AVCHD (Advanced Video Coding High Definition)[1] is a file-based format for the digital recording and playback of high-definition video.
Developed jointly by Sony and Panasonic, the format was introduced in 2006 primarily for use in high definition consumer camcorders.[2] Favorable comparisons of AVCHD against HDV and XDCAM EX[3][4] solidified perception of AVCHD as a format acceptable for professional usage. Panasonic released the first professional AVCHD camcorder in autumn of 2008, followed by Sony in the first quarter of 2010.
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 modes also allowed higher system data rate than existing modes.
AVCHD and its logo are trademarks of Panasonic and Sony.[5]
File organization on Panasonic and Canon solid-state AVCHD camcorders
For video compression, AVCHD uses the MPEG-4 AVC/H.264 (AVC) standard, supporting a variety of standard, high definition, and stereoscopic (3D) video resolutions. For audio compression, supports both Dolby AC-3 (Dolby Digital) and uncompressed linear PCM audio. Stereo and multichannel surround (5.1) are both supported.
Aside from recorded audio and video, AVCHD includes features to improve media presentation: menu navigation, 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 multiplexed into an MPEG transport stream and stored on media as binary files. Usually, memory cards and HDDs use the FAT file system, while optical discs employ UDF or ISO9660.
At the file system level, the structure of AVCHD is derived from the Blu-ray Disc specification, but is not identical to it. In particular, it uses legacy "8.3" file naming convention, while Blu-ray Discs utilize long filenames (this may be caused by the fact that FAT implementations utilizing long file names are patented by Microsoft and are licensed on a per unit sold basis[6]). Another difference is location of the BDMV directory, which contains media files. On a DVD-based camcorder the BDMV directory is placed at the root level, as on the Blu-ray Disc. On the HDD-based Canon HG10 camcorder the BDMV directory is located in the AVCHD directory, which is placed at the root level.[7] Solid-state Panasonic and Canon camcorders nest the AVCHD directory inside the PRIVATE directory.[8] Following a standard agreed upon by many still camera manufacturers, solid-state camcorders have a root-level DCIM directory for still images.[9]
AVCHD has been designed to be compatible with Blu-ray Disc format[2] 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 USB 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 DVCPRO HD and HDV 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 multi-core computing and graphics processor acceleration bring AVCHD playback to mainstream desktops and laptops.
AVCHD supports a variety of video resolutions and scanning methods, which has been further extended with the 2011 amendment of the specification. The licensing body of the specification defines a variety of labels for products compliant with specific features.
Most AVCHD camcorders support only a handful of the video and audio formats allowed in the AVCHD standard.
AVCHD supports both standard definition (AVCHD-SD) and high definition (AVCHD 1080i) interlaced video.
AVCHD 1080i is available on most AVCHD camcorders. For some models this is the only recording mode offered. AVCHD-SD is used in the shoulder-mount Panasonic HDC-MDH1, available on Southern-Asian markets,[10] as well as on its North American AG-AC7 cousin. Several new models from JVC like the GZ-HM650, GZ-HM670 and GZ-HM690 can record AVCHD-SD video too. AVCHD-SD is not compatible with consumer DVD players, because it employs AVC video encoding instead of MPEG-2 Part 2. AVCHD-SD can be played on a Blu-ray Disc player.
Interlaced video had been originally designed for watching on a cathode-ray tube television set. Material recorded for interlaced presentation may exhibit combing or ghosting when it is rescaled, filmed out or watched on a computer or another progressive-scan device without proper deinterlacing.
Some AVCHD 1080i camcorders can capture progressive video and record it within interlaced stream borrowing techniques from television industry. In particular, Progressive segmented frame (PsF) is utilized in some Panasonic (25p Digital Cinema), Canon (PF25, PF30) and Sony camcorders. The 2:3 pulldown technique is used in some 60 Hz versions of Canon (PF24) and Panasonic (24p Digital Cinema) camcorders for recording 24-frame/s progressive video. Most editing tools treat progressive video recorded within an interlaced stream as interlaced, though some editing systems and most standalone Blu-ray Disc players are capable of recognizing the pulldown pattern to recover the original frames using the process known as inverse telecine.
