 |
Tune | Adjusts the amount of motion blur applied. Range: 0 to 4; Default: 1 |
 |
Position | Controls whether changes in position will cause motion blur. Default: on |
|
Scale | Controls whether changes in scale will cause motion blur. Default: on |
|
Angle | Controls whether changes in angle (rotation) will cause motion blur. Default: on |
Usage
Animate a layer's position, scale, or rotation using keyframes in Move & Transform, then add the Motion Blur effect.
The amount of motion blur is calculated accurately based on the amount the layer actually moved due to Move & Transform animation (including automatic animation such as from Auto Shake and Oscillate). However, sometimes for artistic reasons you may want more or less motion blur than the actual calculated amount, in which case you can override the calculated amount of motion blur by adjusting the Tune property.
Framerate and Motion Blur
Motion Blur calculates motion blur for each frame by checking how far the layer has moved since the previous frame. This means that the amount of blur can change depending on the frame rate of the project. For example, a 60fps project will have half the motion blur of a 32fps project (just like motion blur from a real camera). If you want more motion blur on a higher frame rate, you can adust Tune as desired.
Unsupported Cases
Motion blur is simulated, so there are some situations where it may not work as expected, or may not be supported at all.
- Motion blur doesn't work with faux 3D effects like Box and Cylinder.
- Motion blur doesn't recognize motion from keyframe animation in procedural effects like Checker and Stripes.
- Motion blur doesn't blur changes to other properties, such as Color & Fill or Border & Shadow.
For unsupported cases like these, consider using effects like Spin Blur or Directional Blur to approximate motion blur.
Starting and Finishing with Motion
When a Move & Transform animation starts or finishes abruptly, there is a sudden change in velocity that can cause there to be too much (or not enough) motion blur.
The easiest way to fix this is to adjust the animation Easing curves so that the motion starts and finishes gradually.
Another option is to place the Move & Transform keyframes as close to the ends of the layer as possible, or even beyond the ends of the layer (to place a keyframe beyond the ends of a layer, just trim the layer longer before placing the keyframe, then trim the layer back to original size afterwards).
⚠️ Heavy Effect
This effect requires more computational power to render than normal effects in Alight Motion. Depending on the performance of your device and the settings you use for this effect, it may result in preview lag, especially if you use effects like this with many layers simultaneously or apply multiple heavy effects to the same layer.
Use Cases
- Make motion feel smoother and more fluid, especially at lower frame rates.
- Make motion seem more dynamic by exaggerating the motion blur by increasing Tune.
