Panasonic P2 Handheld Camcorder Understanding P2 Workflow: Final Cut Pro - Page 3

AVC-Intra or DVCPRO HD? The Advanced Video Codec-Intra frame from Panasonic combines high quality recording in the field with the solid state workflow of P2 media and MXF metadata. AVC / H.264 is a new generation state-of-the art codec family with both Intra and Inter frame compression implementation options (profiles). Developed to provide high image quality, including greater encoding efficiency, AVC-Intra provides production companies and broadcasters more choices without compromising HD quality. At its highest level, AVC-Intra 100 gives professionals access to mastering quality HD recording and does not utilize any video sub-sampling. With 4:2:2, 10-bit Intra-frame coding, in 1080 progressive or interlace systems, AVC-Intra 100 records the full 1920x1080 raster, representative of master-quality recording. In 720 progressive systems, AVC-Intra 100 records the full 1280 x 720 raster, again without any video subsampling. AVC-Intra 50, a fully compliant H.264 codec implementation, offers significantly better compression efficiency than older codec families. The storage and bandwidth savings, without the compromises of long GOP compression, allows AVC-Intra 50 to provide subjectively similar video quality to DVCPRO HD at one half the bit rate. This is a big benefit where bandwidth requirements are limited or longer recording times are needed, such as for ENG applications. Also, by utilizing intra-frame compression with its frame bound compression, AVC-Intra is unaffected by motion or rapid changes in scene content. More important, due to intra-frame compression, AVC-Intra stands up to rigorous editing, including compositing, multiple layers of video, etc., far better than long-GOP compression schemes. All AVC-Intra 720p 23.98p / 25p / 29.97p and 1080p 23.98p / 25p / 29.97p frame rates are native - providing high quality video with associated storage savings. This feature is only available on P2 camcorders, due to the flexibility of the camcorder's solid-state recording to the P2 card, thus, not relying on the consistent rate of a traditional camcorder's tape recording mechanism. AVC-Intra is standard in the Panasonic AJ-HPX3000 2/3" Native 1080p 2.2M P2 HD camcorder, and as an option in the ultra-versatile AJ-HPX2000 2/3" 1.1M P2 HD camcorder and the AJ-HPM110 P2 Mobile Recorder / Player. All of these products support the DVCPRO formats too. Because the AVC-Intra format is P2 based, the workflow is similar to that of DVCPRO on P2. Shoot Prior to recording any data on the P2 cards, each card is erased in the camera. If I plan to use multiple storage volumes, a 3-digit code is assigned to each. Each time a card is placed in the camera, the card number is notated on the P2 log sheet.
