Give a clip the explosive radial streaks of a zoom pulled during a long exposure. Detail near the center stays readable while the edges of the frame blur outward.

Intensity and smoothness

Burst Intensity sets how far the streaks reach. Low values add a faint radial haze; high values pull the edges into long rays. Smoothness sets how many samples make up each streak: more samples give a clean gradient at a higher cost per frame.

Center point

Center X and Center Y position the origin of the burst. Put it on the subject so the subject stays sharpest. For footage moving toward the camera, such as a road from a moving car, the burst adds a strong sense of speed.

Frequently Asked Questions

How is the zoom burst drawn?

Each pixel is averaged with samples along a line running outward from the center. Burst Intensity sets the length of that line and Smoothness the number of samples.

Why are there visible steps in the streaks?

Too few samples for the streak length. Raise Smoothness; each extra sample adds work per frame, so long clips export more slowly.

Can I keep a subject sharp?

Yes, near the burst center, where the streaks are shortest. Move Center X and Center Y onto the subject.

What happens to the audio?

It is copied into the export unchanged when the container can hold its codec, and re-encoded when it cannot. A note under the export button says which happened.

Zoom Burst Effect

Simulate a long-exposure zoom burst by averaging radial samples from a center point. Adjust burst intensity, smoothness, and the origin point to create motion trails.

Blur Video

Blur every frame of a video with a Gaussian blur, and mix the blurred frame back over the sharp one to soften rather than erase detail. The blur scales with the output size, so the preview matches the export. Exports MP4 or WebM with the original soundtrack.

Chromatic Aberration Video Effect

Split the red and blue channels of every video frame outward from the center or along one axis for lens color fringing. Set strength, fringe colors, and a protected center. Exports MP4 or WebM with the original soundtrack.

Kaleidoscope Video Effect

Mirror every frame of a video into 2 to 24 symmetric segments around the center for a moving kaleidoscope. Set segment count, rotation, and zoom. Exports MP4 or WebM with the original soundtrack.

Lens Distortion Video Effect

Bend every frame of a video with barrel or pincushion lens distortion. Set curvature from -100% to 100%, zoom, and whether the uncovered edges are black or stretched. Exports MP4 or WebM with the original soundtrack.

Aerochrome Video Effect

Give a video the false-color infrared look of Kodak Aerochrome: green foliage turns red or magenta while skies stay blue, with film grain that moves on every frame. Set profile, intensity, foliage, and red bloom. Exports MP4 or WebM with the original soundtrack.

Blueprint Video Effect

Turn every frame of a video into a blueprint drawing: white edge lines on drafting blue with a measured grid. Set edge intensity, blue hue, and grid opacity. Exports MP4 or WebM with the original soundtrack.

Cyanotype Video Effect

Print every frame of a video as a cyanotype: Prussian blue shadows, pale paper highlights, and a fixed paper texture of stains and fibre. Set pigment color, exposure, contrast, and depth. Exports MP4 or WebM with the original soundtrack.

Engraving Video Effect

Turn every frame of a video into an antique engraving: hatch lines that follow the form, crosshatching in the shadows, and etched edges that move slightly on every frame. Set ink and paper colors, exposure, and line density. Exports MP4 or WebM with the original soundtrack.
