I had a bunch of video files in the .VOB format which I copied from a few DVDs a couple of years back. Uploading them on a cloud storage service (e.g Google Drive, OneDrive etc) for safe keeping is nice but not practical since they cannot be played directly through the cloud service's video player. The latter would play .MP4 video files.

FFMPEG comes handy here to convert the video files.

ffmpeg -i bla.vob -b:v 3000k -b:a 256k bla.mp4

I used mediainfo to find the maximum video & audio bit rate.
