As a complete beginner, I'm using Gimp for animated gifs. I created lots of custom brushes for universal in-betweens: faces, eyebrows, arms, lips, etc.. I find it very time-saving.
In scenes where I make characters only half smaller, all shapes already appear very pixelated in gif and mp4 formats... The smaller I make characters, more pixelated they become. They are pixelated no matter what the size.
The sizes of the brushes when created vary between 100x50 px, and up to 700x600 px - maybe this could be a factor?
Are there any solutions for pixelation within Gimp?
I couldn't find any other software also for animation with custom brushes option except Gimp. Are there any?
