AVCHDs

AVCHD, which stands for Advanced Video Coding High Definition, is a file-based digital video recording and playback format that was developed jointly by Sony and Panasonic. Introduced in 2006, it was designed to support high-definition video recording on consumer camcorders. AVCHD utilizes the MPEG-4 AVC/H.264 video compression standard and the Dolby Digital (AC-3) audio compression standard. This combination allows for efficient storage of high-quality video and audio data.

The AVCHD format is characterized by its ability to record video at various high-definition resolutions, including 720p and 1080i, and later 1080p. It is typically stored on media such as memory cards (SD, SDHC, SDXC) or internal hard drives. The file structure commonly includes a BDMV folder, which contains the video files organized in a manner similar to Blu-ray discs. This structure allows for easy playback on compatible devices.

While AVCHD was widely adopted by many camcorder manufacturers, its popularity has seen a decline with the rise of newer, more versatile formats and the increasing capabilities of smartphones and other recording devices. However, AVCHD files are still encountered and require compatible software or hardware for playback and editing. Many video editing applications and media players support AVCHD, but direct editing of the .MTS or .M2TS files can sometimes be challenging due to the complex nature of the codec and container.
