[QUOTE="WayneF, post: 225181, member: 12496"] Yes, video is all the same principles, exposure is the three factors: ISO, aperture, and shutter speed. The difference is that video also has a frame rate, typically 30 frames per second. That means at 30 fps, the shutter speed cannot be longer than 1/30 second. It could be shorter though, and if you have enough light, you can use say 1/60 second shutter at a 30 frame per second frame rate. The faster shutter speed "stops motion" better, showing 30 sharper frames per second instead of 30 more fuzzy frames per second. I am hardly into video (and don't know much), but it is generally understood that too high a shutter speed makes the video look "choppy" instead of smooth. It needs a bit of blurring to run together and smooth out. A shutter speed 2x the frame rate is considered to be a good thing. Then with enough light, you don't have to use f/1.8, but could stop down for depth of field of focus. Google video shutter speed - it is a big subject. [/QUOTE]
