How to Reduce Noise in DaVinci Resolve: Audio and Video (Step-by-Step)

Noise is one of the most common problems editors face in post-production — but in DaVinci Resolve, “noise” actually refers to two completely different issues handled by two different workspaces. Whether you are dealing with distracting background hiss in your audio or grainy, speckled footage from a low-light shoot, DaVinci Resolve has dedicated tools for both. This guide walks you through each workflow so you can fix the problem, protect your quality, and export with confidence.

Audio Noise vs. Video Noise — Know Which Problem You Have First

Before opening any panel, identify which type of noise you are dealing with. Using the wrong tool wastes time and will not fix your problem.

Audio noise refers to unwanted background sounds captured during recording: hiss from a microphone preamp, low-frequency hum from electrical interference, or ambient room tone bleeding under dialogue. This is fixed inside the Fairlight audio workspace.

Video noise refers to visual grain or color speckle in your image, typically caused by shooting at high ISO or in low-light conditions. This is fixed on the Color page using the Motion Effects panel.

If your footage has both problems, handle audio first in Fairlight, then address video noise on the Color page.

How to Reduce Audio Noise in DaVinci Resolve (Fairlight)?

The Fairlight noise reduction workflow works by sampling a “fingerprint” of your unwanted background noise and then subtracting it from the entire clip. This process takes only a few minutes once you know the steps. All of the following tools are available in the free version of DaVinci Resolve.

Step 1 — Find a Section with Only Background Noise

Before applying any effects, locate a short section of your audio clip that contains only the background noise you want to remove, with no dialogue, music, or other intentional audio layered on top of it. Aim for at least half a second to one full second of isolated noise. This could be a pause before the speaker starts talking, a gap between sentences, or a brief moment of silence at the beginning of a recording.

The quality of this sample directly determines how accurate your noise reduction will be. A clean, uninterrupted noise sample gives the algorithm a precise reference point. A sample that contains even a fragment of speech or music will cause the tool to incorrectly process wanted audio as noise.

Step 2 — Apply the Noise Reduction Effect from the Effects Library

Navigate to the Fairlight workspace by clicking the waveform icon at the bottom of the DaVinci Resolve interface. 

Once inside Fairlight, open the Effects Library panel on the left side of the screen. In DaVinci Resolve 18 and 19, you will find it listed under the FairlightFX category.

Locate Noise Reduction in the effects list, then drag and drop it directly onto your clip in the timeline. The effect will open in its own window. If the window does not appear automatically, double-click the effect applied to the clip to open its controls.

Note: You can also apply this effect to an entire audio track rather than individual clips, which is useful when noise is consistent across multiple recordings made in the same environment.

Step 3 — Sample the Noise Print

With the Noise Reduction window open, position your playhead over the isolated noise section you identified in Step 1. Inside the Noise Reduction controls, click the Learn button (sometimes labeled Auto Detect depending on your version). This instructs the algorithm to analyze the selected audio region and create a noise print: a frequency-specific fingerprint of the background noise floor.

Play through the noise-only section for a moment while the effect is in Learn mode. Once the analysis is complete, the effect stores that profile and will use it to identify and remove matching frequencies throughout the rest of the clip. If your first sample does not produce clean results, try selecting a longer or cleaner noise-only region and resampling.

Step 4 — Adjust Rejection Amount and Threshold

With the noise print captured, you now shape how aggressively the effect applies. These essential controls are:

• Threshold: This setting triggers the noise reduction to start working. It defines a level where softer sounds count as noise. Anything above that level, like voices, stays clear and unchanged.

• Attack: This setting decides how quickly the filter responds after spotting noise. It controls when the reduction begins once the noise is picked up. A quicker attack can catch sharp, sudden sounds, while a slower one keeps things sounding more natural.

• Sensitivity: This setting controls how strong the noise reduction process feels. It decides how it separates noise from the audio you want. Higher values remove more noise, but can cut useful sound. This can make voices sound strange, like an underwater effect.

• Ratio: Once the noise goes past the set level, this setting takes over. It controls how strong the reduction feels at that point. A higher ratio cuts the noise much more than a lower one.

• Smoothing: With this setting, the reduction spreads across a longer time range. It softens how the changes are applied to the audio. This helps avoid sudden shifts and keeps the sound more natural.

• Output: After noise reduction, your track volume can drop slightly. This setting helps bring the level back to normal. It keeps your audio loud enough after the noise gets reduced.

Tips to Avoid Over-Processing Audio

Over-reduction is the most common mistake in audio noise removal. 

Always use the Bypass button in the effect window to toggle the noise reduction on and off while listening. If the processed version sounds worse than the raw audio, dial back the Noise reduction controls in small increments. Aim for the lowest setting that makes the noise inaudible, not the highest setting available. For severe noise problems, using multiple controls at moderate settings often produces better results than applying a single one aggressively.

How to Reduce Video Noise in DaVinci Resolve (Color Page)?

Video noise reduction in DaVinci Resolve lives on the Color page and uses a two-mode system: Spatial and Temporal noise reduction. Understanding what each mode does, and how to combine them without softening your image, is the core skill here.

Open the Motion Effects Panel on the Color Page

Click the Color workspace icon at the bottom of the DaVinci Resolve interface. 

Once on the Color page, look at the row of panel icons running across the top of the viewer area. The Motion Effects panel is represented by a motion blur icon — click it to open the panel on the right side of the screen.

Inside the Motion Effects panel, you will see three main sections at the top. Motion Blur, Spatial NR, and Temporal NR. The Spatial NR and Temporal NR are advanced noise reduction controls you find on the Color Page.

And if you are running the latest Davinci Resolve 21 version, you will notice that the Spatial Threshold section includes dedicated Luma and Chroma controls.

