I used adobe illustrator for making text (we all know that ai and svg formats uses vector graphics instead of pixels so zooming couldn`t pixelazie anything). But when i zoom it in After Effects it has no difference from simple pixel text whatsoever.
My question here is - HOW TO MAKE IT NON PIXELATED?
This is a pretty simple fix. AE has to rasterize vectors at some point because the output from AE is pixel-based. You can ensure this rasterization looks good by clicking the "continuously rasterize" switch. You may have to hit the Toggle Switches / Modes button to see the switches.
In the example below, the vector text looks terrible when scaled up to 700%, until the switch is hit.
