Panasonic released the first AVCHD camcorder aimed at the professional market in 2008, though it was nothing more than the (by then discontinued) card consumer model rebadged with a different model number. In 2011 the AVCHD specification was amended to include 1080-line 50-frame/s and 60-frame/s modes (AVCHD Progressive) and stereoscopic video (AVCHD 3D).

The new video modes require double the data rate of previous modes. AVCHD and its logo are trademarks of Sony and Panasonic. File organization on Panasonic and Canon solid-state AVCHD camcorders For video compression, AVCHD uses the standard, supporting a variety of standard, high definition, and stereoscopic (3D) video resolutions. For audio compression, it supports both (Dolby Digital) and uncompressed audio. Stereo and multichannel surround (5.1) are both supported.

Aside from recorded audio and video, AVCHD includes many user-friendly features to improve media presentation: menu navigation, simple slide shows and subtitles. The menu navigation system is similar to DVD-video, allowing access to individual videos from a common intro screen. Slide shows are prepared from a sequence of AVC still frames, and can be accompanied by a background audio track. Subtitles are used in some camcorders to timestamp the recordings.

Audio, video, subtitle, and ancillary streams are into an and stored on media as binary files. Usually, memory cards and HDDs use the file system, while optical discs employ. At the file system level, the structure of AVCHD is derived from the specification, but is not identical to it. In particular, it uses legacy ' file naming convention, while Blu-ray Discs utilize filenames (this may be caused by the fact that FAT implementations utilizing long file names are patented by and are licensed on a per unit sold basis ).

AVCHD is compatible with the format and can be authored without re-encoding on Blu-ray discs or DVDs, though not all Blu-ray Disc players are compatible with AVCHD video authored on DVD media, a format known as AVCHD disc. AVCHD recordings can be transferred to a computer by connecting the camcorder via the connection. Removable media like SDHC and Memory Stick cards or DVDs can be read on a computer directly. Copying files from an AVCHD camcorder or from removable media can be performed faster than from a tape-based camcorder, because the transfer speed is not limited by realtime playback. Just as editing and video once demanded an expensive high-end computer, AVCHD editing software requires powerful machines. Compared to HDV, AVCHD requires 2-4x the processing power for realtime playback, placing a greater burden on the computer's CPU and graphics card. Improvements in computing and graphics processor acceleration bring AVCHD playback to mainstream desktops and laptops.
