Abstract: A method comprising: obtaining a video bitstream comprising a high dynamic range (HDR) video representation; obtaining one or more tone mapping operators and an indication of at least one tone mapping operator to be applied; and modifying the HDR video representation into a low dynamic range (LDR) video representation using said at least one tone mapping operator determined by said indication.
