Abstract: A method for cloud gaming including generating video frames when executing a video game at a cloud gaming server. The method including predicting a scene change for a first video frame for the video game, wherein the scene change is predicted before the first video frame is generated. The method including generating a scene change hint that the first video frame is a scene change. The method including sending the scene change hint to the encoder. The method including delivering the first video frame to an encoder, wherein the first video frame is encoded as an I-frame based on the scene change hint.
