When not to convert WebM to TS

Skip TS for archival masters: lossy compression discards detail, so keep the WebM original.
Flatten transparency first: TS 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. Captures may start mid-packet; trim the lead-in after conversion. Encode TS (H.264 / AAC) from WebM at a bitrate near the source, and confirm the audio track before converting.
