Slow Motion Calculator
Find the perfect speed percentage to get smooth slow motion without dropping or duplicating frames.
Set Clip Speed To
40.00%
To get perfectly smooth slow motion (where every frame of your source file is played back 1-to-1 on your timeline), set your clip speed to 40.00%.
In Premiere Pro:
- Right-click your clip on the timeline
- Select Speed/Duration...
- Enter 40.00% in the Speed box
How does slow motion work?
Smooth slow motion happens when you play high frame rate footage (like 60fps) on a lower frame rate timeline (like 24fps).
To get 1-to-1 frame playback, you must reduce the clip speed to the exact ratio of the two frame rates.
Use this calculator to find that exact percentage for Premiere Pro's Speed/Duration tool.
