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.

The solution has been designed to ingest all the broadcasters input formats such as Panasonic P2, Sony XDCAM, Canon and GoPro, transcoding them into AVC-Intra 100 format - the standard HD format at HR - and transfers the assets into the production environment.
Melvin Saldanha: It is advisable to keep the video data in the highest quality bit rate and resolution -- DNxHD or AVC-Intra 100.
