ProPresenter live captions
Live captions for ProPresenter services
Put realtime sermon and service captions on screen alongside ProPresenter. LiveSubs turns the pastor's mic into clean on-screen text and sends it to a lower third, a second caption screen or your OBS and vMix livestream, run by one volunteer for a flat per-minute rate.
Setup
How to caption a service with ProPresenter
LiveSubs runs beside ProPresenter and feeds captions to the exact screen you want. Pick the route that fits your booth.
Run LiveSubs on the booth PC
Download and start LiveSubs on the same machine as ProPresenter, or a nearby PC on the network, and add minutes with a key.
Feed it the pastor's mic
Point LiveSubs at the mic feed coming into the PC, or any system audio, so it hears the same speech the room hears.
Choose where captions appear
Send a transparent caption layer over NDI or Spout to a second screen, or push live text over OSC into an overlay on your stream.
Position the lower third and go
Place the caption band where it clears ProPresenter's lyrics and lower content, then leave it running for the whole service.
Where captions go
Get captions on every screen in the room
ProPresenter owns the main screens. LiveSubs adds the caption layer wherever your congregation and remote viewers need it.
A dedicated caption screen
Send the transparent NDI or Spout feed to a side screen or monitor so hard of hearing members can follow the whole service without crowding the lyrics.
Lower third on the livestream
Drop the caption layer into OBS or vMix as an NDI or Spout source so your online viewers see burned-in sermon captions on the stream.
Over the ProPresenter output
Composite the transparent caption band on the same feed as ProPresenter in your switcher or OBS, keeping lyrics up top and captions along the bottom.
Multilingual congregations
The transcription engine handles many languages, so you can caption services and guest speakers for an international congregation.
Why churches pick LiveSubs
Built for one volunteer and a real budget
No monthly contract, no extra operator, no browser tab to babysit through the sermon.
One-volunteer operation
Set the audio source, press Start and it captions the whole service unattended. Your ProPresenter operator does not need a second job.
Pay per minute, not per month
A flat $0.04/min with no subscription. A one-hour service costs about the price of a coffee, and there is nothing to cancel over the summer.
Native app, not a browser tab
A Windows app that runs beside ProPresenter, so there is no Chrome window to keep focused and awake while the pastor is preaching.
Fits your existing rig
Captions go out over NDI, Spout and OSC at once, so they drop into ProPresenter workflows, OBS, vMix and most switchers without new hardware.
FAQ
Questions
How do I show live captions with ProPresenter?
Run LiveSubs on the booth PC alongside ProPresenter, feed it the pastor's mic or the system audio, and route the captions to where you want them. It sends a transparent caption layer over NDI or Spout for a second screen, or live text over OSC for an overlay, so ProPresenter keeps driving lyrics and slides while LiveSubs adds the captions.
Does LiveSubs replace ProPresenter or run alongside it?
It runs alongside. ProPresenter still handles your lyrics, scripture and slides. LiveSubs adds a separate realtime caption layer on a second screen, on the livestream, or composited onto the same output, so you keep your existing service flow.
Can one volunteer run this during a service?
Yes. Once the audio source is set, you press Start and it captions the whole service on its own. There is nothing to type or cue, so your ProPresenter operator or a single tech volunteer can leave it running from opening to benediction.
How much does it cost for a weekly service?
LiveSubs is prepaid and pay per minute at $0.04/min with no subscription. A one-hour service is about $2.40 of captions, and you only buy the minutes you use, so there is no monthly fee sitting idle between services.
Can I put sermon captions on our livestream?
Yes. Because the caption layer comes in as an NDI or Spout source, you add it to your OBS or vMix scene and it burns into the video your online viewers see, exactly like your other lower thirds and graphics.
Can it caption a guest speaker or a second language?
Yes. LiveSubs captions whatever audio you feed it, and the transcription engine supports many languages, so guest preachers and multilingual services are captioned the same way as your regular speaker.
