1080p In the consumer market, 60 Hz variants of some Canon, Panasonic and Sony models are capable of recording native 1080p24 video. In the professional and prosumer markets, AVCHD camcorders such as the Panasonic AG-HMC150, the Panasonic AG-HMC40, the Sony HDR-AX2000 and the Sony HXR-NX5U, are capable of recording in all three high definition formats: 1080i, 1080p and 720p. Sony camcorders do not support film-like frame rates — 24p, 25p, 30p — in 720p mode. In 2010, Panasonic introduced a new lineup of consumer AVCHD camcorders with 1080-line 50p/60p progressive-scan mode (frame rate depending on region).[19] While this mode is not compliant with current AVCHD specification, it uses the same compression schemes for video and audio, the same container files and the same folder structure as AVCHD-compliant recordings.[20] Panasonic advised that not all players that support AVCHD playback could play 1080-line 50p/60p video.[21]

In 2011 Sony introduced consumer and professional AVCHD models also capable of 1080-line 50p/60p video recording. Like Panasonic, Sony uses AVCHD folder structure and container files for storing video, with the same maximum bitrate of 28 Mbit/s. Panasonic models have no special marks for progressive-scan capability. Canon models, capable of native 24p recording, have a prominent 24p Native Progressive mark.[22] Sony models capable of 50p/60p recording or of 24p recording are also identified with appropriate marks.
Branding Panasonic and Sony developed several brand names for their professional as well as simplified versions of AVCHD.
AVCHD Lite AVCHD Lite identifies a subset of AVCHD format, in which HD-recording is limited to 720p/30.[23] The 720p/30 video is recorded in the AVCHD 720p/60 format by storing every other frame, and using a bitstream flag to tell the playback device to play each frame twice. Announced in January 2009, the Panasonic DMC-ZS3/DMC-FT1/DMC-TZ7 digital cameras were the first digital cameras to offer AVCHD-lite movie mode. Since then, Panasonic has added AVCHD-lite to more of its digital cameras, such as the Lumix GF1 Micro Four Thirds, Panasonic Lumix DMC-G2, Lumix DMC-FZ35/38, Lumix DMC-TZ10/ZS7, Panasonic Lumix DMC-FX75, Panasonic LX5, LEICA D-LUX 5, LEICA V-LUX 2.
AVCCAM AVCCAM is the name of the professional AVCHD camcorder product line from Panasonic's Broadcast division, and is a marketing brand for "AVCHD with professional features."[24] These professional features include 1/4-inch progressive 3CCD sensor, XLR microphone input, variable-rate overcranking (up to 2.5x at 1080p24), uncompressed PCM audio, solid-state media, and recording at AVCHD's maximum bitrate (24Mbps.) The aforementioned features are not exclusive to AVCCAM. For example, 3CMOS is available in Panasonic's high-end consumer camcorders, while 24Mbps is widely available from rival manufacturers (Canon, JVC, and Sony.)
