Appendix: Advanced Settings for H.264

Setting		Explanation

ReferenceFrames		This value is the number of previous frames each P-frame can
		use as a reference. Recommended value is around 4 to 8. Each
		increase has reduced benefit and constant speed loss with
		higher CPU usage. However, 16 can be helpful for animated
		content, video game capture, CGI, and other similar content.
SceneChangeDetectThreshold		0 turns off scene change detection. Higher values of scenecut
		increase the number of scenecuts detected. A good default is
	40.

		IMPORTANT! Lowering the default causes less scene
		detections so it would use less IDR frames. Those are
		expensive heavyweight frames.
