Reactor – An Audio Visualizer Plug-in in DaVinci Resolve 17

How to Create an Audio Visualizer in DaVinci Resolve

If you’re anything like me, you may miss the old days of listening to your music on WinAmp to its impressive collection of audio visualizer effects. While it remains true that, for the most part, audio visualizers have fallen out of style for everyday users, they still have a use today for those of us who create video content on YouTube. Particularly for intros and for tailored VFX B-Roll content.

Say, for example, you want to make your channel logo dance in the corner of your screen for the accompanying background music for your intro. Rather than try to manually create this, you can use a plug-in tool called Reactor in DaVinci Resolve 17, and your logo will pulse to the beat.

Before I get too deep into this article, I wanted to put this out there – This post is designed to do two things:

  1. Inform you about the existence of the tool
  2. To reference quality tutorials that are easy to follow to achieve the Audio Visualizer effect for your video content.

This is because a video tutorial format is superior for teaching you how to use the Audio Visualizer effect.

Addressing the… Stuffed Animal In The Room

Reactor, the DaVinci Resolve Fusion plug-in you need to create an Audio visualizer effect out of an image is by a Blackmagic Fusion Studio Community who calls themselves “We Suck Less.

Now, I know what you’re thinking – A tool designed by a community that calls themselves “We Suck Less” with a muppet mascot as their defining logo feature on a shady-looking forum screams of a scam. Or, at the very least, a virus. However, I’ve looked through YouTube, across multiple videos that answer this question in a tutorial format (for my own learning and for validation of the tool), and found nothing that really stood out to me as being potentially dangerous.

In fact, most videos show proof of it functioning properly.

But a quick disclaimer, I can not guarantee the tool to be virus or malware-free – The script itself is in LUA. However, I don’t understand that language well enough to understand everything it is doing when opening it in notepad++. What I do know is that there is a reference to a private Git within this install script, in the form of downloading files from a private repo on Gitlab. I couldn’t find a link to the git repo itself on their website anywhere. (Not to say it isn’t there, I just couldn’t find it.)

Video Guides By Multiple Creators to Validate the Tool

The following links in the list are tutorials on using the Reactor plug-in tool and the validation that convinced me the tool was safe enough to write about. Additionally, I think that a video format tutorial is superior for teaching you how to use the tool itself, as a written guide for this subject simply isn’t as easy to follow. That said, a written guide follows for those who prefer that format.

Consider subscribing to these creators if you intend to learn more about DaVinci Resolve for yourself.

These videos were created for DaVinci Resolve 16; however, this tool still works without issue in DaVinci Resolve 17. There are many other tutorials by other creators about this tool on YouTube as well, so if you need more guidance, it is merely a quick search away.

How to Use Reactor

  1. Switch to Edit Mode
DaVinci Resolve 17 Edit Mode
  1. In your toolbox, select Effects, and drag the Fusion Composition Clip to your timeline (away from your existing project clips)
Blank Fusion Composition Clip
  1. Select the Fusion Composition Clip (It will have a red outline when selected)
  2. Right-click the clip, and select “Open in Fusion Page”
Open in Fusion Page
  1. Open the Media Pool Tab
  2. Select your logo, and drag it into the node area

  3. Select the logo Node, and Add a Transform tool
Transform Tool

  2. Select the Transform Node
  3. Open the Inspector
Inspector tool in DaVinci Resolve 17
  1. Locate “Size” and right click it
  2. Hover over “Modify with” and select “Audio (WAV)”
Modify With Audio (WAV)
  1. Select Modifiers
Select Modifiers
  1. Choose the wav file you want it to react to. It needs to be 16 bit PCM as well for the tool to work.
    • If online converters are not giving you the proper setting, you can use the Reaper DAW to convert the audio file manually to 16 bit PCM WAV.
Wrong Bit Depth
  1. Play with the settings here. Avoid Time offset unless you know what you’re doing, as it makes it hard to line the audio up with the visualizer.
  2. Put the audio track in below the Fusion Composite Clip to have the audio play back in video.
  3. Profit!

Whew! That was a long list of steps. But, again, I feel that a video format tutorial is far better for this sort of thing, so if you haven’t yet looked at one of those I listed above, I recommend doing so if you’re lost on one of these steps. I hope that this little tutorial was helpful for you nonetheless.
