Joining videos seems to be an easy task, but you still need the proper tool to do it. And Open Video Joiner is one of them.
This simple application lets you join several videos into one single clip. It supports many source formats (MPG, AVI, WMV, ASF and more) though once they're joined they will all be automatically converted to AVI.
The best thing about Open Video Joiner is its simplicity of use. The program features a really basic interface where you only need to choose your videos and press the "Join" button. But that's not all: the program also features a wide selection of transition effects to insert between videos, and a built-in video preview to see how everything looks.
We could say Open Video Joiner is a really handy app that does its job, and does it well – despite the AVI-only target format...but seriously, that interface needs some improvement.
With Open Video Joiner you can join as many videos as you want in a single AVI file, with transition effects between them.
