<h3>Transform 16:9 aspect ratio video into 4:3 with letterbox</h3>

This resolution independent formula is actually padding any aspect ratio into 4:3 by letterboxing, because the video filter uses relative values for input width (iw), input height (ih), output width (ow) and output height (oh).</dd>
