My review of Red Giant Shooter Suite’s Denoiser II will unfortunately be very brief, because it turns out to be not compatible with my NLE, Final Cut Pro X. Red Giant posts this on their site:

At this time there is a technical feature which FCPX lacks and Denoiser II requires to function correctly. Unfortunately if we were to disregard this component and just made the product available for FCPX, it would not be as reliable and the results would be far below our standards when compared to other host software that Denosier is compatible with.

I appreciate Red Giant’s statement and understand the vagaries of software development. Until Apple feels Red Giant’s pain, though, I’ll stick with Neat Video Denoiser, a company that has managed to ship a reliable solution in spite of all that.
