Creating a "Convert Dolby Vision Profile 7 to Profile 8" feature requires a specific technical approach because Profile 7 (typically found on discs) contains a secondary "RPU (Reference Processing Unit) track" that most TVs and streaming devices cannot read. Profile 8 "bakes" this HDR data into the video stream, making it compatible with standard Dolby Vision TVs.
