Described are concepts, systems and techniques related to processing an input video signal intended for a first display to produce an output signal appropriate for a second display. The concepts, systems and techniques include converting using one or more transfer functions arranged to provide relative scene light values and remove or apply rendering intent of the input or output video signal, wherein the removing or applying rendering intent alters luminance.

Embodiments of this application provide a video processing method and apparatus. The method includes: receiving, by a first device, an operation of enabling photographing in a movie mode, where obtaining, by the first device, a first image sequence based on a camera in response to the operation of enabling photographing; performing, by the first device, encoding based on the first image sequence and first dynamic metadata corresponding to the first brightness scene, to obtain a first HDR video; obtaining, by a second device, the first HDR video from the first device; adjusting, by the second device, a brightness of the first HDR video based on a preset brightness, to obtain a second HDR video; and playing, by the second device, the second HDR video.
