How to change low resolution into high resolution

[Ramraj2003]

I Have made animation using illustrator file in after effects in low resolution

Now, how to change illustrator file with high resolution without losing animation and size ? 

[P.M.B]

Once you've rendered the animation there's nothing you can do.  You need to go back into after effects and resize everything.

How complicated that will be is impossible to say. It depends on the specifics of your project and your expertise with AE.

In the future you should create with the resolution you wish to render in in mind.

You could try going to File->Scripts->Scale Composition in After Effects.

If you still have the Composition in the After Effects project, activate the Continuous Rasterization in the Layers, create a new larger Composition and put the Composition of your animation in that new one, scale it to fit the size of the new Composition that is Larger, it activates the Continuous Rasterization again in the Layer of your nested Composition and you only have to render.

thank you!!!

Byron, thank you for this. I think it did what I wanted. Can you tell me based on the following if I now have a true UHD project? I made an HD Comp. I put a UHD file in it. Then created a new composition that was UHD. Dragged the HD comp in and changed the Transform Scale to 200%.  Done? It does appear to be less jaggy viewed at 100 compared to the HD at 200. 

When I tried to change every layer to Continuous Rasterization some things stayed small. Like text layers.
