Console discovery
Finds Eos and QLab on the network. If the connection to the desk drops, it reconnects.
Show-Overlay
by Louis Haywood
Show-Overlay records your stage cameras and puts the live Eos cues, QLab cues, timecode, your own OSC fields and a watermark on the picture. When you watch it back, you can see which cue was running at any moment.

Getting connected
Plug in a camera and open the app. It looks for Eos and QLab on the network by itself.
Up to four cameras
Each camera records to its own file with its own label, and all of them show the same cue data. Sound is recorded with the main camera.
Movable widgets
Put each widget where you want it and save the arrangement as a layout. Switch layouts with a click or over OSC.
Eos cues and parts
Each cue shows its list and number. In a multipart cue, every part has its own bar that fills as it fades, with a countdown in milliseconds. If you stop a cue on the desk, its bar stops too.
- OSC 1.1 or 1.0
- Follows pause and resume on the desk
- Shows the next cue

Cue log
Each recording is saved with a CSV file, which opens in any spreadsheet app, listing every cue, part and marker with its recording time and timecode. You can use it to find a moment in the recording without scrubbing through it.
- Timecode from a running QLab Timecode cue
- Add markers in the app or over OSC
NDI and browser viewer
Send the finished picture over NDI to a vision mixer or OBS. NDI needs the NDI runtime on the Mac, which comes with the free NDI Tools. Anyone on the same network can also watch the picture in a web browser.
Custom fields
Show any OSC address on the picture with your own label, for example a sound cue labelled “Sound”. You can also start and stop recording, add markers and change layouts over OSC from QLab or Companion.

Updates
The app checks for new versions and installs one when you click Install Update. Updates are signed, and the app only installs updates signed by the developer.

Installing
Show-Overlay isn't notarised by Apple yet, so the first launch needs an extra step.
- 1
Download
Download Show-Overlay and open the zip file.
- 2
Move to Applications
Drag Show-Overlay into your Applications folder.
- 3
First launch

Permissions
Allow access to the camera, and to the microphone if you're recording sound.
About the first launch
macOS blocks apps that aren't signed with an Apple Developer ID and notarised by Apple until you allow them in System Settings. You only need to do this once. After that, Show-Overlay opens normally and updates install without the extra step.
Eos setup
Turn on Third Party OSC in the menu below. Show-Overlay then finds the console automatically.
