         <dt>layout=0_0|0_h0|0_h0+h1</dt><dd>This is where the locations of the video sources in the output stack are designated. The locations are specified in order of input (so in this example <code>0_0</code> corresponds to input <code>[a]</code>. Inputs must be separated with a <code>|</code>. The two numbers represent columns and rows, with counting starting at zero rather than one. In this example, <code>0_0</code> means that input <code>[a]</code> is placed at the first row of the first column in the output. <code>0_h0</code> places the next input in the first column, at a row corresponding with the height of the first input. <code>0_h0+h1</code> places the final input in the first column, at a row corresponding with the height of the first input plus the height of the second input. This has the effect of creating a vertical stack of the three inputs. This could be made a horizontal stack by changing this portion of the command to <code>layout=0_0|w0_0|w0+w1_0</code>.</dd>
