DVD operation and insert requirements

The DVD is the most crucial part of the studio, without it there would be no VT inserts, openning titles, credits, stings, ect. However, the DVD has certain requirements that must be met for it to work perfectly. These include:

Constant screen ratio. This means that each insert should have be of the same height and width so that there is a smooth transaction between the live studio and each VT. We failed on this part and ended up with different sized VTs of varying quality.

You must have at least 7 seconds inbetween each VT. These 7 seconds comprise of a second of black screen, so that the VT will not be cut off if something is wrong with the timings in the studio. Next there is 5 seconds of one frame which shows the name, length and description of the VT so it is easy to distinguish which is which. The final second is made up of just a black screen so that the Director has time to inform the vision mixer when to cut to DVD.
