Problem with After Effects renders in FCP

I'm hoping someone can help me find a solution to the following problem:

Whenever I render a clip out through After Effects and try bringing into a Final Cut Pro sequence, the result is always very low-res. There's lots of aliasing on text and the whole thing just looks like garbage.

I've tried multiple variations on the render settings, but it's always the same result, even when exported from Final Cut as QT files. The clips coming from AE look fine when played with Quicktime and when dropped into other NLE's. I'm sure this is an issue with FCP, but I figured this was the place to post since I'd have a better chance of finding an AE user that has encountered the same issue.

Anyone have a solution? Suggestion?
