XAVC is a open standard codec that is riddled with flexibility in image quality, colour space and coping with variable frame rates offered by cameras. Whether you’re making news, music promos or even 4K movies, XAVC offers reduced bitrates and file sizes without sacrificing on-screen quality. It supports 8 and 10 colour depths, providing maximum dynamic range for colour correction and grading as well as a wide range of 4:2:2, and 4:2:0 sample structures , to enhance the colour grading process, increase creative control and flexibility. XAVC has been designed to support all current popular AV media resolutions, including 4K, QFHD, 2K, HD and SD as a proxy. Sony outlines XAVC on their you tube channel - and its across their full range of cameras so whether your working with F55 or even right down to a handheld camera like PXW-Z90 - this codec can make life a lot easier for your workflows.
