Then delete this entries, they will be not written, if they not exist.
Do not set Fake entries how 0,0 or something.

I assume "Display P3" is the P3D65 you mentioned?

Display P3 = P3D65 correct!

Isn't quietvoid's tool suited for HDR10+? Or do you mean adding the metadata without re-encoding?
|
This is a HDR10+ Metadata parser, who reads the bitstream and save all HDR10+ metadata in a JSON textfile. While encoding you must write this Data into the bitstream.
No chance to implent HDR10+ metadata after Encoding in a HDR10 bitstream.

So basically we need a tool that reads all metadatas from the source file and copies them over to the encoded file. Therefor the encoded file has to have the very same frame structure as the source, I guess?

I have build a tool for me, that reads HDR10 and HDR10+ metadata and write the commands for x265 in a txt file. The Problem is, i must solve the P3 / BT2020 Alghorythm, i use DGindexNV for this,
so this tool works only with a NVideo Geforce GTX 1050 and above.
