- Skip IVF for archival masters: lossy compression discards detail, so keep the WebM original.
- Flatten transparency first: IVF has no alpha channel, so composite WebM over a background color.
Limits
Starting point: WebM - VP9 video with Opus audio and alpha support. Apple editors accept it unevenly; keep MP4 for editing round-trips. Audio is not supported, so only the picture carries over. Encode IVF (VP9) from WebM at a bitrate near the source, and confirm the audio track before converting.
