FAQ

Each Cue 1 video showfile contains video content and a programmed Qlab 5 file. Video outputs have to be mapped in the settings on your show computer. Ensure video outputs are setup correctly, and make sure the test patters at the beginning of the file are outputting correctly.

All video files are 1920x1080p 60 fps, these video files and have been meticulously programmed into Qlab using the official scripts and score so they are ready to go from day 1 of your production and work perfectly with the script.

What do I need to operate a show with a Cue 1 showfile?

To get the most out of your Cue 1 showfile, you’ll need

  • An Apple computer with Qlab installed,

  • A Qlab video license available for rent for minimum $5/day at https://qlab.app/

What if I don’t have an Apple computer to run the show on?

The showfiles are designed to be easily operated with Qlab straight out of the box, however all the video files are included in a “video” folder so you could assemble your own showfile with the video files we supply. Keep in mind this may take a long time and the raw video have been rendered and optimised for our workflows and may not be best suited for creating your own files.

If you’re having particular issues with the content in your showfile please email our team below

Front‑projection

  • Definition: The projector sits in front of the screen and bounces light onto the reflective surface, which then returns the image to the audience. It’s the most common setup in theatre projection.

  • Typical placements:

    • From a booth or into the audience (long‑throw)—most common, but shadows from performers are likely

    • Hung high (e.g. on a lighting bar or grid) with short‑throw or ultra‑short‑throw lens to project over actors and avoid shadows.

    • Onstage behind set pieces (if using ultra‑short throw), though it risks occlusion.

  • Pros: Brightest image / easiest screen setup / minimal screen space needed.

  • Cons: Shadows, potential for actor “blocking” projection, lighting spill interfering with visibility.

Rear‑projection

  • Definition: The projector operates behind a translucent scrim and casts the image through to the audience side.

  • Mounting options:

    • On the floor behind the screen (leads to backstage “no‑go‑zones” through the beam).

    • Hung above/behind an upstage bar (avoids beam interference but requires rigging space).

  • Pros: No shadows or actors blocking the image, and no visible projection hardware from audience view.

  • Cons: Requires specific screen material/translucency, space backstage, and sometimes more complex screen frames.

Front projection is easiest but needs careful placement and control of ambient light; rear projection avoids shadows at the expense of more space and a special scrim/mesh.

Approximate benchmarks:

Venue size / screen focus

Rule‑of‑thumb brightness

Small venue (~150 seats) ~3,000 - 5,000 lumens

Mid‑size theatre (~300 seats) ~5,000 – 6,000 lumens

Larger stages (wide cyc, visible from upstage) ~8,000 - 10,000 lumens
