  • How to create a video of a precise duration from a single image or by trimming a video using FFmpeg ? [closed]

    29 mai 2024, par aas

    I'm trying to create a video from a single image with a very specific duration of 0.09375 seconds using FFmpeg. I've tried various commands, but I can't seem to get the exact duration I need. The closest I've gotten is 0.080000 seconds. It doesn't always have to be something like 0.09375, but I wanted to have an example for it.

    


    I've also tried trimming a video, but from what I've read so far, the encoding of the video can be a problem. Even after trying different FFmpeg commands or using MoviePy directly, I've never arrived at the desired result.

    


    Here are the steps I've taken so far :

    


    Initial Attempt :

    


    ffmpeg -loop 1 -i frame_00001.png -c:v libx264 -t 0.09375 -r 240 -pix_fmt yuv420p -vf scale=1920:1080 output.mp4


    


    Resulting duration : 0.080000 seconds

    


    Adjusted Frame Rate :

    


    ffmpeg -y -loop 1 -i frame_00001.png -c:v libx264 -t 0.09375 -r 160 -pix_fmt yuv420p -vf scale=1920:1080 output.mp4


    


    Resulting duration : 0.081250 seconds

    


    I've also tried using the setpts filter, but I didn't get anything satisfying.

    


    Creating a video from a single image or trimming an existing video were my two ideas, but if anyone has another method to create a video with such a precise duration, I'm all ears !

    


    Any guidance or suggestions would be greatly appreciated.

  • 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.
