Free program to merge 2 video files??

[Armageddon415]

Anyone know of a free program that can merge 2 video files?

 

[MrScott81]

what kind of video files?

you might check out VirtualDub for plain AVI's or TMPGEnc for mpeg.

MPEG streams can usually be merged just by joining the files with cat on unix or copy on windows.

AVI containers are more complicated because you usually have to transcode one of them to have them both use the same audio and video codecs.

are you sure about this? if this is true, why do so many people have trouble doing this? Headers and such need to be rewritten, and so do offsets (in the case with mpg2)....

Even so most players cope with concatenated streams just fine. And if you're doing it to make a VCD you could just have vcdimager or whatever tool you use update the stream, it's always worked for me with VCDs and SVCDs.

Luckily I also have mpgtx, mencoder, transcode and many other great cli video processing tools to fix these things.
