Minimizing camera movement, or camera shake, is another tactic for reducing rolling shutter artifacts. 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. 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. If you wave your hand in front of your face, you see some blur, but you just don’t notice it. “The human eye likes to see a certain amount of blur. These rolling shutter artifacts can also occur if your camera is in motion while filming, which can alter your perspective and create distracting distortions.ĭon’t set your shutter speed too fast either. If you’re shooting video of fast-moving subjects, like airplane propellers spinning or guitar strings vibrating, the rolling shutter can result in wobble, or the “Jello effect.” Part of the frame may blur, or straight lines may appear curved and bent. Rolling shutter becomes an issue for videographers when movement comes into play. When rolling shutter effects are noticeable. They’re an effective tool for beginners, but they do have their drawbacks. “Rolling shutter cameras are efficient at capturing fast frame rates, without creating excess physical heat in the camera and drawing massive amounts of battery power,” explains filmmaker and videographer Taylor Kavanaugh. Cameras with a CCD sensor, or global shutter, will record an entire image all at once, but these cameras are significantly more expensive and difficult to manufacture. DSLR cameras with a standard CMOS sensor or smartphones, like iPhones, are all rolling shutter cameras. There are two types of modern image sensors: CMOS and CCD. ![]() ![]() This slight lag can create some unintended distortions if you’re filming fast-moving subjects or panning your video camera across a scene. ![]() The rolling shutter sensor scans from the top of the image to the bottom, so the top of the frame is recorded slightly earlier than the bottom. A rolling shutter is a type of image capture in cameras that records the frame line by line on an image sensor instead of capturing the entire frame all at once.
