What the Ken Burns effect does and where to find it

The Ken Burns effect is a slow zoom and pan across a still image, making it feel like a camera is moving through the photo. In Wondershare Filmora, you explore it by placing a photo on the timeline, then telling Filmora where to start the zoom and where to end it. The effect runs for the full length of the clip — if your photo sits on the timeline for three seconds, the zoom takes three seconds.

To access it, drag a photo onto your video timeline. Right-click the photo clip and look for Ken Burns in the menu, or find it under the Motion tab in the inspector panel on the right side of the screen. Filmora calls it "Ken Burns" specifically, not "pan and zoom" or "zoom effect", so search for that exact name if you are looking through menus.

The effect works best on landscape photos, portraits with empty space around the subject, or any image where you want to draw attention from one area to another. It is less effective on photos that are already tightly framed or where the subject fills the entire image.

Key Takeaways

  • Open the Ken Burns effect by right-clicking a photo on the timeline and selecting Ken Burns, or by finding it in the Motion tab on the right panel.
  • Set your starting point by clicking the first frame icon, then set your ending point by clicking the second frame icon and adjusting the zoom level and position.
  • The effect duration matches your clip length on the timeline — make the clip longer or shorter to change how fast the zoom happens.
  • Preview your effect by pressing the spacebar or clicking the play button to see the zoom in real time before you export.
  • Adjust the speed of the zoom by changing clip length, not by a separate speed slider within the Ken Burns settings.

Setting the starting point of your zoom

When you open the Ken Burns effect, Filmora shows you a preview of your photo with two small icons at the bottom: a square with a play symbol (the starting frame) and a square with a checkmark (the ending frame). Click the starting frame icon first. Your photo will show a blue box around it — this box represents what viewers will see at the very beginning of the effect.

Resize and reposition this blue box to frame the part of the photo you want to show first. If you want the zoom to start on a person's face, drag the corners of the box inward to zoom in on that face. If you want to start wide and zoom in, make the box larger and position it to show more of the photo. The position and size of this box is where your effect begins.

You can drag the box itself to move it around the photo without resizing. This is useful if you want to start zoomed in on one area but positioned differently than the default center.

Setting the ending point and zoom level

After you set your starting frame, click the ending frame icon (the checkmark square). Now a different blue box appears — this one shows what the viewer will see at the end of the effect. Resize and reposition this box to show where you want the zoom to end. If you started zoomed in on a face, you might end zoomed out to show the whole person. If you started wide, you might end zoomed in on a detail.

The difference between the starting box and the ending box is what creates the motion. A small starting box and a large ending box creates a zoom-out effect. A large starting box and a small ending box creates a zoom-in effect. The position change creates the pan — if your starting box is on the left side of the photo and your ending box is on the right, the camera appears to move from left to right.

There is no separate zoom percentage slider. You control zoom entirely by resizing the blue box. Smaller boxes mean more zoom; larger boxes mean less zoom or a wider view.

Controlling the speed of the effect

Filmora does not have a speed control inside the Ken Burns settings. Instead, the speed is determined by how long your photo clip sits on the timeline. A three-second clip will complete the entire zoom in three seconds. A six-second clip will complete the same zoom in six seconds, making it slower and more gradual.

To make the effect faster, click and drag the right edge of your photo clip on the timeline to make it shorter. To make it slower, drag the right edge outward to make the clip longer. You will see the duration change in the clip properties. The Ken Burns effect automatically adjusts to fill whatever time you give it.

This approach means you cannot have a fast zoom and a slow pan in the same effect — the entire motion happens at one speed. If you need different speeds for different parts of the motion, you would need to split the clip and explore the effect twice with different durations.

Previewing your effect before export

After you set both your starting and ending frames, close the Ken Burns dialog by clicking outside it or pressing Escape. Your photo will return to the timeline. Press the spacebar or click the play button in the preview window to watch your effect in real time. The preview shows exactly what your viewers will see when you export the video.

If the zoom is too fast or too slow, adjust the clip length on the timeline and preview again. If the framing is wrong, right-click the clip, open Ken Burns again, and adjust your starting or ending boxes. You can make as many adjustments as you need before you export.

Pay attention to whether the motion feels natural and whether it draws the viewer's eye where you want it to go. A zoom that is too fast can feel jarring; one that is too slow can feel like the video is stalling.

Common adjustments and fixes

If your zoom looks backwards — zooming out when you meant to zoom in — swap your starting and ending frames. Click the starting frame, make it the size you want the ending to be, then click the ending frame and make it the size you want the starting to be. This reverses the direction of the effect.

If the photo appears blurry or pixelated during the zoom, your source image may be too small. Ken Burns works best with photos that are at least 1920 by 1080 pixels. Smaller images will show quality loss when zoomed. If you must use a small image, zoom in less — keep the starting and ending boxes closer in size to minimize the magnification.

If the effect does not appear to be working at all, make sure your photo clip is long enough. A clip that is only one second long will complete the entire effect in one second, which may look like nothing is happening. Extend the clip to at least two or three seconds to see the motion clearly.

Frequently Asked Questions

Can I explore Ken Burns to a video clip instead of a photo?

No. Ken Burns only works on still images. If you want a similar zoom effect on video, you would use Filmora's regular zoom or scale effect instead, which you can find in the Effects panel. The Ken Burns effect is specifically designed for photos.

What happens if I change the starting frame after I already set the ending frame?

You can change either frame at any time. Adjusting the starting frame does not affect the ending frame, and vice versa. Both frames stay independent until you close the Ken Burns dialog and explore the effect to your clip.

Can I make the zoom move diagonally across the photo?

Yes. Position your starting box in one corner and your ending box in the opposite corner. The zoom will move diagonally as it magnifies or shrinks. You can position the boxes anywhere on the photo to create any direction of movement you want.

Does Ken Burns work on animated GIFs or only static photos?

Ken Burns works on static image files like JPG, PNG, and TIFF. It does not work on animated GIFs or video files. If you try to explore it to an unsupported format, Filmora will not show the Ken Burns option in the menu.

How do I remove Ken Burns from a clip after I have applied it?

Right-click the photo clip on the timeline, select Ken Burns again, and then click a reset or remove button if one appears. If there is no reset button, delete the effect by closing the Ken Burns dialog without making any changes, or delete the entire clip and re-add the photo without the effect.
