Shutter Speed Calculator – 180 Degree Rule for Video Recording
Calculate the ideal shutter speed for video recording using the 180-degree rule with our free shutter speed calculator. Enter your video frame rate to instantly get the recommended shutter speed that produces natural motion blur. This video shutter speed tool is essential for filmmakers, smartphone videographers, and content creators who want cinematic-looking footage with correct motion characteristics at any frame rate.
Shutter Speed Calculator
Calculate ideal shutter speed using the 180° rule
Shutter Speed Calculator Features
- Calculates the ideal shutter speed for video recording using the 180-degree shutter rule
- Supports three shutter angle presets: 180° (×2), 270° (×1.5), and 90° (×4)
- Accepts any frame rate as input for flexible cinematography planning
- Displays shutter speed as a fraction (e.g., 1/60) and in milliseconds
- Useful for videographers shooting cinematic footage on smartphones
- Helps avoid motion blur or overly sharp unnatural motion in video recordings
How to Use Shutter Speed Calculator
- Enter the video frame rate in fps (e.g., 30) in the “Frame Rate” field
- Select the shutter angle rule from the dropdown (e.g., 180° Rule ×2 for cinematic look)
- Click the Calculate button
- View the recommended shutter speed as a fraction and its duration in milliseconds
- Apply the result as your manual shutter speed setting in your camera app
- Click Reset to calculate for a different frame rate or shutter angle
Frequently Asked Questions
The 180-degree rule states that shutter speed should be approximately double the frame rate for natural motion blur in video. At 24fps, use 1/48s (or 1/50s). At 30fps, use 1/60s. At 60fps, use 1/120s.
Recommended Shutter Speed = 1 ÷ (Frame Rate × 2). For 24fps: 1/48s. For 60fps: 1/120s. Our shutter speed calculator applies the 180-degree rule formula automatically for any frame rate.
Using the correct shutter speed produces natural-looking motion blur that matches how the human eye perceives movement. Too fast creates “jello effect” or strobe-like motion; too slow creates excessive blur and smearing.
Yes, deliberately. Fast shutter speeds (higher than 180°) create a sharp, staccato “Saving Private Ryan” look popular in action sequences. Slow shutter speeds create dreamlike, blurry motion — both are creative choices.
Most flagship Android phones allow manual shutter speed control in Pro/Manual mode. iPhones allow this through apps like Halide or ProCamera. Some phones also have dedicated cinematic modes with shutter guidance.
Yes. Faster shutter speeds reduce light reaching the sensor, potentially requiring higher ISO or wider aperture. ND (Neutral Density) filters are commonly used to maintain the 180-degree rule in bright conditions without overexposing.
