Constrained affine motion inheritance for video coding

Abstract:

An example device for coding video data may include a memory configured to store a current block of the video data and one or more processors implemented in circuitry coupled to the memory. The one or more processor may be configured to determine delta motion vectors from control point motion vectors of a neighboring block of a current block. The one or more processors may also be configured to clip the delta motion vectors to a predefined range. The one or more processors may also be configured to code the current block of video data using the clipped delta motion vectors.
