jperrello source-credit
Persistent attribution overlay. "Original video:" in Sapphire Glow (#2E6BFF), the
source video's title in white, baked in at the same vertical band as a TV
chyron. Same renderer pattern as burn-subtitles / title-transition
(PIL PNG, ffmpeg overlay) because the local ffmpeg has no libass/drawtext.
Invoke
.claude/skills/source-credit/source-credit.sh <input> <ingest.json> <out>
input: video to overlay onto (any aspect ratio; designed for 1080x1920)ingest.json: source video metadata (readstitle)out: output mp4
Output
mp4, same dimensions and duration as the input, video re-encoded, audio
stream-copied. Cache: <out>.scmeta records the title signature; rebuild
only when input or title changes. Prints the output path to stdout.
Geometry
Banner is positioned with its top at y = 4% of frame height. For a 1080x1920 short this puts the credit around y=77 (a top chyron). Captions now live in the lower third (≈y=1344) and the title card pops in centered, so the credit collides with neither. Font auto-fits from 58pt down to 38pt (2pt smaller than the prior 60→40 range). Banner width auto-fits to the title; long titles wrap to a second line.
