The higher the number, the more motion blur you’ll incur when shooting slow motion. For example, if your frame rate is 24 fps, your shutter speed should be 1/48 second or 180 degrees. The 180-Degree Shutter Rule states that your shutter speed needs to be 1/(2 x frame rate)-that is, one over two times your frame rate. Third, keep a 180-degree shutter angle in mind. If you’re shooting in artificial light, the light sources may flicker when you capture the shot. When you shoot with a fast shutter speed, you need more light to illuminate an image. Feel free to move the camera rapidly when shooting for slow motion. For instance, a regular camera pan would move at a snail’s pace in slow motion. Keep in mind how and where you’re shooting. You can’t use a fast-motion video camera and expect flawless results, though. The result is a smooth and seamless slow-motion scene. Even though the footage may play at half the original speed, it doesn’t appear choppy or stilted because the original clip had twice as much footage as the clip with 30 fps. A video editor can slow down a video shot from 60 fps to 30 fps.
