The Roland V-40HD Multi-Format Video Switcher is a true multi-format video switcher, meaning it doesn't require input sources to be matched to output resolutions. Every input has its own broadcast quality scaler that can individually scale, stretch, crop and zoom each source as needed for the output resolution chosen. A Multi-Zoom feature can be enabled when one video input is shared internally with up to three more inputs. The scaler for each input can zoom into any position in the video image to give the appearance that additional cameras are connected, thus creating a virtual multi-camera environment. LEDs indicate input status.
