Btw how do you guys handle a video source with dynamic tone mapping?
Code:
HDR_Format/String : SMPTE ST 2094 App 4, Version 1, HDR10+ Profile A compatible

You would copy each frame's HDR10+ metadata into the reencoded version of that frame. It's just an SEI message. I'm not sure if there are any tools that can do that simply. Probably mp4box, as it can do pretty much anything with long enough a command line and patient enough trial and error
.
But it needs to be done correctly. A four frame offset could lead to some quite strange behavior around edits. Also, it only matters if you have or are planning to have a display device that supports HDR10+. The nubmer of which are growing. But if you skip it, you'll still have a normal HDR-10 file with static metadata.
