Crop a video precisely
Set the crop box yourself: exact width, height and X/Y offset, with a live preview and the amount removed from each side. Runs in your browser.
Choose a video to begin.
The preview and processor use the same selected file. Invalid boxes are rejected. Odd dimensions and offsets round down to the even 4:2:0 grid shown above; there is no subject detection.
How this differs from the platform crop tools
- You choose the box
The per-platform crop tools centre the frame automatically. Here you set the crop box, with any even-pixel adjustment shown, which is what an off-centre subject needs.
- No subject detection
Nothing here finds the face or the action. If you want the box somewhere specific, put it there.
- Even dimensions enforced
This H.264 / 4:2:0 export uses even width, height and X/Y offsets, so odd values are rounded down and the adjustment is shown rather than applied silently.
Koldflux reframes automatically, tracking the subject across the cut.
