Workflow for content creation and guided display management of EDR video

A method for guiding the display management of enhanced dynamic range (EDR) images in a video sequence, the method comprising, in a decoder:

• accessing a first set of metadata (110) for a first image color graded on a first reference video display;
• accessing a fourth set of metadata (255) for a second image color graded on a second reference video display, wherein the first and second images represent the same scene;
• receiving image data (107) for the first image;
• accessing a set of parameters (215) for a target video display;
• generating a mapping function (240) using the first set of metadata, the fourth set of metadata, and the parameters of the target display;
• and
• mapping (230) the image data for the first image into the target display using the image data, the generated mapping function, and the parameters for the target display,
• wherein the fourth set of metadata is generated by an encoder and transmitted to the decoder,
• wherein generating the fourth set of metadata in the encoder comprises:
• generating (120) a second set of metadata for the second image color graded on the second reference display;
• and
• applying a metadata transformation (250) to the second set of metadata to generate the fourth set of metadata;
• wherein the method is performed by one or more computing devices.
