the file, and Studio warns when HDR metadata is detected. The live Color Grading shader is still an SDR preview path, not true HDR grading. Use the existing [HDR Rendering](/guides/hdr) pipeline for HDR delivery and verify the output. |
-| HDR render output | Related, not new | HyperFrames already has HDR render support. Color Grading does not yet provide HDR-aware grading controls. |
-| LOG camera footage | Partial | Sliders and LUTs can be applied, but HyperFrames does not auto-detect camera LOG profiles or apply ACES/OCIO input transforms. Use a matching conversion/look LUT if you know the source profile. |
-| Rec.709 creative LUTs | Yes | Best LUT path today. Use project-local 3D `.cube` files. |
-| Camera conversion LUTs | Partial | Technically accepted if they are supported 3D `.cube` files, but correctness depends on the source footage matching the LUT's expected input color space. |
-| Full-scene grading including text/DOM | Not yet | Color Grading is media-only. Captions, text, SVG, and regular DOM overlays stay unchanged. |
-| Face/region-only grading or privacy | Not yet | Realtime effects process the whole selected `<img>` or `<video>`. Isolate the region into a separate cropped/masked media layer or use an external segmentation/tracking tool first. |
-| Remote media URLs | Partial | WebGL pixel processing requires compatible CORS headers. Project-local assets are the reliable path. |
-| Professional ACES/OCIO/HDR finishing | Not yet | Future render/color-management work, not this Studio shader path. |
-
-## How It Works
-
-Color grading is stored on media elements as `data-color-grading`:
-
-```html index.html
-<video
-  id="hero-video"

-
-The runtime creates a sibling WebGL canvas for the media element, samples the current video or image frame, applies shader uniforms, then hides the native media only after a shader frame is ready.
+All pixel-level stages are stored together on the selected media element. An
+overlay is different: it is an ordinary editable composition layer above the
+media.
 
 ## Studio Workflow
 
-Select a real `<img>` or `<video>` element in Studio to open the media tools:
+Select a real `<img>` or `<video>` element to open Color Grading in the Design
+panel.
 
-1. **Presets** shows every built-in starting point in a responsive preview
-   grid. Hover to preview it on the selected media, click to apply it, or choose
-   **Original** to return to the neutral preset.
-2. **Adjust** provides tonal and color correction.
-3. **Effects** groups configurable shader controls under Essentials, Retro &
-   Glitch, Print, and Art.
-4. **Finish** provides vignette and grain.
-5. **Custom LUT** accepts a project-local 3D `.cube` file.
-6. **Overlays** installs Camcorder HUD, Editorial Flash, Organic Light Leak,
-   or Freeze-Frame Cutout from the existing Registry.
+<Steps>
+  <Step title="Inspect the source">
+    Open **Scopes** and choose Histogram, Waveform, RGB Parade, or Vectorscope.
+    Scopes refresh from the selected media frame and help identify clipped
+    highlights, crushed shadows, channel imbalance, and saturation before you
+    make creative changes.
+  </Step>
+  <Step title="Make the primary correction">
+    Use Exposure, Contrast, Highlights, Shadows, White Point, Black Point,
+    Warmth, Tint, Vibrance, and Saturation. Correct obvious source problems
+    before applying a stronger look.
+  </Step>
+  <Step title="Shape tonal color">
+    Use the Shadows, Midtones, and Highlights wheels. Each wheel provides hue,
+    color amount, and level, so color and brightness can be adjusted within the
+    same tonal zone.
+  </Step>
+  <Step title="Refine with curves">
+    Use the Master curve for overall luminance, Red/Green/Blue curves for
+    channel shaping, and Hue vs Hue, Hue vs Saturation, or Hue vs Luma for
+    hue-selective adjustments.
+  </Step>
+  <Step title="Isolate a color when needed">
+    Add a Color Selection, capture the current frame, and use the eyedropper to
+    initialize its HSL qualifier. Switch to **Selection matte** to inspect the
+    selected pixels, refine hue/saturation/luma range and softness, then apply
+    bounded hue, saturation, luma, temperature, or tint correction. Up to four
+    ordered selections are supported.
+  </Step>
+  <Step title="Choose a look and finish">
+    Preview a built-in preset on the selected media or load a project-local 3D
+    `.cube` LUT. Use vignette and grain only when they support the visual
+    direction.
+  </Step>
+  <Step title="Compare and render">
+    Hold the compare control to see the ungraded source. Scrub representative
+    frames, verify faces and highlights, then render. The final render redraws
+    the grading shader after exact video-frame injection.
+  </Step>
+</Steps>
 
-An overlay inserted from this panel starts with the selected media, uses its
-duration, and is placed on the next visual track when one is known. It then
-behaves like any other composition layer: edit or remove it through Layers and
-Timeline. The left Catalog remains the browse-all Registry surface.
+To reuse the complete authored grade, use **Copy grade to** and choose
+**Current file media** or **All project media**, then click **Apply**. This
+copies the validated payload to other real media elements; it does not alter
+overlay, caption, or DOM layers.
 
