Custom 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 150+ pre-made filters covering antialiasing, denoising, sharpening, color correction, deinterlacing, and more. See the Filter Reference for the full list.
