#PAR Brightness control

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. -James Franssen

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.

>> 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. << 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. -James Franssen

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.

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 Franssen

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
