Abstract
Embodiments of this application provide a video encoding method, a video decoding method, and an apparatus. The video encoding apparatus may obtain source data, where the source data includes first high dynamic range HDR data and a first standard dynamic range SDR bitstream for same video data; map reconstructed data of the first SDR bitstream to second HDR data based on a correspondence between the reconstructed data of the first SDR bitstream and the first HDR data; determine a target residual value between the second HDR data and the first HDR data, where a bit width of the target residual value is less than or equal to a data bit width for encoding a first SDR video into the first SDR bitstream; encode the correspondence and the target residual value, to determine preset data; and transmit the first SDR bitstream to which the preset data is added.
