When you record video footage on an AVCHD digital camcorder, the captured footage appears as an MTS video file, a format most media players and video-editing programs don't recognize.

To edit and upload the AVCHD (MTS/M2TS) files on Mac, changing it to M4V would be a good idea as M4V is a standard file format for videos for iPods and PlayStation Portables developed by Apple. It is based on the MPEG-4 AVC video codec, and it is also used by QuickTime.
