In HD, Apollo can record up to five tracks of video simultaneously. One, two three or four HD video signals can be input simultaneously. One of these inputs can be over HDMI or up to four inputs can be over SDI. On a fifth video track, Apollo can also record a Quad-Split view of the four inputs or a Live-Switch between the four inputs. When recording the Quad-Split or the Live-Switch, the original four inputs are always also recorded.
In 4K, Apollo can record up to two tracks simultaneously.