Since the very beginning the AVCHD specification had supported 720-line progressive recording mode at frame rates of 24 and 60 frames/s for 60 Hz models and 50 frames/s for 50 Hz models. Frame rates of 25 frames/s and 30 frames/s are not directly available in 720p mode, but can be simulated with frame repeating, when every frame is either repeated twice or a special flag in the video stream instructs a decoder to play every frame twice to adhere to output rate of 50 or 60 frames/s.
Many of the digital compact cameras made by Panasonic, such as the DMC-ZS3/DMC-TZ7, DMC-FT1, DMC-FZ35/DMC-FZ38, and DMC-ZS-7/TZ-10 offer 720p video recording with effective frame rate of 25 or 30 frames/s in a format called AVCHD Lite (see below).
Until the advent of AVCHD Progressive mode, native progressive-scan video for 1080-line resolution had been available only in 24 frames/s variant. In 2010, Panasonic introduced a new lineup of consumer AVCHD camcorders with 1080-line 50p/60p progressive-scan mode (frame rate depending on region).[11] Panasonic advised that not all players that support AVCHD playback could play 1080-line 50p/60p video.[12] In 2011, this mode was officially included into the AVCHD specification as part of 2.0 addendum, and has been called AVCHD Progressive. This mode uses the same AVCHD folder structure and container files for storing video, with the maximum bitrate of 28 Mbit/s. In 2011, Sony introduced consumer and professional AVCHD models capable of AVCHD Progressive recording. In 2012 JVC announced the GY-HMQ10 model, which also can record AVCHD Progressive video.
Most AVCHD camcorders record audio using Dolby Digital (AC-3) compression scheme. Stereo and multichannel audio is supported. Audio data rate can range from 64 kbit/s to 640 kbit/s. In practice, data rates of 256 kbit/s and 384 kbit/s have been observed.[original research?]
Some professional models allow recording uncompressed linear PCM audio.
AVCHD specification allows using recordable DVDs, memory cards, non-removable solid-state memory and hard disk drives as recording media.
Conventional 12 cm disc (left) compared to 8 cm disc (right)
When the AVCHD standard was first announced, recordable DVD was the only recording medium.[2] To reduce camcorder size, manufacturers opted for a 8 cm disc, sometimes called miniDVD. Recording capacity of a 8 cm disc ranges from 1.4 GB for a single-sided single layer disc to 5.2 GB for a double-sided double layer disc.
Pros:
- DVDs are familiar to most consumers, thus considered user-friendly.
- Recordable DVDs are relatively cheap.
- Recorded disc can be played back in most Blu-ray Disc players.
- Discs can be used for long-term storage of recorded video.
Cons:
- The longevity of recordable DVDs is argued to be much shorter than expected.[13]
- Rewritable DVDs cost more than write-once discs.
- DVDs have to be "finalized" to be played back on set-top players (though DVD-RWs can be unfinalized again).
- Double-layer recording is less robust than single-layer recording.
- To use both sides of a double-sided disc it must be flipped over, because camcorders have pickup from one side only.[citation needed]
- AVCHD DVDs cannot be played back on regular DVD players.
- The AVCHD specification limits data rate for DVD-based AVCHD camcorders to 18 Mbit/s, but no DVD-based AVCHD camcorder manufactured to date is capable of recording at data rate higher than 12 Mbit/s (Canon, Sony) or 13 Mbit/s (Panasonic).
- A single-sided single-layer 8 cm DVD can fit only 15 minutes of video at 12 Mbit/s, 14 minutes at 13 Mbit/s.
- DVD pickup mechanism is very susceptible to vibration.
- 8 cm DVDs cannot be used in many slot-loading drives and may even damage the drive.
As capacity of memory cards grew while their price dropped, DVDs quickly fell out of favor. No DVD-based AVCHD camcorders have been produced since 2008.
While DVDs are no longer used for acquisition, they are becoming popular as distribution media. Many authoring programs offer "AVCHD" profile for recording high definition video on a DVD. Such AVCHD discs are incompatible with regular DVD-Video players, but can be played in many Blu-ray Disc players. A conventional single-layer 12 cm DVD can store 35 minutes of video recorded at maximum bitrate allowed for DVD media by AVCHD specification - 18 Mbit/s.
Canon HG10 HDD-based AVCHD camcorder
A hard disk drive was added as an optional recording medium to AVCHD specification shortly after the new video standard had been announced.[14] Presently, capacity of built-in HDDs ranges from 30 GB to 240 GB.
Pros:
- Higher capacity than other media types, which allows for longer continuous recording.
Cons:
- Sensitive to atmospheric pressure. The HDD may fail if the camcorder is used at altitudes above 3,000 metres (9,800 ft).
- Vulnerable to mechanical shock or fast movement.
- All HDD-based AVCHD camcorders employ non-removable disks. To transfer video to a computer the camcorder must be connected with a USB cable. Most camcorders require using an AC power adapter for this operation.
- The sound of moving magnetic heads may be heard in the recorded video when recording in quiet environment.
- Replacing a damaged HDD requires disassembling a camcorder and cannot be done by a consumer.
Canon HF100 camcorder with a partially inserted Secure Digital card
Many AVCHD camcorders employ Secure Digital or "Memory Stick" memory cards as removable recording media. Solid-state memory cards offer rewritable storage in a compact form factor with no moving parts. With transfer speeds ranging from 10 MByte/s to 25 Mbyte/s for most brands[15][16], it takes about 1 minute to transfer 1 GB of video from a card to a computer for viewing and/or editing.
Panasonic and Sony chose removable flash memory as the sole type of recording media in their professional AVCHD lineups, AVCCAM and NXCAM respectively.
Until 2010 Sony insisted on usage of its own memory card format - Memory Stick. Starting from 2010 Sony allowed using both Memory Stick as well as Secure Digital cards in its consumer and professional camcorders. Panasonic as well as other manufacturers of AVCHD camcorders use Secure Digital cards as removable flash media. Most models accept Secure Digital High Capacity cards (SDHC), while some models are also compatible with Secure Digital Extended Capacity (SDXC) cards, which offer higher transfer speed and capacity.
Pros:
- Compact and lightweight.
- Does not require time for spin-up and initialization.
- Not vulnerable to magnetic fields.
- Can withstand a wider range of air pressure, humidity and vibration than HDDs.
- Can be easily backed up to DVD for viewing and for long-term archiving.[8]
- Can store mixed media content, including still images like snapshot photos and still-frame captures.
- The recording section contains no moving parts, thus operation is almost silent; also a camera can be made more compact and less prone to mechanical damage in case of being dropped.
- Most new computers, many TV sets and Blu-ray Disc players, as well as many personal portable media players have built-in card readers and can play AVCHD video directly from a card.
Cons:
- More expensive per minute of recording than a built-in HDD or DVD media.
- Not reliable for long term storage and may wear out more rapidly than expected, especially the cards made with MLC technology as opposed to cards using SLC technology.[17][18]
- Vulnerable to electrical damage, such as static discharge, and too high temperature.
- A bad memory card can cause data corruption, causing loss of one or more clips.
- Loss of data can occur if a card is removed or power is turned off while the card is being recorded to.
- Easy to misplace due to small form factor.
Some AVCHD camcorders come with built-in solid-state memory either as a sole media, or in addition to other media.
Pros:
- Allows making a camcorder smaller if no other media is used.
- Always available for recording, in case other type of media is full or missing.
Cons:
- Because recording media is non-removable, the recorded images should be backed up either to a computer with a USB cable to transfer video or (if the camera accepts them) to another FLASH card or even a DVD or Blu-ray disc through an externally connected burner). Usage of an AC power adapter may be required.
- Non-removable media cannot be shared, sent or stored separately of the camcorder.
- If damaged or worn out, non-removable media cannot easily be replaced like a memory card.
