Make the highlights in a clip sparkle. Bright points such as jewellery, water, eyes, and lamps pick up star-shaped rays, and the stars change position on every frame so the clip twinkles.

Threshold and density

Highlight Threshold decides which points qualify; raise it toward 240 so only the brightest glints sparkle. Density sets how many qualifying points actually get a star.

Ray size and count

Ray Size is relative to the frame, so the stars keep their size at every export resolution. Ray Count sets how many rays each star has, from 4 to 12.

Footage that works

Glitter, sequins, sunlit water, snow, and night lights give the most points to sparkle. Flat, evenly lit footage has few highlights above the threshold and gets few stars.

Frequently Asked Questions

Where do the sparkles appear?

On points brighter than Highlight Threshold. Sparkle Density and a seed decide which of those points get rays, so not every bright pixel turns into a star.

Do the sparkles twinkle?

Yes. The seed advances 30 times per second of source time, so the selection of lit points changes on every frame and the stars flicker like glitter catching light.

What ray count looks most like a real lens?

6 or 8 with a small ray size. Real starbursts come from light diffracting around aperture blades, which produces even ray counts. 12 large rays read as decoration.

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.

Sparkle Photo Effect

Detect bright pixels and add seeded starbursts with adjustable threshold, density, relative ray size, ray count, and tint.

Break the edges in every frame of a video into particles that drift left, right, up, or down, with a new particle layout on every frame. Set particle amount, travel distance, edge threshold, and direction. Exports MP4 or WebM with the original soundtrack.

Drip Video Effect

Pull the strong edges in every frame of a video into downward paint trails, with new trails drawn on every frame. Set drip length, trail spread, edge threshold, and drip amount. Exports MP4 or WebM with the original soundtrack.
