AVCHD supports a range of video resolutions and scanning methods which have been expanded further with the specification 's 2011 update. The specification's licensing body defines a range of labels for specific feature-compliant products.
Most AVCHD camcorders only support a few of the AVCHD standard video and audio formats allowed in.
In-between recording
AVCHD supports interlaced video, both as standard definition (AVCHD-SD) and as high definition (AVCHD 1080i). Most AVCHD camcorders have AVCHD 1080i. That is the only recording mode provided for some models.
AVCHD-SD is used in the Panasonic HDC-MDH1 shoulder mount, as well as on its North American cousin AG-AC7. A successor model-the AG-AC8, can be recorded in AVCHD-SD mode, too. Some JVC models including the GZ-HM650, GZ-HM670 and GZ-HM690 consumer camcorders as well as the specialist JVC GY-HM70 camcorder can capture AVCHD-SD footage. AVCHD-SD is not compatible with consumer DVD players, since it uses AVC video encoding rather than MPEG-2 Part 2. AVCHD-SD can be played without re-encoding on a Blu-ray Disc player.
Originally designed for watching interlaced video on a cathode-ray tube tv set. When rescaled, filmed or viewed on a computer or other progressive scanning system without proper deinterlacing, material captured for interlaced presentation may exhibit combing or ghosting.
Some AVCHD 1080i camcorders can capture progressive video and record it from the television industry, using interlaced stream borrowing techniques. Particularly in some Panasonic (25p Digital Cinema), Canon (PF25, PF30), and Sony camcorders, Progressive segmented frame (PsF) is used. The 2:3 pulldown technique is used for capturing 24-frame / s progressive video on some 60 Hz models of Canon (PF24) and Panasonic (24p Optical Cinema) camcorders. Most editing tools treat progressive video recorded as interlaced within an interlaced stream, though some editing systems and most standalone Blu-ray Disc players are able to recognize the pulldown pattern to recover the original frames using the process known as inverse telecine.
Progressive-scan video
With frame rates of 24 and 60 frames / s for 60 Hz models and 50 frames / s for 50 Hz models, the AVCHD specification had approved 720-line progressive recording mode from the very beginning. Frame rates of 25 frames / s and 30 frames / s are not possible directly in 720p mode, but can be simulated with frame repeating, where each frame is either replicated twice or a special flag in the video stream instructs a decoder to play each frame twice to conform to performance rates of 50 or 60 frames/s. Some of Panasonic's digital compact cameras, such as the DMC-ZS3 / DMC-TZ7, DMC-FT1, DMC-FZ35 / DMC-FZ38, and DMC-ZS-7 / TZ-10 provide 720p video recording with an effective frame rate of 25 or 30 frames / s in AVCHD Lite format.
Native progressive-scan video for 1080-line resolution was only available in 24 frames / s form until the advent of AVCHD Progressive mode. In 2010, Panasonic launched a new lineup of consumer AVCHD camcorders with progressive scanning mode (frame rate depending on region) of 1080-line 50p/60p. Panasonic advised that not all players supporting AVCHD playback could play 1080-line 50p/60p footage. In 2011, as part of a 2.0 addendum, this mode was formally included in the AVCHD specification, and was renamed AVCHD Progressive. This mode uses the same configuration of AVCHD folder and container files for video storage, with a maximum bitrate of 28 Mbps. Sony launched consumer and professional AVCHD models with AVCHD Progressive recording capability in 2011. JVC introduced the GY-HMQ10 model in 2012 which can also capture AVCHD Progressive video.
