minIInterval

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. When you 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.
