What is XAVC/XAVC S?
XAVC is a recording format that was introduced by Sony on October 30, 2012. XAVC is a format that will be licensed to companies that want to make XAVC products. XAVC uses level 5.2 of H.264/MPEG-4 AVC which is the highest level supported by that video standard.XAVC can support 4K resolution (4096 × 2160 and 3840 × 2160) at up to 60 frames per second (fps). XAVC supports color depths of 8-bits, 10-bits, and 12-bits.Chroma subsampling can be 4:2:0, 4:2:2, or 4:4:4. The Material Exchange Format (MXF) can be used for the digital container format. XAVC allows for a wide range of content production including intra frame recording and long group of pictures (GOP) recording.
On April 7, 2013, Sony announced that it had expanded XAVC to the consumer market with the release of XAVC S. XAVC S supports resolutions up to 3840 × 2160, uses MP4 as the container format, and uses either AAC or LPCM for the audio. As example used in the Sony FDR-AX100 4K Ultra HD consumer camcorder and Sony HDR-AS100V action camera.
Sony XAVC/XAVC S Camcorders:
Sony has announced that cameras that will support XAVC include two CineAlta cameras which are the Sony PMW-F55 and Sony PMW-F5. Both cameras record XAVC with a color depth of 10-bits and 4:2:2 chroma subsampling. The Sony PMW-F55 can record XAVC with 4K resolution at 60 fps at 300 Mbit/s and 2K resolution at 120 fps at 400 Mbit/s. The Sony PMW-F5 can record XAVC with 2K resolution at 120 fps at 400 Mbit/s.
XAVC can record 4K resolution at 60 fps with 4:2:2 chroma subsampling at 600 Mbit/s. A 128 Gigabyte SxS PRO+ media card can record up to 20 minutes of 4K resolution XAVC video at 60 fps, up to 40 minutes of 4K resolution XAVC video at 30 fps, and up to 120 minutes of 2K resolution XAVC video at 30 fps.
The PXW-Z100 is a 7 lbs handheld camcorder with an integrated 20x 4K-compatible zoom lens. The PXW-Z100 is the first “prosumer” camera that uses Sony’s XAVC recording format. MPEG-4 AVC/H.264 compression is used for HD (1920×1080), QFHD (3840×2160) and 4K (4096×2160) content. Image sampling is 4:2:2 10-bit, with an intra-frame system that compresses each frame individually at a maximum bit rate of 500 Mbit/s or 600 Mbit/s during 4K 50fps or 60fps recording, respectively, and 223 Mbit/s during HD 50fps or 60fps recording.
On November 14, 2012, Sony stated that it might release consumer products that use XAVC.
In March 2014, Sony has launched the consumer video camera, FDR-AX100, which use XAVC S as 4K video specification. It provides maximum resolution of 3840 x 2160, 60Mb/s bit rate. It provides 12X optical zoom, but it is impossible to monitor the image anywhere except the tiny viewfinder while recording.
