MotionBlur
Motion-estimated temporal blur
Estimates movement between frames and adds directional blur that mimics camera shutter exposure.
MotionBlur
DaVinci Resolve · Fusion
MotionBlur analyzes frame-to-frame movement and smears moving detail along the estimated direction, helping CG and graphic motion feel less mechanically sharp.
Overview
What MotionBlur does
MotionBlur is different from a simple directional blur because the blur direction can vary across the image according to estimated motion.
Motion-estimation quality and range determine how much work Fusion performs to understand movement. Faster settings are cheaper, while Better and larger ranges can help more complex movement at additional cost.
As with optical-flow tools, intersections, occlusion, transparency, flashes and fine texture can generate artifacts. Always evaluate the actual moving shot.
Mental model
Think of MotionBlur as estimating where pixels traveled during the exposure and spreading them along that path.
Common uses
Soften animated graphics
Add shutter-like blur to fast motion
Blend CG movement into live-action footage
Reduce strobing in sharp animation
Stylize fast transitions

Important parameters
Start with these controls before reaching for more complicated workarounds.
Mo. Est. Type: None
Uses None for mo. est. type.
Mo. Est. Type: Faster
Uses Faster for mo. est. type.
Mo. Est. Type: Better
Uses Better for mo. est. type.
Motion Range
Defines the expected movement distance.
Use Small for subtle movement and increase only when objects travel farther between frames.
Motion Range: Small
Sets Motion Range to Small.
Motion Range: Medium
Sets Motion Range to Medium.
Motion Range: Large
Sets Motion Range to Large.
Motion Blur
Controls blur strength or shutter-like amount.
Start modestly; too much blur quickly destroys detail.
Blur Direction
Controls whether blur extends from the previous frame or around the current frame.
The correct choice depends on the visual style and timing relationship.
Blur Direction: From Previous Frame
Sets Blur Direction to From Previous Frame.
Blur Direction: Both Directions
Sets Blur Direction to Both Directions.
Blur Direction: Towards Next Frame
Sets Blur Direction to Towards Next Frame.
Granularity
Sets how finely motion is subdivided when the blur is calculated.
Practical setup
A reliable workflow
- 1
Connect a clean version of the moving source.
- 2
Choose a motion-estimation quality.
- 3
Set Motion Range to match the shot.
- 4
Increase Motion Blur gradually.
- 5
Inspect silhouettes, crossings and semi-transparent edges.

Troubleshooting
Common mistakes
Choosing a huge Motion Range for a shot that does not need it.
Judging quality on a still frame instead of playback.
Applying motion estimation after heavy noise or grain.
Ignoring warped edges at occlusions.
Production notes
Practical tips
Apply grain after motion estimation when possible.
If the motion is simple and uniform, DirectionalBlur may be cheaper and cleaner.
Use the smallest motion range that reliably tracks the movement.
