I am trying the padding option using ffmpeg, but I am getting an error.

I am following this tutorial. Here's the error:

Unrecognized option 'padtop 120'.
Error splitting the argument list: Option not found

Try it this way instead:

 ffmpeg -i input.avi -vf "pad=width=640:height=480:x=0:y=120:color=black" output.avi  

The video filter syntax is the new way to use padding. Here the video output width and height are 640x480 and the image is placed 120 pixels from top, 0 pixels from left. To work out your exact dimensions, just apply the same principles.

See the pad video filter documentation for more details.

  • Rajib i might be a stupid question, but i need to add also for portrait video so how can i do it. Is it works for only landscape. I tried it for portrait but not happening properly. – Gururaj Dec 19 '13 at 13:10
  • @Gururaj You should post the exact dimensions of the "portrait" video, the exact dimensions of the output ("frame") video. I'm not sure, but I think you can add it to your main question itself by editing. – Rajib Dec 19 '13 at 14:51
  • Rajib i have a portrait video of dimension 400*800 i want to add padding to make this as a square video. What command I should pass?. Please provide sample command for this particular dimension video. – Gururaj Dec 20 '13 at 6:55
  • @Gururaj only a guess but I think the vf parameter for you (assuming you want it horizontally centered with black padding on the sides) would be: -vf "pad=width=800:height=800:x=200:y=0:color=black" (y=200 because that's the extra 400 px padding / 2) – r_alex_hall Aug 28 '19 at 0:35
