  • How can I cut a video to a certain length and add an intro video to it using ffmpeg-python ?

    3 septembre 2021, par kup

    How can I cut a video to a certain length and add an intro video to it using ffmpeg-python ?

    


    I am doing this :

    


    intro = ffmpeg.input(intro)
mainvid = ffmpeg.input(mainvid)

v1 = intro.video
a1 = intro.audio
v2 = mainvid.video
a2 = mainvid.audio

joined = ffmpeg.concat(v1, a1, v2, a2, v=1, a=1).node
v3 = joined[0]
a3 = joined[1]

(
    ffmpeg
    .output(
        v3,
        a3,
        'out.mkv',
        vcodec='libx265', )
    .run()
)


    


    But I don’t know how to cut *mainvid to a certain length like 10 minutes before joining. I know ss will help, but I don’t know how to use it for only mainvid.
