Example of setting values
(A) : Bit rate
(B) : Color sampling
(C) : Bit depth
The higher the bit rate, the higher the image quality.
Color sampling (4:2:2, 4:2:0) is the recording ratio of color information. The more uniform this ratio is, the better
the color reproducibility, and it is possible to remove colors neatly even when compositing using a green screen.
Bit depth represents the gradation of luminance information. When the bit depth is 8 bits, 256 levels of gradation
can be obtained. When the bit depth is 10 bits, 1024 levels of gradation can be obtained. A larger value enables
smoother expression from dark to bright areas.
[4:2:2 10 bit] is a setting that assumes that the recorded movie will be edited on a computer. The playback
environment for [4:2:2 10 bit] is limited.
