Abstract: The present disclosure discloses a conversion method and device for a high dynamic range format, wherein the method comprising: performing, for each frame of data of HDR10 standard content to be converted, a processing of converting each frame of the data to HDR10+ standard based on a preset set of format conversion arithmetic units and in accordance with a preset arithmetic unit execution order, updating HDR10+ standard metadata of corresponding scenes by using HDR10+ standard metadata that is obtained by the processing, wherein the set of the format conversion arithmetic units is obtained by splitting an algorithm for converting content data of HDR10 standard into that of HDR10+ standard in a hierarchical splitting manner, and the arithmetic unit execution order is obtained with a preferred target that an execution duration is the shortest; and inserting the HDR10+ standard metadata of all the scenes into video stream information of the HDR10 standard content to be converted to obtain corresponding HDR10+ content.
