Quickly Adding Motion Blur in DaVinci Resolve: A Step-by-Step Guide

What You’ll Be Creating


Motion blur is a critical aspect of video editing. It can enhance the visual quality and realism of your footage. It replicates the natural blurring effect our eyes perceive when objects move. It provides a sense of speed and fluidity. Knowing how to add motion blur in DaVinci Resolve can elevate your editing skills and final product. There are two main ways to accomplish this task. The first uses Optical Flow and Vector Motion, and can be accomplished with the free version. The second method is a little more complex, but provides better results. It uses Motion Blur Ramping, but can only be completed with a paid for version of DaVinci. Both methods start with the same step. Import your video clip and drag it into your timeline.

Method 1: Using Optical Flow and Vector Motion Blur

The method involves using two features in DaVinci Resolve. Optical Flow and Vector Motion Blur. For this tutorial, we’ll use a clip of a video I created for another article (How to Create AI Music Videos With AI Art Generator Kaiber). This method applies to any video type you may want to use. If you’re looking for diverse footage to practice on, consider checking out Envato Elements. Envato Elements offers unlimited downloads of high-quality stock videos. Here’s a step-by-step guide:

Step 1: Navigate to the “Fusion” tab at the bottom of the screen.

Step 2: Press ‘Shift and Space’ simultaneously to bring up the search menu.

Step 3: Type “Optical Flow” into the search bar, select it, then click ‘Add’ button.

Step 4: Without adjusting the Optic Flow settings, press ‘Shift and Space’ to bring up the search menu again.

Step 5: This time, type “Motion Blur” into the search bar. Select “Vector Motion Blur”. Click “Vector Motion Blur”, and then click ‘Add’ button.

Step 6: Once you’ve added Vector Motion Blur, you can adjust the intensity by adjusting the ‘scale’ slider. For instance, setting it to 10 will create an extremely blurred effect. In contrast, setting it to 0 will make the motion blur non-existent. For subtle and clean motion blur, a setting of around 0.33 should work pretty well. In my case, the video I’m working with looks better with more.

Method 2: Using Motion Blur Ramping in DaVinci Resolve

The motion blur ramping method allows for a little more focused motion blur giving your effect a deeper and more realistic feel, as opposed to the first method which is a little more broadly applied. It has a few more steps involved but can be really impactful, especially when adding sounds to go along with it. Here’s a step-by-step guide:

Step 1: “Right Click” on your clip and chose ‘Retime Controls’. You can also press ‘Ctrl+R’

Step 2: Use your pointer to drag the timeline marker to the point where you want the motion blur to start.

Step 3: Click on drop down arrow on your clip, and choose ‘add speed Point’.

Step 4: Repeat steps 1 and 2, for the end of the effect. Find the point where you want the blur to END, and add a speed point there too.

Step 5: Click, hold the small red arrow above your preselected end point you selected in your earlier step, and drag it towards your starting point. This will increase the overall speed of that particular section. You’ll want to speed it up to about 450%, depending on the look you’re going for.

Step 6: Right click on clip and choose ‘Retime Curve’.

Step 7: Click the ‘Drop Down’ arrow, and turn off ‘Retime Frame’ by unchecking the box. Then check the box next to ‘Retime Speed’ to turn it on.

Step 8: Now the effect changes are applied we need to smooth everything out a bit to make it ramp up versus step up. To do this, click on the left ‘key-frame’, then click the ‘smooth’ button. Then repeat the process for the other one.

Step 9: Now use the ‘handles’ to adjust the curves of the keyframes. You can really smooth the curves to get a nice speed ramp.

Step 10: Once you get done perfecting the smoothness of your curves, you can go ahead and turn OFF your ‘retime curve’ by using your ‘Right Click’ menu on your clip.

Step 11: Click on ‘Effects Library’, then click on small square left sidebar, at the top left hand corner. This will show you all the different categories you have to choose from. Click on ‘OpenFX’, then click on, hold, and drag ‘Directional Blur’ down to to your clip.

Step 12: Click on ‘Inspector’, then click on ‘OpenFX’. This is where we’ll decide which way we want our blur direction to move. The easiest way to test to make sure your direction is correct is to turn your blur strength all the way up. Don’t worry, we’ll turn it back down, but we just want to do this to check to make sure the motion direction is correct.

Step 13: Use the ‘Blur Angle’ slider to adjust the blur angle.

Step 14: Often times in editing you’ll want to get rid of the black border, to do this, use the ‘Border Type’ drop down menu and choose ‘Replicate’.

Step 15: Once you’ve got everything looking good, now you can adjust your blur strength down to zero, then refer to your timeline and after placing your playhead on your first speedpoint move back four frames using your ‘Left Arrow’.

Step 16: Add your first keyframe under ‘blur strength’ by clicking the diamond button in the ‘OpenFX’ tab. Make sure the blur strength is set to zero for the first keyframe.
