Is there any chance that somewhere, accessible, there might be a list of the parameters for the NVENC encoders along with what they do. It seems impossible to get this information without downloading an SDK and looking at source code. Nowhere is there a list of encoder options. IF you want to find anything you seem to have to subscribe to yet another developer network, determine which image is a traffic light, do an email verification, explain what country you are in and - to cap it all date of birth and name ID thieves should look here!
All I wanted to do was set up an encoder in OBS but the encoder options seem to be shrouded in mystery, like secret texts for the cognoscenti.
Do I sound mad - yes I am because this should not be the way it is.
