Abstract
The present invention is related to video encoding. In an embodiment, a sequence of frames is received. For each frame in at least a portion of the sequence of frames, a corresponding mean of absolute differences value weighted by a temporal parameter between frames bracketing said each frame is calculated. At least partly based on the corresponding mean of absolute differences value weighted by a temporal parameter, a first frame in the sequence of frames is skipped.
