Abstract
The present invention is related to video encoding. In an embodiment, a first root mean squared (RMS) value is calculated for a first frame relative to a second frame, and a second frame relative to a third frame. A second temporal derivative RMS value is calculated. Based at least in part on the second derivative value, the second frame is designated as a scene change frame.
