AVC-Intra[1] is a type of video coding developed by Panasonic that is fully compliant with[2] the H.264/MPEG-4 AVC standard and additionally follows the SMPTE RP 2027–2007[3] recommended practice specification. AVC-Intra is available in a number of Panasonic's high definition broadcast products, such as, for example, their P2 card equipped broadcast cameras.[4] It is now also supported in various products made by other companies.

Panasonic announced AVC-Intra codec support in April 2007. The use of AVC-Intra provides production quality HD video at bit rates more normally associated with ENG (Electronic news gathering) applications, permitting full resolution, 10 bit field capture of high quality HD imagery in one piece camera-recorders.

AVC-Intra is intended to serve needs of video professionals who have to store HD digital video on digital storage media for editing and archiving purposes. It defines 10-bit intra-frame only compression, which is easy for editing and preserves maximum video quality. The technology significantly outperforms the older HDV (MPEG2 based) and DVCPRO HD (DV based) formats, allowing the codec in certain conditions to maintain better quality in half the storage space of DVCPRO HD.[citation needed]

Technical details

There are two classes;

  • AVC-Intra 50:
    • nominally 50 Mbit/s, size of each frame is fixed
    • CABAC entropy coding only.
    • 1920 × 1080 formats are High 10 Intra Profile, Level 4
    • 1280 × 720 formats are High 10 Intra Profile, Level 3.2
    • 4:2:0 chrominance sampling
    • frames are horizontally scaled by 3/4 (1920x1080 is scaled to 1440x1080. 1280 × 720 is scaled to 960x720)
  • AVC-Intra 100:
    • nominally 100 Mbit/s, size of each frame is fixed
    • CAVLC entropy coding only.
    • All formats are High 4:2:2 Intra Profile, Level 4.1
    • 4:2:2 chrominance sampling
    • frames are not scaled

Common to both classes;

  • Frame rates: 1920 × 1080 (23.98p / 25p / 29.97p / 50i / 59.94i), 1280 × 720 (23.98p / 25p / 29.97p / 50p / 59.94p)
  • 10 bit luma and chroma

Panasonic implementation[5] of AVC-Intra codec has following limitations: 8 × 8 transform only, 8 × 8 intra prediction only, 10 slices per picture, MBAFF for interlace material, custom quantization matrices for each class and each resolution.

  • AVC-Ultra:

The Panasonic AVC-Ultra family defines an additional three new encoding parameters within the MPEG-4 Part 10 standard, utilizing up to the 4:4:4 Intra Predictive Profile, as well as an additional low bitrate proxy recording mode.

The most efficient new parameter within AVC-Ultra is by Panasonic called, AVC-LongG. AVC-LongG enables compression of video resolutions up to 1920 × 1080 @ 23.97, 25 and 29.97p, with 10 bits of pixel depth at 4:2:2 color sampling, at data rates as low as 25 Mbit / sec.

More over, the AVC-Intra Class 50/100 is now extended to Class 200 and Class 4:4:4. The Class 200 mode extends the bitrate to 226 Mbit / sec for 1080/23,97p, while the Class 4:4:4 extends the possible resolution from 720p to 4K with pixel depths at 10 and 12 bits.

The bitrate settings for Class 4:4:4 varies between 200 and 440 Mbit / sec depending on the resolution, frame rate and bit depth. Both the Class 200 and the Class 4:4:4 are Intra-only coding modes.

The AVC-Proxy mode enables extremely fast ENG content delivery and offline edits of 720p and 1080p video at bitrates varying between 800 Kbit to 3,5 Mbit / sec at 8 bits of pixel depth.

Third Party Support

  • Avid's Media Composer 3.5.0 provides support via Avid Media Access (AMA), a new plug-in architecture[6]
  • Apple's Final Cut Pro 7 provides native AVC-Intra decoding within a ProRes 422 timeline. [citation needed]
  • MXF4mac offers an AVC-Intra codec for QuickTime that allows to export AVC-Intra and to set up native AVC-Intra timelines in Final Cut Pro.[7]
  • EVS Broadcast Equipment has announced AVC-Intra 100 support for their XT[2]+, XT[3] and XS server family[8]
  • MainConcept offer an AVC-Intra encoder and decoder as part of their Codec SDK[9]
  • Harris Corporation announced AVC-Intra support for the NEXIO AMP line of video servers at NAB 2008
  • Omneon Inc has announced AVC-Intra support for their Spectrum and MediaDeck products[10]
  • Quantel demonstrated AVC-Intra workflow at NAB 2007,[11] and released to customers[12] in 2008 with their V4 software.[13]
  • Grass Valley has announced native support for AVC-Intra in Edius 4.5[14]
  • Adobe's After Effects CS5 provides native AVC-Intra decoding.[15]
  • Vanguard Software Solutions provides an H.264/AVC PC SDK capable of encoding at 100 Mbit/s in real-time[16][17]
  • FFmpeg and Libav support decoding of both forms of AVC-Intra[18]
  • ATEME AVC-I Contribution Encoders[19]

Third Party Implementation (IP Cores)

Several companies have introduced AVC Intra codec IP Core to the market.[20]

  • http://www.jointwave.com |Jointwave provides AVC-Intra 50 and AVC-Intra 100 Codec IP.
  • Vanguard Software Solutions provides AVC-Intra 50 and 100 encoder IP (up to AVC-Ultra: 1080p60 at 300 Mbit/s).
  • Nethra Imaging provides AVC-Intra 50 and 100 encoder IP.
