No more HLG afther version 5.43

[Genine-Collin]

@rigaya It"s holding me down to update to an later version because i'm losing the HLG option. I'm using your program together with Fastflix of cdgriffith and stumbled an a problem with fastflix using the seek to option and the solution was to update nvencc. cdgriffit ask me kindly to report this issue to you Normal when i'm using the command of nvenc dolby vision 8.4 it's getting the HLG option and then i add the atc-sei bt2020-10 witch works perfect When updating to a newer one it won't work anymore The left image is the newer 7.22 i think all the version afther 5.40 won't work

[rigaya]

Would you please let me know the whole commnand line?

When using dolby vision profile 8.4, parameters below should be used (or these three can be omitted when --dolby-vision-profile 8.4 is set).

--colorprim bt2020 --colormatrix bt2020nc --transfer arib-std-b67

Would you please check again if you have set these properly?

NVEnc 7.13 changes behavior handling --dolby-vision-profile.

Previously --dolby-vision-profile has overwritten values of --colormatrix, --colorprim, and --transfer, but now it is the opposite due to user request. Now, --colormatrix, --colorprim, and --transfer will overwrite --dolby-vision-profile.

Therefore, you need to specify the correct values ( --colorprim bt2020 --colormatrix bt2020nc --transfer arib-std-b67) or simply omit those.

Actually, one weird thing is that NVEnc 5.40 you have mentioned even does not have --dolby-vision-profile option, it has been added in NVEnc 5.43.
