Abstract: A format for use in encoding moving image data, comprising: a sequence of frames including plurality of the frames in which at least a region is encoded using motion estimation; a respective set of motion vector values representing motion vectors of the motion estimation for each respective one of these frames or each respective one of one or more regions within each of such frames; and at least one respective indicator associated with each of the respective frames or regions, indicating whether the respective motion vector values of the respective frame or region are encoded at a first resolution or a second resolution.

Abstract: An apparatus for encoding video data, the apparatus comprising a compliance module configured to compare a resource requirement associated with encoding video data to form at least part of an encoded frame using a standard encoding mode with an acceptable resource level and an encoder configured to, responsive to a determination that the resource requirement will exceed the acceptable resource level, form the at least part of an encoded frame by encoding some of the video data using the standard encoding mode and filling a remainder of the at least part of the encoded frame with data that is associated with a lower resource usage than data generated using the standard encoding mode.

Abstract: An input of an encoder receives moving image data comprising a sequence of frames to be encoded, each frame comprising a plurality of blocks in two dimensions with each block comprising a plurality of pixels in those two dimensions. A motion prediction module performs encoding by, for at least part of each of a plurality of said frames, coding each block relative to a respective reference portion of another frame of the sequence, with the respective reference portion being offset from the block by a respective motion vector. According to the present disclosure, the moving image data of this plurality of frames comprises a screen capture stream, and the motion prediction module is configured to restrict each of the motion vectors of the screen capture stream to an integer number of pixels in at least one of said dimensions.
