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. β 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. β 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. β Cut only what you need Keep a section or cut it out. (Pro) β 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 β for practice and analysis, too. β Privacy Crank never sends your video to an external server. All video processing happens only on your device.
