  • 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.

  • How to convert a CCTV footage into time lapse video by cutting parts of the video by a set interval on FFMPEG [duplicate]

    2 décembre 2020, par mark

    I have bunch of CCTV footages and I want it to look like it was recorded from a time lapse camera. One video file is around 3 hours long capturing scenes in real time (from 1pm-3pm for example). And in one day, I'll get around 8 footages (8files * 3hours = 24hours = 1 day)

    


    I want to convert those 24hours worth of footages to 1min making 1 day = 1min of video not just making it fast but actually cutting some of the scenes by a set interval. Usually, a time lapse camera has an interval of one photo per 10 min and at the end of the day, it will stitch them into one video. How can I do something like that on FFMPEG ?

    


    I'm using FFmpeg Batch converter and here's my code so far. It just makes my videos faster but not cutting it into itervals

    


    -filter:v "setpts=0.25*PTS" -an


    


    I ended up with this code :

    


    -vf framestep=25,select='not(mod(n,1000))',setpts=N/FRAME_RATE/TB -an


    


    The above code will make a 1hr long video into 4sec which is perfect for my needs.
