**`declareVariable`'s field is `declaration`, not `decl`.** Documented wrong in
three places across two SDK reference pages. This one fails *silently* — the
handler reads `op.declaration`, gets undefined, and returns EMPTY at
sdk/src/engine/mutate.ts:991. No throw, no patch, no error. A reader copies the
example and nothing happens. types.mdx opens by claiming it was verified against
types.ts, which is where the correct name is (line 134).
**Colour grading says eighteen presets; the Grade panel has thirteen.** Eighteen
is the combined total. The other five carry effects and live in the Effects
panel — colorGrading.ts derives GRADE_PRESETS by filtering EFFECT_PRESETS out,
and colorGrading.test.ts:25 asserts VHS Playback is *not* in Grade. I wrote that
sentence today and used VHS Playback as the example, so the page sent a reader to
Grade looking for something that is not there. The visual brief further down had
the same error baked in; fixed before anyone shoots it.
**`hyperframes render` on a slideshow does not fail — it lies.** The page said
export "is not currently supported", which reads like the command errors. The
skill is emphatic: a deck has no master root composition, so render resolves only
the first slide and writes a silently truncated MP4 — six seconds of a
forty-second deck, no warning. That is now a Warning saying exactly that.
I also swept every documented edit-operation field against sdk/src/types.ts.
Six looked wrong and five were my regex not stripping the `?` optional marker;
`easeEach` and `resolvedSelector` are real, at types.ts:178-179. One genuine
error out of that sweep, the one above.
Removing the eight-second teaser left this page with nothing at all, and the
replacement had been rendered and published hours earlier without ever being
wired in.
Twenty-seven seconds of a live deck: fragments arriving one key-press at a time,
a hotspot jumping to a branch slide, the back control returning to the exact
fragment it left, and presenter mode with real notes and a running timer. It is a
capture of the deck running, not a video of slides.
Guides with nothing to look at: 5.
Product launch, colour grading, faceless explainer, captions and recuts, motion
graphics, and voice and audio.
Five of these led with a six-to-eight second teaser. A six-second clip on the
page that teaches you to make explainers does not teach anything — it is a
placeholder that looks like content. Colour grading, the most visual feature in
the product, had no video at all.
The new films are 34 to 41 seconds and each shows a RANGE rather than one look:
four ways to tell the same idea with no footage; five caption treatments on one
untouched clip; correction, presets, curves, selective colour, all four scopes
and a LUT; narration with music ducking under it and effects on the beat. The
launch film is built by running the workflow on huly.io for real, so the page
that sells the workflow is showing its actual output.
They share one visual system, measured from HyperFrames own light-theme launch
films rather than invented: bone field, near-black type, coral accent, and the
product always a dark panel inset on the light field. Every one carries audio at
about -20 dB and is 1-2 MB.
The old teasers are removed from the three pages where they became a duplicate.
They stay in the workflow picker, which is where a six-second tile belongs.
Guides with nothing to look at: 15 at the start of this work, 5 now.
Ten videos on the docs site played in silence. The player is click-to-play, so a
reader deliberately starts them and gets nothing — which reads as broken rather
than as a stylistic choice.
The music is from HeyGen's own catalogue, pulled through the media-use skill's
resolve path with the account already authenticated on this machine. That matters
more than convenience: the launch projects on disk carry a `launch-music-trimmed.mp3`
with no licence, no attribution and no metadata, and three Pixabay tracks. Neither
belongs on the official docs CDN, where objects cache immutably for a year.
Mixed at roughly -22 to -24 dB mean so it sits under the picture. Getting there
took two corrections worth recording: proportional fades, because a 1.2s fade-out
on a 5s clip eats half the audio; and seeking 11s into the bed, because its first
ten seconds are a quiet intro that dragged every short clip down to -27 dB.
The three Examples tiles are left silent on purpose — they are muted autoplay
loops, so an audio track would only be weight.
Verified: every video referenced anywhere under docs/ that is not a muted
autoplay tile now has an AAC stream, checked against the live CDN URL rather than
the local file.
Adds the pages the rebuilt navigation is organised around, and moves the sidebar
onto that structure. Every entry points at a file that exists after this commit;
nothing is rewritten or removed yet, and no redirect is claimed yet.
- Studio (13 pages) — the editor had no section of its own
- One guide per creation workflow, matching the shipped agent skills
- Section hubs: Concepts, Catalog, Developers, Deploy, Workflows, Help,
Go further, Product updates, 30 Days of HyperFrames
Pages a later commit retires drop out of the sidebar here but still exist and
still resolve, so the site stays navigable at this commit.
Incidentally fixes a link to /concepts from the Lambda migration guide that is
broken on main today — the destination did not exist.
