When not to convert MOV to SWF
- Skip SWF for archival masters: lossy compression discards detail, so keep the MOV original.
- Flatten transparency first: SWF has no alpha channel, so composite MOV over a background color.
Limits
Starting point: MOV - QuickTime camera files with ProRes or H.264. Some codecs inside need transcoding before browser playback. Only the embedded video track converts; scripts and buttons are dropped. Encode SWF (Sorenson Spark / MP3) from MOV at a bitrate near the source, and confirm the audio track before converting.
How conversion works
Conversion runs entirely in your browser with FFmpeg WASM. Files never leave your device.