 <Note>
-Color Grading is intentionally **media-only**. It applies to `<video>` and `<img>` sources. Captions, text, divs, SVG, and UI graphics remain ungraded unless you render them into media first.
+  Color Grading is media-only. It processes real `<video>` and `<img>` elements,
+  not captions, text, SVG, or arbitrary DOM. Use first-class media elements for
+  visual assets that should remain editable and gradeable.
 </Note>
 
-<Note>
-Project-local media is the safest path. Remote media must be served with compatible CORS headers and should use `crossorigin="anonymous"` when pixel processing is needed.

+The three wheels target broad tonal zones:
 
-Omit `enabled`; the presence of `data-color-grading` implies that grading is active. All numeric controls are clamped by the runtime. The current color grading path is Rec.709/sRGB-oriented and assumes browser-decoded media frames.
+- **Shadows** shapes dark regions.
+- **Midtones** shapes most faces, products, and general scene color.
+- **Highlights** shapes bright regions and specular areas.
 
-`chromaBleed` is a bounded `0` to `1` treatment primitive that horizontally
-softens chroma detail while preserving the center sample's luma. It is useful
-inside restrained creator-camera/camcorder treatments; it is not VHS, CRT, RGB
-split, tracking noise, or a complete camera emulation.
+Use small amounts first. The **Level** control changes the brightness of the
+same tonal zone, while hue and amount introduce color.
 
-Most effect amounts and settings are normalized from `0` to `1`. Bloom supports
-up to `3`, bloom radius uses pixels, and enum controls use the integer choices
-shown in Studio:
+### RGB Curves
 
-- `tapeDamage` adds deterministic horizontal time-base instability, lower luma
-  bandwidth, restrained ghosting, noise, sparse dropouts, and bottom-edge head
-  switching. `tapeTracking` adds bounded moving horizontal tracking tears,
-  `tapeNoise` scales tape noise and row jitter, and `tapeSpeed` controls their
-  deterministic motion (`0.5` is normal speed). These three subordinate
-  controls do nothing without `tapeDamage`. A complete analog-tape treatment
-  may also use restrained `chromaBleed`, scanlines, RGB separation, and rare
-  row tears; none of these controls adds CRT curvature.
-- `filmArtifacts` adds deterministic sparse dust and short scratches. Combine
-  it with existing grain, vignette, color, and seek-safe GSAP gate weave for an
-  8mm treatment. It does not change the frame by itself when set to `0`.
-- `halftone` blends in a four-angle CMYK print screen. `halftoneSize` controls
-  its resolution-aware dot-cell size from fine to coarse. The channel angles
-  and edge response use fixed print-oriented defaults to keep authored output
-  consistent across agents.
-- `twoInkPrint` maps warm midtones and deep/cool shadows to fixed original
-  vermilion and teal spot screens with a dark overprint on warm paper.
-  `twoInkPrintSize` controls its resolution-aware screen size. Do not combine
-  it with `halftone` or describe it as a named commercial print process.
-- `ascii` converts the selected media to a procedural 5x7 glyph field.
-  `asciiSize` controls cell size and `asciiInvert` switches the light/dark ink
-  polarity. It uses the first and last colors from `palette`.
-- `dither` applies a temporally stable ordered 4x4 Bayer dither.
-  `ditherSize` controls cell size and all `palette` colors participate in the
-  result. This is ordered dithering, not Floyd-Steinberg or another sequential
-  error-diffusion algorithm.
-- `bloom` extracts bright pixels and runs a bounded half-resolution separable
-  blur. `bloomRadius` controls its radius.
-- `monoScreen` provides configurable mono print shapes, angle, spread, invert,
-  and palette controls.
-- `scanlines`, `crtCurvature`, and `chromaticAberration` provide display
-  geometry and channel treatments with their related settings.
-- `digitalGlitch` provides deterministic line tears, blocks, displacement,
-  selective pixelation, channel split, opacity, and speed controls.
-- `engraving`, `crosshatch`, and `kuwahara` provide stylized art treatments with
-  their calibrated settings. Kuwahara uses bounded half-float intermediate
-  targets when the browser supports them and otherwise reports unavailable.
+- **Master** remaps overall luminance.
+- **Red**, **Green**, and **Blue** remap individual channels.
 
