Date: 2008mar13 Product: ffmpeg, Premiere Q. How do I a convert a VOB (that was ripped from a DVD) into a usable high quality video for use in Premiere? A. Renaming the .VOB to .MPG nearly works. When I try to import such a file into Premiere there is no audio. To make it usable, convert it to a .WMV file with ffmpeg like this:

ffmpeg -qscale 1 -i infile.vob -f asf -vcodec wmv2 -acodec adpcm_ima_wav outfile.wmv

Where infile.vob is the input file and outfile.wmv is the output file. The output file is about the same size as the input file but can be imported into Premiere. For me at least, the video couldn't be played in Window Media Player... which is too bad but wasn't the point. Takes several hours.
