Remove Noise from Canon ZR850
1 Attachment(s)
I have a Canon ZR850, which is notorious for bad, bad, REALLY bad low light noise. I have Sony Vegas 7, the newest release, and an assortment of plugins.
The noise is almost acceptable on a normal CRT, but if I watch the clips on an LCD with even the smallest amount of sharpening, it looks like a snowstorm. Is there a good filter or process I could use to fix some of that noise? You know, in Photoshop CS2 and CS3 there are some POWERFUL noise reduction tools. I assume those filters can work with Adobe's NLE, but as I have Vegas, that's moot. I'm attaching a sample of the extreme noise. Actually looks a lot better on the monitor than on a television. What do you think? DJ Kinney |
A few users here and on other Vegas forums have been highly recommending the noise reduction plug-in from Neat Video.
A trial version is available. |
Neat Video 'Home Version', as they rather unwisely call it, is just $49, and the single difference from the Pro version (that affects Vegas users) is that you can only filter noise from an area up to 720 x 576 pixels (which is fine if you are working in SD). The Pro version is unlimited size therefore suited to HD editors.
I have downloaded the demo (for After Effects, actually, but I guess it uses the same engine) and it is very impressive, even the presets return great results. While typing this I downloaded the Vegas demo and had a very quick play. Seems to be just as impressive. I hear the creaking of plastic . . . http://www.neatvideo.com/index.html Ian . . . |

Holy $#!t! I've attached a sample of the NeatVideo filter. It's really quite unbelievable. The render time is atrocious, but I suppose it's a trade. I've rarely been this impressed by a filter. Wow.

Wow! I'm sold! That gets it down to the point that the blacks can be crushed into being noiseless and the subject and background objects look very clean. Am I wrong in saying that this could make 12db of gain look like no gain was used? That would be a miracle for some footage.

Wow again. As much as I like the cleanup of the blacks, the skintones look like a good makeup artist caked on a nice coat of spackle. Outstanding. Marcus, I agree, 12db with aplomb (well, it needs some testing).

I too am really impressed with this filter. My wife used a Sony HC96 and was at 15 db gain most of the time so I thought it would be a good test of the filter to clean up. The render time in Premiere was about 8 times realtime with my X2 4200 but the results were matched to my FX1 at 6db very well. I shall certainly get this for the few occations that I need to clean up some video. Just out of interest I ran a short test with FX1 clip and the result was wonderful clean image. All was using the pressets so I am sure a little more effort would yeild even better results. I like the fact that one can create a noise image for a camera and save as preset.

Seriously though, that plug-in looks great. I'm going to chase it down. -gb- |
