  • 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 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.
