of 10-bits and 4:2:2 chroma subsampling is possible with Sony's XAVC codec. * All Intra-frame system that compresses each frame individually to achieve best quality. * When recording 4K movies in the XAVC HS format is an optional which is using a HEVC codec ( H.265) and has high compression efficiency. ** The camera can record movies with higher image quality than XAVC S movies but the same data volume. * Camera can record in "Long GOP" codec ( H.264) compression which is compressing multiple frames to reduce file size.