-`palette` accepts two to six exact `#RRGGBB` colors in authored order. Use
-dark-to-light order for normal luminance mapping; intentionally reverse the
-array for an inverted result. The runtime validates and lowercases colors but
-does not reorder them. ASCII, dither, mono screen, engraving, and crosshatch use
-it; a palette or subordinate setting alone does not allocate an effect. Omit it
-for the family default.
+Curve points are normalized `[input, output]` pairs. Endpoints are implicit,
+and each curve supports up to 16 points. An S-curve increases contrast; lifting
+the lower-left region raises shadows; channel curves can build split-tone or
+cast-removal adjustments.
 
-When effects are combined, HyperFrames evaluates them in one fixed,
-deterministic order: source framing and multipass blur/Kuwahara preparation;
-chromatic and digital glitch; primary color grading and LUT blended by global
-intensity; grain and film
-artifacts; mono/engraving/crosshatch/halftone/two-ink/dither/ASCII; bloom,
-scanlines, vignette, and CRT display masking; then before/after comparison.
-Effects cannot currently be reordered. The fixed
-pipeline keeps Studio, playback, seeking, and final render behavior
-predictable.
+### Hue Curves
 
-Studio exposes these controls in the selected media element's **Effects**
-accordion. Agents should choose one primary intent through the `media-use`
-skill, then either seed from a source-aware treatment recipe or inspect the
-canonical toolbox and assemble a bespoke combination:
+- **Hue vs Hue** moves a selected hue toward another hue.
+- **Hue vs Saturation** changes saturation around a selected hue.
+- **Hue vs Luma** changes brightness around a selected hue.
 
-```bash
-hyperframes media-treatment --capabilities --json
-hyperframes media-treatment --capability kuwahara --json
-```
+Hue curve points are `[hueDegrees, delta]` pairs and wrap around the color
+wheel.
 
-The first command reports a concise overview of every capability family. The
-focused query reports one family's or effect's controls, calibrated apply
-payload, render lane, palette support, and seek-safe animation paths. Use
-`--all` only for exhaustive tooling. Recipes are tested shortcuts, not the
-complete allowed surface. Persist the final combined payload with the same
-`hyperframes media-treatment` command; unknown keys are rejected before the
-composition is changed.
+### HSL Color Selections
 
-## Custom LUTs
+A color selection qualifies pixels by hue, saturation, and luma, then applies a
+correction only inside that matte. This is useful for restrained tasks such as
+reducing an overly saturated shirt, cooling a background color, or protecting
+skin from a broad creative grade.
 
-HyperFrames supports project-local 3D `.cube` LUT files:
+HyperFrames supports up to four ordered selections. These are static
+media-level qualifiers: they do not include object tracking, rotoscoping,
+facial recognition, or spatial masks.
 
-```html index.html
-<img
-  src="assets/product.jpg"
-  data-color-grading='{
-    "lut":{"src":"assets/luts/product-pop.cube","intensity":0.7}
-  }'
-/>
-```
+### Scopes
 
-Use `.cube` LUTs when users already have a look from another editor or camera workflow.
-
-- HyperFrames currently supports 3D `.cube` LUTs for this path.
-- 3D cube LUTs up to `LUT_3D_SIZE 64` are supported.
-- 1D `.cube` LUTs and mixed 1D+3D LUT files are not supported yet.
-- Supported headers include common `DOMAIN_MIN` / `DOMAIN_MAX` and DaVinci/IRIDAS-style `LUT_3D_INPUT_RANGE`.
-- LUTs are not universal. A LUT looks correct only when the source footage roughly matches the LUT's expected input color space.
-- Rec.709 creative LUTs are the safest fit today.
-- LOG/camera conversion LUTs can be used, but HyperFrames does not yet manage camera color profiles for you.
-
-## Render Behavior
-
-Color Grading is part of the media runtime, so render uses the same settings as Studio preview. During render, HyperFrames injects exact video frames and asks the color-grading runtime to redraw before capture.
-
-For 4K output, use the existing [4K Rendering](/guides/4k-rendering) workflow. Color Grading can run at 4K when the composition/render surface is 4K, but a 1080p source video does not become sharper just because the final render is 4K.
-
-Performance follows the total number of treated pixels and the selected render
-lane, not only the number of media elements. Several tiled videos can be
-cheaper than several overlapping full-frame videos. Blur, Bloom, and Kuwahara
-use multipass rendering. When more than two full-frame multipass-treated media
-elements are visible together, verify continuous playback on the target
-machine and simplify or pre-render the stack if frames drop. HyperFrames does
-not impose a universal hard cap because GPU and decoder capacity varies by
-device.
-
-For HDR output, use the existing [HDR Rendering](/guides/hdr) workflow. Color Grading currently warns on detected HDR media, but the grading controls themselves are not HDR-aware.
-
-When grading a video, animate opacity on a wrapper element instead of directly on the `<video>` element. The runtime hides the native media and draws the graded result through a sibling canvas, so wrapper opacity preserves preview/render parity.
-

-## Agent-Friendly Examples
+Studio scopes analyze a captured selected-media frame. They are inspection
+tools and do not change the grade.
 
