What is an AVCHD file?
AVCHD is a camcorder recording format rather than a single file. On the camera's card it is a folder (PRIVATE/AVCHD/BDMV/STREAM) full of .MTS clips. Each clip is H.264 video with AC3 sound.
AVCHD is mainly used for Sony, Panasonic and Canon HD camcorders. It plays on camera software, VLC and some editors.
