AVCHD (Advanced High Definition Video Coding)

AVCHD (Advanced High Definition Video Coding) is a file-based format for high definition video digital recording and playback. It is packaged into the MPEG transport stream with H.264 and Dolby AC-3, with a set of constraints designed around the camcorders.  The format was developed jointly by Sony and Panasonic and was introduced primarily for use in high definition consumer camcorders in 2006. Related specifications include the AVCCAM and NXCAM Professional variants. Favorable similarities between AVCHD and HDV and XDCAM EX solidified AVCHD 's reputation as a format suitable to professional use. In Spring 2007 both Panasonic and Sony launched their first commercial AVCHD camcorders. In 2008, Panasonic launched the first AVCHD camcorder targeted at the professional market, but it was nothing more than the FLASH card consumer model (which was then discontinued) rebadged with another model number.  The AVCHD specification was updated in 2011 to include the 1080-line 50-frame / ...

Overview

AVCHD uses the H.264 / MPEG-4 AVC format for video encoding, allowing a number of normal, high definition, and stereoscopic (3D) video resolutions. This supports both Dolby AC-3 (Dolby Digital) and uncomprimed linear PCM audio for audio compression. Both Stereo and Surround Multichannel (5.1) are provided. In addition to captured audio and video, AVCHD provides several user-friendly features to enhance media presentation: menu navigation, quick slide shows and subtitles; The menu navigation scheme is similar to DVD-video, allowing access from a standard intro screen to the individual videos. Slide shows are prepared from a sequence of AVC still frames, and a background audio track may accompany them. In some camcorders subtitles are used to time stamp the recordings.  Audio, video, subtitles, and ancillary streams are multiplexed into an MPEG transmission stream and stored as binary files on the media. Usually the FAT file system is used by memory cards and HDDs, while UDF or ISO 9...

Video formats

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 en...

Audio formats

 Most AVCHD camcorders record audio using a compression scheme called Dolby Digital (AC-3). It supports both stereo and multichannel audio. The audio data rate can be between 64 kbit / s and 640 kbit/s. In reality it has reported data levels of 256 kbit / s and 384 kbit / s.[Original research? ]  Some of the professional models allow uncompressed linear PCM audio recording.

Media

AVCHD specification allows the use as recording media of recordable DVDs, memory cards, non-removable solid-state memory, and hard disk drives.  DVD Update  The recordable DVD was the only storage medium when the AVCHD format was first announced.[2] In order to minimize camcorder size, manufacturers opted for an 8 cm disk, also called miniDVD. The recording capacity of an 8 cm disk ranges from 1.4 GB for a single layer single layer disk to 5.2 GB for a double layer double layer disk. Pros: Pros  Most consumers are familiar with DVDs, and therefore considered user friendly.  Recordable DVDs are relatively inexpensive.  For most Blu-ray Disc players stored discs can be played back.  Disks may be used to store stored video for long periods.  Cons: Counterparts  Some argue that recordable DVDs may have a shorter longevity than expected.  Rewritable DVDs cost more than cds writable once.  To play back on set-top players DVDs must be "finalize...

Branding

Panasonic and Sony developed many brand names as well as simplified versions of AVCHD for their professional.  AVCHD Lite Edition  AVCHD Lite is an AVCHD format subset that was released in January 2009 and is limited to 720p60, 720p50 and 720p24 and does not use Multiview Video Coding. AVCHD Lite cameras repeat each 25fps/30fps video frame acquired by camera sensor, delivering 720p50/720p60 bitstream compatible with the requirements of AVCHD and Blu-ray Disc.

AVCHD as file format

A DVD disk stored on it with AVCHD high definition video is often called an AVCHD disk.  AVCHD discs can't be viewed on a standard DVD player, but can be viewed on certain Blu-ray Disc sets.  The AVCHD specification does not officially support Blu-ray Disc media, although some software packages require Blu-ray Disks to author AVCHD content.  AVCHD video can be written on Blu-ray Disk media as Blu-ray Disc video for greater compatibility with Blu-ray disk collections.  The resulting disc works in every Blu-ray Disc set, even some that don't support AVCHD directly. Many providers of tech support Mastering AVCHD. While AVCHD shares several format similarities with Blu-ray Disc, this is not part of the specification for Blu-ray Disk.  Blu-ray disk players with a "AVCHD" label play AVCHD discs recorded on DVDs of either 8 cm or 12 cm. Teams without such a badge are not assured of playing AVCHD cds.