-For AI agents, keep the instruction declarative:
+## Built-In Looks
 
-```text
-Apply a clean studio preset to assets/interview.mp4, reduce highlights slightly,
-lift shadows, add subtle vignette, and keep captions ungraded.
-```
+HyperFrames ships tested shader-setting presets, not bundled LUT files:
 
-Expected markup:
+| Intent | Presets |
+| --- | --- |
+| Natural and corrective | Neutral, Warm Daylight, Clean Studio, Skin Soft, Food Pop, Night Lift |
+| Editorial and tonal | Muted Editorial, Vintage Wash, Soft Boost, Bright Pop, Deep Contrast |
+| Monochrome | Mono Clean, Mono Fade |
+
+Use these as starting points and tune them for the actual source. Presets that
+also activate a stylized shader treatment are documented under
+[Media Effects](/guides/media-effects).
+
+## Agent Workflow
+
+Agents should use the CLI as the normal authoring surface. The
+`data-color-grading` attribute is the persistence contract, not the first thing
+an agent needs to memorize.
+
+Users do not need to name a technical control. Requests such as _"this
+interview feels too dark and cold"_ or _"polish the footage without making it
+look filtered"_ route through the `media-use` skill, which inspects the source,
+discovers the relevant contract, applies a deterministic payload, and verifies
+the result.
+
+<Steps>
+  <Step title="Discover the relevant surface">
+    ```bash Terminal
+    hyperframes media-treatment --capabilities --json
+    hyperframes media-treatment --capability grading --json
+    ```
+
+    The overview stays concise. Focused queries such as `wheels`, `curves`,
+    `hue-curves`, `secondary`, `scopes`, or `lut` return exact controls, bounds,
+    and examples.
+  </Step>
+  <Step title="Analyze the selected source">
+    ```bash Terminal
+    hyperframes media-treatment \
+      --project . \
+      --file compositions/interview.html \
+      --selector '#interview' \
+      --analyze \
+      --json
+    ```
+
+    Analysis measures a local media source and returns metadata, warnings,
+    diagnosis, and a bounded suggested primary-correction patch. It does not
+    replace visual judgment or automatically invent a creative grade.
+  </Step>
+  <Step title="Apply a validated grade">
+    ```bash Terminal
+    hyperframes media-treatment \
+      --project . \
+      --file compositions/interview.html \
+      --selector '#interview' \
+      --grading '{"adjust":{"highlights":-0.08,"shadows":0.06},"wheels":{"midtones":{"hue":32,"amount":0.05}}}' \
+      --apply \
+      --json
+    ```
+
+    Use `--dry-run` when target or scope is uncertain. Use `--clear` to remove
+    the complete treatment from the target.
+  </Step>
+  <Step title="Verify representative frames">
+    Inspect more than one frame for video, compare before and after, and render
+    a short draft when the grade is important to the final result.
+  </Step>
+</Steps>
+
+Agents should normally start from source analysis or a tested preset, then add
+small, explainable adjustments. Directly inventing many unrelated curve and
+secondary values is difficult to review and easy to overcook.

