Frame interpolation

AI slow motion without the stutter

Turn a normal-speed clip into smooth 2× or 4× slow motion. AI creates the missing frames between recorded moments, then exports a new MP4 for your edit.

Every splash becomes visible

Three AI frames between each original

4 sec source 16 sec output

One generated shot at three speeds. Melies creates the missing frames between the originals.

Control the retime

Choose how long the moment should last

Upload a short source clip, choose a speed, then generate. Slower settings create more in-between frames and a longer output.

What interpolation does

New frames fill the gap between captured frames

Simply stretching playback repeats frames and looks choppy. Frame interpolation estimates motion between them so the retimed clip keeps visual continuity.

Choose the factor

From subtle emphasis to extreme detail

01

2x

A subtle slowdown for emotional beats, product moments, and everyday motion.

02

4x

Where it works best

Motion worth studying frame by frame

Fast action, particles, fabric, water, and camera movement benefit most when the source is sharp and free of hard cuts.
