Old phone videos often have only 7–15 frames per second and look choppy. Smooth motion generates in-between frames from the motion and fills dropped frames.

What it does

Old phone videos (7–15 fps) become 30 fps.
24, 25 and 30 fps videos become 48, 50 or 60 fps.
Videos that are already smooth enough show "Not needed".

Turn it on

Choose a video and select Pro AI (smooth motion is available in Pro mode).
Turn on Smooth motion (30 / 60 FPS) · 2x credits in the options, or say yes when the app asks "Turn on smooth motion (2x frames)?".
Start the enhancement.

Good to know

It uses 2x credits and takes longer to process.
The phone works longer and can get warmer. If it heats up, the app slows down by itself; the quality stays the same.
The video file gets somewhat larger.
If the frame rate can’t be read, 2x credits are only charged if smooth motion can really be applied.

Don’t want the question every time? In Settings, turn off Ask about smooth motion; it then stays off unless you switch it on.
