Scale compostion without losing quality

[Cerikis]

Hi there, 

I have a composition with a tournament bracket. But I want to zoom in on a part of it. 

So I want to zoom in on a particular game ( team vs team ) and that without losing quality. I've tried using a vector but it didn't work so far. Tried .eps and .ai but I need all the layers and high quality when I zoom in. Could someone help me with this? Saw the other article but wouldn't work for me yet.

If you are using vector files you will get sharp graphics. Be sure you are using Continuous Rasterize button when scaling layers (the sun icon on the switches panel).
