Limits

Starting point: WebM - VP9 video with Opus audio and alpha support. Apple editors accept it unevenly; keep MP4 for editing round-trips. Tiny palettes remap on export; expect shifted colors. Encode FLI (H.264 / AAC) from WebM at a bitrate near the source, and confirm the audio track before converting.
