alternative to handbrake? to convert video to mpg4

[chris1497]

I'm currently using handbrake (with the gui) to convert some video files to mpg4. It takes about 2 hours to convert an average movie is there anything a little speedier? I'm running a core2duo processor.

file types:
.vob ----> .m4v

I'm also open to cli suggestions.

If you don't have problems using the terminal, you should try ffmpeg. Here's a youtube tutorial.

Regards.

Thanks for the response. I looked into ffmpeg before, but couldn't seem to get it to work, despite looking at a few different tutorials.

The tutorial doesn't explain what the video container is?

here is my attempt:

ffmpeg -i MOVIE.VOB -vcodec vob -sameq MOVIE_FINAL.mp4

Seems stream 0 codec frame rate differs from container frame rate: 59.94 (60000/1001) -> 59.94 (60000/1001)
Input #0, mpeg, from 'WAR.VOB':

clearly I'm messing up something with the audio

tried this:

ffmpeg -i WAR.VOB -acodec ac3 -sameq output.mp4

There is a lot of output, but these arein red and seem bad:

[ac3 @ 0x157c710]frame sync error

Bit allocation failed. Try increasing the bitrate.
