Batch Video Joiner

i'm looking for a program where I could merge or join movies in bulk.

Say I have a "clip 1" which is the beginning titles and I want to join it with about 30 other movie clips named "clip a" "clip b" and so on. So I was wondering is there anything like this, and yes, for free

Basically those files should be made like this "clip 1 + clip a" and the file name should stay as clip a. Any suggestions?

I couldn't completely understand your query, but I believe you can merge and render your videos with editing softwares like sony vegas. A search on YT with correct keywords will help you. Cheers.

You should have a look at ffmpeg:
http://ffmpeg.org/

It's a command line tool (it might take some time to understand how it works if you're not familiar with such ones) but it is pretty damn powerful.
If all videos are of the same file type, have the same resolution & same framerate you can even merge them without re-encoding the video which will be super fast.
