Cleaning up dark footage in Vegas

dholt wrote on 11/3/2003, 2:53 PM

I taped a wedding with two cameras this weekend and the Sony TRV950 had some problems with the church lighting. The pictures are really dark. When I lighten them up in Vegas I get a grainy effect? Is there any way to lighten up this footage and still make it look clear using Vegas tools? Thanks

IIf you are using the Brightness/contrast, you'll get the grain. Try HSL for starters, then look at using a blend of the video doubled, then adding the convolution filter to the top track to create false detail, running at about half or less opacity. There are other tools to be used, but this is a good start point.

My favorite tool for brightness and contrast adjustments is Color Curves.

If REALLY dark, you may have some success getting rid of the noise running it through the various filters in VirtualDub (free) as a prestep.
Then do as DSE and Gary suggest.

try glow or secondary color corrector and boost the gamma

Gamma is a great tool for changing the lighting without adding grain. Start with the standard color correction tool as described in BillyBoy's tutorial and adjust the gamma after using the eyedroppers.

Duplicate video track to 2nd track.
Change the 1st track composite mode to ADD.
Adjust the 1st track opacity till you get the brightness you want.
