## What is Crank?

Like a DJ scratching a turntable,
turn the dial to move the video back and forth.

Turn slow and the video and sound stretch out long;
turn fast and the speed and pitch rise together.

The speed and direction of your fingertip become the video and the sound.
And you can save that motion as a brand-new video.

The feel of winding film by hand
is captured in carefully tuned haptics.

■  Scratch with the dial
Turn the dial to move the video freely, back and forth.
The video and audio speed change naturally with how fast you turn.

■  Keep the performance
Save the motion you made on the dial as a single video.
Ready to use for Reels, Stories, and short-form content.

■  Cut only what you need
Keep a section or cut it out. (Pro)

■  Export in the ratio you want
Export your video in square, vertical, or landscape.

Crank isn't only for video scratching.

Check a tennis swing one frame at a time,
watch your hands again in a piano performance,
or wind dance and workout clips to the exact moment you want.

Skip forward fast, rewind slowly,
and move frame by frame — for practice and analysis, too.

■ Privacy
Crank never sends your video to an external server.
All video processing happens only on your device.
