We've been using OBS to record our church's sermons and am having problems getting both webcams and audio synced. We're also using it to show pre-service announcement slides and the service itself on a monitor in the foyer. We're trying to have this all automated as much as possible. We have it so OBS launches when the computer is logged into at around 8:30am Sunday. This is when the announcement slides will start showing. OBS is set up to start with that scene when it's opened. We use Proclaim software to show the announcement slides and song and sermon slides during the service. OBS uses a display capture source to capture the slides. We also have MIDI cues in Proclaim that can switch scenes in OBS using the MIDI plugin in order to use the 2 cameras at different times during the service. We use the Advanced Scene Switcher plugin to start recording when a certain slide is shown just before the sermon starts. The sermon usually doesn't start until around 11:00am, so there's about 2 1/2 hours between when OBS first starts and we start recording.
I set all the cameras and audio up so they are in sync before Sunday using a flashing and beeping video on my smartphone set on the stage so both cameras see it. The short test videos I record are all in sync, but the Sunday sermon recordings aren't. It seems that the sources are going out of sync during that 2 1/2 hours while OBS is on but not recording. What would cause them to go out of sync over this time? At one point I tried turning off the buffering in the webcam sources but they would both end up jerky. I also have the webcams to stay active even when not being shown. Do you think if I set them to deactivate while not shown it would somehow put them back in sync? When the recording starts the scene is switched to a blank (black) scene and fades into the sermon camera scene. If I have the webcams deactivate on this blank scene would it help the sync? Just asking before I try it this week.
Thanks.
