  • Vertical video play does not sync with multiple stacked video

    5 novembre 2018, par Sabha

    I dont know if I have wrote the subject well and if that can be understood. Nevertheless, here is an explanation

    I have 7 videos of different dimensions where the width is same (1080). I wish to place them one below the other to get a full hd vertical video (1080x1920). I tried the -filter_complex vstack filter in ffmpeg and got all the videos aligned one below the other and I am getting a perfect 1080x1920 full hd vertical video but they dont sync with each other. Once the videos are in sync, I need to put an audio too which should also sync with the in-sync video that will be made.

    There is so much of complexity. Please advice how do I make them sync. Is there any software that can allow me to put 7 videos one below the other in a timeline ? (if not 7, atleast 3-4 videos). Please advice where and how to start.

    Is there any option in Adobe Premier or any other software ?

    Thanks

    EDIT : I am doing a very long procedure to combine all 7 videos vertically

    first i use

    ffmpeg -i video1.mp4 -i video2.mp4 -preset veryslow -filter_complex vstack video12.mp4

    and then

    ffmpeg -i video12.mp4 -i video3.mp4 -preset veryslow -filter_complex vstack video123.mp4

    so on and so forth

    Is there a better way to do it all in one command ?

  • how to check the number of duplicated frame for video 1sec ( about 30frames ) from video start and want to apply this for mpdecimate

    20 octobre 2018, par cool jobs

    How to check the number of duplicated frame for video 1sec ( about 30frames ) from video beginning point ? I want to apply this for mpdecimate with audio. Some videos have three duplicated frames, some videos - 15 duplicated frame, some videos have 19 duplicated frames.. so it looks I need a variable or math operator in ffmpeg as expression.

    1. some video have duplicated frames at beginning point , but it is
      not same always the number of duplicated frames.
    2. if get back variable which is for the number of duplicated frames
      from step-1 then split and trim apply mpdecimate with audio as
      much as step-1 variable returned, finally do concatenate each other.

    Is this possible with -filter_complex for one line ffmpeg command ?

  • FFMPEG merging audio and video to get resulting video

    26 septembre 2016, par King

    I need to merge audio and video using ffmpeg so that, it should result in a video with the same duration as of audio.

    I have tried 2 commands for that requirement in my linux terminal. Both the commands work for a few of the input videos ; but for some other input_videos, they produce output same as the input video, the audio doesn’t get merged.

    The commands, I have tried are -

    ffmpeg -i wonders.mp4 -i Carefull.mp3 -c copy testvid.mp4

    and

    ffmpeg -i wonders.mp4 -i Carefull.mp3 -strict -2 testvid.mp4

    and

    ffmpeg -i video.mp4 -i audio.wav -c:v copy -c:a aac -strict
    experimental output.mp4

    and these are my input videos -

    1. samplevid.mp4

    https://vid.me/z44E

    duration - 28 seconds

    size - 1.1 MB

    status - working

    And

    1. wonders.mp4

    https://vid.me/gyyB

    duration - 97 seconds

    size - 96 MB

    status - not working

    I have observed that the large size (more than 2MB) of the input video is probably the issue.

    But, still I want the fix.
