I want to blur some scenes with avconv
The ffmpeg command -find it here- is:

ffmpeg -i input.avi -vf "boxblur=enable='between(t,22,113)'" -codec:a copy output.avi

doesn't work with avconv

avconv -i "video_in" -vf "boxblur=10:1" "video_out"

blur the whole video, what can I add to it to blur selected scenes.

  • last progress: avconv -i "video_in" -vf "select='gte(t,10)*lte(t,20)', boxblur=10:1" "video_out" but I lose lte 10 and gte 20 black screen avconv -i "video_in" -vf "select='lte(t,10)'" "select='gte(t,10)*lte(t,20)', boxblur=10:1" "select='gte(t,20)'" "video_out" doesn't work... – Learner Nov 5 '14 at 3:56
