AVCHD is a video codec designed for recording high definition videos in 720p, 1080i and 1080p modes on such rewritable discs as Blu-Ray and AVCHD, hard disks and memory cards. The AVCHD standard implies using of AVC video compression format, AC3 audio codec and MTS or M2TS file extension. The main feature of the codec is high compression efficiency together with high image quality. But here comes the main flaw – the codec is really heavy for playback.

MOV is a format developed by Apple and used for movie and other video data storage. It is compatible both with Windows and Mac. However, Windows Media Player can open only early versions of the file extension. If you have versions 2.0 and higher, you need Apple QuickTime Player or you can convert it to other format compatible with your player.
