<p>Pad without specifying pad width, just put the input video in the middle of the output: pad=1920:1080:(ow-iw)/2:(oh-ih)/2</p>
<ul>
<li>ffmpeg: Calls the program ffmpeg</li>
<li>-i: for input video file and audio file</li>
<li>-c:v libx264: encodes video stream with libx264 (h264)</li>
<li>-pix_fmt yuv420p - creates YUV colorspace, progressive scan</li>
<li>-filter:v: calls an option to apply a filter to the video stream. scale=1440:1080, pad=1920:1080:240:0": does the math! resizes the video frame then pads the area around the 4:3 aspect to complete 16:9.</li>
<li>-vf yadif: deinterlaces the file (optional)</li>
