-> The letterboxing is wrong. AddBorders can't be used with negative values and the gui should not allow this.

Selur, thanks for the quick response!
I was able to upscale the h264 converted file on AME when I untick the Letterbox option.

I have a saved XML preset to resize SD files.

I open Hybrid, apply the XML profile, open the original mpeg SD file 6002688.mpeg
https://drive.google.com/file/d/1hvZKmJx...R7gbV/view

and Hybrid gets stuck at about 98%, as seen on the log I shared earlier:
