error when I render.
I get a “Width not divisible by 2” error when I render.
Some output encodings, especially the highly compressed (e.g. h.264) encodings, have special requirements, i.e. width/height need to be divisible by 2 or even 4.
Simply set the “Percentage Scale” to 60 or 100% and you will be rendering at the expected 1920 by 1080.
