If it looks at the noise in a sample frame and it can be sure that what it looks at is actually noise then most of the hard work is already done and there is not much need for the best-matching noise profile at that point. I'd love a "first pass" automatic workflow which looks at the amount of noise in a sample-frame from a clip and guestimates the best-matching noise-profile.

Redrob wrote:(3) My typical projects use 4-7 cameras (3-5 different models), and the amount of noise will vary based on how much gain the operator how to apply when shooting in a changing-light environment. Any tips, other than going event-by-event? For example, if I own an FX7 and XHA1s - I can't just create an "FX7-low-gain" and "FX7-high-gain" profile (and same for the other camera) which applies in all circumstances, right? When I've tried that in the past, it sometimes results in too many artifacts (or not enough reduction in some areas) of the image. I guess I've never really grasped the noise-profile concept and how it needs to change from event to event. (3) My typical projects use 4-7 cameras (3-5 different models), and the amount of noise will vary based on how much gain the operator how to apply when shooting in a changing-light environment. When simple options are being displayed, perhaps add a slider control that on one end has "highest quality" and the other end "lower quality/faster-renders" - then, you could behind-the-scenes set the options most appropriate based ont he position of the slider? But this seems somewhat of both an art and a science, and folks like me don't really understand how to disable which options and when it's most appropriate. (2) The NV team has recommended disabling certain noise reduction options to speed up processing (yay!). (1) Examine the clip properties, if possible, to determine if it's interlaced or progressive footage - on a mixed-media timeline it's a nuisance to have to manually remember which clip is which source type and set it when adding the filter, and also prone to users choosing the wrong option seems to be a slower option) it slows to between 1 and 2 frames/sec. With my HD footage and quad core (can't use GPU. I'm a long-time Neat Video client, with the Sony Vegas Pro plug-in - still love the results, but like the rest wish processing speed could somehow be enhanced.
