Utilize DaVinci Resolve's powerful tools for noise reduction by applying both temporal and spatial methods to video and using the Fairlight page for audio noise reduction. Be mindful of the settings to avoid over-processing, and consider the render in place option for smooth playback, especially with resource-intensive clips.
Before diving into the solutions, it's essential to understand the problem. Noise in video footage can manifest as grainy specks, often more noticeable in darker areas of the frame. This can be due to various reasons, such as high ISO settings, low light, or even the camera's sensor quality. By the way, audio can also have noise, often heard as a hissing or buzzing sound in the background.
DaVinci Resolve offers two primary methods for video noise reduction: Temporal and Spatial. Both have their strengths, and I'd suggest using them in combination for the best results.
Temporal Noise Reduction: This method looks at several frames (usually between 1-5) and compares the noise across them. It's best used for parts of the video without much movement. For instance, if you have a static shot of a landscape, temporal noise reduction might be your best bet. However, on the other hand, if there's a lot of motion in your footage, you might want to tread carefully with this method to avoid unwanted artifacts.
Spatial Noise Reduction: This technique analyzes the pixels in a specific radius to determine what's noise and what isn't. It then smooths out the noise frame by frame. In other words, it's looking at the "space" around each pixel. It's particularly useful for more detailed or textured shots where the noise might be scattered throughout the frame.
To be honest, while both methods are effective, they can be resource-intensive. So, I believe it's often a good idea to apply noise reduction as one of the final steps in your editing process. Furthermore, for those particularly challenging clips, you might as well use the render in place option in DaVinci Resolve to ensure smooth playback.
Noisy audio can be just as distracting as video noise. Let's say you've recorded an interview, but there's a constant hum in the background. How about using DaVinci Resolve's built-in tools to clean it up?
Head over to the Fairlight page in DaVinci Resolve. Here, you can add the Noise Reduction effect to your audio track. If you're feeling a bit overwhelmed with all the settings, simply select the Auto Speech Mode. This mode, as far as I know, does a decent job in most scenarios by automatically reducing the noise. Nevertheless, for more control, you can tweak the Dry/Wet settings to adjust the intensity of the noise reduction.

Noise reduction is an essential skill for any budding video editor. While it might seem daunting at first, with practice and the right tools, you can achieve professional-looking results. DaVinci Resolve, with its robust set of noise reduction tools, offers a great platform to hone this skill. So, all things considered, the next time you're faced with a noisy clip, you'll know just what to do. And if you ever find yourself stuck, there are plenty of tutorials and resources available to guide you along the way.
