poor image quality(blur) when precomposing
I know this has been posted on the forums before, around 6 years ago but the resolution it came to was a suggestion that I can’t work with.
I’m running CS4 and have an 8-core with 10gb RAM. Whenever I precompose multiple compositions within compositions the imagery from the further nested compositions become progressively blurred. After 5 or 6 levels of nesting the graphics/videos become noticeably blurred and crappy looking compare to how they look directly in their comp.
I checked all the quality switches and because I have 3d cameras I cannot collapse transformations.
Does anyone know what could be causing this?
Thanks!

That’s exactly what’s causing it. Without collapse transformations turned on, AE treats your precomps as rasterized footage. In other words, a 1920×1080 precomp becomes exactly like a piece of 1920×1080 video. As you’re seeing, it won’t hold up well to repeated scaling.
Collapsing transformations allows AE to see all the way through your nested comps and get at the original footage. Any transformations can be computed with the original footage pixels, not the rasterized precomp of a rasterized precomp of a rasterized precomp’s pixels.
Unfortunately, the solution is to collapse transformations. You can preserve 3D through collapsed transformations, but you will need to rethink your camera work.

Thank you very much. I was having that exact issue and your answer helped me solve the problem without any hair-pulling. Can’t believe it was so easy…

Hello, I’m having a similar blurred image/text layer problem. However, in my case even a layer which is not precomposed, a text layer, is very slightly blurred when I switch on 3d. This occurs regardless of the camera settings, depth of field, etc.
Totally lost for a solution here. Any solutions or suggestions are appreciated.
Thank you.
