Result with various pre-and-post-filtering. The main gut of the work was done with 2X_DigitalFilmV5_Lite.
After (2X_DigitalFilmV5_Lite with some pre-and-post-filtering)

Comparison against the official Disney Blu-ray:
There wasn't really any issues with the original source to fix, but it did improve the sharpness while not over
doing it or causing other artifacts, unlike the official Disney Blu-ray, which did a terrible job.

Comparison against the official Disney Blu-ray:

Original Blu-ray release, completely unaltered. DNR'd removing a lot of fine detail, green tint across the
board, all edges have large positive lobes, edges are squashed/thickened and posterized, 4:3 cropped to 16:9,
then further cropped again, I could go on... -- Yes! They really released it like this...

After (2X_DigitalFilmV5_Lite with some pre-and-post-filtering, cropped to the same aspect ratio as Disney's Blu-ray)

As you can see they over-sharpened, posterized the image, removed detail, caused Halo'ing, added a sort of green
tint across the picture, and cropped in to 16:9 from a 4:3 source. Yikes!

Same ESRGAN result using the same pre-and-post-filtering and model, just cropped to the same aspect ratio as
Disney's Blu-ray. You're not seeing things, I didn't mix up the order of these results. The Disney Blu-ray
really was that crap!
I did not mix up the labels of these images. The one labeled as the Official Blu-ray release, really is like that!

Private 4x Model Applied (2880x1920 -> 1620x1080)

This model was trained to fix inaccuracies in the DVD's color, remove Halo'ing/Glow, and remove Chroma Droop. The
result is a very crisp output for a show originally animated in SD.
Fixed Halo'ing/Glow around outlines, and a bit of Chroma Droop. However, the colors between images in the dataset
pair had a mistake so it learned to modify the colors incorrectly.

Fixed slight inaccuracies in the Color, Halo'ing/Glow around outlines, Chroma Location Misplacement, as well as a
bit of Chroma Droop (on some scenes only). This is an almost perfect result (in my opinion). Do note that the
warping/stretch on the edges is an animation/dvd edit and not caused by VSGAN or the model.
