AVC-Intra Codec LSI

Exclusive P2HD High Image Quality: 10 bit, 4:2:2, AVC-Intra 100 Codec

Full-Pixel, Full-Sample AVC-Intra Recording

These are the first handheld camera-

recorders to support the AVC-Intra codecs of the P2HD Series for HD

recording of broadcast and movie images. Featuring a high compression ratio based on the new MPEG-4 AVC/ H.264 moving picture compression technology, this advanced system maintains intra-frame compression to provide both high image quality and excellent editing performance.

It offers recording and playback of

both AVC-Intra 100 and AVC-Intra 50 modes, and also supports DVCPRO HD recording and playback.

•AVC-Intra 100: 1920 x 1080,* 10 bit, 4:2:2

High-quality images with full-pixel HD and full sampling are recorded at the same bit rate as DVCPRO HD, bringing agile mobility to high-end production.

•AVC-Intra 50: 1440 x 1080,* 10 bit, 4:2:0

Image quality is the same level as DVCPRO HD, but with the SD (DVCPRO

50)bit rate. You get twice the recording time of DVCPRO HD, and about half the required data transmission time.

* These figures are for 1080i/p mode. The AG-HPX255/HPX250 also supports 720p mode.

Multi-Format Recording with Native 24p/25p Support and More

•Native recording modes: In addition to 1080/59.94i with the AVC-Intra codec, native recording is supported at 1080/23.98p or 1080/29.97p and 1080/25p. In 720p, native recording is possible for both DVCPRO HD and AVC-Intra, making it possible to extend recording time by 2 to 2.5 times in comparison with pull-down recording.

*Camera through output and playback image output are pulled-down 59.94 (50) frames.

•Pulldown record mode: This VariCam-compatible mode records*1 with the DVCPRO HD codec. A 2:3 pulldown is applied to 23.98p, and a 2:2 pulldown is applied to 29.97p, to record 1080/59.94i or 720/59.94p and 1080/25p over 50i or 720/25p over 50p. The 23.98pA (2:3:3:2 advanced pulldown) mode is also supported, allowing editing on applicable nonlinear systems*2 with little image degradation.

•59.94Hz/50Hz selector: Supports worldwide HD/SD production.

•SD image acquisition: The DVCPRO 50/DVCPRO/DV multi-codec enables 480/576 image acquisition, with aspect ratio conversion. Select from Side Crop, Letter Box and Squeeze modes.

*1: Not compatible with the AVC-Intra codecs.

High Quality/16 bit, Four Channel Digital Audio

The AG-HPX255/HPX250 can record high quality/16 bit digital audio on all four channels. You can freely select the audio source for each channel, choosing from built-in mic, external mic and line-in. Level volume is also supported on all four channels.

P2 Card Recording Boasts High Reliability and Easy Operation

Double Slot System with Two P2 Card Slots

In addition to allowing continuous recording onto two P2 cards, this system offers the following functions.

•Card select: The recording slot can be switched in Standby mode.

•Hot-swap recording: The card in the standby slot can be exchanged while the other card is being recorded on.

P2 Card Recording Offers High Reliability and a Proven Record for Broadcasting

The P2 card was originally developed for broadcast use. In addition to its large 64 GB* capacity, it strongly resists impacts, vibration and temperature changes, and withstands repeated recording and initialization cycles for extended recording use. The card connector section is designed specifically for professional use, resulting in extremely high durability for insertion and removal. The P2 card and P2HD Series are widely used in broadcast and movie production studios and have a proven track record for reliability, durability and easy operation.

*Total card capacity includes space for data management such as system data; therefore, the actual usable area is less than the capacity indicated on the card.

Versatile MXF File-Based Recording

File-based recording onto memory cards enables high-speed starts, recording starts with no need for cueing, and protection against accidental data overwriting. The recorded data is organized into MXF files. The files can be transferred to a nonlinear editor or over a network without the need for digitizing.*

*PCs must be installed with the included P2 driver in order to mount P2 cards. For editing, PCs must be installed with P2-compatible editing software available from various companies. Read "Notes Regarding the Handling of P2 Files Using a PC" on the back page.
