Don’t set your shutter speed too fast either. “The human eye likes to see a certain amount of blur. If you wave your hand in front of your face, you see some blur, but you just don’t notice it. If you set a really fast shutter speed, you’ll get super crisp movement and the eye will notice that something is wrong,” explains videographer Kenton Waltz. You want a shutter speed that’s slow enough to capture a little motion blur but a setting that’s also fast enough to minimize rolling shutter distortion.
Bring the right gear.
Minimizing camera movement, or camera shake, is another tactic for reducing rolling shutter artifacts. Invest in a good tripod or steadicam to keep your camera level while panning.
If you’re shooting with a very fast shutter speed, you may need additional lighting in the scene to keep your video from being underexposed. You’ll also need more lighting when shooting in slow motion with a rolling shutter camera. If you’re shooting with a higher frame rate, like 48 to 240 frames per second, you still need to double your shutter speed. With a shutter speed of 1/500 of a second, your sensor is not exposed for very long, so the extra lighting will keep your video from being too dark. “That’s why you see a lot of slow motion videos shot outdoors in full sunlight, because you just don’t have enough light indoors to adjust for the rolling shutter,” says Waltz. If lighting issues and the rolling shutter effect are preventing you from capturing a specific shot, you can always consider capturing that motion with a different kind of shot. But if you remember to double your frame rate with the rolling shutter, and supply your sensor with enough ambient light, capturing motion with a rolling shutter is very doable.
Stabilize your video in post-production.
Sometimes rolling shutter effects happen even though you’ve adjusted your shutter speed. Historically, image stabilization in post-production has been difficult and complex to master. But with new settings in Adobe Premiere Pro, you can use the Rolling Shutter Repair effect to mitigate wobble. Apply the effect and see how simple default settings immediately counteract the warp that occurs from the rolling shutter effect. You can also further adjust settings like Rolling Shutter Rate and Scan Direction to customize the effect for every video clip. By dragging the Rolling Shutter Rate slider left or right, you can skew the image one way or another to compensate for distortion. By setting the Scan Direction, you can adjust your video for how your individual camera scans and captures a frame, from top to bottom or left to right.
By adjusting your shutter speed, camera movement, and lighting, you can save your DSLR camera and smartphone footage from falling victim to the rolling shutter effect. And if that doesn’t work, just edit out the effect with Premiere Pro.
