#PAR Brightness control
12 messages in this thread
I am having a problem with the brightness level of some flc's I've created
using Animator Pro. There have been some good suggestions, but no real quick
fixes (until I get a reply on how I fix .TGA's). Jim Beyer suggested something
that might work, if I can do it. Is there a way to adjust the brightness level
of an animation coming out of the PAR? This would be a fairly quick fix.
Thanks.

If you happen to have the TBC-IV you can feed the composite oy Y/C output from
the PAR back into the TBC-IV and the TBC IV's output can be adjusted with it's
procamp. Not sure if you can do this on the fly with software control as I use
the RC-2000 remote for the TBC and this is the easiest way. Otherwise you
could get an external procamp to mabe some brightness changes.

This is a bit over my head. I have the TBC-IV, and I see a button for the
TBC-IV on the PAR window, but this has the hue, luminance, chroma, etc. that
seems to only effect incoming video. how to I feed the composite output back
into the TBC-IV, and where can I find it's procamp (and what *is* a procamp. I
know if my spellcheck can't find it, it must not be that dumb of a question :)?
I looked in the manual and it mentions a CHR FILTER, but I already have this
on. Thanks for your reply.

OK, you do seem a bit lost.
The signal path is from your output of the PAR to the input of the TBC. This
will require rewiring it as you now have it for frame grabbing, but this is all
external at the back of the computer with video cables. Now take the output
from your TBC to your recorder's input. That's the wiring.
The "PROCAMP" is short for processor amplifier. This is a devive for adjusting
the luminance, setup, chroma saturation and Hue of the video signal. The
TBC-IV has this as part of its bag of goodies. Your only problem is how to get
at it while operating the PAR software.
How I do it: I do it the easy way. I bought a box called the RC-2000 TBC
remote control. This eliminates the need to control the TBC-IV via software.
I can just operate the PAR from the computer and adjust it's video levels with
the RC-2000.
For your setup I'm going to suggest a way to do it that should work but I have
not tried it here. Let me know how you do.
If you haven't already done so, load the TBC-IV software that comes with the
TBC-IV. Hook everything up as described in the TBC IV manual for operation of
a stand alone TBC IV. Feed the TBC a video signal from your VCR and observe
the video on a monitor hooked to the TBC IV output. Now we have the TBC IV
working. Next exit out of the TBC IV software and launch the PAR.exe. Load
the first frame or some frame of the animation to be corrected so that the PAR
displays the video on a monitor. Now exit the PAR.EXE. The frame will stay up
on the monitor. Launch the TBC IV software. Hook the TBC IV back into the
video line and make your adjustments as desired. Now here's the part I'm not
sure about but it should work. Exit the TBC-IV software and the settings
should remain. Re-launch the PAR.EXE and play the animation and record. I
think the TBC-IV will remnain as to the last settings so you will have your
brightness adjusted.
Of course the RC-2000 allows you to make these adjustments without going in and
out of the two softwares but then it costs $289. <G>
Hello Don
Who makes the RC-2000 and where can they be purchased?
Thank you
Ed
The RC-2000 is made by DPS to control up to 8 TBC's, their WFM/VS and the
router. One box for all. I know you can get it from stock at B&H.
Thanks
Ed
That seems like a lot of trouble. You can easily use procamp controls on a
PAR anim. First hook up your wiring the way you described, routing the PAR out
signal through the TBC-IV. Go into the PAR.exe and bring up a frame from the
desired anim. Next press the "TBC-IV" button located between the two file
windows. This will give you command of the procamp controls to adjust your
animation output without having to go into the TBC sofware. I have been doing
it this way ever since I got my TBC.
Mitch
You are absolutely correct, Mitch. I just hooked up and tried it. Works OK
even though you don't have all the control features of the RC2000 or the TBCIV
software, you do have what is necessary to adjust the basics. Since I seldom
need to do any adjustment of the PAR output I completely forgot that option
existed.
Thanks for simplifying things.

I have a call into DPS, but in the meantime..
Let me see I have this straight, I have a .flc that I have created in Animator
Pro. I've taken the .flc and used it as a background in 3D Studio and rendered
30 frames to the PAR. The animation that has gone to the PAR is too bright,
the Chroma level is too high. I am lost at the part where you suggest
rewiring, where I am to take the output from my TBC to the recorder. The PAR
ani will be seen on the recorder? I've tried Video Out from the TBC IV to the
recorder and all I get is a pink screen with a thousand little horizontal
lines. What am I doing wrong? Thanks.
-James Franssen
Don thanks. I've figured it out finally. Please disregard my last message
about the pink screen with lines.

James,
I did this several times, and i know the problems.
I have two videorecorders a Goldstar and a Mitshubishi, the Goldstar
has the possibility to adjust several things before sending them out
to the monitor, so i use the Goldstar to feed my Mitshubishi, and it worked
fine for me, and no timeconsuming rerendering to do.
Maybee this help.
Succes
Theo
