As a general rule that I follow, I render graphics out in the codec that the show will be finished at, unless it needs an alpha channel. This prevents FCP from having to render the files again. I do this because it’s more efficient and because I don’t always trust how FCP renders graphics.
Now having said that, animation files shouldn’t be going significantly soft when rendered in a DV timeline, so there is probably another solution for you.
