Before you begin
Set an overall pace
Speed up a routine movement or slow down a brief action. Changing playback speed changes the clip duration, so review how it meets the neighbouring scenes and the soundtrack.
Shape tempo within a clip
A speed curve lets the tempo change inside a shot. Try a quick opening, a slower key movement and a brisk finish. Give the most readable part of the action enough time instead of applying the same speed throughout.
Separate rhythm from smoothness
Reverse playback changes the direction of an action. If slow motion looks uneven because the source has too few frames, consider interpolation separately. Changing speed alone does not recover missing detail.
02 / Follow these steps
Follow these steps
Choose a clip with a clear movement or reveal.
Use Speed to set a constant rate or a speed curve, and reverse the clip if it suits the idea.
Check the movement, resulting duration and music timing together.
03 / Try this sequence
Try this sequence
For a jump, shorten the preparation, slow the peak of the movement and bring the pace back up after landing. Choose one main emphasis point. A restrained curve can guide attention more clearly than repeated dramatic changes.
Before you export
- Does the slow section align with the key action?
- Are speed changes smooth at the boundaries?
- Have you checked sound and duration after changing speed?
Frequently asked questions
Are speed curves the same as interpolation?
No. A speed curve changes the timing of a clip. Interpolation creates intermediate frames to improve the continuity of movement.
What footage is useful for slow motion?
Clear footage recorded at a higher frame rate generally offers more temporal detail. Review fast or blurred movements carefully before choosing how far to slow them down.
