  • how to combine several video random any one to create 1 new video ? using ffmpeg ? [closed]

    28 juillet, par Sky Moon

    how to combine several video random any one to create 1 new video ?
for example, I have 10 videos : 01.mp4 ; 02.mp4 ... 10.mp4
I want to combine random 5 of them to create 1 video
example :
 (01.mp4+ 03.mp4+ 04.mp4+ 06.mp4 + 08.mp4) = 1 new video

    



    (02.mp4+ 04.mp4+ 05.mp4+ 06.mp4 + 09.mp4) = 1 new video

    



    Similar : random combination of 50 videos of 1000 videos to create 1 new video ?

    


  • Convert video.ts file into video.mp4 using ffmpeg

    11 juillet 2020, par HorizonBloom

    So I tried to convert a file named video.ts into video.mp4 in Python and am getting the error :

    


    FileNotFoundError: [WinError 2] The system cannot find the file specified

    


    Assuming video.ts is already loaded into the program and subprocess already imported.

    


    This is due to the line :

    


    >>> subprocess.run(['ffmpeg', '-i', 'video.ts', 'video.mp4']) but I don't know what's the problem.

    


    I've opened the video.ts file and it seem to be working fine. Python version (3.8.2)

    


  • How to know the delay of frames between 2 videos, to sync an audio from video 1 to video 2 ?

    8 janvier 2021, par jaimepm

    world.

    


    I have many videos that I want to compare one-to-one to check if they are the same, and get from there the delay of frames, let's say. What I do now is opening both video files with virtualdub and checking manually at the beginning of video 1 that a given frame is at position, i.e., 4325. Then I check video 2 to see the position of the same frame, i.e., 5500. That would make a delay of +1175 frames. Then I check at the end of the video 1 another given frame, position let's say 183038. I check too the video 2 (imagine the position is 184213) and I calculate the difference, again +1175 : eureka, same video !
The frame I chose to compare aren't exactly random, it must be one that I know it is exactly one I can compare to (for example, a scene change, an explosion that appears from one frame to another, a dark frame after a lighten one...) and I always try to check for the first comparison frames within the first 10000 positions and for the second check I take at the end.
What I do next is to convert the audio from video 1 to video 2 calculating the number of ms needed, but I don't need help with that. I'd love to automatize the comparison so I just have to select video 1 and video 2, nothing else, that way I could forget forever virtualdub and save a lot of time.

    


    I'm tagging this post as powershell too because I'm making a script where at the moment I have to introduce the delay between frames (after comparing manually) myself. It would be perfect that I could add this at the beginning of the script.

    


    Thanks !
