  • Creating time lapse video from ffmpeg with jpg images

    16 mai 2021, par Rikard Svenningsen

    I am trying to creating time lapse video.
I have images file named IM_date_time.jpg as in IMG_20210516_235523.jpg (2048 × 1536)
I have around 3700 files.
I have used this command :

    


    ffmpeg -y -i IMG*.jpg -r 5 -s hd1080 output.mp4


    


    This is not working, and I don't understand why it want to write to my images. The -y should not be needed.

    


    I what to get a video in hd (full hd or just hd) and one images to represent 1 or 2 frames per sec.

    


    I am using Linux Ubuntu 20.04.02 LTS and ffmpeg 4.2.4.

    


  • How to merge/mix/overlay multiple videos, with time-shifts ? [duplicate]

    17 février 2021, par Basj

    How to merge/mix/overlay multiple videos, with time-shifts ?

    


    Example : I'd like to take :

    


      

    • 4 seconds of 1.mp4 and it should start at 0'10" in the output video

      • 


    • 8 seconds of 2.mp4 and it should start at 0'11" in the output video

      • 


    • 16 seconds of 3.mp4 and it should start at 0'12" in the output video

      • 


    


    They will be overlaying/overlapping themselves ; example : if 1.mp4 is 400x400, 2.mp4 is 200x200, and 3.mp4 is 100x100 pixels, then at 0'12" we will see the 3 videos at the same time, overlapping each other.

    


    ffmpeg -t 4 -i 1.mp4
       -t 8 -i 2.mp4
       -t 16 -i 3.mp4
       -filter_complex [0][1][2]overlay[out]
       -map [out]
       out.mp4 -y


    


    I see there is a overlay t parameter, but how to specify a different starting-timestamp for each video ?

    


    It seems we cannot use -itsoffset for multiple sources at the same time : https://trac.ffmpeg.org/ticket/1349
