Lately I have the problem that when I import my illustrator files into after effects, they become pixelated. Not only when I zoom, also when I scale them up. This annoys me and I can't seem to find a solution to fix it. Please help ;(
enable continuous rasterization/ work at higher DPI in AI to begin with, especially if you use stuff that creates pixel data there already like drop shadows or certain blending effects.
If you scale over 100% You need to Continually Rasterize them (turn on the sun) Also make sure your Quality & Sampling is Best. My image has both Best Quality and Continually Rasterize turned on. Finally make sure you are viewing your comp window at 100% scale and Full Resolution. That should do it!
