So, it’s come to my attention that I can use the Proteus AI model in Video Enhance AI to retain the original grain from the source rather than having to add an extra grain layer in post. For the purposes of preservation, this might be the better way to go…

EDIT: On the other hand, retaining the original grain has the side effect of retaining more sharpening and compression artifacts. The grain doesn’t look entirely natural and uniform. Since this is animation and doesn’t have a lot of fine detail that is lost with DNR, the original approach might have been the best…what matters most, authenticity to the source or a pleasing image?
