Animated object losing resolution...please help.

Question

I have created a vector tree in Adobe illustrator and have imported it After effects, I then proceeded to laying out three of the images in after effects then offsetting two of the objects by a pixel all in 6 frames, and when looped it has an animated feel to the vector.
The 3 images are constantly looping all in 6 frames. I then pre-composed that sequence and have created a 5 min sequence of this still tree that looks animated.
The problem that I am having is that, I would like to zoom in and out of this still animated tree but when I zoom in, it loses resolution.
I am thinking I am not able to do this by pre-composing, are there any solutions to this?
I posted the video here and this is the video I would like to zoom in and out of, but how do I make it so that it does not lose resolution?

For each of the AI layers in the nested Comp, you have to turn on the Constinuously Rasterize switch. This will preserve the scalable nature of vector graphics.
For more information, see Continuously Rasterize a layer containing vector graphics in AE Help.
But, since you are scaling up the Pre-Comp with its' own scale property, you also need to turn on Collapse Transformations for the Pre-Comp. It's exactly the same button as Continuously Rasterize, but when used on nested Comps it's called Collapse Transformation. It connects the properties of a Pre-Comp with the same properties for the layers nested in it, so that the Pre-Comp gets smart about things like combined scale values, etc.
For more information, see Render order and collapsing transformations.
