How to Shoot Slow Motion – Video Tips | B&H

Shooting a good slow motion video requires three key steps: frame rate, shutter speed, and lighting. Step 1: Frame Rate A good slow motion shot begins with shooting at a higher number of frames per second (FPS). Cinema is generally shot at 24 fps, so if you shoot at 120 frames per second, and then play that back at 24 fps, the video will appear five times slower. To determine the best frame rate for your scene, think about the necessary speed to capture the action properly. You don’t want the slow motion to be too slow or too fast, so finding a sweet middle ground is important. You should also consider how long you want the playback to be. So if you want the slow-mo scene to last 10 seconds, you might want to consider a frame rate that isn’t too slow so the scene doesn’t drag on. Step 2: Shutter Speed Shutter speed dictates the amount of motion blur the subject is going to have. The longer your shutter stays open, the blurrier any action of the frame is going to appear. The rule of thumb for a natural-looking amount of motion blur is to set your shutter speed at double your frame rate. If your camera supports shutter angle, 180 degrees will always be double your frame rate. A shutter speed that’s too fast may make the shot look a little too choppy but too slow and you run the risk of having too much motion blur. When shooting slow motion, it’s best to consider your subject and how much movement there’s going to be. For action scenes where there’s a lot of quick movement, some people prefer to shoot a faster shutter, ensuring that each individual frame is sharp; although you may want more motion blue as part of your aesthetics. It’s up to you. Step 3: Lighting The faster frame rates and shutter speeds necessary for slow-motion shooting means that your camera sensor is going to have less time to capture light for each frame. This means you’re going to need a lot more light than usual to properly expose a shot. Here are some lighting tips when filming in slow motion: • When using tungsten lights, use tungsten lights 2k or higher to avoid light flickering (further explanation at 3:04). Alternatively, you can eliminate flicker from any tungsten light entirely by running it from a direct current source like a generator • HMI fluorescent lights are typically fine if they use electronic, flicker-free ballasts • LED is becoming increasingly accepted for high-speed performance. Most units made for professional use will not have flickering issues. • The Sun will always be the best source for flicker-free lighting!