+The contract rejects unknown keys and clamps numeric values to Core-owned
+bounds. Query the current contract instead of copying bounds into agent
+instructions:
+
+```bash Terminal
+hyperframes media-treatment --capability secondary --json
+hyperframes media-treatment --all --json
+```
+
+Use `--all` only for exhaustive tooling or contract inspection.
+
+## Custom LUTs
+
+HyperFrames supports project-local 3D `.cube` LUTs:
+
+```json
+{
+  "lut": {
+    "src": "assets/luts/product-look.cube",
+    "intensity": 0.7
+  }
+}
+```
+
+- 3D `.cube` LUTs up to `LUT_3D_SIZE 64` are supported.
+- 1D and mixed 1D+3D `.cube` files are not supported.
+- Common `DOMAIN_MIN`, `DOMAIN_MAX`, and DaVinci/IRIDAS-style
+  `LUT_3D_INPUT_RANGE` headers are supported.
+- HyperFrames does not bundle third-party LUT packs.
+- A LUT is only correct when its expected input color space matches the source.
+- Rec.709 creative LUTs are the safest current workflow.
+- Camera LOG conversion LUTs can be loaded, but HyperFrames does not identify
+  camera profiles or apply ACES/OCIO input transforms automatically.
+
+Never paste a `.cube` body into an agent prompt. LUT files commonly contain
+tens of thousands of numeric rows. Keep the file local and use metadata,
+validation, and rendered comparisons to evaluate it.
+
+## Support Matrix
+
+| Source or workflow | Status | What to expect |
+| --- | --- | --- |
+| 1080p SDR video | Supported | Recommended default path |
+| 4K SDR video or image | Supported | Higher preview/render cost; output resolution still follows the composition |
+| iPhone SDR video | Supported | Treated as normal browser-decoded SDR media |
+| iPhone HDR, HLG, or Dolby Vision-style upload | Partial | HDR metadata is detected and warned; the grading shader remains SDR |
+| HDR delivery render | Separate workflow | Use [HDR Rendering](/guides/hdr); grading controls are not HDR-aware |
+| LOG camera footage | Partial | Requires a known matching transform/LUT; no automatic camera profile management |
+| Full-scene grade including DOM/text | Not supported | Current grading targets individual media elements |
+| Face or region tracking | Not supported | Use a separate isolated media layer or external tracking/masking workflow |
+| Remote media | Partial | Requires compatible CORS headers; project-local assets are reliable |
+| ACES/OCIO finishing | Not supported | Outside the current browser shader pipeline |
+
+## Render and Performance
+
+The runtime creates a sibling WebGL canvas, uploads the current image/video
+frame as a texture, applies the same grading contract used by Studio, and hides
+the native source after a shader frame is ready. During final rendering,
+HyperFrames injects exact video frames and waits for the grading runtime to
+redraw before capture.
+
+For 4K output, follow [4K Rendering](/guides/4k-rendering). A 1080p source does
+not gain new detail merely because the composition is rendered at 4K.
+
+When animating a graded media layer's opacity, animate a wrapper rather than the
+`<video>` itself. The visible pixels are drawn by the sibling grading canvas,
+so wrapper opacity keeps the media and canvas together.
+
+Project-local media is the safest path. Remote media must provide compatible
+CORS headers and should use `crossorigin="anonymous"` when pixel access is
+required.

+title: Media Effects
+description: "Apply deterministic shader effects to video and image media, combine them with color grading, and animate supported strengths with GSAP."
+---
+
+Media Effects transform the pixels of a selected `<video>` or `<img>` beyond
+normal color correction.
+
+Blur, pixelation, VHS damage, ASCII, dither, halftone, engraving, crosshatch,
+and Kuwahara painting all run inside the same media shader used by
+[Color Grading](/guides/color-grading). Effects can be combined with correction,
+color grading, finishing, and a custom LUT in one validated payload.
+[Media Overlays](/guides/media-overlays) are separate editable composition
+layers.
+
+## Studio Workflow
+
+<Steps>
+  <Step title="Select real media">
+    Select a project-local `<img>` or `<video>` in the preview, Layers panel, or
+    Timeline. Effects do not appear for arbitrary divs or CSS background images.
+  </Step>
+  <Step title="Choose a starting point">
+    Preview an effect-bearing preset or open the Effects section. A preset is a
+    tested starting payload; it does not restrict further adjustment.
+  </Step>
+  <Step title="Tune the relevant controls">
+    Effects are grouped by intent: Essentials, Retro & Glitch, Print, and Art.
+    Enabling an effect uses a calibrated default, while its related controls
+    remain adjustable.
+  </Step>
+  <Step title="Choose a palette when supported">

