  • How to apply an ffmpeg audio effect only on a part of a video ?

    25 mars 2021, par Michael Ben Haym

    
My question is how can I apply an ffmpeg audio effect only on a certain part of a video and not on 100% of the video.
    
I have for example the following command :
    


    ffmpeg -i input.mp4 -filter_complex "afftfilt=real='hypot(re,im)*sin(0)':imag='hypot(re,im)*cos(0)':win_size=512:overlap=0.75" output.mp4


    


    this command works perfectly for me but if for example I have a video of 30 seconds and want the effect to be applied only on seconds 20-25, how do I do it ?
    
Thanks !
