  • How to add black borders to video

    7 décembre 2023, par Arnaud Rochez

    So I'm using ffmpeg to convert a video to 19201080 px, I found two ways to do so, the first one would be to stretch the video to 19201080, but then it looks kinda stretched. I used this command for this :

    


    ./ffmpeg_darwin -i SRC -vf scale=1920:1080,setdar=16:9 DEST


    


    The other option is the same without setdar but this just adapts the resolution to the one it started from (1728*1080).

    


    I would like to fill the 192 pixels of the width with a black border. Is there some kind of option to do so ? Or is there maybe another command line that could achieve this ?

    


  • ffmpeg generate from png sequence produces black video

    20 septembre 2019, par friendlygiraffe

    I am using ffmpeg to generate an MP4 from a png sequence using the following :

    ffmpeg -framerate 25 -pattern_type glob -i "*.png" -c:v libx264 -pix_fmt yuv420p -b:v 1M out.mp4

    But it outputs a black video, any advise on why ?

    The folder contains 2000 pngs which are 4520 × 2160 pixels

  • ffmpeg : How to add frames or black at the end of a video ?

    10 mai 2012, par Jim Hoyle

    How to copy an arbitrary amount of duplicates of the last frame at the end of any video ? Or alternatively, how to add black frames at the end of any video ? Can this be done by scripting and ffmpeg ? Of course any other tool is fine, as long as the action is scriptable.

    The difficulty is that all video formats, or at least as wide range of video formats as possible, should be supported. The script should take in any video formats without manually changing the script per video.
