#Sanyo GVRS-950
5 messages in this thread
I know a bunch of you use the Sanyo GVRS-950, so I have a question. I
noticed some stuff about the device on another thread, but I am
wondering about output to the device through Visual Basic.
3D Studio doesn't do a real great job of controlling the unit. When
it works, it really works great, but doing Disk-To-VTR is more of a
pain that anything else (and Disk-To-VTR is where I start making
money, if you know what I mean!). What I am wondering is if there is
a utility that will allow me to do frame-by-frame control of the unit
through Visual Basic (or whatever, but VB would be nice and
customizable).
Anyone heard of this?

I haven't had any trouble controlling the unit with 3DS, but it would
be easy to do it with any other program. To control the deck, you
simply send it commands over the COM port, just like a modem. For
instance, "REWD" sent in ASCII over the com port will cause the deck
to rewind. All the commands are there in the user's guide.
I have done a lot of batch mode xfer to tape, using a little program I
wrote to create a script that uses the "SAN" program to send single
commands to the deck. I do this to put multiple animation sequences
to multiple places on the tape overnight.
I figured I could make it work with a little programming, but come on! I'm
lazy.
What is you batch file sending to tape? Targas? Do tell…

Here is an example of my program's output when I wanted to grab lots
of segments of frames from different parts of a videotape. TGRAB5P's
parameters set the input to SVHS and specify an exact frame (as in
f2910) and the output filename prefix (in this case, TEMP). After
each frame was grabbed with the TGRAB5P utility from my BBS, I
converted it to a much tighter, single field version and deleted the
original. Alchemy was used for image conversion to compressed TIFF
with a resolution of 315×243 (this deletes the odd field and sets the
correct aspect ratio for 1:1).
tgrab5p /S f2910 temp
alchemy -X315 -Y243 -t1 temp0001.tga
del temp0001.tga
rename temp0001.tga bmov0001.tif
tgrab5p /S f2911 temp
alchemy -X315 -Y243 -t1 temp0001.tga
del temp0001.tga
rename temp0001.tga bmov0002.tif
tgrab5p /S f2912 temp
alchemy -X315 -Y243 -t1 temp0001.tga
del temp0001.tga
rename temp0001.tga bmov0003.tif
etc….
And here's an example of the batch file created by my program when I was laying
frames to tape. I use the excellent TTOOLS TTSHOW utility to put frames from
the disk to the T+ card. The SAN commands specify edit in and edit out frames.
ttshow finl0001.tga
san edin 6300; edot 6301; edit
ttshow finl0002.tga
san edin 6301; edot 6302; edit
ttshow finl0003.tga
san edin 6302; edot 6303; edit
ttshow finl0004.tga
san edin 6303; edot 6304; edit
Pretty simple, eh?

I have a program that controls my Sanyo from VB for 3DS animation, but the bad
news is that it only works with the Fast Video board. That's because I load
each frame for animation using the calls for the Fast board. I haven't been
able to find something similar for my Targa+ board, although I'm told there is
a Windows program somewhere that will at least control frame grabs.
If there is such a Windows program, then controlling it with VB is a
piece of cake, as my program (which also contains VCR like controls
for the Sanyo) can just make a call to the other Windows program
which will load the frames into the Targa+. If there isn't, or you
have some other video board, you're out of luck.
