I have a Gif Animation, that was generated from a high resolution vector. I used Illustrator to make the vector, after effects to make the animation, and photoshop to make the gif. I have All the design files but when I try to export it, it appears grainy and colors glitch. Attached is what it looks like. I need to hire a freelancer who can export it so that it's clear, the stripes and colors are smooth, solid, and aren't posterized. As high quality as possible.
