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.
