Abstract: Techniques related to designating golden frames and to determining frame sizes and/or quantization parameters golden and non-golden frames for video coding are discussed. Such techniques may include designating an frame as a golden frame or a non-golden frame based on whether the frame is a scene change frame, a distance of the frame to a previous golden frame, and an average temporal distortion of the frame and determining a frame size and/or quantization parameter for the frame based on the designation and a temporal distortion of the frame.

Abstract: Techniques related to constant quality video coding are discussed. Such techniques may include determining a quantization parameter for a frame of a video sequence, modifying the quantization parameter based on a spatial complexity or a temporal complexity associated with the video frame, and generating a block level quantization parameter for a block of the video frame based on the modified frame level quantization parameter, a complexity of the block, and a complexity of the video frame.

Abstract: Techniques related to video pre-processing for video coding are discussed. Such video pre-processing techniques may include applying adaptive temporal and spatial filtering to pixel values of video frames of input video to generate pre-processed video such that the adaptive temporal and spatial filtering includes blending spatial and temporal filtering of the individual pixel value when the block of pixels is a non-motion block and spatial-only filtering the individual pixel value when the block of pixels is a motion block.
