Abstract: Non-limiting examples of the present disclosure describe detection of gross motion of a region of content. Gross motion of a region of content may be detected. A determination may be made as to a current quality level of the region. Based on detection of the gross motion, residual values may be generated for a progressive update of the region. The residual values are generated using the current quality level of the region as a base to determine a quantization update for a progressive update of the region at a higher quality level as compared with the current quality level of the region. Frame data for the progressive update of the region may be encoded. The frame data may comprise the residual values and motion vectors for progressive update of the region. The frame data may be transmitted for decoding. Other examples are also described.
