Starting point: MPEG - MPEG is the ISO program-stream container behind MPEG-1 and MPEG-2 discs. Interlaced sources may need deinterlacing for clean playback. Only the embedded video track converts; scripts and buttons are dropped. Encode SWF (Sorenson Spark / MP3) from MPEG at a bitrate near the source, and confirm the audio track before converting.
