Forked from HyperFrames (Apache-2.0), full history preserved. Hosts are mapped explicitly and BEFORE the identifier rename, because hyperframes.heygen.com is not decoration: 175 of its occurrences are $schema identifiers that a validator dereferences. A blind rename would have left them naming a host that never serves them. The schema files are in this repo under docs/schema, so the mapped host is one we can actually serve -- that is the condition that makes the rewrite safe, and serving them is a deploy task, not an edit. docs/schema/hyperframes.json is renamed to frames.json to match the identifier it is now published under. api.heygen.com and the CLI auth against heygen.com are left UNRENAMED on purpose. They are a dependency on HeyGen's SaaS, not a name of ours to take, and the right move is to remove that integration rather than rebrand it. LICENSE and CREDITS.md are untouched; NOTICE records the lineage. Co-authored-by: Hanzo Dev <[email protected]>

src/clip.mp4 is a 5-second excerpt from a macOS ScreenCaptureKit (ReplayKit)
recording, used here as a regression fixture for the VFR (variable-frame-rate)
freeze bug fixed in PR #360.
- Original duration: 21s, recorded via
ReplayKitRecording(thecom.apple.quicktime.authorQuickTime tag identifies this). - Excerpt: 16s–21s of the original, downscaled from 2746×1902 to 480×332,
re-encoded with
ffmpeg -fps_mode passthrough -c:v libx264 -preset slow -crf 28 -anto preserve the original VFR timestamps. - Recorded content: the public
