Speed & time
Time is a creative tool. Speed up a boring stretch, ramp into a hero moment, hold on a freeze frame, or automatically cut the dead air out of a talking clip. These controls live in the Inspector's Speed section when a clip is selected.
Speed, reverse and freeze frame
Inspector › Speed
Change how fast a clip plays, run it backwards, or hold a single frame.
- Select a clip and open Speed in the Inspector.
- Set the Speed value to slow down (below 100%) or speed up (above 100%).
- Toggle Reverse playback, or add a Freeze frame to hold the current image.
Smooth slow motion
Inspector › Speed › Smooth slow-mo
Instead of duplicating frames, Caliptus can generate new in-between frames for fluid slow motion.
- Slow a clip down, then enable Smooth slow-mo.
- Choose the Standard engine for a fast, optical-flow result.
- Choose the AI engine (RIFE) for superior quality on complex motion; the model downloads on first use and the render takes longer.
Smooth slow-mo is applied on export, so playback stays responsive while you edit.
Speed curves (ramps)
Inspector › Speed › Speed curve
Vary the speed within a single clip for cinematic ramps: slow, then snap to fast, then slow again.
- Open Speed curve on the selected clip.
- Pick a preset shape such as Ease in, Ease out, Hero or Flash.
- The clip is split into segments at different speeds to create the ramp.
Cut silences
Inspector › Cut silences
Automatically detect and remove the quiet gaps in a talking clip, tightening the pace in one pass.
- Select a clip that has speech.
- Open Cut silences and set the Silence threshold, minimum silence length and a little Breathing room.
- Apply: the clip is split into spoken parts with the silences removed.
