Recording Program
Start and stop
Press Record to start saving Program, and again to stop. Recording runs independently of streaming: you can record without streaming, stream without recording, or both at once, and stopping one never affects the other.
The file
Program is recorded as a QuickTime file with your choice of HEVC (smaller, for a machine that can play it back), H.264 (opens on older editing machines) or ProRes, and 24-bit PCM sound. It is written in one-second fragments, so a crash or a power cut keeps everything up to the last second rather than leaving a file that will not open at all.
ProRes comes in four flavours: 422 Proxy, LT, 422 and HQ, from the smallest file to the best picture. It is quick to edit, and your Mac encodes it separately from the stream, so recording in ProRes leaves more room for streaming, replay and recording your inputs. It takes far more disk: a 1080p recording at 50 frames a second is about 34 GB an hour in Proxy and about 165 GB an hour in HQ. The recording settings show the figure for your Show. ProRes needs an M1 Pro, M1 Max or any later Mac; on a plain M1 it would load the processor instead.
Without the overlays
Switch on Record without overlays in the recording settings (the gear beside Record) to record Program as it is under the overlays: every overlay, and any source or replay you play as an overlay, is left out of the file, so the graphics can be put back, changed or left off when you edit. A source you cut to Program stays in, even one that is an overlay. Only the recording leaves them out: the stream, NDI, Blackmagic output and the external display carry Program as it goes to air. Fade to Black does not reach this recording, which keeps the picture while Program is faded out. The recording button says “without overlays” while it records, and the switch applies from the next recording.
Next
Cut marks mark where a long recording should be split while it records, and export it in pieces afterwards. Recording your inputs records each source on its own, before crop, colour or effects, alongside recording Program.
