Tutorial: Removing Video Noise with the Neat Video Plug-in

In this tutorial, Jan Ozer demonstrates how you can use the Neat Video plug-in to remove noise from video, improving output quality for all outputs.

In this tutorial I'll demonstrate how you can use the Neat Video plug-in to remove noise from video, improving output quality for all outputs.

Shooting in low-light conditions is a reality for most of us. A few weeks ago I shot a speech by Democratic congressional candidate Anthony Flaccavento at a local incubator facility, and as you can see in Figure 1 (below) and in the video above, there's lots of noise in the background, and even on the candidate's face. That's because I had to boost gain to achieve the proper exposure.

Applying the Neat Video Filter

Fortunately, gain-related noise—which is very common, and precisely the problem we're dealing with here—is exactly what the Neat Video filter was designed to correct. By way of background, the filter, which you can find by Googling "Neat Video filter," starts at about $50. It supports popular pro NLEs like Premiere Pro, Final Cut Pro (including FCP X), and Vegas (as well as Adobe After Effects).

Once you've purchased and installed the plug-in for your NLE of choice, you apply it to the clip as you would any other included or installed filter. Figure 2 (below) shows how it's selected in Premiere Pro CS6.

Creating a Noise Profile

Then you click the Settings button (Figure 3, below), which brings up a full-screen view.

If you've worked with video that you've created a profile for in the past, click the Load Profile button (Figure 4, below) to load the profile. When you have a number of clips that have the same noise issues, saving a profile—as with audio noise—allows you to save and later reload a noise file from a comparable clip.

If it's the first time you've worked with a particular video, click Auto Profile instead (to the left of the Load Profile button in Figure 4, above). This tells the Neat Video filter to scan for an area in the image that's flat and has little detail, and thus is a region where it's easy to tell whether the changes it detects between frames are noise, or true motion in the frame. In the section of the frame shown in Figure 5 (below), there's no true motion, so all the motion relates to noise that the filter will attempt to eliminate.

Over on the right you'll see the Device Noise Profile settings for the clip (Figure 6, below). Here it's key to make sure that the quality setting is over 60, which means that the filter found a region that will enable it to accurately discriminate between noise and motion.

If you don't have a flat region in the video—if all your video looked like the section of the image highlighted in Figure 7 (below)—then you'll have to set some of the original noise-related settings manually. We'll look at how to do that a bit later.
