I used to use MPEG Streamclip to merge multiple clips and convert them to an mp4 in the process, and do a whole batch list at the same time. Since I have upgraded machines, MPEG Streamclip no longer works on Mountain Lion OSX, so I need an alternative program! Every program I find either can only let me batch convert, or merge the clips. I can't do both. Any thoughts???
If nothing exists, whats the fastest compressor out there?
