As you added 10 bitdepth the encoder automatically changed to the profile MAIN10, which has nothing to do with the VVC codec. At least this is recommended in the .cfg settings.
Of course you can change the parameters so that the encoder changes for the 12 bitdepth profile settings to MAINREXT.
Code:
m_bitDepthConstraint     = ( ( m_profile == Profile::MAINREXT || m_profile == Profile::NEXT ) ? 16 : 8 );
Oh, ok, I got it. When I have time, I'm gonna try to make a few tests and I'm gonna be back here with the results. I was thinking about running some ssim/psnr tests, but since there are no decoders available to natively read it, I would have to re-encode it to a lossless format and then run ssim/psnr; the only problem is that I have no idea how to do that. Is there something to actually re-encode a VVC file? Otherwise I think I'm just gonna use my eyeballs.
