Questions - Resolution and Colorspace #4
Description
Hello! Thanks for authoring 'tunet'! This looks really promising. I'm just getting started with training and I have a few questions.
(As mentioned here #2 it would be great to enable discussions since this isn't really an "issue".)
-
Is there a resolution limitation under the hood? (If I provide a 4k file, is it getting resized during training?) I know there is the 512 and 1024 settings but not sure what that relates to.. (since crop size is a separate flag).
-
When creating the CatFileCreator Nuke script, I notice the image colorspace is being shifted to Rec 709 and back. Is it safe to assume that same transform to Rec709 is happening prior to training?
-
Is there a desired colorspace to start from for training? Is ACEScg/linear an appropriate space.. or should it be something else (log, Rec709)?
-
Lastly, are there any bit-depth limitations (should the input/training images be 8 bit, or will 16 bit work?)
