[FFmpeg-user] How to add black bars as replacement for height?

[Robin van der Linden]

Thanks for your reply, Moritz,

I now came to the following cmd:

-vf 
"scale={stream["width"]}:{stream["height"]}:force_original_aspect_ratio=decrease,pad={stream["width"]}:{stream["height"]}:(ow-iw)/2:(oh-ih)/2,setsar=1"

{stream["height"]} and {stream["width"]} are just placeholders


Thanks for your help.
