Equipment Needed:
Equipment Setup:
The equipment are connected as follows:
Video Cart(v-disc out) --> SGI VideoLab I/O Box(rgb in)
Video Cart(VHS OUT) --> Vid/IO Box(VIDEO OUT) --> VideoLab I/O Box(RGB IN)
Video Cart(S-VIDEO OUT) --> Vid/IO Box(S-VIDEO IN) --> VideoLab I/O Box(RGB IN)
Sony Hi-8 Camera(S-VIDEO OUT) --> Vid/IO Box(S-VIDEO IN) --> VideoLab I/O Box(RGB IN)
This is an odd one:
Turn-arounds are needed(i.e. male to male connectors.) All we seem to have are the T shaped connectors, but these will do the job.
The two types of connectors.
They can usually be found in Imager Light in one of the bottom drawers of the filing cabinet on the immediate right as you enter the lab.
There are three ways to connect this up:
CCD: Lucy: Red ---> Red Blue ---> Blue White ---> Green (if you choose to sync on green ingore the next line) White ---> Sync (set sync to C on interface for Lucy's grab software.)
CCD: Lucy: Red ---> Red Blue ---> Blue Green ---> GreenThe last connection is not terribly stright forward:
Video out (on the back of the camera) --> Vid/IO box(video in) and (sync out) --> VideoLab I/O Box(sync in)
JVC CCD(Composite out) --> Vid/IO Box(video in) --> VideoLab I/O Box(RGB in)
One thing to note is that NTSC is subject to lots of noise, and will not (in general) give very good quality frame grabs. In fact this camera is quite inferior to the Hi-8 cameras that the department has.
Why use method two which seems to be the most complex? Well, it gives the best quality (certainly better than method three) and will cause the least amount of grief of all three methods. (Trust me, I've wasted hours :-)
