Plane Downscaler
Chroma plane downscaler used during YUV to RGB conversion. This filter controls how chroma planes are downscaled when the source resolution exceeds the display resolution.
Available Options
| Filter | Internal Name | Description | Speed |
|---|---|---|---|
| None (follows downscaler) | none | Use the same filter as the main downscaler setting | -- |
| Hermite | hermite | Hermite-weighted averaging | Fast |
| Bilinear | bilinear | Bilinear (triangle) averaging | Fast |
| Bicubic | bicubic | Bicubic interpolation | Fast |
| Gaussian | gaussian | Gaussian smoothing | Fast |
| Catmull-Rom | catmull_rom | Catmull-Rom cubic spline | Medium |
| Mitchell | mitchell | Mitchell-Netravali cubic spline | Medium |
| Lanczos | lanczos | Lanczos reconstruction | Medium |
Default: None (none) -- follows the main downscaler setting.
Recommended Settings
- None is the default and uses the same filter as the main Downscaler, which is appropriate for most use cases.
- A separate plane downscaler is rarely needed. Consider setting one only if you want to use a cheaper filter for chroma to reduce GPU load during downscaling.
