Abstract
A video encoding method is provided when three scenes are separated by two closely spaced scene changes. For scene changes spaced greater than a threshold, scene changes are programmed with I frames in a normal fashion. If less than the threshold, the method encodes depending on complexity of the first, second and third scene to determine how to encode the scene changes. To compare complexities, the process begins by using X, X, and Xto note respectively the complexities of the first, the second and the third scenes. If the absolute difference of Xand Xis higher than a first threshold and the absolute difference of Xand Xis higher than a second threshold, the first scene change is more significant than the second scene change, so in that case the process encodes the first scene change as an I-frame and picks a quantization parameter (QP) based on the complexity blended from the complexity of scene(X) and scene(X).
