Use this setting only when you also enable Scene change detection. This setting determines how the encoder
manages the spacing between I-frames that it inserts as part of the I-frame cadence and the I-frames that it
inserts for Scene change detection. We recommend that you have the transcoder automatically choose this value for
you based on characteristics of your input video. To enable this automatic behavior, do this by keeping the
default empty value. When you explicitly specify a value for this setting, the encoder determines whether to skip
a cadence-driven I-frame by the value you set. For example, if you set Min I interval to 5 and a cadence-driven
I-frame would fall within 5 frames of a scene-change I-frame, then the encoder skips the cadence-driven I-frame.
In this way, one GOP is shrunk slightly and one GOP is stretched slightly. When the cadence-driven I-frames are
farther from the scene-change I-frame than the value you set, then the encoder leaves all I-frames in place and
the GOPs surrounding the scene change are smaller than the usual cadence GOPs.
