Granularity
Most video data capture formats impose restrictions on the possible width and/or height of the
video, referred to as granularity restrictions. For example, the I420 capture format requires that the
capture width be a multiple of 16 and the capture height be a multiple of 2.
The granularities for all products in PostProcessing Mode are as follows:
Format Horizontal Vertical
RGB32 4 1
RGB24 4 1
RGB555 4 1
Grayscale 4 1
YUY2 4 1
UYVY 4 1
I420 4 2
YVU9 4 4
