  • Remove .mp4 video top and bottom black bars using ffmpeg

    9 septembre 2014, par rexhin

    I’m new to ffmpeg and I have heard that it has a filter for black. I want to remove black bars on top and bottom of the video so the video will be cropped to the remaining video without black bars. Thanks :)

  • ffmpeg auto crop black frame and watermark

    4 juin 2018, par rbarab

    We are processing short videos. Most of them are 640x480, recorded by mobile. Many of them have a black frame on left and right.
    I would like to watermark the videos and currently using this command.

    ffmpeg -i IN.mp4 -i WATERMARK.png -filter_complex "overlay=main_w-overlay_w-10:main_h-overlay_h-10" OUT.mp4

    The problem is that if there is a frame, part of the watermark goes on the frame and only a part is on the actual content. Would like to place the watermark on the bottom right of the actual content.

    Are any of these possible, or any other ideas ?

    a, Dynamically detect the black frames and adjust the watermark position accordingly.

    b, Crop the black frame and watermark the content correctly in the same step.

    Thanks a lot for your help !

  • ffmpeg how to remove black borders when resizing an image

    3 juin 2021, par Mapg

    I am creating some thumbnails using FFmpeg and I see that some black borders are created when I resize them.

    


    I guess this is happening because the video source dimension doesn't match exactly the target dimension, so FFmpeg fills out the blank space with this black color.

    


    My question is ...

    


    Can I change this "black color" used by FFmpeg by default so I can match these extra borders added with the background of my application ?

    


    If this is not possible ...

    


    Can I convert these black borders to a transparent area so I can create a PNG to match my background which has a different color (a kind of light green)

    


    I have attached an example where you will see two black pixels height in the bottom zone of the picture.

    


    This is what I want to convert to transparent or being able to choose my own color.

    


    Any idea to solve this issue will be very helpful for me ?

    


    Thank you very much in advance !
