The rolling shutter effect is an often-overlooked problem in recording video with digital cameras and devices. When using mechanical shutters, this issue can have a big impact on the final product—and it’s important to understand how it works and how it impacts video quality. With the recent shift toward electronic shutters, many filmmakers and video producers are now considering whether electronic or mechanical shutters are the best choice for their projects.
What is the Rolling Shutter Effect?
The rolling shutter effect is a side effect of video recording with digital cameras that use a mechanical shutter. When a camera records video, the shutter temporarily opens and closes to capture each frame. The rolling shutter effect occurs when there are moving objects in the frame, and the capture of each scanline is separated in time. This can create a “jello” effect, where fast-moving objects appear distorted or tilted as the frame is being recorded.
Mechanical Shutter vs. Electronic Shutter
Mechanical shutters are the traditional method of capturing images, and they are still commonly used in many digital cameras. When the rolling shutter effect is a concern, it can be a good idea to use an electronic shutter instead. Electronic shutters work by turning pixels on and off, and this can significantly reduce the rolling shutter effect. Modern digital cameras are also capable of capturing images with an electronic global shutter, which captures all the scanlines at the same time and therefore doesn’t exhibit any rolling shutter effect at all.
Video Quality Considerations
When it comes to video quality, both mechanical and electronic shutters have their pros and cons. Mechanical shutters can produce the classic film-like look that many cinematographers seek, but they can also be prone to the rolling shutter effect. Electronic shutters, on the other hand, can produce a smoother look, reducing the rolling shutter effect, but can also produce an artificial look in the final product.
When it comes to choosing the best shutter for your project, it’s important to consider what type of look and feel you are aiming for and how the rolling shutter effect may impact your video quality. If you are looking for a classic film look, then mechanical shutters may be the best option. If, however, you are concerned about the rolling shutter effect, then electronic shutters may be the better choice.
Conclusion
As the type of camera and electronic shutter technology improves, more and more filmmakers will have to consider the rolling shutter effect when recording video. The rolling shutter effect can have a big impact on video quality, so it’s important to understand how it works, what type of shutter is used, and how it’ll impact the final product.
