  • Blending Videos in FFmpeg : Excluding Transparent Areas from the Blend [closed]

    12 novembre 2024, par li lu

    I have two videos : one background video and one foreground video (with doves flying, containing an alpha channel). I want to blend these two videos so that only the dove parts participate in the blending, while the transparent parts do not. When I use the ffmpeg blend filter, the overall color of the output video changes, as if the entire video is being blended.

  • how to put a red frame before each video programmatically, when concatenating videos using ffmpeg

    7 février 2023, par Maifee Ul Asad

    To merge files with ffmpeg I'm creating a text file like this :

    


    file 'a.mkv'
file 'b.mkv'
file 'c.mkv'


    


    Then I'm running this command to concat these videos :

    


    ffmpeg -f concat -i file.txt -c copy merged.mkv


    


    But the thing is, I want to put red frame for three seconds in the middle of each video.

    


    Now I can get these videos' frame dimensions and create a video and modify the text file like this :

    


    file 'red.mkv'
file 'a.mkv'
file 'red.mkv'
file 'b.mkv'
file 'red.mkv'
file 'c.mkv'


    


    But this is not a programmatical approach, so is there any way I can concat videos and put red frames for three seconds (before every video) ?

    


    I want to generate that red frame video, on run time.
