Simulate the motion blur created by zooming a camera lens during a long exposure. The tool samples the image along radial lines projecting from a center point, creating streaks that convey explosive speed and outward motion.
Burst intensity and smoothness
Burst Intensity determines the length of the radial streaks. Low values leave the image mostly intact with a slight radial haze. High values pull pixels far away from their original positions, obscuring background details and creating a severe motion effect.
Smoothness controls how many individual samples are averaged to draw each streak. A higher sample count produces a perfectly smooth gradient trail, while a lower sample count may show discrete steps or bands along the blur path.
Burst origin positioning
Center X and Center Y shift the origin point of the zoom burst. By default, the burst originates from the exact center of the image. Moving the origin allows you to anchor the sharpest part of the burst over a specific subject, ensuring they remain recognizable while the rest of the frame streaks away from them. Placing the origin near a corner creates a dramatic diagonal motion effect.
