1. A method for encoding video using scene change detection, the method comprising:
determining a sliding MCR score using a motion compensated residual (MCR) for video frames provided to an encoder; and
providing a prediction of when a scene change occurs to the encoder based on a regression of the MCR score and a comparison of the sliding MCR score to a sliding mean of the MCR score.
