DVCPRO HD Frame Rate Conversion add noise

We have shot some footage (DVCPRO HD 720p 59:94) converted just fine for SloMo. Though noticed it adds more noise. The noise flickers and rotates. Anybody else have this problem. We think it might be a problem in post(in conversion) In production we used the varicam shooting at 60fps using pro 35mm adapter and using a swing and tilt lens. I believe the noise is coming from the adapter but not sure.

PLEASE HELP!

Mac Pro, Mac OS X (10.4.9), 2 x 3Ghz Dual Core Xeon, 5GB Ram, ATI Radeon X1900

Sorry, but I do this a lot and I can't say that I have seen this issue.

What version of QT are you running? What OS?

Since all FCP is doing is transferring frame for frame making 60 frames into 24...data copying with no recompression, I don't see how the lens could be the issue. Step thru the 60fps frame by frame, then the same frames on the 24p footage...see if the distortion is the same. with the 60fps it goes by so fast you might not be seeing it.

Noise is in your lens set up somewhere, I think maybe the adapter, I don't know why, but have heard this rumor before.
