Hi guys,
this is my problem.
I just purchased the genlock SuperGen. I hooked it up to an old
tape editing system. The problem I am having, is that when the
tape controller does any fast fowarding or pause, or any editing
stuff, it causes my amiga monitor screen to be distorted.
For example if I fastforward the source tape ( which goes into the
genlock ) my amiga screen (the whole screen) scrolls to the right.

This does not really cause a problem with the paint programs, but
when I try to use Pro Video Plus Gold, the screen goes black, genlock
LED goes Red and I have to re-boot.
Anyone please help.
COnfiguration:
Amiga 2000HD with 1MEG
Latest version of SuperGen and Pro Video Plus Gold
Two JVC 3/4" VTRs with a panasonic editor.

This is normal, all genlocks do that, at least the Amigen, the C=2300
and the Supergen, these are the ones I tried. When you put a genlock
on the Amiga, it syncs the Amiga TO the video source, since in FF or
REW this clock source is not stable, the screen breaks up. I don't
know what could cause Pro Video to lock up unless they use timing loops
that get screwed up when the clock is jittery. Pro Video is a nice
package, but since they use their own fonts, and don't have accentuated
characters, it is of little value to me since I can't display french
titles.

| 3900.2 | maybe a TBC is the answer | SALEM::LEIMBERGER | Thu Jul 05 1990 04:35 | 15 | |
re -1. You have that right. I have the same problem with my
SuperGen 2000s. I have noticed that if I have a video source coming
into the amiga,and am in DpaintIII my screen will become ghosted.If
I try to shut dpaintIII down I'll crash. However if I shut down
the video source I can exit ok. I just purchased Broadcast Titler,and
am getting to the point where I will be using it with the supergen.
BT has the ability to controll the supergen automatically according
to the effects you chose for screens. Another thing you will want
to be careful about is your video source. Make sure you black your
tapes before using them. Any unstable video source will break up
the amiga screen. I have been able to work around this problem most
of the time. I think the answer is to put a TBC in line between
the incoming video,and the amiga,but I don't have the funds available
at this time.

| 3900.3 | What is TBC? | TROA02::ITHOMSON | Thu Jul 05 1990 15:05 | 6 | |
Forgive my ignorance, but what is a TBC?
And what cost am I looking at?

TBC=Time Base Corrector. I haven't priced them yet but all I read
indicates $500+ . I haven't bothered to look into it because at
the present all my funds went for the supergen,and other video
equiptment. What happens is the input to the TBC is put out at a
very steady stable rate. TBC's can be analog,or digital. I imagine
all the latest will be digital. You may want to put a video switch
on your input line,and simply switch it when you Fast Forward. I
still haven't tried genlocking with Broadcast Titler.
