Skip 3G2 for archival masters: lossy compression discards detail, so keep the WebM original.
Flatten transparency first: 3G2 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 resampled to the handset profile, so keep a master copy. Encode 3G2 (H.264 / AAC) from WebM at a bitrate near the source, and confirm the audio track before converting.
