Hardware

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 600

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 launched the consumer video camera, FDR-AX100, which uses XAVC S. It provides a maximum resolution of 3840 x 2160 with a 60 Mbit/s bit rate. It provides 12X optical zoom and records to a SDXC memory card. In February 2015, Sony launched the consumer video camera, FDR-AX33, which uses XAVC S. It provides a maximum resolution of 3840 x 2160 and increased the bit rate to 100 Mbit/s. It provides 10X optical zoom and records to a SDXC memory card. In late fall, 2015, Sony released
