I have an MKV file with various softsubs built in - but what do I have to do to get these hardsubbed into an MP4? I know they have to be re-encoded, which I tried. I demuxed the video and subs, muxed them back together into an MP4 and then tried to convert it in Visualhub - which didn't work, cus I just ended up with a converted MP4 with no subs.
Any tips?
