TL;DR: I want to inject an Dolby Vision P8. 1 RPU into an 1080p film, how?
I don't think x264 supports HDR, so I'm assuming the 1080p track is a SDR one.
Thank you for your reply, and sorry for my late reply.
The 1080p files are indeed SDR.
I'm getting mixed results, researching online whether H.264 supports HDR or not. However, Wikipedia states the following:
Wikipedia wrote:Throughout the development of the standard, additional messages for containing supplemental enhancement information (SEI) have been developed. SEI messages can contain various types of data that indicate the timing of the video pictures or describe various properties of the coded video or how it can be used or enhanced. SEI messages are also defined that can contain arbitrary user-defined data. SEI messages do not affect the core decoding process, but can indicate how the video is recommended to be post-processed or displayed. Some other high-level properties of the video content are conveyed in video usability information (VUI), such as the indication of the color space for interpretation of the video content. As new color spaces have been developed, such as for high dynamic range and wide color gamut video, additional VUI identifiers have been added to indicate them.
I'm assuming this means H.264 supports HDR or?

If that's the case, you can try muxing it into Profile 8.2 or Profile 9.
How would I go about converting to Profile 9? The dovi_tool github page doesn't seem to mention this.
I would like to at least give it a try, or I'll wait for / request a 1080p Web-DL with Dolby Vision... Unfortunately, the 1080p version of one of my favorite films objectively looks much better than it does in 2160p. It's so badly upscaled. Hence why I want to get the best of both worlds.
