Brightness

[Fozzee]

Hi
I previously had a geforce 2 and have now bought a Geforce4 TI4200
I capture using an AverTV Studio Card. I get very good results with mpeg2 capturing.
The only thing is now the image viewed on my computer screen is now very bright with the new video card.
It's hard to explain but in bright scenes where sun or light is on peoples faces etc its too bright. Like a glare.
Which should i bring down?? Brightness or Contrast???
Or is this a different problem?
Also should i alter the video overlay settings on the video card or the settings within the capture program??

Hope you all know what I'm on about.

Try both, but also have a peek at your card's gamma settings

-Check in the Display settings for a gamma setting and adjust that to get the view you want. This will keep the video capture the same as before, but adjust the monitor for correct playback of the video.

"It's hard to explain but in bright scenes where sun or light is on peoples faces etc its too bright. Like a glare."
-That's oversaturation, in your capture settings start by bringing the contrast down a little. Then adjust the brightness to your liking. I would only do this if you are Not going to burn to CD/DVD or dub to VHS tape.
Always check the quality and video levels in your final playback device (ie DVD to TV or VHS to TV). Computer monitors often give you a different view of the video then on a TV set.

Fozzee,

Go to the link below for a more detail explaination of what to do. This page uses VirtualDub in the example but should apply to any capture software.

From what you have said so far is this correct????

If I alter the capture software settings (brightness contrast etc) I will be altering the picture forever.

If I alter the display properties for the video card I will only be altering what I see on my monitor??
I have done both and in scenes of high light or bright whites (snow etc) I still have problems . Overglare I call it.

I never had this problem with my Geforce2.

VERY surprised no one can help with these questions!!!

Anyway another one

I am still experiencing this GLARE on faces etc and objects in snow are indistinguishable.
I have lowered various settings . Gamma makes no difference in the capture window only to the desktop.
I am very miffed by this as my it worked gr8 with my Geforce2!!??

Does this movie has black bars at top and the bottom ?

Hi
This is not a particular movie.
It's capturing in general. The TV displays like this b4 i capture.
It gets slightly better after capture.

Look like your new cature card have higher sensitivity than before.
It is possible the card is faulty or trimmed incorredtly.
You may want to reduce it with an attenduator to confirm the problem.

Does it do the same things on Video in and RF in ?

Hi
I connect using scart adapter and composite lead.
I haven't tried co-ax with The new video card but it was shocking with the old video card.
I'll try it.

Fozzie, you are not alone...

I have the same card (Geforce 4 Ti 4200), mine's the Gainward 128MB model with the integrated everything. I get the same thing, where the signal appears to be oversaturated, and it's based on the amount of white in the scene (so it keeps changing).

Messing with the capture settings really doesn't help, since it seems to be more of a reaction to the actual brightness signal, than being too saturated all the time. Almost like macrovision, in reverse!

I wonder... is there any way to put something between the source machine (VCR or whatever) and the card, so it will balance out things? Keep the signal from having strong spikes, I mean?

I wonder if maybe a "video clarifier" box, like a Sima Copymaster, might do the trick?

Maybe I'll dust mine off from being in storage and see what happens...

I was under this impression too (about the contrast/brightness on a monitor vs. tv).

however, I'm doing some DV capture (firewire) off a sony TVR900 and it's bright on on capture (much more saturated then if I svideo out from the camera to the TV). However, if I just burn that (convert to mpeg2) and burn it as an SVCD - that same over saturation/brightness shows up on the TV.

I don't understand why this is.. especially doing a DV capture (well dv is more of a copy really) - unless when i out to the TV from the camera, the camera is doing some contrast/color correction.

Hi

My problem has been resolved.
I replaced the scart adapter I think it may have been faulty
