Illustrations are pixelated

[christianj3906440]

Hi!
I have some vector illustrations in my project. They are all pixelated - I have ticked the box "Continuously rastersize". Does anyone know what it may be due to?
I have not experienced the problem before.
 
I'm working in After Effects 17.7.0 and had tried newer versions but without any improvements.

Your AE zoom-in ratio is set to 400 ,   anything beyond 100 will look pixelated

I know it will look pixelated. But when I export the video it also looks pixelated?
