Add Filters

Vapourkit lets you write and chain custom VapourSynth filters before and after the AI upscaling step.

Adding a filter

1. Click + Add Filter in the filter panel.
2. Configure it:
   • Pick a filter template, or write custom VapourSynth code.
   • Enable or disable individual filters.
   • Reorder filters using the drag handles.
3. Filters are automatically applied during processing.

Creating a filter template

Once you’ve written a filter you want to reuse:

1. Write the custom VapourSynth code in a filter.
2. Click Save as Template.
3. Name your template and optionally add a description.
4. Reuse the template in future projects.

Templates are stored as .vkfilter files — see File Formats.

Pre-made filters

Vapourkit ships with 160+ pre-made filters on Windows, covering antialiasing, denoising, sharpening, color correction, deinterlacing, and more. Linux exposes a curated subset whose Python and native dependencies are verified by Linux setup. See the Filter Reference for the full catalog and Platform Support for the platform split, then use the app’s filter picker to see what is available on your platform.

Linux filters

Linux does not install arbitrary third-party native plugins or Windows-only Hybrid scripts. A custom filter can use any API provided by the Linux setup, but it will fail during preview or processing if it imports a package or plugin that is not installed. See Write Custom Filters for platform-specific guidance.

Writing your own
