<p>I will soon be in charge of multiple screens for scene at a concert. Those screens are centralised and a video output will be give to me. I'am looking for a way to divide this video output into two virtuals parts in my computer. The top part and the rectangle at the bottom.</p>

<p>The goal is to show different visuals on the two parts.</p>

<p>Thank you for your help</p>

Need concrete details. Input format? Output format? Tools/software available? Do you need to rescale parts of the input to form the rects at the side & bottom. Like I said, some concrete details.

I will soon be in charge of multiple screens for scene at a concert. Those screens are centralised and a video output will be give to me. I'am looking for a way to divide this video output into two virtuals parts in my computer. The top part and the rectangle at the bottom.
