Upscaler

What it is for

Section titled “What it is for”

Settings › Upscaler is the picture pipeline — four of its tabs are the order things happen to a frame: repaired, enlarged, shrunk, finished. The neural upscaler is one of its choices, not a switch above it.

Settings, Upscaler selected in the rail with its Source, Upscaling, Downscaling, Output and Advanced sub-items. Beside it the caption How the picture is rebuilt at a higher resolution, the five tabs with Upscaling chosen, a Status row reading Passthrough — the neural upscaler is not running, then Picture enlargement with Stop using the net at and Luma upscale, Colour (chroma) with Chroma upscale, the two closed folds Filter shape — luma (advanced) and Filter shape — chroma (advanced), Sigmoidal upscaling on, and Neural strength with Strength at 1.00 and a note saying it has no effect while the net is not the active upscaler. The Edge halo limiter heading closes the picture; the tab carries on below it, Render scale with it.

How to use it

Section titled “How to use it”
  1. Status, under the tabs, says what the net is doing; unconfigured it reads Passthrough — the neural upscaler is not running.
  2. On Upscaling, under Picture enlargement, set Luma upscale to Neural model to turn the net on; Content type picks its family; Stop using the net at skips sources that already fill your display.
  3. Below sit Chroma upscale, Sigmoidal upscaling, Strength, Limit edge halos and Render scale.
  4. Every tab holds more rows than this page names: Source cleans the file (Reduce banding, Sharpness, CAS, Line darkening), Downscaling fits an oversized source, Output finishes it (Anti-ringing, Deinterlacing, Output dithering), and Advanced holds the model files and, under Engine, Execution provider.
  5. Click Save to keep it — see Saving changes.

Good to know

Section titled “Good to know”
  • The net needs a model file: Base model, Anime model and Live-action model, on Advanced. While it is not the active upscaler, Strength and Limit edge halos say so underneath and stay editable. Their note calls the picker Image upscale, a row that no longer exists.
  • The first play after a model or provider change is slower — Status reads Optimizing for your GPU….
  • Picture covers colour and placement; Rendering the decoder and frame delivery.
