Surprisingly, these actually do something.
Choose a size to re-encode with two-pass FFmpeg. Large videos may lose quality, and impossible targets will be rejected rather than truncated.
Choose a file to preview it, then drag the handles or enter exact timestamps.
Fast cuts are limited by video keyframes. Precise cuts can re-encode for accuracy. Processing happens on the Mochi server, not in your browser.
We aim to keep the download under your chosen size, reducing quality first, then dimensions if needed. A tiny target may be impossible. Animated GIFs use the first frame.
Compatible audio or video streams are copied without re-encoding where possible. Otherwise, FFmpeg does its thing.
