· slow shutter effect

The slow shutter look, on footage you already shot.

Moving things leave soft streaks of light at a low, choppy frame rate, like a dragged shutter. Drag it onto a clip and press play. DaVinci Resolve only, free or Studio.

The same clip with the effect off and on. Streaks follow whatever moves, bright things streak the most, and Frame Hold gives it the stutter of a real slow shutter.

· seven sliders

What you can change.

Everything is in the Inspector, on the clip. This is the whole panel.

The Shutterdrag controls in the DaVinci Resolve Inspector: Trail Length, Intensity, Highlights, Softness, Frame Hold, Pre-Blur X and Pre-Blur Y, each a slider with a number beside it.

Trail Length: How many frames a streak lasts.
Frame Hold: The picture changes every few frames while the streaks stay smooth: the low frame rate of a real slow shutter.
Highlights: Turn it up and lights, reflections and anything bright leave the longest trails, like a real long exposure.
Softness: A streak blurs more the older it gets. The current frame stays sharp.
Pre-Blur X / Y: Blur along the direction of travel to melt separate ghost images into one streak.
Intensity: Mix the effect with the untouched picture.
