Motion Blur (Studio Version Only)
This effect replicates the Motion Blur panel in the Color page’s Motion Effects palette. The Resolve FX version allows you to use these tools across the other pages in the program. Motion Blur settings use optical flow-based motion estimation to add artificial motion blur to clips that have none. This can be useful in cases where a program was shot using a fast shutter speed, and you later decide that the resulting video has too much strobing. By analyzing the motion within a clip, the Motion Blur settings can selectively apply blurring to the image based on the speed and direction of each moving element within the scene.
Three parameters let you set how much motion blur to add, and at what quality:
— Motion Est. Type: A setting of Better provides more accurate pixel mapping at the expense of being more processor intensive. Faster provides a more approximate result but is less processor intensive.
— Motion Range: Determines what speed of motion to consider when defining regions being blurred.
— Motion Blur: Raise this parameter to add more motion blur to the image, lower it to add less. The range is 0–100, where 0 applies no motion blur, and 100 applies maximum motion blur.
— Blur Direction: Allows you to chose which way the blur extends from the current frame. The options are: Both Directions, From Previous Frame, and Towards Next Frame.
— Granularity: Adjusts how much detail is added to the blur.
Motion Trails (Studio Version Only)
The Motion Trails effect copies the image to create ghost-like trails on moving images. This effect can be used to simulate clips shot with long shutter speeds and analog video feedback effects.
General
The first two sliders control the number and strength of the copied frames.
— Trail Length: Determines the number of copies that are used to create the trails.
— Dropoff: Sets the fade applied to each copied frame. The Dropoff value is compounded.
For instance, using a value of .5 applies 50% opacity to the first copy, 25% to the second, 12.5% to the third, and so on.
Advanced Options
The advanced options are used to control how the overlapping copied frames are blended.
— Composite Gamma: The Composite Gamma menu provides four options for controlling the brightness of the overlapping frames.
— Timeline: Uses the Timeline Color Space setting in the Project Settings to control the overlapping brightness. This setting, by default, is Rec. 709, Gamma 2.4.
