How to blur part of a video
Pause where the thing shows and drag a box over it. It blurs from that frame to the end of the video. Play to where it should stop and press Stop here, or Start here to begin it earlier. If the thing moves, pause there and drag the box onto it: it moves from that frame on.

What to expect
- Supported inputs
- Any video this browser can play.
- What happens
- Nothing is guessed: every box blurs exactly where and when you put it. Beside each box you can see the frames either side of where it starts and stops, without the blur, and move either end a frame at a time. The picture is re-encoded; audio is unchanged.
- Limits
- There's no length limit, but a long video takes longer to blur. Something that moves needs the box put on it each time it moves.