Panasonic and Sony developed several brand names for their professional as well as simplified versions of AVCHD.
AVCHD Lite identifies a subset of AVCHD format, in which progressive-scan video is acquired at 30 frames/s with 720-line resolution.[19] Such a video is recorded in the AVCHD 720p60 stream by using a flag telling a decoder 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.
Formerly known as "AVCHD with professional features,"[20] AVCCAM is the name of professional AVCHD camcorders from Panasonic's Broadcast division. Some of these professional features listed in early Panasonic advertising materials included 1/4-inch progressive 3CCD sensor, XLR microphone input, solid-state media and capability of recording at the maximum AVCHD bitrate - 24 Mbit/s. The aforementioned features are not exclusive to AVCCAM. Moreover, some of these features like CCD sensor technology have been dropped by Panasonic, while 24 Mbit/s recording rate is widely available from rival manufacturers even on consumer models.
NXCAM is the name of Sony's professional video lineup employing the AVCHD format.[21] NXCAM camcorders offers 1080i, 1080p and 720p recording modes. Unlike AVCCAM, NXCAM camcorders do not offer film-like frame rates — 24p, 25p, 30p — in 720p mode. On the other hand, some NXCAM models offer AVCHD Progressive recording mode,[22] while Panasonic abstains from using this mode on its professional cameras.
Recorded AVCHD video can be played back in a variety of ways:
- Direct playback — video can be played on a television set from a camcorder through HDMI or component-video cable.
- AVCHD disc — AVCHD video, recorded onto DVD can be played on most Blu-ray Disc players[8] or on a PlayStation 3 gaming console.
- Blu-ray disc — AVCHD video, recorded onto Blu-ray disc can be played on most Blu-ray Disc players (see table below).
- AVCHD memory card — AVCHD video, recorded on an SDHC or Memory Stick card can be played on select Blu-ray Disc players, HDTV sets, on a PlayStation 3 gaming console and on some other set-top media players.
- USB playback — video files, recorded on an external storage device like a hard disk drive or a USB "stick" can be played on select Blu-ray Disc players, HDTV sets, PlayStation 3 gaming console, set-top media players and from a computer.
- Computer playback — any media and target format that is supported by a particular computer hardware and software can be watched on a computer monitor or TV set. Presently, the open-source VLC media player will play AVCHD video files, as well as a wide variety of additional formats, and is freely available for most modern operating systems (including Linux, Mac OS X, MS Windows) and some mobile platforms. On both Mac OS and MS Windows systems, the default media players from Apple (QuickTime) will not play AVCHD natively. Some Windows 7 editions are able to import and play AVCHD video natively, having files with extensions M2TS, MTS and M2T pre-registered in the system. (Windows 7 starter edition does not support AVCHD files itself, and a third-party player must be installed.) In editions of Windows 7 which do support AVCHD files, Windows Media Player is able to index content of these files, while Windows Explorer is able to create thumbnails for each clip.[23] Windows 7 does not support importing of AVCHD video metadata such as thumbnail images, playlists, and clip index files. Joining AVCHD video files during the import is not supported either.[23]
There is a known incompatibility within the Panasonic brand. The original HD Writer importing and editing software, which was shipped from 2006 to 2008, cannot recognize the current 1080i format or the newer formats like 1080p50 or 1080p60. The newer HD Writer AE can read the newer 1080i format and versions 2 and higher can read 1080p (in both frame rates).
[edit] AVCHD as distribution format
A DVD disc with AVCHD video recorded on it is often called an AVCHD disc.[24][25] AVCHD discs cannot be played in a standard DVD player, but can be played in many Blu-ray Disc players.[2] Smooth playback is not guaranteed if overall data rate exceeds 18 Mbit/s. It is possible to create simple menus similar to menus used for DVD-video discs.
AVCHD content can also be recorded on SDHC cards and played by many television sets, Blu-ray Disc players and media consoles.
