Relates to the GOP structure. The GOP size (keyframe interval) in the units specified in gopSizeUnits. If you do
not know what GOP is, use the default. If gopSizeUnits is frames, then the gopSize must be an integer and must be
greater than or equal to 1. If gopSizeUnits is seconds, the gopSize must be greater than 0, but does not need to
be an integer.