+    authored two-to-six-color palette.
+  </Step>
+  <Step title="Verify motion and framing">
+    Play and scrub videos. Check at least the beginning, middle, and end when an
+    effect moves over time. Confirm that object-fit/object-position framing
+    remains correct.
+  </Step>
+</Steps>
+
+## Effect Families
+
+### Essentials
+
+| Effect | What it does |
+| --- | --- |
+| Blur | Defocuses or softens the complete media layer |
+| Pixelate | Converts the layer into a block mosaic |
+| Bloom | Adds thresholded glow around bright regions |
+
+### Retro & Glitch
+
+| Effect | What it does |
+| --- | --- |
+| Chroma Softening | Smears chroma while retaining central luma |
+| Tape Damage | Adds deterministic tracking errors, noise, ghosting, and dropouts |
+| Film Artifacts | Adds deterministic dust and short scratches |
+| Scanlines | Adds configurable horizontal display lines |
+| CRT Curvature | Warps media toward curved display geometry |
+| Channel Separation | Offsets color channels along an angle |
+| Digital Glitch | Combines line tears, blocks, displacement, pixelation, and channel split |
+
+### Print
+
+| Effect | What it does |
+| --- | --- |
+| Halftone | Renders source color through a print-dot raster |
+| Two-Ink Print | Reduces media to the built-in two-ink treatment |
+| Ordered Dither | Quantizes media into an ordered limited palette |
+| Mono Screen | Builds monochrome dot, shape, or line artwork |
+
+### Art
+
+| Effect | What it does |
+| --- | --- |
+| ASCII | Renders media as configurable procedural glyph cells |
+| Engraving | Translates luminance into directional engraved lines |
+| Crosshatch | Translates media into layered hand-hatched lines |
+| Kuwahara Paint | Applies edge-preserving painterly smoothing |
+
+## Effect-Bearing Presets
+
+`Creator Camcorder`, `VHS Playback`, `8mm Home Movie`, `Editorial Halftone`, and
+`Two-Ink Print` provide tested combinations of effect, correction, and
+finishing settings. Preview one as a starting point, then tune the underlying
+controls. They are normal shader payloads, not baked media or bundled LUTs.
+
+## Agent Workflow
+
+Agents should discover only the part of the toolbox relevant to the user's
+intent:
+
+The user may simply ask for _"an old home-video feel"_, _"a useful privacy
+reveal"_, or _"something more graphic for this poster."_ The `media-use` skill
+classifies that intent, then queries the narrow effect or recipe details instead
+of loading the exhaustive contract.
+
+```bash Terminal
+hyperframes media-treatment --capabilities --json
+hyperframes media-treatment --capability retro-glitch --json
+hyperframes media-treatment --capability digitalGlitch --json
+```
+
+The concise overview lists capability families. A focused query returns the
+effect's calibrated apply payload, controls, render lane, palette support, and
+seek-safe animation path. Use the canonical payload instead of guessing
+sub-control defaults.
+
+Apply a complete, validated combination in one mutation:
+
+```bash Terminal
+hyperframes media-treatment \
+  --project . \
+  --file compositions/scene.html \
+  --selector '#hero' \
+  --grading '{
+    "adjust":{"contrast":0.05,"highlights":-0.06},
+    "effects":{
+      "tapeDamage":0.65,
+      "tapeTracking":0.55,
+      "tapeNoise":0.25,
+      "tapeSpeed":0.5,
+      "scanlines":0.2
+    },
+    "details":{"grain":0.08,"vignette":0.06}
+  }' \
+  --apply \
+  --json
+```
+
+Recipes are tested shortcuts, not a closed list. An agent may assemble a custom
+payload when the source and intent justify it, but it should:
+
+1. Choose one primary visual intent.
+2. Query the exact effect or family contract.
+3. Add only controls that visibly support that intent.
+4. Avoid stacking several dominant stylizations without a reason.
+5. Verify representative frames and a short render.
+
+## Palettes
+
+`palette` accepts two to six exact `#RRGGBB` colors in authored order.
+Dark-to-light order creates normal luminance mapping; reversing the array
+intentionally inverts that mapping.
+
+```json
+{
+  "effects": {
+    "dither": 1,
+    "ditherSize": 0.5
+  },
+  "palette": ["#080717", "#3c185f", "#d9339f", "#ff6b66", "#aafae0"]
+}
+```
+
+Compatible effects are ASCII, Ordered Dither, Mono Screen, Engraving, and
+Crosshatch. A palette alone does not activate an effect.
+
+Discover built-in palettes without copying their values into instructions:
+
+```bash Terminal
+hyperframes media-treatment --capability palettes --json
+hyperframes media-treatment --capability electric-ink --json
+```
