How to Remove Background Noise in Davinci Resolve? If you’ve ever captured a video in low light or recorded sound with a fairly poor microphone in a difficult environment, you’ll be familiar with video and audio noise and how hard it is to remove it. Fortunately, DaVinci Resolve includes some excellent tools for effectively reducing noise in both video and audio.
How to Remove Background Noise in Davinci Resolve?
- Click the “Effects” tab (previously known as “Effects Library”) on the “Edit” page.
- Select “Audio FX” > “Fairlight FX” from the left-hand menu.
- Track down the “Noise Reduction” effect.
- Drag and drop the effect onto the timeline above your desired audio clip.
- Choose “Manual” and then “Learn”. The button needs to be highlighted.
- Move your playhead to the unnecessary sound, such as wind or rumble.
- Stop after playing the audio clip with only noise.
- Resolve has now mastered the noise print.
- Click on “Learn” so that it is no longer highlighted.
- Play the audio clip now. There should be no conflict (like wind).
The “Learn” section of Resolve is critical for effective noise removal. If the noise is correctly learned, it can be easily removed.
How to Make a DaVinci Resolve Audio Noise Reduction Preset
Presets are a convenient way to save your noise reduction settings for upcoming use, especially if you anticipate similar background noise in future DaVinci Resolve projects. To make a preset, go through the following steps:
- Tap the “+” tab to open the “Noise Reduction” plugin. This means “Add Preset”.
- Select the name you want to save it as.
- By selecting OK, you can save the preset.
To utilize the preset in the future, simply drag and drop it from the drop-down menu onto your audio clip or track.
When you have several videos in your timeline with similar background noise profiles, you can speed up your work by applying your plug-in to the entire track rather than individual videos.
This is accomplished by simply dragging and dropping the plug-in onto the track header as opposed to a single clip.
Davinci Resolve plugins are relatively easy to install and use, so I am confident you will be fine with them. Now, let’s go over how to add Plugins.
How to Add a Noise Reduction Plugin to a Track in Fairlight
- Select the “Fairlight” tab.
- To access your audio track, click the “Mixer” button.
- After you’ve accessed your track, open Effects and click the “+” sign.
- Click “Noise Reduction,” then select “Noise Reduction” again from the options.
- The noise reduction effect will be implemented immediately.
Video Noise Reduction
Video noise is a different beast, but DaVinci Resolve also has a solution for it. In DaVinci Resolve, video noise reduction is performed on the Color page. It can, however, be done as an after-effect during post-production on the Edit page.
To eliminate background noise from a video, do the following:
- From the Open FX panel, choose the video noise reduction effect.
- Drag the effect to the node or video that is highlighted.
- This can also be done via the Color page’s Motion Effects panel.
Whatever approach you take to video noise reduction, you’ll come across two options: temporal noise reduction and spatial noise reduction. They work on different parts of your clips and can be used separately or together.
Temporal Noise Reduction
The frames are protected, and their noise patterns are compared side by side in this method. It works best for portions of an image that have little or no movement.
It is a little challenging on your system, but it produces better results than spatial noise reduction. You can change the threshold to specify how much temporal noise reduction you want.
Spatial Noise Reduction
The pixels of a frame section is analyzed in spatial noise reduction. The noisy parts are distinguished from the noiseless parts, and this information is then applied to subsequent frames.
To better eliminate noise, there are customizable Mode and Radius settings that can be utilized to edit the intensity and threshold of the effect.
DaVinci Resolve Noise Reduction Settings
Auto Speech Mode – Use this option when you have a conversation. Resolve will automatically “learn” and remove the noise. If you’re not pleased with the noise removal, experiment with different settings such as “Threshold”, “Attack”, “Sensitivity”, and so on.
The “Dry/Wet” and “Level” knobs are located in the “Output” section. Using the “Dry/Wet” knob, you can reduce or increase the output of the noise removal methods described above.
“Level” – If your audio dB level has been reduced due to noise reduction, use the “Level” knob to raise the dB level (output gain).
To see the difference between before and after, toggle the “Noise Reduction” button on and off. The button is located in the upper left corner.
(When working with this effect, you may need to play the audio in a loop to correctly recognize and eliminate the noise.)
The preceding description is for a single audio clip. You must create a preset if you want to utilize the same noise reduction settings for multiple clips.
In Fairlight Resolve, how do you apply a noise reduction effect to a track?
- Navigate to the “Fairlight” page.
- Tap on “Mixer,” and your audio track should appear.
- Tap the “+” plus sign next to “Effect” under your track.
- “Restoration” > “Noise Reduction” should be selected.
- This noise reduction effect will be applied throughout the track.
Furthermore, within Fairlight, you can apply noise reduction effects to specific videos and save them as presets.
Other effects can be used to eliminate noises, such as power line hums or low rumbles within a room. Some significant audio effects are:
- Dialogue Processor,
- De-Esser, etc.
How to Eliminate Hum Noise in DaVinci Resolve
The “De-Hummer” effect, which can be found under the “Effects” tab on the “Edit” page, can be used to remove hum noise.
- Tap the “Effects” tab in the upper left section of the “Edit” page.
- Select “Audio FX” > “Fairlight FX” from the drop-down menu.
- Identify the “De-Hummer” effect.
- Drag the effect onto the desired audio clip.
You can experiment with the “Frequency” and “Amount” knobs until the hum is gone.
The frequency of hum on power lines in the United States is 60 hertz, while it is 50 hertz in Europe. As a result, you should choose the right radio button under “Frequency” for a much better outcome. If not, you can always change the knob to meet your needs.
How to Eliminate Low Rumble Noise in DaVinci Resolve?
The “Equalizer” effect is very effective at removing low-frequency rumble noise. A high-pass filter (band 1) should be able to cut out the low-end frequencies while leaving other frequencies alone.
- Navigate to the “Fairlight” page.
- Tap on “Mixer,” and your audio track should appear.
- Double-click on the graph next to “EQ” in your track.
- The “Equalizer” plugin will appear.
- “Band 1” should be selected.
- Play the video. If the noise is deleted, you are good to go.
- If not, modify the frequency knob so that the EQ captures and eliminates the low-frequency noise.
- Raise the gain (on the right-hand side of the plugin) if necessary to compensate for any sound reduction caused by EQ processing.
You can also use Equalizer to eliminate high-frequency hiss sounds. All you need to do is use a low-pass filter (Band 6). The higher frequencies will be removed by this low-pass filter (hiss sound).
Getting Your Environment Ready for Audio Recording
The best way to eliminate background noise is to avoid it altogether, and there is no better way to do so than by properly preparing your recording space or room. To reduce reverb and low ambient noises, use acoustic foams and sound-absorbing panels.
Using the proper recording equipment is also important. This, however, does not guarantee noise-free audio.
Unwanted noise is unavoidable, and knowing how to deal with it is essential. You may not be able to remove all of the noise, but with the right effects and adjustments, you can help minimize the noise in DaVinci Resolve.
Noise in audio or video can degrade the quality of your finished video and be difficult to remove. Fortunately, DaVinci Resolve’s built-in noise reduction tools for video and audio will assist you in eliminating the noise. Now that you’ve saved this helpful tutorial, you can effectively reduce and fix any static noise issues in your video and audio recordings.
