  • Using ffmpeg to increase framerate without changing duration [closed]

    11 février 2024, par sarunw

    I want to increase the video frame rate with FFmpeg.

    


    I found from this website, https://trac.ffmpeg.org/wiki/ChangingFrameRate, that I can use -r or fps filter.

    


    The doc said the output duration of the video would stay the same, but that is not the case in my test.

    


    What I tried so far.

    


    I got a video with a duration of 19 seconds at 1.45 fps (I took this number from the QuickTime app)

    


    After using these commands, fps become 30, but the duration becomes 1 second.

    


    ffmpeg -i <input /> -filter:v fps=fps=30 <output>&#xA;ffmpeg -i <input /> -filter:v fps=30 <output>&#xA;ffmpeg -y -r 30 -i <input /> <output>&#xA;</output></output></output>
