Now, this may be obvious to many seasoned videographers, but for a lot of photographers new to the DSLR video and film world, shutter speed and video is a topic that gets very little attention. I knew that I had to set the shutter speed of my 7D to a certain value and then lock it. But I wanted more info around this topic and found

this great blog entry.

It explains how shutter speed and frame rate work together and why you always want to set up your camera this way:


24p=1/48 (or as close to that as possible)

30p=1/60

60p=1/120
(or as close to that as possible)


Following this rule will give you a very film-like look. Ignoring it will either lead to smeary video (slower shutter) or staccato motion (fast shutter speed). Both will make your video look like it came from an automatic camcorder. I'd never change the shutter speed for video unless I was going for a very specific effect.

It's all based on how the 180 degree shutter in motion picture film cameras works

Anyway, I thought the article linked above might be helpful and/or interesting for some.

    I always wondered how motion picture shutters worked!
