Starting point: MPV - MPV holds elementary MPEG video streams without a container wrapper. No audio can be stored, so pair it with a separate track. Server metadata drops on export; the picture and sound carry over. Encode GXF (MPEG-2 / PCM) from MPV at a bitrate near the source, and confirm the audio track before converting.
