Noise Reduction always processing
Have a multicam clip wherein two of the angles need noise reduction. Dragged the FCP effect onto those sub-clips, but even after several hours there's still text in the bottom left of those clips that says "Processing Noise Reduction...".
Clips are only a few minutes long. Only the frame I had skimmed to when the NR effect was added looks like noise reduction has been applied.
