5. Make sure that the EDIT-ON/EE-ON delay time for your edit controller matches the

delay time set by VST controls.

Changing the Clip Loaded in a Sony Controlled Logical Unit

The Sony deck control protocol was originally developed to control VTRs, thus it has no

facility for clip management operations including the loading and unloading of clips.

The control vtr.control.clip.name can be set to change the clip currently loaded.

The GUI application mcclips (see “The Clip Manager” in Appendix A for more

information on mcclips) enables you to load and unload clips on ports controlled by

the Sony protocol. To load a clip, for example, follow these steps:

1. Select a clip.

2. Select File > Load On Port.

You can also create a new clip on a port:

1. Select a clip.

2. Select File > Create On Port.

An application can load a new or existing clip onto the units controlled by a Sony

protocol device by using the MVCP SSET command to set the value of

vtr.control.clip.name (see the vst-controls(5) man page).

Conﬁguring the SGI Media Server to Control a VTR

The SGI Media Server provides frame-accurate control for a VTR or VTR-like device that

supports the industry-standard Sony compatible VTR RS-422 control protocol. The VTR

can be controlled interactively through a user interface or through an application for

frame-accurate captures and laydowns of clips. To conﬁgure the SGI Media Server to

control a VTR, follow these steps:

1. As root, enter the following to verify that the vst_eoe.sw.diaquest subsystem

is installed:

# /usr/vtr/bin/vtrswinfo -subsys -short
