Fixing crackling noises in DaVinci Resolve - Here's how

If you encounter audio crackling noises while editing your videos in DaVinci Resolve, it can be frustrating. These disturbances often occur when exporting as MP4 and are usually recognizable by high audio peaks. In this guide, I will show you how to fix these issues step by step.

Key Takeaways

• Try launching DaVinci Resolve as an administrator.
• Close unnecessary background programs while rendering.
• Use audio crossfades to smooth transitions.
• Switch the audio codec to Linear PCM.
• Check your microphone settings and connections.
• Use plugin tools for audio cleaning if necessary.

Step-by-Step Guide

Launch DaVinci Resolve as an Administrator

To avoid potential issues, it's recommended to start DaVinci Resolve as an administrator. Right-click on the DaVinci Resolve icon and select "Run as Administrator."

Close Unnecessary Background Programs

When rendering videos, it's important to have only DaVinci Resolve active. Close all other applications to minimize system load. This can help avoid audio errors.

Use Audio Crossfades

When editing your video, add audio crossfades between the clips. Go to the effects library and select the Crossfade +3 dB or 0 dB under "Audio Transitions." Right-click on the selected transition and set it as the default transition. Then press Ctrl + T to apply this transition throughout the timeline. Make sure to remove the transitions at the beginning and end to avoid black frames.

Change the Audio Codec

If the issue persists, changing the audio codec may be helpful. Make sure to export your project in QuickTime format so you can set the codec to Linear PCM under audio settings. This format can improve audio quality and eliminate crackling noises.

Reduce Interference in the Fairlight Section

Switch to the Fairlight section and enable the compressor and limiter for the audio track. Set the limiter to -7 dB to reduce interference. The compressor can help mitigate loud sounds and enhance soft sounds.

Test Different USB Ports

If the crackling persists, test the microphone connection on a different USB port. The current port may be defective. Alternatively, try using a different microphone to see if the issue remains.

Check Your Microphone's Audio Settings

Ensure that your microphone is set to a sampling rate of 48 kHz. To do this, go to the sound settings in your system preferences and select your microphone.

Change the Recording Format

If the issue persists, try experimenting with a different recording format. If you are currently using MP4, consider switching to MOV instead. Sometimes, different formats can affect audio quality.

Use Alternative Recording Software

If nothing works, download and use alternative recording software like Streamlabs OBS to record your videos. The settings are similar to OBS Studio, but the issue may not be replicated with a different program.

Contact DaVinci Resolve Support

If all else fails, do not hesitate to contact DaVinci Resolve Support. The link can be found in the tutorial's video description.

Try out a new editing program

Alternatively, you can try out a different editing program to see if the issue occurs there as well. Sometimes, switching software can help solve the problem.

Summary

In this guide, you have learned how to identify and fix crackling noises in the audio of your DaVinci Resolve projects. With these valuable tips and techniques, you can significantly improve the audio quality of your videos and create a final product free of disturbances.
