EXPOSURE BLUR

Presets

If you need a flash of inspiration in applying Exposure Blur to transition between your clips, our one-click presets have you covered. Simply keyframe the Mix duration (see below) and tune to taste! Find these presets via the blue Open Dashboard... button or the Choose a Preset... button below it.

As with all other Universe tools, you can modify or create an Exposure Blur look and then save it under its own name by pressing the Save Preset... button.

Getting Started in a Timeline

1. Drag the transition over your edit in the timeline, placing it at the end or beginning. Alternatively, you can place it between two successive clips.
2. Modify the Duration of the transition either by entering a length in the field or dragging directly in the timeline.
3. You can choose the Alignment (Center at Cut, Start at Cut, End at Cut, or Custom Start) either by positioning the transition in the timeline or by choosing from the Alignment drop-down in some host applications.

Getting Started in a Compositor

1. Apply the transition to the layer from which you want to transition.
2. Choose the footage layer you would like to transition to in the Transition B drop-down menu. (Note for Motion users: Drag the footage layer up to the Transition B box.)
3. Animate your transition using the Mix slider from 0% to 100 percent. Set a keyframe for 0% where the transition should start, then set another at 100% for the end.

Modify the Transition

• Exposure sets how bright the transition will get. Below, we offer the half-way point through the transition shown in the animation atop this page. We show values of 2.00 (the default, left), 0.5 (center), and 8 (the maximum, right).
  
• Blur
  • Check the Proportional box if you want the horizontal and vertical blur levels to change in tandem. Then use the Blur slider to set the level for your blur. As a reference, here's the difference between values of 0.25 (left) and 1.5 (right).
    
    
  • If you uncheck Proportional, then you can use the Vertical Blur and Horizontal Blur to set each direction of the effect independently. For reference, here's our base image with Proportional unchecked (left) followed by a Vertical Blur of 3 (center), then a Horizontal Blur of 6 (right).
    
  • Zoom Blur sets a blur effect that moves out in z space. In this example, we use the Zoom Blur preset to show a parameter value of 30.
    
• The Dolly slider lets you move the camera a bit closer in along the z axis toward the B-clip layer. To illustrate, here are values of 0 (the default, left) and 100 (the maximum, right).
  
• The Color Strength slider works with the Tint color picker to allow you to add a color overtone to your transition. In the left image below, we start the Cool preset, which uses a Color Strength of 65 and a turquoise Tint. The right image shows the same parameter values, except with Tint changed to orange.
  
• The Blend Mode drop-down menu offers the usual assortment of blending modes to composite your effect over the original image.
