Purpose: artifact

This model attempts to make films upscaled to 4K with Topaz Gaia-HQ look more natural and filmic. It sharpens, adds film grain, and smooths out small artefacts from the upscaling process. I recommend adding a tiny amount of grain to the input to seed the model (you can do this in VEAI), otherwise the film grain will remain static across frames that don't move much.

Category: Foliage/Ground
Purpose: bad upscale

Images of plants, trees or other foliage upscaled with Photoshop Preserve Details 2.0. Sharpens and "subdivides" details and noise so it doesn't look upscaled.

Plants

Restore frames to their original look as on Drawings. Before analog transfer

Trained on thousands of 4K HQ Drawing scans, the purpose of this model is restore the frame to its original paper and plastic look, with a particular emphasis on textures and preserving those brushstrokes and natural lines. Not to be used with heavily grainy sources.
Note: The random white speckles are an unfortunate side effect of not filtering the dataset.

AnalogFrames 1.0

Upscaling of Numeric Animation from SD to HD with high texture retention.

A serious upgrade over 1.0. Much more universality. Can look good on both clean SD and noisy/grainy source frames. It still has a weakness against sources with strong halos and jagged edges and rainbowing. (Recommended that these issues are fixed beforehand with avisynth)

NumericFrames 2.0

Upscaling of Numeric Animation from SD to HD with high texture retention.

Provides the sharpest results yet. About 30% better than the base 2.0 version. But as the title says it's the most aggressive version of NF. Does it's best on animation with little to no textures. The model as well as any version of NF is not suitable at all for overly deteriorated/blurred and low quality TVRips and VHSRips copies of animation pieces.

NumericFrames 2.1-Aggressive

Upscaling of Numeric Animation from SD to HD with high texture retention.

Big leap from 2.0, especially as much as texture retention is concerned. But also deals much better with distant characters/shots.
