Please help! Underexposed video I need to fix urgently.
Does Vegas have tools to repare an underexposed video? All I can think of is the brightness filter. Is this the only way?
Footage in a restaurant of people dancing and mingling at the bar, ambient light is dim. Now this is shot with a 50w light on the camera. Mainly half body shots and close ups and shot real close with people close up to the camera. If you can imagine what this would look like underexposed. The background would be pitch black and the subject exposed at around 50% instead of 100%
It almost looks like the blacks are crushed expecially in the background. You can’t see the background at all. I’d like to be able to see the background in the shots.
The cameraman had his zebra and viewfinder on his camera set wrong which is what caused this problem (So I’m told).
What tools (if any) should I use in Vegas to help fix this problem?

Go to Color Correction (Secondary) and increase the gain, you have increase the saturation a little as well. That’s the place to start.

The first tool I go to for this type of thing is Color Curves.

Thanks to you and Gary for the quick response.
Is there a ‘measurable’ method I can use in Vegas to make adjustements? Like a scope or something that will tell me where the gain/brightness etc is suppose to be set to?
I’m doing this by eye but would like a measure to compare my eye to. I set my monitor up to have brightness and contrast properly, a scope would be handy too, is there such a thing?

color curves works excellent but it does have a higher learning curve then say using the Sony Color Correction FX using either gain ( lifts blacks the least) , or gamma ( lifts mid range the most) , or offset ( lifts all area’s equal) ..
guessing is using a combination of gain & gamma – watch the waveform …if you have not used the gain, gamma, off set in color correction fx i would recommend that you take a little time and experiment using the smpte color bars ( add generated media – sony test patterns to video track). keep eye on waveform while moving slidrs – then see what happens to the bars as you use gamma ( notice how it lifts the midrange nore then blacks & highlights) , try off set – note how it lifts all bars equal , then try the gain and note how it has least affect on blacks and as you go up the scale ( brighter bars reading right to left) each is raised more then the one before it ( looking right to left)
when using the color curves – you can add points so you only affect blacks or mid range , or highlights or all …

Thanks everyone!.
The Gamma in secondary colour corrector is giving me the bets results so far. I see light at the end of the tunnel now 🙂
What’s the procedure for adjusting the brightness and contrast on my external PAL monitor? I guess this has to be set properly before I can do anything.
