Lofty Video Joiner is a tool to help you join or merge AVI/DivX, XivD, MPEGI/II, VOB, DAT, WMV, or ASF files in one large file in various formats. You can add an unlimited number of video files to the list and rearrange their order if needed, then merge the videos files to a large movie file. You can use it to convert a single file, too. Also, you can change the framerate, size, etc. as you like.
