Script fails with 1920 input

[tilsammans]

The script assumes input resolution higher than 1920.

Hi @tilsammans,
This was for 2 reasons:
1 - the input should be a high resolution video. But this could change ofc.
2 - My original base videos when I made the script had a higher resolution than 1920 too.

I could make the script more flexible, however, I can’t help you right now! Can you try to fixe it and pushing a pull request? Same to #2

I already have a pull request open though, are you merging?
