At this stage of the processing (deinterlaced, cropped, denoised, resized): there is no filter in Hybrid that would tackle this.

Lowering the resolution (to 720x, otherwise my Geforce 4080 RTX is too slow; still only @3.3fps) and using https://github.com/pifroggi/vs_undistort did help a lot: https://www.mediafire.com/file/w7cffn9ad0mo3sm/vs_undistort.mkv/file

I installed vs_undistort, by:
  1. installing the torch-add-on
  2. open a Terminal in my Vapoursynth folder and calling:
    python -m pip install -U git+https://github.com/pifroggi/vs_undistort.git

I used it using a custom addition before DAA (something behind the resizing), calling:
# requires colorformat RGBH
import vs_undistort
clip = vs_undistort.pytorch(clip, temp_window=10, tile_width=None, tile_height=None, overlap=None, scales=[True, True, True], interpolation="bilinear", device="cuda")
(this was before the 2.x release)
