FPS Calculator

Enter the frame rate a clip was made at, the frame rate of your timeline and its length. The calculator shows playback speed, frame duration and the new clip length.

How to use it

  1. Enter the clip fps and the timeline fps.
  2. Add the clip length.
  3. Use the slow-motion percentage when you retime the clip in your editor.

Frequently asked questions

How do I get slow motion?

Play a high frame rate clip on a lower frame rate timeline, for example 60 fps on 24 fps plays at 40% speed.

Do AI clips have real extra frames?

Only if the model rendered them. Frame interpolation can create in-between frames, with mixed results.
