- Description
- AVCHD (Advanced Video Coding High Definition) is a file format designed for recording and playing back high definition video. It is commonly used in digital camcorders and cameras for capturing HD footage. AVCHD leverages the MPEG-4 AVC/H.264 video compression codec, which efficiently reduces file sizes while preserving high-quality video resolution, and supports both Dolby AC-3 and linear PCM audio codecs for high-quality sound.
- M4R is an iTunes ringtone file that stores mono channel audio. They are identical to the M4A format files only that they are correctly used for ringtones.
