Comment (by Tom B):
I've just installed ffmpeg from https://aur.archlinux.org/packages/ffmpeg-
git/ which pulls it from: https://git.ffmpeg.org/ffmpeg.git
The output is the same. nnedi af mode gives gives flickering top.bottom
rows.
```
ffmpeg -i "original.mkv" -c:v libx265 -crf 23 -vf nnedi=weights.bin:all:af
-c:a copy nnedi.mkv
