[Tutorial]How to Denoise Footage in DaVinci Resolve

If you want your videos to seem professional, you need to get rid of the distracting background noise. Most amateur video creators have to make do with low-quality equipment like DSLR cameras or smartphones, while professionals may afford to utilize advanced audio recording techniques and technology to minimize ambient noise.

Thankfully, DaVinci Resolve denoise provides powerful built-in tools to reduce unwanted background noise and improve your audio quality. In this tutorial, we’ll walk through the steps for effectively denoising your clips using Resolve's noise reduction filter. With just a few simple tweaks, you can make your footage sound clean and crisp. Let's learn how to denoise footage in DaVinci Resolve.

Part 1. What is Background Noise?

The first step in getting rid of noise is finding out where it's coming from. Audio background noise refers to any unintentional noises picked up by the microphone that distract from or otherwise confuse the primary audio information.

Ambient noise can come from a variety of sources, such as a computer fan, traffic, wind, vents, or even a microphone. Even minor noises can become gratingly annoying when amplified and mixed with other auditory features.

Excessive background noise gives your video an unprofessional, amateurish feel. It can make dialogue difficult to understand, force viewers to turn up their volume, and generally detract from the viewing experience. Background noise seriously affects the viewer’s video experience. But, DaVinci Resolve remove background noise feature can help.

Part 2. What is a DaVinci Resolve Audio Noise Reduction

Built right into Resolve is an advanced noise reduction filter designed to clean up your audio. It analyzes the clip to identify patterns of noise vs actual audio content.

The filter works by isolating and targeting just the frequencies where the noise lives. You can then turn down the volume on just the noise without affecting the rest of the sound.

It's like a surgeon carefully removing cancer cells without damaging healthy tissue. When used right, the filter makes noisy audio sound nearly as good as a studio recording.

The DaVinci Resolve noise reduction filter is highly customizable, allowing you to tweak settings like noise floor reduction, recovery speed, and frequency cutoff points. This gives you surgical-like precision to target the noise in your clip without introducing artifacts. Used properly, it can make noisy audio sound nearly as clean as if it was recorded in controlled studio conditions.

Part 3. How to Denoise Footage in DaVinci Resolve?

Here is how to remove background noise in DaVinci Resolve:

Step 1: Open Fairlight and Add the Noise Reduction Filter

First, open up the Fairlight page in Resolve and locate the Audio Effects folder in the Mixer window. Click on Noise Reduction, then double-click on the Noise Reduction filter to add it to your audio track. This will open up the filter's parameter controls.

Step 2: Understand the Layout and Controls

The DaVinci Resolve 18 remove background noise filter has various settings and meters across the top and bottom. Key controls include the preset selector, the A/B comparison slots, the main On/Off toggle, and the Listen to Noise Only solo button. The input and output meters let you monitor volume levels before and after filtering. The center graph shows which frequencies are being targeted.

Step 3: Set the Detection Parameters

The detection settings determine how the filter analyzes the noise in your clip. Threshold adjusts the signal-to-noise ratio detection sensitivity. Attack controls how quickly the filter reacts to changes in noise over time. Sensitivity tweaks how responsive the filter is to the target noise frequency range. The ratio affects the attack time relative to the learned noise profile.

Step 4: Adjust Smoothing to Reduce Artifacts

The Frequency smoothing setting can help reduce audible artifacts like harmonic ringing that may occur as a side effect of the noise reduction. Use sparingly or disable if not needed.

Step 5: Dial in the Reduction with the Output Controls

The Dry/Wet mix knob lets you blend between the filtered and unfiltered signal to taste. The Level fader compensates for any volume loss from the reduction. Listen critically as you adjust these output controls to find the optimal balance of noise reduction for your clip.
