Configure frame size
By default, for channels with only one layout and when that layout has only one video source, your
Standalone VGA Grid automatically uses the incoming source frame size as the stream frame size. Frame size
greatly affects the amount of bandwidth needed to transmit your stream. The larger the frame size, the more
bandwidth you need to stream it. So you may want to keep the frame size the same as your source, or you
may want to apply upscaling, downscaling, stretching, or black bar framing, depending on your needs.
