4. Finally select Input 1 at the program bus, the clip starts to play and is
switched to the PGM out put of the PP stage. Depending on the type of
server used, it may be possible that you see a freeze frame at the
beginning of the clip. This can be prevented by setting up a preroll time.
Open the
Input menu (040102) and set the preroll time in the preroll tab
for the used input to 2 or 3 frames, depending on the reaction time of
the used video server. The preroll time is calculated in
Fields ! Switch to
another input, load the clip again, and switch to input 1. Now you
should see the playing clip without a freeze frame at the beginning. If
not, increase the preroll time to your requirements. The main function
of preroll is to delay the switching of the source to the program output,
using the
Program , Cut or Auto button. The Transition Bar cannot be
delayed. Assigned events will be executed directly, in this case the Play
command for the video server.
5. Enable trigger Preset Bus is used to start the video server by using the
Cut or Auto button, or Transition bar at the transition module, if enabled.
Input 1 needs to be preselected at the preset bus. Enable transition/cut
trigger key bus is used, for example, if the video server is used as a key
source, or used in combination with a DVE effect.
