Using VMix with Google Plus hangouts requires the input to be 640 x 360 rather than render the output to the external output to 640 x 360. The SD version allows 640 x 480 capture, but it should also allow capture at the 640 x 360 aspect ratio (and the 1.777 aspect ratio should be supported up through the 768 x 576 resolution) as web cams will support capture at the 1.777 aspect ratio (specifically webcams like the Microsoft LifeCam Studio and the Logitech C920)
When selecting the capture resolution the aspect ration of 640 x 360 isn't available in the list of choices. It would be great to be able to capture at that aspect ratio.

Thanks
