OK, I know you need to transcode video to MPEG2 (or MPEG1) as the MVP plays that natively, but what is the story with audio? In the past I have just transcoded the audio to mp2 as that is what I read others have done and it has worked well many times for me.
But if I have an Xvid that already has audio in MP3 format (and IIRC the MVP does both mp2 and mp3 natively), can I forgo the audio transcode completely (this is an option in GUI4ffmpeg) ?
- Will it be a (much) faster transcode if I say video only?
- Will it likely still be in sync if I choose NOT to trasncode the audio, as I understand the audio/video transcodes would split the two streams and remux them back together, so presumably keeps up with the audio sync in doing so?)
[EDIT]Well, that was weird. When I turned off the option to transcode audio, it said I could only save the file as a Video Stream (m2v). Looks like I misunderstood what they meant about that option...
When I turned it on and tried to choose mp3, it always flicked back to ac3 (which I know it cannot do, at elast not without the mvpmc domgle). So mp2 was the only option anyway ....
