About AVC-Intra

The Panasonic AVC-Intra format is a form of H.264 compression that uses only intraframe compression (I-frame-only compression) as opposed to the interframe (long-GOP) compression used by formats such as HDV and AVCHD. For more information about interframe and intraframe compression, see About MPEG Compression.

AVC-Intra is recorded on Panasonic P2 cards at either 100 or 50 Mbps. The 100 Mbps format can record full-width HD video (1920 x 1080 and 1280 x 720) with 4:2:2 color sampling. The 50 Mbps format records at 1440 x 1080 or 960 x 720 with 4:2:0 color sampling. Both formats record 10 bits per color sample.

Final Cut Studio includes its own optimized AVC-Intra decoder that allows media recorded in the Panasonic AVC-Intra format to be ingested natively (without transcoding) and played back with real-time effects in the Timeline. An Apple ProRes codec is the default sequence editing format because encoding to AVC-Intra is not supported. Alternatively, you can transcode AVC-Intra footage directly to an Apple ProRes codec during ingest.
