Mapping Pixels (White Balance?)
by Derek Pankaew on Mar 15, 2006 at 9:05:03 am

Hey Guys,

Is there any way to White Balance in Vegas, even manually? I'm a Photoshop/After Effects kinda guy, and the color corrector makes absolutely zero sense to me. I'm trying to correct a very bad raw footage with Curves alone.

Is there any way I can say to take a value (say 168 on the blue channel) and map it to another value? (Say 245.) I did a search and I know there's no auto-white balance, but is there any way I can manually map the pixels to white? Curves doesn't have the Input/Output options, and the Levels interface makes no sense to me either.

Also, is there any way to see a pixel's values in Vegas? Right now I'm taking snapshops and pasting them into photoshop to use the eyedropper tool.

Thanks guys!

- Derek

Use the color corrector. A quick and dirty way:

Click on the "high" complimentary color eyedropper and choose something that should be white.

Click on the "low" complimentary color eyedropper and choose something that should be black.

Click on the "mid" complimentary color eyedropper and choose something that should be grayish.

Now fine-tune as needed.

Is there a way to color match two shots of the same scene from different cameras. One camera was white balanced correctly, the other was not.

Use the Split Screen tool. You can copy a frame from the "good" camera to the clipboard and the split between the clipboard and the "bad" camera. It's the button that a circle that's half dark and half light just above the preview screen. There's a drop-down arrow to pick the desired mode.

Thanks,I can see both clips and can switch between them. Now, how do I transfer the correct color to the bad clip. Is there a tutorial anywhere that explains this. I did a search on the internet but didn't find anything.

[Daniel Thornton] "Now, how do I transfer the correct color to the bad clip."

Not sure I'm following this. You would be adjusting the bad clip to begin with.

Thanks again for the help. I miss understood how to color correct a clip. I thought that you could read the color values from the good clip and type these values in the bad clip to adjust the clip. I understand now that you use the color correcting tools in vegas to match one clip to the other by eye, adjusting the sliders until they match.
