Plane Upscaler
Chroma plane upscaler used during YUV to RGB conversion. Most video content uses 4:2:0 chroma subsampling, meaning the chroma (color) planes are half the width and half the height of the luma (brightness) plane. This filter controls how those chroma planes are upscaled to full resolution.
Available Options
| Filter | Internal Name | Description | Speed |
|---|---|---|---|
| None (follows upscaler) | none | Use the same filter as the main upscaler setting | -- |
| Nearest | nearest | Nearest-neighbour (box) sampling | Very fast |
| Bilinear | bilinear | Bilinear sampling | Very fast |
| Oversample | oversample | Aspect-ratio preserving nearest neighbour sampling | Very fast |
| Bicubic | bicubic | Bicubic interpolation | Fast |
| Gaussian | gaussian | Gaussian smoothing | Fast |
| Catmull-Rom | catmull_rom | Catmull-Rom cubic spline | Medium |
| Lanczos | lanczos | Lanczos reconstruction | Medium |
| EWA Lanczos | ewa_lanczos | EWA Lanczos (Jinc) reconstruction | Slow |
| EWA LanczosSharp | ewa_lanczossharp | Sharpened version of EWA Lanczos | Slow |
| EWA Lanczos4Sharpest | ewa_lanczos4sharpest | Very sharp EWA Lanczos with anti-ringing | Very slow |
Default: None (none) -- follows the main upscaler setting.
Recommended Settings
- None is the default and uses the same filter as the main Upscaler, which works well in most cases.
- Setting a separate plane upscaler lets you use a faster filter for chroma without affecting luma quality, since chroma detail is less perceptually important.
- Bilinear or Bicubic are reasonable choices for chroma-only upscaling to save GPU time while keeping the main upscaler on a high-quality setting.
