Streaming & recording
Recording
Set recording quality and destination, record with or without streaming, and find your files afterward.
On this page
This page covers recording settings, where the files end up, recording without going live, and what to do once a service recording is finished.
Recording settings
Settings → Recording
| Setting | What it does | Recommended |
|---|---|---|
| Save to | Folder where recordings are written | Default is ~/Movies; click the folder icon to pick a different location |
| Resolution | Recording resolution | 720p, 1080p, or 4K |
| Bitrate | kbps for the recorded file | 8000 for 1080p; KERYX bumps this to 30000 automatically when you switch to 4K |
Advanced
Settings → Recording → Advanced
| Setting | What it does | Recommended |
|---|---|---|
| Encoder | Software (x264) or Apple hardware | Apple hardware — it's the default, and offloads encoding from the CPU |
Recording is independent of streaming
Start Recording and Start Stream are separate buttons and separate processes. You can:
- Record without streaming at all — useful for a service you want on file but aren't broadcasting.
- Stream without recording.
- Do both at once, which is the normal Sunday setup.
Stopping one does not stop the other. If you only click Stop Stream, the recording keeps going until you separately click Stop Recording.
While either is active, the Stream Preview panel shows a pulsing red outline with a badge: LIVE if you're streaming, or REC if you're recording without streaming.
4K recording
Choosing 4K as the recording resolution requires the OBS engine (beta), set in Settings → General → Video engine, and a camera actually capable of feeding a 4K signal — the Standard (FFmpeg) engine doesn't support it. If your camera or capture device can't deliver 4K, you'll get a smaller output despite the setting.
Where files go and disk space
Recordings are written to the folder set in Save to — by default ~/Movies. Each service recording is its own file, named by date (2026-09-27-service.mp4, then -2, -3 for later services that day). Before a long recording session (especially at 4K), confirm there's enough free space on that drive: at 13 GB/hour for 4K, even a modest buffer disappears fast on a nearly-full disk.
What happens when you stop
Clicking Stop Recording ends the file and it becomes available in the Recordings screen, reachable from the toolbar. KERYX does not automatically open a trim/edit screen when you stop — the recording just finishes and sits in the list, ready whenever you're ready to deal with it.
From the Recordings screen you can:
- See every recording made on this Mac, with its date and file path.
- Click Trim & publish to open the trimmer on a finished recording and send it toward the podcast feed and YouTube. See Publishing for what happens after you trim.
- Click the folder icon to reveal the file in Finder.
- Click Import a file… to bring in a recording that was edited outside KERYX, so it can still be published through KERYX's pipeline.
Trim & publish is only enabled once the file exists on disk and the recording has actually finished (a still-recording session, or one whose file went missing, is grayed out).
