Recording Monitor provides a preview of your microphone and camera during a recording, to check audio levels and keep the camera shot correct. Additional functionality such as the duration of the recording is also available.
The Recording Monitor tracks the selected inputs from the ScreenFlow recording configuration. If you have disabled both the camera and microphone, the recording monitor will shrink to just a timer. The green striped header at the top of the recording monitor will change to red when a recording is actually in progress. This gives you quick visual cue that your recording is in progress. Both the timer and the Add Marker buttons are greyed out when nothing is recording. The timer text displays in white once the recording has started. You can set markers by clicking the Add Marker button.
Once you have completed your recording, any markers you have added will immediately be shown in the timeline. The markers are attached to the primary clip.
