Motion blur
Blurs motion over time by drawing the drawable several times within an exposure and averaging the results. Each sample includes the drawable, its transforms, opacity, media, and the effects before this one. Effects after this one and the drawable's blend mode apply once, to the average.

Properties
Shutter angle (°) (ShutterAngle)
Exposure relative to one frame: 180 is half a frame, 360 is one frame, and 720 is two frames. 3600 is the maximum (10 frames). 0 draws only the current time.
- Type:
float - Default:
180 - Animatable: Yes
- Range:
[0, 3600]
Exposure reference (ShutterPosition)
Places the current frame at the Center, Start, or End of the exposure. End puts the trail in the past.
- Type:
ShutterPosition - Default:
ShutterPosition.Center - Animatable: No
Samples
Number of samples across the exposure. More samples reduce gaps between the images but increase render time and memory use. 1 draws only the current time.
- Type:
int - Default:
8 - Animatable: No
- Range:
[1, 64]
Source mix (%) (SourceMix)
Mixes in the current-time image: 0 is only motion blur and 100 is only the original. Static content keeps its opacity at any value.
- Type:
float - Default:
0 - Animatable: Yes
- Range:
[0, 100]
Usage
Add this effect to a drawable with animated transforms or a moving source. Place effects that should move with the drawable before it, and effects that should apply to the blurred result after it. The sample times follow the output's frame rate, so 180 is half a frame at any rate.
