Ken Burns effect
Also called pan and zoom, pan and scan effect
What is the Ken Burns effect?
The Ken Burns effect is a video technique that adds slow panning and zooming to a still photograph. The camera seems to drift across the image or push in on a detail, which gives movement to a picture that would otherwise sit static on screen. It is widely used in documentaries, slideshows and social videos built from photos.
The effect is named after the American documentary filmmaker Ken Burns, who used it heavily with archive photographs in his historical films. The technique itself is older: filmmakers had filmed still images with moving rostrum cameras for decades. Apple later put the name on the feature in its photo and video software, which made the term common.
In editing software it is often called pan and zoom. You set a start frame and an end frame on the photo, and the software animates between them. Small, slow moves look best; fast zooms on low-resolution images look cheap and blurry.
Why the Ken Burns effect matters
Many businesses have far more photos than video footage. The Ken Burns effect turns product shots, event photos and screenshots into usable video, which matters on platforms that favor motion over still images.
Movement holds attention. A slow push in on a detail directs the eye and keeps a promo video from feeling like a static slideshow.
How to create a Ken Burns effect
- Choose high-resolution photos, ideally larger than your video frame, so zooming stays sharp.
- Decide what each move should reveal: a face, a product detail or a sign.
- Set a start and end framing; keep the zoom modest, around 5 to 20 percent over the clip.
- Use slow, steady moves of 3 to 6 seconds, and ease in and out.
- Vary direction between photos (in, out, left, right) so the sequence does not feel repetitive.
Ken Burns effect example
A bike shop has photos but no footage of last year's group ride. The editor starts wide on a photo of thirty riders at the start line and slowly zooms toward the shop banner over four seconds, then pans across a close-up of muddy tires on the next photo while the voiceover says "Join us for this year's ride."

Why is it called the Ken Burns effect?
It is named after documentary filmmaker Ken Burns, who used slow pans and zooms over archive photos throughout his historical documentaries.
Is image to video the same as the Ken Burns effect?
No. The Ken Burns effect moves a virtual camera over a flat still. AI image to video models generate new frames, so things inside the picture can move, such as people walking or water flowing.
