Provided are a coding prediction method and apparatus and a computer storage medium. The method includes that; for a coding block of an intra prediction type, Motion Vector (MV) Predictors (MVPs) of at least two control points of the coding block are determined; affine motion model-based motion estimation is performed on the coding block based on the MVPs of the at least two control points to obtain a first coding parameter of the coding block, the first coding parameter indicating a group of coding parameters corresponding to a minimum Rate-Distortion Cost (RDcost) obtained by performing motion estimation on the coding block in a non-translation motion manner; and prediction coding is performed on the coding block based on the first coding parameter.
