Shape layers shaking when i zoom with 3d camera

[default0dmat7jopgqw]

I have made a small animation, comp size is also small to fit in other animation.

Some of the shape layers start to shake when I zoom in as in the edges become blurry.

I have checked continuously rasterize on all layers. 

Is it because they are png's?

found this response and will try. It probably has to do with png size and scaling it up

Scaling anything rasterized above 100% will start to result in quality loss. Scaling it WAY above 100% will usually result in blurry, heavily-pixelated edges. Continuously Rasterize only works on vector files or pre-comps (where it technically becomes "Collapse Transformations").

I'm a little unclear about whether you're using PNG files, shape layers, or both. Some screenshots would help us diagnose your issue, if Rick's suggestions in that other post you linked don't solve it.

Thanks for the reply.

I ended up using bigger sized png's and scaled them down and no more blur .
