P2 Recorder Section AVC-Intra Codec for High-Quality Image and Sound Recording. P2 HD for Superb Reliability. Comes Equipped with an AVC-Intra Codec 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. A single-chip codec LSI is another way the P2 cam has reduced power consumption. •High-Image-Quality AVC-Intra 100: With the same bit rate as DVCPRO HD, this mode supports full 10-bit 4:2:2 recordings with 1920 x 1080 pixels. It brings new mobility to high-end video production. •Low-Bit-Rate AVC-Intra 50: 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). The lower bit rate doubles the recording time per P2 card over DVCPRO HD and lowers storage requirements. It supports 10-bit 4:2:0 recordings with 1440 x 1080 pixels. High-Quality 24-Bit 4-Channel Audio Recording The AVC-Intra mode supports 24-bit digital audio recording* (16-bit for DVCPRO HD, DVCPRO and DV). The AJ-HPX3100 offers 4-channel audio in all recording modes. Each channel input can be selected from FRONT (mic), REAR (line) and WL (wireless). The level volume also supports 4 channels. * The audio signal can be played back by using 24 bit digital audio equipment. For details, refer to "Note Regarding 24 bit Audio" on page 10. 5 The P2 Card: Reliable, Reusable and with Extended Recording Time P2 cards feature a large capacity of up to 64 GB*1, a compact size, and light weight. In addition to the semiconductor memory's inherent resistance to impact, vibration and temperature change, the P2 card also offers outstanding reliability. Unlike tapes and discs, it has no rotating or physically contacting parts. It's built to withstand repeated recording and initialization over many years of use. The P2 card connector is specifically designed to stand up to the repeated insertion and removal involved in professional use. *1: 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. Immediate Startup and Better Data Protection When you press the Record button in standby mode, the P2 cam instantly finds a blank area on the P2 card and begins recording. This speedy response shortens downtime when replacing batteries, and greatly cuts down on battery power consumption by letting you turn the power off during standby. P2 cards can even be exchanged with the power off. It can begin recording immediately even when you're using it to preview video. In normal use, there is no chance of accidentally overwriting a recording. Recordings will not be erased unless you intentionally delete a file or initialize the card.
