In this tutorial, we'll show you how you can add realistic motion blur and gaussian blur to your videos in the free version of DaVinci Resolve 17 and beyond!
Motion blur is a visual effect used in videos to simulate the natural blurring of a high shutter angle camera that occurs when an object or camera moves rapidly. It is used to create the illusion of movement and to make fast-moving objects appear more realistic. Motion blur can be applied to individual elements in a video, such as a moving car or a running person in the foreground, or to the entire image, such as when panning the camera. It is achieved by taking multiple frames of the same object or scene and blending them together, creating the illusion of motion. In video editing softwares such as DaVinci Resolve, motion blur can be applied using various tools, such as blur filters and can be customized with keyframe animation.
Adding motion blur to your videos can make your video look more realistic. It also helps with transitions, making them flow better by hiding the seam more effectively. If used correctly, motion blur can also add depth to your video.
Contrary to popular belief, it's actually possible to add a high quality, After Effects style motion blur to videos in DaVinci Resolve. To do so, start off by animation some aggressive movement onto your clip. This can be anything like a zoom transition or a quick camera pan. Here's how we did it:
Next, we just keyframed some scale animation. Once we finished our animation, all we had to do was increase the motion blur value to anything above 1 (found under the advanced options tab).

In DaVinci Resolve, the strength and direction of motion blur can be adjusted using the "Blur" effect, which can be found in the "Effects Library" under the "Transform" category.
To adjust the strength of the motion blur, you can use the "Blur Length" parameter. This will control the length of the blur trail, with higher values resulting in stronger blur.
To adjust the direction of the motion blur, you can use the "Angle" parameter. This will control the direction of the blur trail, with positive values creating a blur in one direction and negative values creating a blur in the opposite direction.
You can also use the "Blur Center" parameter to control the center point of the blur.
It's also possible to use keyframe animation to control the strength and direction of motion blur over time. This allows you to create more dynamic and nuanced motion blur effects, such as having the blur strength increase or decrease over the course of a shot.
Additionally, you can use the "Transform" effect to simulate motion blur by adjusting the position, rotation, and scale of a clip over time. This allows you to create more realistic motion blur effects that take into account the movement of the camera and objects in the scene.
You may increase and decrease the prominence of your motion blur effect along your timeline if you want certain times to have more or less motion blur.
This can be done easily with keyframes, the same way you'd use them to animate a zoom transition or anything else.
As we mentioned above, motion blur is best used with sudden strong movements in your video. Combining motion blur over a transition is a recipe for a professional-looking video as it create a realistic atmosphere in your shot.
