Signs it’s time
You don’t need all of these. Two or three is a strong hint.
- “Encoding overloaded” shows up during worship, when slides, motion backgrounds, and cameras are all busy. (See why OBS overloads during worship.)
- A slides problem becomes a stream problem. The slides app freezes and the whole computer, stream included, struggles with it.
- Someone clicked the wrong window and the congregation at home saw a desktop, a file browser, or a notification.
- One person runs everything, and you can’t find a second person willing to learn it.
- The same problem comes back every Sunday. (See a different OBS problem every Sunday?)
What the move involves
Less than most churches expect:
- A second computer for slides. A modest laptop is usually enough.
- A network cable to each computer, both on the same switch.
- The free DistroAV plugin in OBS, and NDI output on the slides computer.
Full steps: two-computer OBS setup for church.
Before you buy a bigger computer
Sometimes the streaming computer really is too slow. Often, it’s just doing too many jobs. Check what it’s actually doing first: CPU, graphics card, and dropped frames during a real service. (See the best computer for church livestreaming.) Moving slides off it may be the cheaper fix, and it creates a second volunteer seat at the same time.
What you get besides a steadier stream
- A seat a new volunteer can learn without touching OBS.
- A backup plan: if one computer restarts, the other keeps going.
- A path to three seats when you add PTZ cameras. (See the three-seat setup.)
Where WorshipMetrics helps
Tech Manager shows what your OBS computer is actually doing (CPU, graphics, dropped frames, and stream health) and alerts your team if the stream or recording stops. That makes it clear whether you need a second computer, a faster one, or a settings change. Send slides from Present over NDI with a transparent background, and ask Luminos or call 910-WORSHIP when you’re not sure which fix comes first.
Thinking about a whole new system instead? See should our church switch from OBS? and our Livestream Systems.
Related questions
- Should we run OBS and slides on the same computer?
- It works for small, simple services, but it's fragile: one computer does slides, switching, and encoding, and one person has to run it all. If you see encoding overload, slide crashes affecting the stream, or volunteers avoiding the booth, move slides to a second computer over NDI.
- Is a second computer cheaper than a faster streaming computer?
- Often, yes. A modest laptop for slides, sent over NDI, can relieve the streaming computer enough to fix overload problems, and it also creates a second volunteer seat. Sometimes both are needed; check what the streaming computer is actually doing first.
- What do we need to split OBS across two computers?
- A second computer for slides, a wired network connecting both, the free DistroAV plugin in OBS, and a slides app that can send NDI (or the free NDI Screen Capture tool).
