1. Introduction
VideoCreator allows you to record high-resolution images
generated by IRIS workstations onto standard or professional
videotape. You can record single images in a frame-by-frame
recording mode to produce computer-generated animation, or
capture (to videotape) a scan converted version of the
workstation's high-resolution video signal in real time.

2.2 VideoCreator_Subsystem_Disk_Space_Requirements
This section lists the subsystems (and their sizes) of the
VideoCreator software:
If you are installing this software for the first time, the
subsystems marked ``default'' are the ones that are
installed if you use the ``go'' menu item. To install a
different set of subsystems, use the ``install,''
``remove,'' ``keep,'' and ``step'' commands in inst to
customize the list of subsystems to be installed, then
select the ``go'' menu item.
Note: The listed subsystem sizes are approximate. Refer to
the IRIS Software Installation Guide for information
on finding exact sizes.
Subsystem Name Subsystem Size
(512-byte blocks)
vc.man.diags 40
vc.man.relnotes (default) 14
vc.man.vc (default) 200

3. Configuration_Information
If you have a PAL format VideoCreator, create a setup file
in the distribution directory (/usr/video/vc) or in your
home directory. This setup file tells the VideoCreator
software that the default video format is PAL. Refer to
Chapter 1 in the VideoCreator Programmer's Guide for
information on the setup file.

4. Bug_Fixes
The following VideoCreator bug was corrected in this
release. The description is followed by a Silicon Graphics
bug report number in the form (SCR #####).
VideoCreator now supports the 1024x768 display resolution.
(SCR 64941).
VideoCreator version 1.5 software could falsely report the
presence of a VME VideoCreator.

5. Known_Problems_and_Workarounds
Due to an incompatibility between the system PROM in certain
Personal IRIS systems and the SCSI-configured VideoCreator,
the following message may appear on power-up:
sc0: Unexpected transfer phase. State 4a Phase=10
scsi(0,4,0) transfer aborted (Hardware error)
Diagnostic failed
This message should be ignored. Press any key to
acknowledge the message and continue the startup.
Root permission is required to access VME versions of the
VideoCreator in Challenge and Onyx systems. The standard
commands and demos achieve this by running in "setuid root"
mode. If you compile your own programs that access the
VideoCreator in one of these system, you must either run
them as root, or configure them for setuid mode. The
following sequence of commands will modify the program
"myprog" to run with root permissions:
su root
chown root myprog
chgrp sys myprog
chmod 4755 myprog
exit

6. Documentation_Errors
Document version 1.0 of the VideoCreator Programmer's Guide
had an incorrect description of the genlock capabilities of
VideoCreator. The manual incorrectly states that the
genlock circuit requires RS-170A or CCIR color black, 1V P-P
into 75 ohms; the circuit actually accepts NTSC or PAL
composite video, 1V P-P into 75 ohms. A manual errata sheet
has been issued (document number 007-1368-010).
