You might ask your self, what’s the Best shutter speed for my video? Let’s take a look into answering that now!
When filming videos there are typically three settings you need to concern yourself with, Aperture, ISO, and shutter speed. In my previous video I covered ISO settings, and now I wanted to talk about shutter speed. On a digital camera, shutter speed is a way to describe the length of time the shutter stays open when you press the button to take a picture. For this scene I have my shutter speed set to 1/60. So that means the shutter is open for 1/60th of a second. A shutter speed of 1/30 would be 1/30th of a second. Because the shutter is closing so quickly, it’s only able to let in a certain amount of light. The faster you have the shutter speed, the less light the camera will be able to take in. So if I’m filming, and it’s a dark scene, can I just lower the shutter speed to let in more light? Well… not quite. Let me show you what happens at lower shutter speeds.
You notice when filming the lower shutter speeds had really stop motion footage. It wasn’t smooth. Then as the shutter speed increased, the footage quality was smoother, but there was less light on the scene. From this testing the minimum that looked smooth was at 1/60 shutter speed. And this is related to the frame rate I’m filming at. Right now I’m filming at 1080p/60. So the original footage was shot at 60 frames. Therefore the minimum you ever want to set your shutter speed is equivalent to the frame rate you are filming at. My Canon m50 can shoot at these settings, so I would match up the frames per second and shutter speed the same.
When looking at the footage though, the 1/120 looked better than the 1/60. Let’s try to figure out why.
The original cameras used a rotary shutter, that spun in a circle, and it would be 180 degrees or 1/48th shutter speed for shooting 24p video. When looking at film this is what we are most accustom to seeing, that is why the general recommendation are these settings. That’s also why the recommendations carried over to doubling up your shutter speed according to your frame rate
|Frames Per Second ||Recommended Shutter Speed|
|24 (american film)||1/48 or 1/50|
|25 (european film)||1/50|
|30 (american tv)||1/60|
|60 (american monitors)||1/120 or 1/125|