+
+## Animation and Keyframes
+
+The following paths have seek-safe CSS custom properties and may be animated by
+a paused, registered GSAP timeline:
+
+- Global treatment intensity
+- LUT intensity
+- Exposure
+- Blur
+- Bloom
+- Kuwahara Paint
+- Pixelate
+- ASCII
+- Ordered Dither
+
+Example blur-to-focus reveal:
+
+```html index.html
+<div
+  class="clip"
+  data-composition-id="media-effect-demo"
+  data-start="0"
+  data-duration="4"
+>
+  <video
+    id="hero"
+    src="assets/hero.mp4"
+    muted
+    playsinline
+    style="--hf-color-grading-blur: 0.8"
+    data-color-grading='{"effects":{"blur":0.8}}'
+  ></video>
+</div>
+
+<script>
+  const tl = gsap.timeline({ paused: true });
+  tl.to(
+    "#hero",
+    {
+      "--hf-color-grading-blur": 0,
+      duration: 1.2,
+      ease: "power2.out",
+    },
+    0,
+  );
+  window.__timelines = window.__timelines || {};
+  window.__timelines["media-effect-demo"] = tl;
+</script>
+```
+
+Author the initial custom-property value inline. Do not use timers, unseeded
+randomness, frame-zero `set()` calls, or `onUpdate` callbacks. Query an effect's
+focused capability to get its exact animation property and range.
+
+Tape damage, digital glitch, film artifacts, and similar effects may contain
+deterministic internal motion even when their overall strength is not one of
+the keyframeable paths above.
+
+## Important Effect Behavior
+
+- **Tape Damage** is the primary analog-tape amount. Tracking controls moving
+  tears, Noise controls row jitter/noise, and Speed controls their deterministic
+  motion. Those subordinate controls do not activate tape damage by themselves.
+- **Film Artifacts** adds sparse deterministic dust and scratches. Grain,
+  vignette, color, and optional seek-safe gate weave are separate choices.
+- **Halftone** uses fixed print-oriented channel angles and edge behavior.
+  Cell size remains adjustable.
+- **Two-Ink Print** is HyperFrames' own fixed two-ink mapping. Do not describe
+  it as a named commercial print process or stack it with Halftone by default.
+- **ASCII** uses procedural glyph cells. Size, style, ink behavior, rotation,
+  and a compatible palette remain configurable.
+- **Ordered Dither** uses a temporally stable 4x4 Bayer matrix. It is not
+  Floyd-Steinberg or another sequential error-diffusion algorithm.
+- **Bloom** extracts bright regions before blurring them; it is different from
+  raising highlights or whites.
+- **Kuwahara Paint** smooths regions while preserving major edges. Radius,
+  sharpness, and saturation shape the result.
+
+## Deterministic Pipeline Order
+
+HyperFrames evaluates combined treatment stages in one fixed order:
+
+1. Source framing and multipass Blur/Kuwahara preparation
+2. Chromatic and digital-glitch transforms
+3. Primary correction, color grading, and LUT blended by global intensity
+4. Grain and film artifacts
+5. Mono, engraving, crosshatch, halftone, two-ink, dither, and ASCII
+6. Bloom, scanlines, vignette, and CRT display masking
+7. Before/after comparison
+
+The order cannot currently be rearranged. A fixed order keeps Studio,
+playback, seeking, and final rendering deterministic and prevents agents from
+inventing incompatible effect graphs.
+
+## Performance
+
+Performance follows the number of treated pixels and the selected render lane,
+not only the number of elements.
+
+- Blur, Bloom, and Kuwahara use multipass rendering.
+- Several tiled media elements can be cheaper than several overlapping
+  full-frame elements.
+- When more than two full-frame multipass-treated elements are visible
+  together, verify continuous playback on the target machine.
+- Simplify or pre-render a stack when preview frames drop.
+- Kuwahara uses bounded half-float intermediate targets when supported and
+  otherwise reports itself unavailable.
+
+For 4K delivery, verify the effect at the final composition size. Resolution-
+aware effects preserve their intended scale, but 4K still processes more pixels
+than 1080p.
+
+## Low-Level Data Shape
+
+Media effects live in the same persisted contract as grading:
+
+```html index.html
+<img
+  id="poster"
+  src="assets/poster.jpg"
+  data-color-grading='{
+    "effects":{
+      "ascii":1,
+      "asciiSize":0.066,
+      "asciiStyle":0,
+      "asciiColor":1,
+      "asciiRotation":0
+    },
+    "palette":["#001100","#00ff00"],
+    "colorSpace":"rec709"
+  }'
+/>
+```
+
+Unknown keys are rejected and values are normalized by the Core contract. The
+CLI should remain the primary authoring surface for agents.

