A vision schematic is a visual map of what equipment you need for a vision system set up. It is a document that assists in determining the equipment required, the types, amount and length of cables and determines the specific connector types. They are used in briefing technical staff and set up.

When creating a schematic some tips include:

■   start with sources at the bottom

■   display devices at the top

■   add vision mixing equipment

■   add cables

■   add connectors

■   include audio equipment if required.

ACTIVITY

The teacher will set up a simple vision system in the classroom and as a class, you will create a vision system plan.

The sequencing, timing and speed of vision cues is important with either pre-recorded vision or live video feeds to ensure the synchronisation of all technical effects.

The standard procedures used include:

■  plotting

■  recording

■  modifying as required

■  operation of the cues.

With the use of a vision mixer you can preview all source inputs and pre-set the next image to be put on the main screen with transition effects.

Vision system information is recorded and used within the prompt copy and cue sheets for the stage manager, vision director and vision operators to follow throughout the production or event.

Throughout pre-production and rehearsals there is often the need to modify or update documentation, including cue sheets. It is important only authorised personnel complete the changes as it is important to ensure currency of version and the status of any amendment.

So who is allowed to make changes on cue sheets? What is the correct process?

Watch the video 'Grease live control room split screen' to see an example of calling video cues in a professional setting, revealing the sequencing, timing and speed required of an director when calling the cues.
