Measured across all 136 hand-written pages, the twelve hardest to read were all
in prompting/. These ten were untouched — 29% to 40% of their sentences ran over
28 words, against a site median under 15%.
media-and-audio 39.7% -> 6.2% 15 semicolons -> 6
visual-specs 37.1% -> 19.0% 11 -> 9
weekly-updates 39.1% -> 0.0%
runtimes-and-3d 34.1% -> 17.5%
design-systems 34.0% -> 4.3%
recreating-references 33.3% -> 7.3% 16 -> 1
storyboards 31.9% -> 5.4%
variables-and-templating 30.3% -> 7.3%
generated-artwork 29.4% -> 9.1%
explainers 29.1% -> 3.3% 12 -> 1
Word counts barely move — 1752 to 1748, 1633 to 1617 — which is the point. The
facts and worked examples all survived; the sentences carrying them got shorter.
weekly-updates is an archive, so no date, version or fact changed there at all.
One anchor came back: capstone#the-full-prompt-verbatim, which these pages link
to and which an earlier commit had already moved to #the-prompt-word-for-word.
Repointed. Branch total: 0 broken pages, 0 broken anchors.
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.
Five-way review of the section against docs.json, catalog pages, and
skills. Fixes: stale /hyperframes-media skill row (real name /media-use)
plus missing music-to-video and slideshow workflow rows; caption
identity misattributions (keynote/documentary are scene-embedded, stomp
carries no rail); prompts violating the guide's own ambient-idle rule;
grounded keying rationale (u2net_human_seg); broken forward references;
nested-backtick code spans; brand casing and frontmatter dash
consistency throughout.

Moves all 28 example/validation renders to the docs' canonical media
host (s3://heygen-public via scripts/upload-docs-images.sh) and points
every embed at static.heygen.ai instead of HeyGenVerse asset URLs.

Runs validation builds for the primary prompt on every new feature page
(all pass lint/validate/render) and applies the fixes they surfaced:
lower-third exit-length note, block-adaptation framing on the anatomy
technique slot, code-typing per-character wording, caption-component
demo-content note, map determinism/merge-at-source notes, device-mockup
demo-UI expectation, variables img clarification. Embeds 29 unedited
renders next to their prompts (HeyGenVerse-hosted), including a
default-vs-overridden pair demonstrating variables.

Splits guides/prompting into a Prompt Guide nav group (overview + Fundamentals
+ Making it look good, 11 pages) with a redirect from the old URL. Applies
research-validated upgrades: beat content formula, before/after prompt rewrites
with engine rationale, single-variable iteration moves, absolute-target
calibration, camera/depth/pacing vocabulary, prerequisites gate.
