The following items are available for a live production.
Two JVC GY-HM790 3CCD HD shoulder cameras are available for manned operation. Intercom and tally are present so that the camera can be fully integrated in the live production. Vinten tripods are available with zoom and focus controller. A wireless video connection with a Teradek Bolt 2000 is available for the cameraman to be able to move freely.
The following remotely operated cameras are available:
- Sony BRC-Z330 CMOS pan-tilt camera, 5 available (3 black, 2 white), used also for underwater camera
- Sony BRC-Z700 3MOS pan-tilt camera (black)
- Panasonic AW-HE120K 3MOS pan-tilt camera (black)
- Bradley/BR-Remote HDC-160 CMOS pan-tilt camera
- Sony FCB-H11 CMOS, 1 available
Mounting options for the remote cameras are tripods and clamps.
The central point in the solution of videoregie.nl is the video direction rack. This table-high 19" rack on wheels contains all switching equipment, power supplies and data connections. Switching is done via a Blackmagic Design 40x40 SDI router and an Blackmagic Design ATEM 1M/E 4k vision mixer. Monitors and control panels will be place next to the rack. All camera control and switches are controlled from software to allow for efficient operation from a single location.
8 camera inputs are available and 8 other SDI inputs. 12 SDI outputs and 2 CVBS outputs available. The used format is 576i/50, 720p/50 or 1080i/50. All resolutions fits perfectly with LED screens and internet live streams/webcasts. The stream will be created in 720p/25 or 1080p/25.
The rack and accessories require at least 4m² floor surface and a table. Some extra space around the rack is needed during build-up. Finally take into account the equipment needs to be rolled into the venue.
Further equipment in the rack is:
- A UPS to be able to keep working during temporary power failures
- 2 Blackmagic Design Hyperdeck SSD recorders
- 4 composite video output converters
- A colour corrector to correct camera or LED screen colour problems (SD only)
Where possible the cameras are genlocked, synchronised. This reduces the delay from camera to output even further, so that the live images can be shown well on LCDs, projectors or LED walls. For comparison: a software based solution has a minimum of 4 extra frames delay, which is quite disruptive to watch. And an IP-camera will give you another 0.5 s delay.
When necessary also other connections can be realised. Various conversion devices are available, such as scalers and scan convertors, to perform amongst others the following conversions:
- VGA → SDI: to display standard VGA, with manually adjustment for perfect alignment
- DVI/HDMI → SDI: to display DVI/HDMI sources
- SDI → DVI: Can be used for example to adjust the output signal to the resolution of a LED wall
- SDI → HDMI: Can be used for example to connect HDMI monitors
- SDI down- or up-conversion (HD/SD)
The camera cable is a specially designed cable, custom manufactured. The cable contains all required connections and is thin enough to remain practical.
Every camera is connected via a connection box. This box performs a number of functions.
- Converts the camera cable plug to the plugs on the camera.
- Stabilises the power supply to compensate for to the voltage drop across the camera cable.
- Converts the video signal to SDI if the camera does not generate SDI itself.
- Shows a tally signal when appropriate.
- Allows for spoken communication by means of an intercom.
All video is transferred digitally via an SDI connection. This means that no quality loss occurs between the connectionbox and the central rack.
To all cameras a data connection is available in the form of an RS-232 or RS-422 connection.
A blackburst signal is available to synchronise the cameras (genlock).
All cameras are fed with a low voltage and watertight connectors have been used, so that the cables are safe in an environment with moisture or water.
A number of microphones and a small digital mixer mixer are available. Other audio equipment available at the event can be connected via a DI-box. This is often the best solution to record a presentor/announcer and locally played music well.
The audio will be embedded in the outgoing SDI signal, so that the sound can also be heard on videomonitors elsewhere in the venue.
