AVC-Intra

AVC-Intra

(Advanced Video Coding-Intra) An HD video format in professional Panasonic camcorders that employs the high-level modes of the H.264/AVC standard. Introduced in 2007 for electronic news gathering (ENG), AVC-Intra uses intraframe coding for high-quality editing in contrast to AVCHD, an H.264 interframe format (see AVCHD and interframe coding).

AVC-Intra records 720p, 1080i and 1080p resolutions with greater accuracy by using 10 bits per pixel for compression. Bit rates are 50 and 100 Mbps. AVC-Intra 50 scales horizontal resolution from 1920 to 1440 pixels and from 1280 to 960 and uses 4:2:0 color sampling. AVC-Intra 100 improves colors with 4:2:2.

AVC-Ultra
In 2012, Panasonic debuted its highest-quality video format. AVC-Ultra includes 4:4:4 color sampling, 12-bit pixel compression and 440 Mbps. It also offers a 25 Mbps "Proxy AV" mode for fast previewing. See H.264, HD formats, 10-bit pixel compression and chroma subsampling.

These are now extended to include support for ALEXA 65 RAW, AJA Cion RAW, as well as Panasonic Varicam 35's AVC-Intra 4K444, 4K422 and 4K-LT compressed RAW formats.
In addition to the company's DVCPRO HD standards that have already been adopted as the video recording format, the adoption of the file-based work flow using the high quality AVC-Intra standards has been decided.
Featuring recording to SD/SDHC cards in AVCHD at up to 24Mbps (AC160), in full 4:2:2 quality to P2 cards, in either DVCPro HD or AVC-INTRA at up to 100Mbps (HPX250) - both with full LPCM-quality sound - these cameras set a new benchmark in both quality and performance.
Other new Flow features include support for AVC-Intra (SDI and file ingest), support for ProRes in Flow Scan, full metadata support for NLEs comprising clip, sequence and marker metadata, and restoration of content offline clips directly from a sequence.

PROXY RECORDING: Focus FS-P250 Proxy Recorder for Panasonic AG-HPX250 AVC-intra camera with streaming and support for cloud-based proxy workflows
For Panasonic, 3D remains a viable option with the introduction of another 3D camcorder--the AG-3DP1, a 3D twin-lens P2 HD shoulder-mount camcorder with 10-bit, 4:2:2 independent-frame, full 1920x1080 resolution AVC-Intra recording.
FOR-A's proprietary media management system conforms to AVC-Intra codec, enabling the system to ingest a full-spec HD video data (1920x1080 pixels, 10 bit 4:2:2 sampling) captured by Panasonic AJ-HPX3000 P2HD camcorder, and manage as meta data, so that searching and previewing of captured video data is possible with a terminal workstation compatible with the AVC-Intra codec.
The Focus FS-P250 is a perfect companion recorder for the AG-HPX250 camera as it enables collaborative cloud-based workflows for AVC-Intra mobile acquisition.
