Grainy video at DVinfo.net

I was given some 'grainy'raw footage which I want to clear up. I have both FCP3 and Premiere. Any suggestions?

Thanks,
KP

What is it shot on DV, analog?

It was shot with a Canon Gl-2

In FCP, go to Effects>Video Filters>Image Control. I've had limited success working with brightness and contrast, as well as adjusting levels. I've also used Gaussian Blur with limited success.. The 3 way Color Corrector may also be of limited use. Small adjustments have the best effect. Large dramatic changes often make the images unusable. As you can probably tell, fixing grainy images is not easy and no one filter makes the image perfect. Experimentation may give you an image that proves acceptable.

I am not familiar with FCP or Premiere, but maybe look for "frame averaging". If there is not too much (fast) motion in the image you can significantly reduce noise. Even better, and used in some pro cams and medical (ultrasound) and Defence equips is motion adaptive averaging. An example (for a still image) of this powerfull temporal averaging technique can be found here http://www.nlectc.org/assistance/frameaveraging.html

There's a plugin called Grain Surgery that is supposed to do wonders. I've never used it. There's a downloadable demo. It's 400 bucks, though. It plugs into After Effects, Final Cut, Commotion, and Avid X DV. You could call around to effects houses in your area and see if you could rent time or pay for their services. Might be cheaper than buying the plugin.
