  • How to use ffmpeg to extracted every nth frame from a video to generate a shorter new video ? [duplicate]

    12 octobre 2022, par J.W

    For example, a video length is 60 seconds with 25 FPS, there are 25 * 60 = 1500 frames.
How to extract the 1st frame every 5 frames, i.e., for the first second's 25 frames, need to extract the 5 frames at 1st, 6th, 11th, 16th and 21st, so the result new video would have 300 frames in total, and at the same time keep the same FPS (or increase FPS) to make the new video shorter, for example :

    


      

    1. to keep the result video to be 25 FPS (same as original video), the video length is 12 seconds ; or
    2. 


    3. to make the result video to be 30 FPS, the video length is 10 seconds
    4. 


    


    Note : the answer in the comment of this similar question solved my question :

    


    ffmpeg -an -i in.mp4 -vf framestep=5,setpts=N/25/TB -r 25 out.mp4

  • I want to use C# to get the first frame of a video as a preview image of the video without using ffmpeg to achieve it [closed]

    19 avril 2023, par anton

    I have some video files here. My client asked me to edit and format these video files and some text content and display them. Of course, C# is required. Since ffmpeg has 100+ mb, it's too big. Is there any other alternative or other more portable three-party library ?

    


    I'm using ffmpeg now, but it's too big, it needs to be started from the command line, and it can't be packaged perfectly with fody.

    


    I wonder if there is a more lightweight or embedded way to replace it to get the first frame of the video as a preview of the video

    


    I'm using winform not WPF
