Granularity Different video color space definitions impose pixel count and window
dimension restrictions that must be considered when cropping. The Granularity
box lets you know the number of pixels that will be cropped or added each time
you increment or decrement the crop size by one pixel. In the above example (2
X 1), the crop border will always change in multiples of two pixels horizontally
and one pixel vertically. Some color space modes force the granularity to
16 pixels or more in one or both dimensions.
