AVCHD, Advanced Video Codec High Definition (AVCHD), is a file-based format for digitally recording and playing back high-definition video. It's MPEG-4 AVC/H.264 and Dolby AC-3 bundled into a MPEG transport stream with limitations tailored to camcorders. The file extension commonly ends in .mts, but if you move the file to another device, the file extension will turn to .m2ts. Both file extensions are used for multiplex audio, video, and other high-definition streams, but .m2ts files usually are played on Blu-ray disk.

The AVCHD format can compress movies into compact disc areas while keeping the video's quality and features intact. AVCHD is Blu-ray compatible, so you may burn its movies straight to DVDs and Blu-ray discs without needing to convert them first.

Below are some of the common reasons why you cannot open AVCHD on your computer:

  • You don't have supported software installed on your computer
  • Your AVCHD file is corrupted while transferring from the camcorder
  • Your portable devices can't recognize AVCHD formats
