Looking for simple video joiner software
 

I am looking for a simple video joiner software that does not need to convert the files to join them and which joins with no quality loss. Any recommentations?

I've been using Video Charge for that task.

Try AviDemux http://fixounet.free.fr/avidemux/

Its a paid product but the joiner at http://www.boilsoft.com/ works great for me.

Any of those does that on batch?
I mean I will select 1 video file which should be added to the end of every video in a folder

boilsoft is good, and cheap, give you option to re encode or just direct
