Hallelo Studio for Mac
A whole control room, on one Mac.
Cameras and phones in; switching, graphics and sound; checks before you go on air; one programme out to Hallelo Live. The engine runs on its own, so the service keeps going even if the window closes.
In
Everything you have, in one place.
Studio takes in whatever your church already owns, and the phones in everyone’s pockets.
Cameras and capture cards
USB and capture-card cameras, Continuity Camera, and the Mac’s own screens.
Over the network
SRT (listening or calling, encrypted), RTSP, HLS and WHEP, with as little as 0.12 s of delay.
Phones
Every iPhone and iPad running Hallelo Stream, picture and sound, with tally.
The library
Clips, stills and music from your library, and other Hallelo Live channels as feeds.

Try the desk
Switch a service. Right here.
This is Studio’s switcher, working. Cue a camera to preview, then cut, mix, dip or wipe it to air. Put up a name, a verse or a countdown, and fade to black at the end. Every church is different, so choose one.

Programme loudness, as Studio holds it
In Studio this runs in 1080p on the Mac, with four downstream keys, scenes and stingers, and the engine keeps sending even if the window closes. Here it runs on example pictures in your browser.
Before you go on air
Six checks, then a countdown.
Studio looks at the picture, the sound, the keys, the connection, the clock and the disk before it lets you go live, so the first minute of the service isn’t the one you find out.
- Picture: waitingProgramme has a picture, not black or frozen
- Sound: waitingProgramme has sound, at a sensible level
- Keys: waitingNothing left on screen from last week
- Connection: waitingHallelo Live is reachable, with room to spare
- Clock: waitingThe Mac’s clock is right, so the countdown is
- Disk: waitingRoom to record the service locally as well
- Checking…

The service starts in 04:59
St Mary’s · Morning worship
If the connection struggles, Studio falls back to your backup key, and it records the service on the Mac either way.
Graphics
100 themes. Twenty ways on.
Names, verses, the CCLI licence line, countdowns, clocks and tickers, in looks made for the church year. Choose one below and watch it play on, the way Studio does.

Sound
A sound desk that listens to the service.
The sermon is clear, the band sits right, and the people at home hear what the people in the room hear.
Up to 32 strips
Every microphone, instrument, phone and clip, each with EQ, a gate, a compressor and delay.
Sound follows the picture
Cut to the pulpit and its microphone comes up. Music ducks under the voice by itself.
Mixes for the room
Four aux and mix-minus buses, for the band’s monitors, the hearing loop and the overflow room.
Even at home
Loudness held at −16 LUFS by EBU R128, with a limiter at −1.5 dBTP, so no one reaches for the volume.
In the room
Screens for everyone who needs one.
The volunteers at the back, the preacher at the front and the people in the overflow all see what they need.
The programme on the projector
Put what’s going out on a screen in the room, so the overflow sees what home sees.
A stage display
The clock, the countdown and what’s next, where the preacher can see them.
A control wall
The multiview, scopes and the on-air clock on any screen you have.
Dark-room mode
Dimmed for the back of a church at evensong, so the desk doesn’t glow.
Replay
The last ten seconds, again, at the press of a key.
In your volunteers’ language
Studio’s menus come in 44 languages and regional versions, from Brazilian Portuguese to Korean.
Control
Buttons under your fingers.
Run the service from a key pad, a MIDI controller or a lighting desk, and let Studio light every camera’s tally and move the robotic ones. Try the pad: it works the same desk as the rest of this page.

Stream Deck is Elgato’s; Hallelo Studio works with it directly. Control surfaces come with Studio for the Mac.
What it needs
A Mac with Apple silicon.
Studio runs on any Mac with an M1 or later and macOS 26. To send 1080p you’ll want about 10 Mbps of upload. Studio sends to Hallelo Live, which takes the service to your website, the app, on demand, radio, and YouTube and Facebook.
Make every service beautiful.
Hallelo Studio and Hallelo Stream are coming soon. Tell us about your church and which platforms you use, and we’ll bring you in early.
