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.
