Proteus Natural

Model Overview

Proteus Natural, is the next installment to our popular Proteus AI model. Like Proteus, this is intended as a general upscaler for most types of content and can render locally and on the cloud.

• Great for most video conditions and types

• Addresses compression and general digital artifacts

• Reduces halos common with older content

• Respects the original source material; doesn’t overly enhance/modify source inputs

• Clean upscale that does not distort or warp original source details

• Addresses aliased edges

• Great model to mix and match with a second enhancement

What’s the Difference between Proteus and Proteus Natural?

• This model takes the best out of Proteus and improves it with a more natural output that doesn’t over sharpen or “over enhance” everything.

• Though the original Proteus is quite robust, at times the background texture can appear extra sharp or crunchy. Natural, takes this into account and minimizes these types of issues.

• Additionally, smaller faces (background people -small in scale) can also have distorted faces as a result of Proteus trying to understand a face from pixels of low quality video data. Proteus Natural, reduces this issue and allows for a more subtle touch up rather than an over estimation of the face.

Things to Note

• Unlike Proteus, this does not have modifiable settings. It’s a “click and play” type of model.

• Due to the more natural intention with this model, it is worth noting that it is not the sharpest model available and this is by design. If additional sharpening is desired, it is recommended to couple this model with a second enhancement for the desired look.

• Though speed can be similar to Proteus, it can take a little longer.
