Join Richard Harrington for an in-depth discussion in this video Using Neat Video, part of Fixing Video Exposure Problems in Premiere Pro CC.
Another popular plug in for noise reduction is the Neat Video plug in. This works in a similar way to the Red Giant tools. Let's take a look at a shot here. It's got a little bit of noise in the region, and under Effects I'll apply the Reduce Noise Effect. You'll see that this has the ability to make a few adjustments, although not as many as you had in the other plugin. Let's open up the Setup window and tell it to create an auto profile.
We'll tell it to use this existing area. You'll also note you have the ability to manually load profiles if you've created them for cameras earlier. Taking a look at the filter settings here, you could adjust how much noise is available. Luminance and chrominance to go through and remove noise, mainly in the dark areas. And I'll reduce the amount of color noise so it's not as intense. You also could apply some sharpening to the shot to put a little bit of the detail back in. Clicking the Preview and Filter button, you could toggle the results in between. This clip is relatively clean, but it definitely looks better.
And it's a lot easier to see this viewing at 100%. Particularly looking at the sweatshirt here, you can see some of the noise in there, and once applied, it's done a nice job of cleaning that up. But I'll put a little sharpening back in to put some of the details in the folds of the fabric. That looks good and I'll click Apply to add it. The filter has been applied and let's zoom into 100% and you can definitely see that some of the noisy areas in that sweatshirt have been cleaned up.
In fact, looking at the vector scope, you can see it also pulled down. Some of those darkest, noisiest bits. And it's affecting the video signal. But looks pretty good. We'll select the clip, and choose Render Selection. And you see it does render pretty quickly, which is why this is one of the most popular noise reduction filters. When it comes to noise reduction, this is something I'd like to avoid. That's why I spend so much time in the field trying to get it right. Remember, it's okay to have subtle bits of noise, and when you do your final video compressions, you can actually apply a bit of a Gaussian blur to those outputs as well as part of the media encoder, or the other compression tools' software process.
But find a balance and decide where you're going to reduce noise and I always recommend starting when you shoot the video in the first place.