+title: Media Overlays
+description: "Add editable, timeline-driven HUD, flash, light-leak, and freeze-frame dressing above video or image media."
+---
+
+Media Overlays are authored HyperFrames composition blocks that sit above a
+video or image.
+
+They add visual dressing such as a recording HUD, camera flash, light leak, or
+freeze-frame treatment without baking those pixels into the source media.
+Unlike [Color Grading](/guides/color-grading) and
+[Media Effects](/guides/media-effects), overlays are not shader properties.
+They are real HTML, CSS, and paused GSAP timelines installed from the
+HyperFrames Registry. Once inserted, they remain normal editable layers in the
+composition.
+
+## Shipped Overlays
+
+| Registry block | Purpose |
+| --- | --- |
+| `camcorder-hud` | Responsive REC indicator, battery, editable date placeholder, and timeline-driven counter |
+| `editorial-flash-overlay` | Finite neutral-warm light layers for a camera-flash cut or social reveal |
+| `organic-light-leak-overlay` | Finite CSS light leak for memory beats and motivated transitions |
+| `freeze-frame-dressing` | Timeline-driven paper, tape, and flash dressing for a freeze frame or background-removed subject |
+
+These are first-party authored blocks. Their Catalog poster/video assets are
+previews only; the installed result is editable composition source.
+
+## Studio Workflow
+
+<Steps>
+  <Step title="Select the media beat">
+    Select the `<video>` or `<img>` the overlay should accompany.
+  </Step>
+  <Step title="Open Overlays">
+    The Design panel shows responsive preview cards for media-treatment overlay
+    blocks from the Registry.
+  </Step>
+  <Step title="Insert a block">
+    Choose an overlay. Studio installs its composition source, aligns it to the
+    selected media's start and duration, and places it on the next known visual
+    track.
+  </Step>
+  <Step title="Edit it as a normal layer">
+    Use Layers, Timeline, Design, or Code to change text, timing, color,
+    opacity, animation, or placement. Removing the overlay does not alter the
+    underlying media treatment.
+  </Step>
+  <Step title="Verify the complete beat">
+    Play and scrub through the overlay's entrance, hold, and exit. Check the
+    final render because the overlay, source media, and shader treatment are
+    separate compositing layers.
+  </Step>
+</Steps>
+
+The left Catalog remains the browse-all Registry surface. The Overlays section
+is the media-focused shortcut for the selected beat.
+
+## Agent Workflow
+
+An agent may combine grading, a shader effect, treatment animation, and an
+overlay when they support one coherent intent. It should not treat them as
+mutually exclusive.
+
+For example, a restrained camcorder treatment can combine:
+
+1. A small source correction.
+2. Chroma softening and tape damage on the media.
+3. The `camcorder-hud` Registry block above it.
+4. A finite reveal or exit timed to the edit.
+
+Discover overlays through the media-treatment overview:
+
+```bash Terminal
+hyperframes media-treatment --capabilities --json
+```
+
+Install one through the Registry:
+
+```bash Terminal
+hyperframes add camcorder-hud --no-clipboard
+hyperframes add organic-light-leak-overlay --no-clipboard
+```
+
+The command installs composition source under the project. The agent then
+embeds and times that sub-composition according to the host composition's
+normal rules.
+
+Agents should:
+
+- Use an overlay when it adds information, motivated light, or useful visual
+  language.
+- Keep text and HUD fields editable.
+- Align finite overlays to a deliberate beat rather than leaving them active
+  for the entire video.
+- Avoid adding decorative overlays automatically to accuracy-sensitive,
+  brand-sensitive, or deliberately clean footage.
+- Verify that the overlay does not obscure captions, faces, product UI, or
+  essential content.
+
+## Choosing the Right Overlay
+
+### Camcorder HUD
+
+Use for creator-camera, home-video, recording, or found-footage language. The
+counter is timeline-driven and the REC behavior is deterministic. Edit the
+date/label placeholders instead of rendering arbitrary timestamp text into the
+source media.
+
+### Editorial Flash
+
+Use as a short cut accent or social reveal. It is finite by design and should
+land on a motivated edit, capture, pose, or beat. It is not a permanent glow or
+a replacement for shader Bloom.
+
+### Organic Light Leak
+
+Use sparingly for memory, warmth, film-language transitions, or a motivated
+light event. It is a CSS/GSAP overlay rather than a LUT and does not permanently
+change source color.
+
+### Freeze-Frame Dressing
+
+Use with a held frame or a subject cutout. The block provides paper, tape, and
+flash dressing; it does not perform background removal itself.
+
+For a transparent subject:
+
+```bash Terminal
+hyperframes remove-background subject.mp4 -o subject.webm
+hyperframes add freeze-frame-dressing --no-clipboard
+```
+
+See [Remove Background](/guides/remove-background) for cutout and background
+plate behavior.
+
+## How Overlays Combine with Pixel Treatments
+
+The compositing model is:
+
+```text
+source <img>/<video>
+  -> color correction and grading
+  -> LUT and shader effects
+  -> visible media canvas
+  -> HTML/CSS/GSAP overlay layers above it
+  -> captions and other composition layers
+```
+
+Color grading does not recolor overlay text or graphics. This is intentional:
+HUD labels remain crisp, captions remain readable, and an organic light leak
+can be adjusted independently from the source grade.
+
+If an overlay should appear behind a subject, separate the subject into its own
+transparent media layer and place the overlay between the background and
+foreground layers.
+
+## Editing and Reuse
+
+Registry overlays are copied into the project rather than fetched at render
+time. This keeps rendering deterministic and lets teams:
+
+- Change the HTML and CSS.
+- Replace labels and colors.
+- Retune the paused GSAP timeline.
+- Reuse the block across multiple compositions.
+- Remove it without changing the media's `data-color-grading` payload.
+
+Keep host-specific timing and placement in the host composition when possible.
+That preserves the Registry block as a reusable visual unit.
