How to extract the best quality from cineframe footage?

I have to edit a video that has been shooted with two cameras, a Z1 and an EX1. The EX1 was set to 1080/25p and the Z1 had the Cineframe mode on. I will edit it on a Final Cut Pro station.

My question is: how to handle the Z1 footage to give it maximum sharpness and make the color artifacts invisible?

Here's what I have found after plaing with FCP for a while:
- The Flicker filter gives away with the color artifacts, but it makes the Y channel a bit soft (obiovusly).
- If I put the Z1 clips in a 25p sequence, FCP will deinterlace them automatically and there's no option (at least I don't know) to force both fields on. I don't know how the cineframe mode works, if it just stores the same information for both fields, then deinterlacing will be a good option.

Anyone knows how could I work on the YCbCr channels separately and then put them together again? This is to put different filters in the Y channel and the CbCr channels. The different composition modes that FCP provides cannot do this (I think).

The Cineframe mode deinterlaces prior to compression, and does some kind of interpolation. The footage should be treated as progressive. You may try some 4:2:0 artefact removal, but you should not deinterlace.

I don't know how to do this in FCP though. I use Cineform's HDLink for capture, which automatically renders Cineframe footage as progressive.
