How to Use This Calculator

Enter Desired Slow-Motion Factor — 2× plays at half speed, 4× at quarter speed, etc.
Set Playback FPS — typically 24 fps for cinematic delivery.
Capture FPS Needed is the frame rate your camera must shoot to achieve the effect.
Output Duration (sec) tells you how long the slow-motion clip will run in the edit.
Total Frames gives the exact frame count your camera must record.
Est. Storage (MB) helps you plan card capacity before going to set.

How the result changes with Playback Frame Rate

Playback Frame Rate: Frame rate of final output playback (usually 24 or 30 fps).
Slow-Motion Factor: How many times slower than real-time (e.g., 4× = quarter speed).
Real-Time Clip Duration: Actual duration of the action being filmed.