AVCHD specification does not officially support Blu-ray Disc media, though some software packages allow authoring AVCHD content on Blu-ray Discs. For better compatibility with Blu-ray Disc players AVCHD video can be authored on Blu-ray Disc media as Blu-ray Disc video. Authoring a Blu-ray Disc video title does not require re-encoding of AVCHD audio and video streams. The resultant disc will play in any Blu-ray Disc player including those that do not explicitly support the AVCHD format.
Many software vendors support AVCHD mastering. In particular:
- Cyberlink PowerProducer can author a compliant AVCHD disc, or BDMV on DVD media.[26]
- Ulead DVD MovieFactory Plus 6 with HD Power Pack can master AVCHD discs with menus.[27]
- Various Sonic products can author AVCHD discs using HD/BD Plug-in.[28][29][30]
- Compressor 3.5 is capable of authoring AVCHD discs; subtitles are not supported.[31][32]
- Nero Vision 9 can create an AVCHD disc with data rate up to 18 Mbit/s, or an AVCHD-compliant folder for distribution on an HDD or a memory card with data rate up to 24 Mbit/s.[33]
- Sony DVD Architect 5 can author AVCHD-compliant discs with menus using AVC encoding as well as non-standard discs using MPEG-2 encoding. In both cases data rate is limited to 18 Mbit/s.
- Panasonic HD Writer AE can author AVCHD content on DVDs, BD discs and on SD cards.[34]
- MultiAVCHD can author AVCHD discs as well as Panasonic-compliant AVCHD memory cards.[35]
- Magix Movie Edit Pro 15 Plus with updates can author AVCHD content on DVDs, BD discs.[36]
- Pinnacle Studio 11.1.2 and higher offers AVCHD disc output.[37]
Blu-ray Disc players with "AVCHD" logo play AVCHD discs authored either on 8 cm or 12 cm DVDs. Players without such a logo are not guaranteed to play AVCHD discs.
Although AVCHD shares many format similarities with Blu-ray Disc, it is not part of the Blu-ray Disc specification. Consequently, AVCHD-playback is not universally supported across Blu-ray Disc players. In addition, new developments such as 1080-line 50p/60p recording mode employed in some camcorders, are not compliant with the current Blu-ray Disc specification.
As the creators of AVCHD, Sony and Panasonic support AVCHD playback in their Blu-ray Disc players. In particular, the Sony BDP-S1, Sony BDP-S300, Sony BD507, the Panasonic DMP-BD10, the Panasonic DMP-BD30K, the Panasonic DMP-BD35, the Panasonic DMP-BD60K, the Panasonic DMP-BD80K, and the PlayStation 3 can play AVCHD discs. In addition, some Panasonic and JVC Blu-ray Disc players (e.g. Panasonic DMP-BD60K, Panasonic DMP-BD80K) support AVCHD playback from SDHC memory cards.
In one instance, AVCHD playback was removed from a Blu-ray Disc player already on the market, the Samsung BD-P1200. Firmware update 2.3 removed AVCHD support from the BD-P1200.[38]

- ffdshow is a free, Open Source collection of codecs, including an AVCHD decoder.
- CoreAVC is an H.264 decoder for Windows, which can decode AVCHD as well as a variety of other H.264 formats.
- Badaboom is a media converter that uses NVIDIA GPUs to accelerate conversion of AVCHD to mobile devices.
- HandBrake will convert AVCHD Lite format to MP4 and MKV (tested on OSX; other versions available), AVI and OGM are supported in versions before 0.9.4.
- Roxio Toast 10 Titanium on Mac OS X will convert AVCHD to most computer formats presently available.
- Total video converter is a converter for most video formats, including converting from AVCHD and burning AVCHD disc.
The following video-editing software features support for the AVCHD format:
- Avid Media Composer (version 5.x and later) supports AVCHD via transcode import. AMA linking is available in Avid Media Composer 6 when a special AMA plugin is downloaded from the Avid download center.
- Adobe Premiere Pro (from version CS4 onwards).
-
- Elemental Accelerator is a third party plug-in for Adobe Premiere Pro CS4 that converts AVCHD to various H.264 or MPEG-2 formats.