Spatial vs. Temporal Noise Reduction — Which to Use?

Choosing the right mode depends on your footage content and the severity of the noise.

Spatial NR analyzes and reduces noise within a single video frame. It compares neighboring pixels to identify and smooth out random grain patterns. This mode is generally safer for footage with fine texture and detail because it does not reference other frames, which means no risk of motion artifacts.

Temporal NR analyzes a sequence of frames over time, identifying pixels that change randomly from frame to frame (the defining characteristic of noise) and stabilizing them. This produces stronger noise reduction, but it can cause ghosting or smearing on fast-moving subjects if set too aggressively.

For most projects, using both modes at moderate values produces better results than pushing either one to its limit.

Adjusting Luma and Chroma Noise Separately

Both Spatial and Temporal NR give you separate sliders for Luma (brightness-based grain) and Chroma (color speckle) noise. This separation is important because they affect image quality differently.

Chroma noise appears as random color blotches or saturation flicker, and it is usually the most distracting element visually. Chroma NR can be pushed harder without significantly softening the image. Start here first and apply a moderate-to-high value.

Luma noise affects the brightness channel and is closely tied to perceived image sharpness and texture. Pushing Luma NR too high produces a waxy, over-smoothed look that destroys natural skin texture and fine detail. Apply it more conservatively.

A practical starting point: set Chroma NR to around 20–40, then slowly raise Luma NR until grain is reduced without visible detail loss. Preview at 1:1 zoom to accurately judge the effect on fine textures.

Finding the Right Threshold — Avoid Smearing Detail

Start with low Spatial NR values in the 5–10 range and preview the result at 1:1 pixel zoom by right-clicking the viewer and selecting the appropriate zoom level. Look closely at areas with fine detail: skin, fabric, hair, and textured backgrounds. If those areas appear soft, waxy, or plastic, you have gone too far.

For Temporal NR, pay close attention to any clips with significant motion. Play through action sequences or handheld camera movement while Temporal NR is active. If you see a smearing or trailing effect around moving subjects, reduce the Temporal Threshold. If your system supports GPU-accelerated playback, enable it in Playback Preferences to monitor noise reduction results in real time rather than waiting for cache renders.

Pro Tip: Start by pausing on a frame that shows a key area clearly. Zoom in closely, especially on important details like a face. Adjust the sliders while carefully checking the effect on that frame. Once it looks right, play the clip to spot any issues over time.

Advanced Option — Video Noise Reduction in Fusion

If the Color page noise reduction tools are not sufficient for severely degraded footage, DaVinci Resolve’s Fusion compositing workspace offers a node-based alternative. 

Fusion includes the DenoisePro node (available in the paid Studio version), which provides more granular noise control than the Color page panel. To use it, switch to the Fusion workspace, locate the MediaIn node for your clip, and insert a DenoisePro node in the node graph.

For free version users, Fusion still offers basic despeckle and blur nodes that can be combined creatively. This approach requires more compositing knowledge and is best treated as a supplementary fix for specific problem clips rather than a replacement for the standard Color page workflow. Think of Fusion as the option you reach for when the Color page NR has been maximized, and the footage still needs work.

Prevent Audio Noise Before It Reaches Post-Production

The most effective noise reduction strategy is capturing clean audio in the first place. Every fix applied in Fairlight is a correction for something that could have been avoided at the recording stage. Room noise, preamp hiss, and handling noise are far easier to prevent than to remove in post.

Wireless lavalier microphone systems with built-in noise processing have made source-quality improvements accessible for solo creators and run-and-gun shooters. The Hollyland LARK MAX 2, for example, records at 48 kHz with 32-bit Float, which preserves headroom and dynamic range across a wide variety of recording conditions. Its built-in AI Noise Cancellation actively filters background noise at the point of capture, which means less noise enters the timeline to begin with. For creators who regularly deal with noisy interview locations, outdoor shoots, or untreated rooms, investing in cleaner capture hardware significantly reduces or eliminates Fairlight noise reduction work, and the audio quality difference is audible even before post-processing.

FAQs

Does the DaVinci Resolve free version have noise reduction?

Yes. Fairlight audio noise reduction is fully available in the free version of DaVinci Resolve. Video noise reduction on the Color page is also accessible for free users, though certain advanced Temporal NR modes and the Fusion DenoisePro node are limited to DaVinci Resolve Studio.

Why does my audio sound robotic after noise reduction?

This issue appears when noise reduction is set too strongly. So, lower the rejection amount slowly in small steps. Slightly increase the threshold to balance the sound. Use the bypass to compare the clean and original audio. Stop adjusting once the background noise feels less distracting.

Can I apply noise reduction to multiple clips at once in DaVinci Resolve?

For audio, yes. Apply the Noise Reduction effect to the entire track rather than individual clips so that all clips on that track are processed with the same settings. For video, use Gallery Stills or Remote Grades on the Color page to copy and apply your noise reduction settings across multiple clips simultaneously.

What is the difference between Spatial and Temporal NR in DaVinci Resolve?

Spatial NR analyzes a single frame and reduces noise by comparing neighboring pixels, making it safe for detailed footage with the texture you want to preserve. Temporal NR analyzes multiple frames over time for stronger reduction, but risks motion ghosting on fast-moving clips. Use both together at conservative values for the most balanced results.

Conclusion

Noise reduction in DaVinci Resolve follows a clear two-track approach: Fairlight handles audio hiss and hum, and the Color page handles video grain and digital noise. Apply audio fixes first using the Noise Reduction effect in Fairlight, then address video noise via the Motion Effects panel on the Color page using a combination of Spatial and Temporal NR.

Before you export, preview your project at full resolution and toggle your noise reduction settings on and off to confirm you have found the right balance between clean results and preserved detail.
