Why do cameras use rolling shutter?
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.This slight lag can create some unintended distortions if you’re filming fast-moving subjects or panning your video camera across a scene.

Rolling shutter is the answer to why concrete bends, propellors break up, and trees turn to jelly when you’re filming them while either you, or the object, is moving quickly in front of certain cameras.This is an electronic shutter, but film cameras would suffer the same with their spinning semi-circle shutter shapes.
What is bad rolling shutter?
The problem with rolling shutter for digital filmmaking or videomaking is that it doesn’t scan the image fast enough to accurately capture fast-moving images in front of the lens. This results in focal plane distortion.
Why does stabilization take so long on iMovie?
