Slow motion turns a regular-speed clip into a smooth slow-mo plate. AI interpolates intermediate frames between your originals, so you don’t see the jumps or judder you get when you just slow a clip down in an editor.

​
What it’s for

  • Turn a phone recording (that wasn’t shot in slow-mo) into a cinematic plate.
  • Highlight gestures, expressions or details that fly past at full speed (bird wings, splashes, transitions).
  • Intros and B-roll for reels where the slow pace is the “wow”.

​
How it works

1

Upload your clip

MP4, any format (horizontal or vertical).
2

Pick the factor

2x (half speed) or 4x (quarter). 4x is very cinematic but the clip lasts twice as long as 2x.
3

Generate and download

Runs in ~20-30 seconds. Download the final MP4, ready to post.

​
Cost

Source duration × factorApprox cost
4 s at 2x8 cr
8 s at 2x16 cr
4 s at 4x16 cr
8 s at 4x32 cr
Priced per second of the source (2 cr/s at 2x, 4 cr/s at 4x). Higher factor costs more because we generate more frames.

​
Best practices

  • Start with short clips (3-6 s). 4x slow-mo on 6 s is already 24 s of output, plenty for a B-roll plate.
  • Steady camera and well-lit subject pay off: interpolation needs to see well to invent well.
  • Pair with Upscale video if you start from low resolution and want slow-mo AND sharpness.

​
Limits

  • No audio: the result comes muted. Add music or foley in your editor.
  • MP4 only.