- Adobe Premiere Elements (version 7 through 9 only support import, no AVCHD output), version 10 supports AVCHD output.
- Apple's Final Cut Pro X natively supports AVCHD through Import From Camera.
- Apple's Final Cut Pro for Mac OS X. The latest version of Final Cut Pro 7 claims better integration with Apple's other professional applications and improved codec support for editing HD, DV and SD video formats, including encoding presets for devices such as iPod, Apple TV, and Blu-ray Discs.
- Apple's Final Cut Express 4, Final Cut Pro 6.0.1, and iMovie '08-'09 (iMovie is bundled with all new Apple computers; Final Cut Express and Pro are sold separately) do not support editing of AVCHD clips directly. Imported AVCHD clips are automatically converted into the Apple Intermediate Codec format, which requires more hard disk space (40GB per hour as opposed to 13.5GB per hour for Standard Definition DV), a more powerful machine (an Intel-based Mac), and a more recent OS (Mac OS X 10.5). Final Cut Pro 6.0.5 "logs and transfers" the footage from AVCHD to AppleProRes by default and also gives the option of converting to the Apple Intermediate Codec. It does not allow native transferring of the *.m2ts clips nor directly editing them. The latest release of Apple's iLife suite (specifically, iMovie) has added support for AVCHD Lite cameras and camcorders.[74][75] It automatically imports AVCHD files when attaching a supported camera to the computer, and it can import older MTS or M2TS files that have been rewrapped (see above) e.g. as m4v.
- AVS Video Editor supports videos from HD-cameras(HD Video (inc. AVCHD, MPEG-2 HD and WMV HD), TOD, MOD, M2TS.) Burn AVCHD video to CD-R/RW, DVD+/-R, DVD+/-RW, DVD-RAM, Double/Dual Layer on Windows XP, 2003, Vista, 7 (no Mac OS/Linux support).
- Blender supports the AVCHD format on Windows[citation needed] and Linux systems (using a FFmpeg decoder). Blender has a little-known, very powerful video editing system with infinite layer bit-depth and integration with the 3D editing component. BlenderAVC streamlines the process of importing the files, as it is difficult and bug-prone without AVS scripts. Blender supports proxy editing at down to 25% scaling, which helps when editing AVCHD video, which is slow.
- Corel VideoStudio supports importing, rendering and burning of AVCHD format in Windows system.
- Elecard AVC HD Editor affords reordering, trimming and merging of AVCHD clips without the need for transcoding.
- Cyberlink PowerDirector 7 is capable of editing AVCHD natively, without transcoding, intermediate formats or proxy files. Using a patented technique (SVRT), AVCHD clips can be edited and output losslessly to AVCHD or Blu-ray Disc. PowerDirector also supports GPU encoding acceleration on both ATI and NVidia graphics platforms. PowerDirector can output the finished movie to a variety of video formats, DVD, AVCHD on DVD, or Blu-ray Disc.
- Grass Valley's Edius 5.5 and Edius Neo 2
- Microsoft's Windows Live Movie Maker 2011 (part of the Windows Live Essentials package) converts to lower resolution for editing and playback, but is capable of exporting in HD.
- Dayang's Montage Extreme [ME] 1.2
- Nero Ultra Edition Enhanced (from version 7 onwards) includes the Nero Vision editor and the Nero Showtime player, which both support AVCHD files. NeroVision can author DVDs in the AVCHD format.
- Pinnacle Studio Plus (from version 11 onwards)
- Sony Vegas 7.0e
- Vegas Pro (from version 8 onwards)
- Vegas Movie Studio Platinum (from version 8 onwards)
- Kdenlive for Linux and BSD platforms
- Openshot Video editor for Linux
- Other developers have pledged their support but it may still take some time for the implementation.
The following open source codecs can decode AVCHD files:
- ffdshow tryouts, revision 1971 May 23, 2008, will decode AVC (H.264) format video.[76]
- libavcodec (part of FFmpeg project) is a codec library that supports AVCHD. It is used in Jahshaka and Blender, notably.
