How slow will my footage actually play, and what shutter follows?
Enter your capture and delivery frame rates to see the slow-motion factor, delivered duration, and the shutter time that follows.

Slow motion is a time trade with linked consequences
Slow motion is a time trade: capture more frames each second than you play back, and the action stretches at delivery. The same choice also changes the shutter time available per frame, often increasing the light requirement and the data burden. This planner keeps those linked consequences in one decision rather than treating high frame rate as a button.
Capture at 120 frames per second and deliver at 24fps for five-times slow motion. Five seconds of action becomes 25 seconds at playback. A 180-degree starting shutter at 120fps is 1/240 second; at 240fps it becomes 1/480 second. The shorter exposure can reduce motion blur but needs more light. Confirm the actual camera mode and test the real light for flicker before relying on the plan.
This is a planning calculation, not a certification. Confirm the relevant camera, lens, card, printer, contract, location, or workflow constraint in the real setup before relying on the result.
Make one controlled test with the important variable held constant. Inspect the subject detail, motion, highlights, and intended output, then adjust the setting that protects the priority you named.
FAQ
- Does 120fps always mean five-times slow motion?
- Only when delivery is 24fps. The slow factor is capture frame rate divided by delivery frame rate.
- Is this a guarantee?
- No. The result is bounded by the inputs and assumptions shown on the page. It is designed to support a better next decision, not replace a test, measurement, proof, or professional judgement where one is needed.
