There are ten creation workflows. The Workflows nav group held eight of them plus
`guides/export-and-share`, which is not a workflow at all — there is no such
skill, it is a finishing task. The tenth, the Remotion port, sat under
Developers > Composition, design & animation, a different tab entirely.
So: export-and-share moved to Build the project where the other task pages live,
the Remotion page moved into Workflows, and the chooser gained a tenth route. The
chooser rendered `<video>` unconditionally, which would have drawn a black
rectangle for a route with no clip — it now renders a neutral tile instead, and
custom.css styles it to the same box.
**The Prompt Guide and the workflow guides did not know about each other.** Level 1
is organised one page per workflow, and five of its six pages linked to no guide
at all. A reader learning to prompt for motion graphics never discovered
/guides/motion-graphics, and the traffic went nowhere in both directions. Each
Level 1 page now names its workflow and says what that page adds.
Four links pointed at redirects rather than the real page — /guides/claude-design,
/guides/common-mistakes, /guides/website-to-video, /guides/media-overlays. Seven
files now link to the destination directly.
Checked after: 0 broken links, 0 links via redirect.
Thirty-two published videos were the raw render output. One 20-second catalog
preview was 60 MB at 25 Mbps — Blu-ray bitrate for a screen capture in a docs
page. Nothing autoplays, so no page shipped that silently, but a reader who
pressed play paid for it.
Re-encoded at 1280 wide, CRF 28, faststart, keeping audio where it existed.
Measured PSNR against the originals at ~38.5 dB, which is visually identical —
the first check I ran returned nothing and I mistook that for a pass, so this
number comes from a filter that actually worked.
Worth correcting one thing I said earlier: the catalog is not systemically
over-encoded. 190 videos, 0.36 GB, about 1.9 MB each. Six were over 10 MB. I
found two monsters and generalised from them.
Pages carrying more than 8 MB of video: 26 before, and the heaviest went from
140 MB to under 15 MB.
The durable fix is in generate-catalog-previews.ts, which had no delivery encode
at all — it published the render master directly. It has a web pass now, so the
next preview is born small instead of being cleaned up later.
Both went to /guides/color-grading anchors that the guide rewrite removed. The
content did not disappear — it lives on /reference/color-grading as 'Animate a
supported property' and 'Limit a grade to part of the frame'. A reader clicking
either landed on the right page and scrolled nowhere.
mint broken-links does not check anchors, so CI would never have caught this.
Three things the quality layer asserted but the pages did not support.
changelog-process said "do not recreate docs/weekly-updates.mdx; that empty
public page was retired" while the page exists with a real curated feed. It
describes the page as it is: unlisted, reachable by URL and RSS, with versioned
notes still in the Changelog.
The Related-topics rule read as universal, but three different endings are in
use and each is right for its shape — Related topics on task pages, a single
Next line through the Prompt Guide's numbered sequence, and nothing on
reference and concept pages. The rule now says that, and every section matches
it; color-grading gained the Next line it was missing and no longer points at a
page this stack retired.
The vocabulary previews were 18 DocsVideo players in three unlabelled grids, so
a reader saw several near-identical clips with no way to tell smooth from
snappy. They are now native muted loops with visible captions, which is what
AGENTS.md asks for small preview loops in the first place.
Both pages explained intensity's independence by saying details and
effects are applied after the u_intensity mix. The conclusion was right
but the mechanism was wrong for several families.
Verified in the shader: applyCrtWarp runs on the uv before sampling;
sampleMedia itself carries pixelate, chromaBleed and the tape family;
sampleChromaticMedia and applyDigitalGlitch shape sampleColor — all
before the mix at runtime/colorGrading.ts:1234. Only grain,
filmArtifacts, monoScreen, engraving, crosshatch, halftone, twoInkPrint,
bloom, scanlines and vignette run after it.
Pre-mix effects are already present on both sides of
mix(sampleColor.rgb, applyColorGrade(sampleColor.rgb), u_intensity), so
intensity does not scale them either. Both pages now say details and
effects sit outside the mix — some before, some after — without making
the ordering the reason.

Both pages said intensity does not scale a grade and that 0.5 renders the
same as 0. That is wrong, and the error was mine: I tested intensity only
against twoInkPrint and tapeDamage, then generalised from an effects-only
result.
The shader mixes ungraded against graded at u_intensity
(runtime/colorGrading.ts:1234), so it does scale adjust, wheels, curves,
hueCurves, secondaries and the LUT. Runtime tests pin 0.25 and 0.75
reaching the uniform. What it does not scale is details and effects —
grain, filmArtifacts, monoScreen, engraving, crosshatch, halftone,
twoInkPrint and the tape/CRT families are all applied after that mix
(:1235-1262), which is exactly what I had measured.
Both pages now say intensity ramps the primary grade only, and to animate
the specific effect when the look is effect-based.

- Repoint the generated-artwork exit bridge at color-grading. The nav
inserted the new page between generated-artwork and vfx-and-liquid-glass
but the "Next" link still skipped it (miga-heygen, blocking).
- Correct the LUT custom property name: --hf-color-grading-lut-intensity,
not --hf-color-grading-lut. Real transcription error, surfaced while
checking the CSS-variable review comment against the source table in
packages/core/src/colorGrading.ts:921-931.
- Add #t=0.1 posterframe hints and a contextual italic caption to all ten
videos, matching the sibling prompting chapters.
- Reconcile British spelling to American throughout. The file path, nav
slug, page title and every cross-reference were already "color".
- De-duplicate the animatable-effect caveat list: the chapter now links to
the guide's Animating a Grade section instead of restating which effects
are verified working, so the list is maintained in one place.

Ten A/B demos, each with the plain-language prompt that produced it and
the payload it compiled to. Slots into Level 4 — Substance.
The chapter teaches technique and leaves the key/bound reference to the
Colour Grading guide rather than duplicating it.
Also adds two sections to docs/guides/color-grading.mdx:
- Animating a Grade — the nine CSS custom properties, plus driving the
payload from the timeline for effects that have none. Documents that
--hf-color-grading-intensity does not scale a grade at render time,
and that payload-rewrite animation is effect-dependent: verified
working for halftone and twoInkPrint, verified not working for
crtCurvature, scanlines, chromaBleed and chromaticAberration.
- Limiting a Grade to Part of the Frame — grading qualifies by value,
never by screen position, so a region has to become its own layer.
Includes the three layer recipes and a worked face-redaction example.
Previously the support matrix said "not supported" with nowhere to go.
Renders are served from the CDN; docs/images/ is gitignored.
