10.3 Commands

To enable frame accurate handling of clips, it is necessary to preload the next scene by

using the CUE command:

SCENE*<Scene Name> CUE

Because the loading time of clips is affected by disc speed and the used codec, allow at

least 1 second head start for the CUE command. The earlier you cue the next scene the

more likely all of the clips are prepared when needed.

After the initial CUE command it is/could be necessary to send the following

commands. If the scene was saved at another position than 0 send:

SCENE*<Scene Name>*STAGE SHOW 0.0

The following is always needed to finally set and activate the scene:

RENDERER SET_OBJECT SCENE*<Scene Name>

If the director is not configured to auto start you should use:

MAIN_SCENE*STAGE START

Note: The first and last commands are optional
