Ingest

Live ingest records a live input into a file. A source is a capture input on a node (a Blackmagic card, any DirectShow capture device, or a test pattern while there is no card), the profile that encodes the recording and the folder it goes to. An armed source holds its card open and keeps the last seconds of picture and sound in the node's memory: its tile shows the live picture and the audio levels, a recording starts from that buffer (with pre-roll if the source has one), and signal loss and drops are shown as they happen. The buttons under each tile arm or disarm the source, start or stop a recording, and open its settings; click the picture for the large view. A source with NDI output is also on the node's network as NODE (name) while it is armed; its pill shows the connections it serves (most receivers open two, picture and sound). Every recording shows the bitrate it writes: the last ten seconds on the tile and in the table, the file's average in brackets. The tile also shows how much of the node's network link is in use — a link near 100% is why recordings fall behind and then drop frames. Tick sources and use Start selected (or Start all) to start them together: one common instant, each node begins with the frame nearest it in its buffer, so the files line up frame for frame; the Started cell's tooltip shows each file's first-frame time and its offset from that instant.
