How to Add Motion Blur in DaVinci Resolve
Adding motion blur in DaVinci Resolve enhances the realism of movement and can be achieved through various methods, including using built-in effects or Fusion nodes.
Based on the provided reference, one way to add motion blur in DaVinci Resolve involves using the Optical Flow effect, often accessible via a specific workflow.
Here's a general breakdown of how you might apply a motion blur effect, incorporating the reference's key point about Optical Flow:
- Select Your Clip: In the Edit page or Fusion page, select the clip or element you want to apply motion blur to.
- Access Tools: As mentioned in the reference, you might use the space bar to get this select tool bar. This suggests accessing a quick tool or effect palette within your workflow.
- Add Effect: Look for and add an effect or tool related to motion. According to the reference, the first one you're going to add is going to be an optical flow. Click on that; it should bring it into your workspace here.
- Adjust Settings: Once the Optical Flow tool/effect is applied, you will typically need to adjust its settings to control the intensity and appearance of the motion blur. This might involve parameters like "Motion Blur" amount, "Shutter Angle," or "Samples," depending on where you apply the effect (e.g., in Fusion or via an OpenFX effect).
Optical Flow analyzes the movement between frames and generates intermediate frames or motion vectors, which can then be used by the motion blur effect to simulate realistic blur based on the speed and direction of movement.
Alternative Methods (Beyond Reference)
While the reference specifically points to Optical Flow, DaVinci Resolve offers other ways to achieve motion blur:
- Fusion Node Workflow: For more control, you can add motion blur directly within the Fusion page using nodes like the Motion Blur node. This allows for precise control over shutter angle, samples, and quality.
- OpenFX Plugins: Third-party motion blur plugins can also be used.
- Speed Warp (Studio Version): The Speed Warp retime process in the Studio version can generate very realistic motion blur when changing clip speed, as it utilizes advanced optical flow analysis.
Choosing the right method depends on your needs for control, quality, and whether you are using the free or Studio version of DaVinci Resolve. For a quick application, especially when dealing with retiming or slow motion, Optical Flow (as suggested by the reference) is a common starting point.
