zooqueenandHanzo Dev 70b41673a3 frames: rebrand the fork to Hanzo Frames
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.

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 (the com.apple.quicktime.author QuickTime 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 -an to preserve the original VFR timestamps.
  • Recorded content: the public hanzoai/frames GitHub repo root page. No private, proprietary, or user-identifying content.

Properties preserved from the original

  • r_frame_rate: 120/1
  • avg_frame_rate: ~36.1fps (21720/601)
  • isVFR: true (70% delta vs r_frame_rate, well over the 10% threshold in ffprobe.ts)
  • Pre-fix duplicate-frame rate: ~34% on a mid-file 3s segment extracted at 30fps — matches the 18–44% observed across segments of the full recording.
