About
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.
