Compatible for mostly all video formats

Free AVI MP4 WMV MPEG Video Joiner has good support for a wide range of video formats like AVI, WMV, MPEG, MP4, 3GP, FLV, SWF, RM, RMVB, VOB, MOV, QT, TS, MKV, etc.

Fact: Say you have several short video clips that you want to merge into a single movie. If these offline videos are in standard Windows Media or AVI formats, you can easily use Windows Movie Maker to join the clips. Just drag the clips onto the timeline and publish a new movie - now consider a more COMPLICATED scenario: you have downloaded a Flash video from YouTube, a 3GP clip from your mobile phone, an MPEG video from your digital camera and an MP4 podcast from your iPod. How to you join these files of various formats into one video?

Details

After you start the video joiner, use the "Add Video..." button at the right top to find & add video files (files of supported formats can be seen in the activated browser window). You can input videos of different formats, even those with different parameters (such as frame size, frame rate, video codec). You are allowed to add as many files as needed without size limit.
