FFmpeg: Blur video

Raw

gistfile1.sh

ffmpeg -i intro.mov -vf "boxblur=5:1" intro-blur.mov

ghost commented Oct 5, 2021

default values: -vf boxblur === -vf boxblur=luma_radius=2:luma_power=2.
blur just a part of the frame: -vf boxblur=w=20:h=20:x=400:y=200.
blur just for a few seconds of the video's timeline (example: 00:00:03-00:10:00) -vf boxblur=enable='between(t,3,10*60)'.
combine those freely, order is not important (: to separate arguments, = to specify value).
f.y.i, enable is available for any filter! (when it makes sense, not much for crop, for example..).
