Which profile are you using to produce the video and how are you uploading to YouTube, directly or through PowerDirector?
I use a custom profile 1920x1080 with 25fps. I encode an MKV with PowerDirector (currently version 16) and upload to Youtube directly.
Apologies for the delay but I did not receive a notification that replies had been posted.
I tried converting the encoded video with mkvmerge to add the necessary HDR metadata, however now when I upload to YouTube, I get the message "You uploaded an HDR video, but the pixel format is incorrect. For more information on best practices for creating HDR content, please refer to this article."
Turns out the pixel format should be 10-bit, but Powerdirector does not support it in its output formats. Even if it did, I'm not sure it would make sense to convert 8-bit video to 10-bit video. So HDR remains a dream for the time being (I don't have a camera which records 10 bit in any case)
