ProRes 4444 XQ


ProRes 4444 XQ is a welcome addition now that the Black Magic Production Camera 4K's 1.8 software update allows for RAW CinemaDNG capture. Especially with large screen size and UHD, fragmentation and aliasing becomes apparent a lot quicker than 1080p, making more information to describe the picture (data rate) drastically important.
Apple ProRes 4444 XQ
The highest-quality version of Apple ProRes for 4:4:4:4 image sources (including alpha channels). This format has a very high data rate to preserve the detail in high-dynamic-range imagery generated by today’s highest-quality digital image sensors. Apple ProRes 4444 XQ preserves dynamic ranges several times greater than the dynamic range of Rec. 709 imagery. This holds true even against the rigors of extreme visual effects processing in which tone-scale blacks or highlights are stretched significantly. Like standard Apple ProRes 4444, this codec supports up to 12 bits per image channel and up to 16 bits for the alpha channel. Apple ProRes 4444 XQ features a target data rate of approximately 500 Mbps for 4:4:4 sources at 1920x1080 and 29.97 fps.
ProRes 4444 XQ is supported on OS X Mountain Lion v10.8 or later.
