Abstract
Embodiments of the present application provide a video processing method, device, computer equipment, storage medium and program product, which comprises: encoding an image block to be encoded in a video, dividing the image block according to a first division manner, and encoding a plurality of sub-blocks obtained by the division; in the encoding process, if the image block is subjected to translational inter-frame prediction, any sub-block of the plurality of sub-blocks is not further divided, and motion information when the plurality of sub-blocks are subjected to inter-frame prediction is consistent with motion information when the image block is subjected to inter-frame prediction, a reference frame used when the image block is subjected to translational inter-frame prediction is set as a limited reference frame of the image block; the limited reference frame is used as a reference frame for other sub-blocks obtained by dividing the image block according to a second division manner, and a further divided block of the other sub-blocks subjected to inter-frame prediction. By using the embodiments of the present application, the decision process of reference frame selection can be simplified, the selection efficiency of the reference frame can be accelerated, and the video encoding efficiency can be improved.
