MP4Cam2AVI is a MP4/MOV/M2TS to AVI repackaging tool for digital photo-video cameras, it makes their clips editable in VirtualDub, MovieMaker and other AVI editors. Also it can combine (join) multiple clips from camera into a single AVI movie, preserving audio/video sync.
No video recompression (by default), no quality loss, fast operation (5-20x realtime). No installation needed - just download, unzip and run mp4cam2avi.exe.
You can use Avdshare Video Converter to convert MOV to AVI, MP4, WMV, Apple ProRes, AVCHD, DV, MKV, VOB, RMVB, FLV, WebM, etc.
I highly recommend Avdshare Video Converter to convert MOV to MP4 without output quality loss, and also convert MOV to more video formats, like converting MOV to AVI, to FLV, to MOV, to WMV, to MKV, to ASF, to 3GP, etc.
