QLab 5.6.3 Mac download

QLab is a macOS application used to design and run sound, video, lighting, and show control cues.

Its main job is cue sequencing. You build a list of cues, set timing, and trigger them live during a show. Audio and video faders sit right on the interface, so you adjust levels without leaving the workspace. For video, you get keystone correction and corner pinning — useful when projecting onto angled surfaces. You can also pull live input from external devices like Blackmagic hardware, reverse or center a video on a projector, and overlay titles on top of playback.

Effects matter too. QLab includes audio and video effects, plus Syphon integration for sending video to other apps. Animation tools handle movement and scaling. Since audio, video, MIDI, and OSC all live in one workspace, you coordinate lighting and sound from a single timeline.

A real-world scenario: corporate AV installations

I set up QLab for a museum's permanent exhibit last year. The loop had to run eight hours a day, seven days a week, with no operator. Video projection onto three angled walls, synchronized audio through six ceiling speakers, and a lighting cue triggered by a motion sensor at the entrance. QLab handled the whole thing from one Mac Mini. No interface, no separate lighting console. The built-in keystone correction and corner pinning saved me a full day of aligning projectors. The 48 audio outputs covered every speaker zone without extra hardware. For a qlab crack, you get the same feature set — no missing pieces in the install.

That kind of installation works because QLab doesn't need a live operator after setup. You create a cue list, set it to loop, and let it run. The workspace stores everything: cues, timing, device routing. If the museum changes the exhibit layout, I reopen the file, adjust a few video cues, and that's it.

Workflow: building a basic audio-visual cue stack

Here is a start-to-finish workflow for a simple two-minute show with audio and video.

1. Open QLab and create a new workspace. The default view shows an empty cue list.
2. Add audio cues by dragging WAV or AIFF files into the cue list. Trim the start and end with the integrated audio editor so the track starts exactly on the beat.
3. Add video cues the same way. Drag a video file below the audio cues. Use the centering tool to place it correctly on the projector, then apply corner pinning if the projector is angled.
4. Set each cue to Auto-Follow or set a time delay between cues so they play in sequence without manual triggering.
5. Add a fade cue at the end of the list, set to fade audio and video levels to zero over three seconds.
6. Test the stack in cue-list mode. Adjust timing for any overlap.
7. Export the workspace or copy it to the show machine. Launch QLab, open the file, and press Go to start the sequence.

The same workflow works for longer shows with hundreds of cues. Undo handles mistakes during setup.

Misconfiguration warnings now color rows

Three small changes that affect the daily work of a lighting programmer or show control operator.

• Rows in the Light Library or Light Definition editor now change color when an instrument definition in the row is misconfigured. You see the problem immediately, not after a failed cue.
• The Light Patch editor shows a Broken status for a misconfigured instrument definition. No more hunting through patch lists to find the bad channel.
• Workspaces created in 5.6.2 and earlier migrate automatically to use the built-in network device definition for Right On Cue Services Stage|Tracks. That saves a manual configuration step after updating.

The update also fixes a rare crash that could happen when stopping video playback. If your show uses a lot of video cues, that alone is worth the upgrade. The rest of the install stays the same: mount the disk image, bypass Gatekeeper in Terminal, drag to Applications, and launch.
