Video Exporter Node

Hello,
please, can someone show me an example how to use the Video Exporter node from the Post-FX/Image Processing section? Would be very helpful.

Thanks
Jo

What goal are you trying to achieve?

The first thought was, I can use this node to render out the viewport in parallel.

Second, when I see a node, I want to figure out what can you do with it.

Then I think your first stop should be the manual, as it often has examples of how individual nodes are used.
