Systems and techniques for video coding and compression are described herein. Some examples include affine coding modes for video coding and compression. One example is an apparatus for coding video data that includes a memory and a processor or processors coupled to the memory. The processor(s) are configured to obtain a current coding block from the video data, determine control data for the current coding block, and determine one or more affine motion vector clipping parameters from the control data. The processor(s) are further configured to select a sample of the current coding block, determine an affine motion vector for the sample of the current coding block, and clip the affine motion vector using the one or more affine motion vector clipping parameters to generate a clipped affine motion vector.
