[FFmpeg-user] How does one apply a filter option for a limited amount of time?

[Joseph Tyler]

I would use enable

ffmpeg -i in.mp4 -filter_complex "drawbox=w=1920:h=1080:color=black at 1:t=fill:enable='between(t,0.2,10)'"  out.mp4

Hello,

Here's my command:

ffmpeg -i in.mp4 -filter_complex
"drawbox=w=1920:h=1080:color=black at 1:t=fill" out.mp4

How do I apply it for only a few seconds to a specific time in the video?

Thanks!
