When it comes to capturing high-speed footage, understanding the relationship between frame rate and shutter speed is crucial. With the increasing popularity of high-frame-rate cameras, many filmmakers and videographers are turning to 120 frames per second (FPS) to create smooth, realistic, and engaging visuals. However, to achieve the desired effect, it’s essential to choose the right shutter speed. In this article, we’ll delve into the world of shutter speed and explore the best practices for using 120 FPS.
Understanding Shutter Speed and Frame Rate
Shutter speed and frame rate are two fundamental components of video production. Shutter speed refers to the length of time the camera’s shutter is open, measured in seconds or fractions of a second. Frame rate, on the other hand, is the number of frames captured per second. When working with high frame rates like 120 FPS, the goal is to create a seamless and realistic representation of motion. To achieve this, the shutter speed must be carefully selected to avoid unwanted artifacts and ensure a natural look.
The Relationship Between Shutter Speed and Frame Rate
The relationship between shutter speed and frame rate is governed by the 180-degree shutter rule. This rule states that the shutter speed should be set to twice the frame rate. For example, when shooting at 24 FPS, the shutter speed should be set to 1/48th of a second. However, when working with high frame rates like 120 FPS, the shutter speed needs to be adjusted accordingly. A commonly used guideline is to set the shutter speed to 1/240th of a second or faster when shooting at 120 FPS.
Why Shutter Speed Matters at 120 FPS
When shooting at 120 FPS, the goal is to create a smooth and realistic representation of motion. If the shutter speed is too slow, it can introduce unwanted artifacts like motion blur or strobe effects.
