Abstract: A video coder may include a current picture and a reference picture in a reference picture list. The video coder may determine a co-located block of the reference picture. The co-located block is co-located with a current block of the current picture. Furthermore, the video coder derives a temporal motion vector predictor from the co-located block and may determine the temporal motion vector predictor has sub-pixel precision. The video coder may right-shift the temporal motion vector predictor determined to have sub-pixel precision. In addition, the video coder may determine, based on the right-shifted temporal motion vector predictor, a predictive block within the current picture.

Abstract: Techniques coding video data, including a mode for intra prediction of blocks of video data from predictive blocks of video data within the same picture, may include determining a predictive block of video data for the current block of video data, wherein the predictive block of video data is a reconstructed block of video data within the same picture as the current block of video data. A two-dimensional vector, which may be used by a video coder to identify the predictive block of video data, includes a horizontal displacement component and a vertical displacement component relative to the current block of video data. The mode for intra prediction of blocks of video data from predictive blocks of video data within the same picture may be referred to as Intra Block Copy or Intra Motion Compensation.

Abstract: In an example, a method of decoding video data includes generating a residual block of a picture based on a predicted residual block including reconstructing one or more residual values of the residual block based on one or more predicted residual values of the residual block. The method also includes generating a current block of the picture based on a combination of the residual block and a prediction block of the picture.

Abstract: An example method of encoding video data includes determining a resolution that will be used for a motion vector that identifies a predictor block in a current picture of video data for a current block in the current picture of video data; determining, based on the determined resolution, a search region for the current block such that a size of the search region is smaller where the resolution is fractional-pixel than where the resolution is integer-pixel; selecting, from within the search region, a predictor block for the current block; determining the motion vector that identifies the selected predictor block for the current block; and encoding, in a coded video bitstream, a representation of the motion vector.
