If you shoot video on any of the current Nikon or Canon DSLR’s you will encounter something called “rolling shutter.”
Rolling shutter is related to CMOS sensors like those found on the Canon 5D MK II, the Nikon D3s, etc.. Since not all parts of the image are recorded at the same time, fast moving objects or a fast moving camera can cause distortion.
The two main visual symptoms of rolling shutter are skew and wobble.
How can you reduce the impact of rolling shutter?
1. Shoot at slower shutter speeds. The motion blur associated with slower shutter speeds masks rolling shutter.
2. Stabilize. Use a steady rig or a tripod.
3. Shoot with shorter lenses.
4. Use plug-ins in post such as the one sold by .
5. Don’t whip pan. Be slow and smooth when you pan.
6. De-focus the background.
Personally, once I learned the limitations of rolling shutter, I just figured out how to shoot around it, which is the best solution of all. It’s nowhere near a deal breaker for me. While it can be inconvenient, and I assume that the engineers who design these cameras are working on a solution, these simple steps can help you get great video right now.
