  • Solution: QuickTime can't playback the files that's stored in the memory card of a camcorder or the AVCHD codec. You'll need to either convert it to an MOV file or install the codec. Alternatively, try moving or copying the files over to your local directory and then right-click to open the files individually rather than the usual double-click.

9. MTS

MTS video format
