  • FFMPEG : Output tiles onto a black background [closed]

    14 juin 2013, par MollyRazor

    I have the following command, which converts a video and also generates a 10x9
    tileset. Currently it gets the longer side and either generate a 90px wide or
    45px tall tiles. My problem is that each tile has to be 90x45 large, so in
    essence what I need is a properly resized and centered tile inside a black
    bounding box. How can I achieve this ?

    The resulting tile

  • 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 :)
