SCS sending Cues to QLAB and playing videos to another VP

[mwfr]

"Head in the Stars" is a play that is currently being played in Paris (FRANCE) at the Théâtre de la Gaîté Montparnasse.
The action takes place in a space shuttle.
The piece begins with a video of the newscast broadcast by a projector on the balcony, then the curtain opens on the inside of the Space Shuttle, with a bay window 4 meters wide, on which are broadcast for 90 minutes, images of the earth, filmed from the international space station ISS. These images were provided by the European Space Agency, after a month of discussion, this is the first time that the Space Agency agrees to be partner of a show, and we are very proud )

I had to choose a very reliable broadcasting system, and meeting several requirements:

• Broadcast videos on a video projector positioned on the balcony, 30 meters away from the technical room.
• Broadcast videos on a video projector positioned on stage, located 40 meters from the technical room.
• Play over 100 Audio Cues.

The theater wanted to use QLAB, but it was impossible to do everything with it.
I personally preferred to use SCS, as a convinced user of SCS for 10 years, preferring it to its competitors on PC or MAC.
(I find it much better suited to the theater).

I also had to take into account the fact that the show will go on tour in theaters where the direction will probably be even further away from the stage.
And it was necessary to stay in the theater bugets, that is to say the most economical possible.

So I chose to use a PC and SCS as the core of the system.

1. The videos of the balcony projector by SCS and the HDMI video output of the PC (As the distance is 30 meters, I used a BLUESTREAM converter HEX70B-KIT http://www.blustream.co.uk/hex70b-kit and a 30 meter Ethernet cable category 6 to the video projector of the balcony and an OPTOMA EH504 5000 lumens
2. The videos of the video projector on stage are broadcast by a MAC and QLAB located behind the scenes. QLAB is controlled by SCS with Control Send Cues via a 30-meter Ethernet cable category 6. (It is important to use a category 6 Ethernet cable, with a lower quality cable, from time to time, the 'Contol Send' Cue was not taken into account by QLAB. This issue has been resolved once a category 6 cable has been used. For the tour, in some rooms do not allow to pass an Ethernet cable, we will use a WIFI TPLINK AC 1750 router (it is powerful enough for distances), to send the Control Send Cues to the Mac.

3. Audio Cues (over a hundred) are broadcast by SCS and a TASCAM US-16x08 sound card, with 8 separate outputs, and very economical. http://tascam.com/product/us-16x08/

The video projector on stage and an OPTOMA ZH400UST Laser technology 4000 lumens with a ratio of 0.25, which means that by placing the projector at 1 meter from wall, we get an image of 4 meters wide in full HD.

To take no chances, I used another PC with SCS and the same session, which I connected to the network with a HUB.
I doubled the 'Control Send' to MAC / QLAB of all the videos, by creating hotkeys, to be able to trigger them on the fly, in case the Manual Cue does not would not work (but it never happened )

Tips for playing videos with SCS:
SCS prefers WMV (Windows Media Video) format to MP4

Tips for CONTROLLING QLAB and MAC with SCS:

Assign a fixed IP address to the PC using SCS

The MAC must also have a fixed IP address. QLAB can then receive OSC (Open Sound Contol) Control Send Cues on port 53535

SCS must be configured as follows:

Editor / Production Properties / Devices / Control Send
Remote Device: Any Device or Product
Network Protocol: UDP
Network Role: SCS is a Network Client
IP Address or Server Name: (IP address of the MAC)
Port No.: 53535 (QLAB is basically configured to receive OSC messages on this Port)
_________________________________________

SCS 'Control Send' Structure:

In EDITOR / Cue / Add 'Control Send' Cue

Create a 'Control Send' Cue

Control Send Device: udp
Entry Mode: ASCII
Network Message: /cue/1/start
(This message starts cue 1 in QLAB session)

In Network Message box, you can send different OSC messages to QLAB
In example:

/go
/stop
/pause
/abstract
/Playhead/1
(this message places QLAB cursor head on Cue ('1') without playing it)
/Playhead/next
/Playhead/previous

Well, I hope this will help you or give some ideas to some of you.

Thanks for sharing. The Qlab control info is very useful.
