Hello, future Neil! You are probably trying to remember how you blurred part of a video. You blurred the bottom left portion of a circus video, using `ffmpeg`. You used: ffmpeg -i vid.mp4 -filter_complex "[0:v]crop=440:80:0:370,boxblur=2[mask];[0:v][mask]overlay=0:370[v]" -map "[v]" -map 0:a -c:a copy vid-with-blur.mp4 where: * `crop=440:80`: this is the size of the boxblur, 440px wide, 80px high * `:0:370`: this is the position of the boxblur, starting from left top. i.e. 0 pixels from the left, 370 pixels from the top * `boxblur=2`: this is how dense the blurring is. 2 is quite weak; 10 is strong * `overlay=0:370`: this needs to match the position of the boxblur

Box blur photo effect online. Apply it in your browser without changing the source file. Preview the strength and download the result.
