I’m enhancing some old DVDs and I noticed occasional large, black splotchy artifacts generated by the Proteus model at settings of 300% scaling or above. (I couldn’t reproduce it in Artemis or Gaia, or Proteus at 200% or 100% scaling settings. But 300%+ shows the artifacts.)
If you’d like to try it for yourself, here’s the input file. It’s a lossless AVI in the YUV420 colorspace using the free “Lagarith” codec.
Thanks for looking into this. Proteus is the model I use 9 out of 10 times. I’ve seen other instances of these black splotches too, so this isn’t a one-in-a-million case.
