Color Distortion

Hello,

I created a file in illustrator with the RBG setting and the preset, Film and Video (3840x2160) so I could get a high quality video when I export it. When I am in CH and I click render as vector, the text on my screen dissapears, Im not sure how to get it to render my text as vector for better quality because when I export throught ME the colors are duller in the final video. I would like the colors to look as crisp as the CH file. I attached a comparison below, I would appreciate any help? Thanks!
