Sometimes this works: Add a null, parent all layers to the null(assuming there aren’t any pre-existing nulls), select all, copy, create an HD comp, paste. Select the master null, hit S for scale, and scale everything up to fit in the HD comp.

If your text was created with AE text, it should be crisp, assuming no pre-comp issues.

This technique doesn’t always work well with 3D cameras and 3D layers.
