AVC-Intra Codec

High-quality 1920 x 1080 pixel, 10 bit, 4:2:2 HD recording

Comes Equipped with AVC-Intra Codec

An AVC-Intra codec board is included

as standard equipment.

It allows recording in either of two

modes: AVC-Intra 100, for full-pixel

HD (1920 x 1080 and 1280 x 720)

images, or AVC-Intra 50 for low-bit-

rate, low-cost operation. AVC-Intra is

a new codec that further advances

HD production. It complies with the

MPEG-4 AVC/H.264 international

standard based on advanced image

compression technology, and offers both superb image quality and highly

efficient compression. It uses an intra-frame compression system to bring

important advantages to professional editing.

In the AG-HPX300, a new single-chip digital signal processor is integrated

with the AVC-Intra codec circuit. This is another way the AG-HPX300 cuts

power consumption.

High-Image-Quality AVC-Intra 100 Mode

With the same bit rate as DVCPRO HD, this mode supports full 10 bit

recordings with 1920 x 1080 pixels. It enables the AG-HPX300 to capture

master-quality video for high-end video production.

Low-Bit-Rate AVC-Intra 50 Mode

This mode delivers video quality very similar to DVCPRO HD, yet is able to

do so at bit rates usually associated with standard definition (e.g., DVCPRO

50). AVC-Intra 50's lower bit rate doubles the recording time per P2 card

over DVCPRO HD and lowers storage requirements for editing.

HD Multi-Format Capability, Including Native 24p

The AVC-Intra 100 and 50 codecs let you record in a choice of HD video

formats: 1080/23.98p or 29.97p as well as 1080/59.94i. These HD formats

bring extra flexibility to all of your production needs. The AG-HPX300 also

supports 720p recording for HD image production in a variety of formats,

including 60p, 24p and 30p.
