I work at a multimedia company where most people work on Mac OS X, but I use ubuntu linux at work a lot, and I work at home a lot, where ubuntu is my only OS. I need to be able to transcode video files from MPEG-2 and 4, and also hopefully straight from DVD to quicktime format, readable by apple quicktime (without divx or any other plugins that my co-workers never bother with). I can get good MPEG-2 VOBs with DVD::Rip, but can't transcode the files.
I have done my best to get there with Cinelerra, and command-line ffmpeg and mencoder.
Cinelerra quits as soon as I start rendering to quicktime4linux, leaving behind a .mov with the requested filename, but which is less than 1KB - clearly not the answer.
I know that ffmpeg is capable of doing the transcoding I need, because I can do it with ffmpegX on OS X using ffmpeg as the codec library. When I tried it from the command line in linux, I got the following:
Code:
$ ffmpeg -i movie.vob movie.mov

And with mencoder I got the following:

I will be happy to find out what I am doing wrong in any of these three programs, but I'd ultimately like to learn to use all three.
Thanks in advance,
