How to combine MP4 videos into one large single file

Aug 15, 2012 by lindairion

“I have 21 minute TV shows, divided up in to 3 clips seven minutes each. I need to merge them or join them into one large clip in mp4 format, the three clips are mp4 format. I tried Mediacoder, but that re-encodes them so it takes about a half hour.. I have 50 shows so thats not possible.. I need to merge the clips losslessly so it should be quick. I know YAMB can do this, but when I try, part 1′s audio shows with video from part 2. I don’t know how to fix it.”

“I have two high-quality mp4 files, which are of two parts of the same show. I want to merge them together into 1 file, and I usually use VirtualDub to merge my files… But it doesn’t seem to support mp4. What alternatives are available (especially ones that don’t require re-encoding)?”
