Help with animated wallpaper

[wooden arrow]

Hi! I've been rigging models for a few months now and I'm still learning how to use live2d well. Now I wanted to start trying to make animated backgrounds, but I was wondering if there is any drawing resolution that is recommended, and the same with the export settings.

Could you give me some advice, it would be very helpful ;;

Use standard wallpaper size, like 4K resolution max
Brian Tsui has video of him animating an illustration in his channel, its like 11 hours long. Maybe you can use that for reference
