I agree with you that better documentation is well desired.
documentation is not the strong part of this product or any other products from Topaz.
I guess the best documentation on those you can read here: but that even lacks information.
I would say in general “Proteus” is the mainstream “Standard” 1st line treatment you should go with.
“Artemis” is more for poor quality or really grainy image - it recovers a lot but also destroys lots of details and make the image more “cartoonish” IMO.
Gaia is for high quality videos, but at lower resolution and need resolution bump.
the Dione: presets are for interlaced videos. I also found using it for Progressive scan videos being very good retaining image quality and details.
