White Balance Filter

[mattmatt]

Hi guys,

There are some features that white balance contains, that I have never used, and or do not understand. Can anyone explane to me the following tags? (refer to pic)

What does Cr and Cb stand for?

When would I want to limit the Luminance, etc? How would that help me? What is a practical example?

etc...

Thanks :)

This is in the help, though you need to read the section all the way through and not just skim the table...

A) Auto tries to automatically judge the appropriate white, gray or black value depending on what you select. It generally works best when the color isn't too far off.

B) Choosing Color Range here and clicking a color will set the Hue, Saturation and Luminance Limiter values to match the selected color. Hold Shift and click more colors to increase the range.

C) The Hue, Saturation and Luminance Limiters let you apply the White Balance correction only to a color or range of colors. This is what is often termed as Secondary Color Correction, where the correction is not global, but targeted to fix individual problems.

D & E) Cr and Cb are the Red and Blue color-difference values. The digital representation of YPbPr is YCbCr.

There's also this:

and another video I put together showing how to use both White Balance and Secondary Color Correction in Edius:

To more finely tune my White Balance results not only can I move the point in the circles (like a joystick), but the circles themselves also rotate to color-shift my adjustments.

Crazy!

Yes, thanks Thoff - great tutorial :) I downloaded it and whilst watching it, the part that I was getting excited about (colour range) cutt off half way through.....!!

I just downloaded the video here at work and had no problem. Try "Save As" and then view it.

[mattmatt]

cool, I try again - must have stopped it before it finished.

Thanks THoff,

I've been looking for a tutorial like this one for the past year. Thanks to you, now I understand the white balance and color correction filters.

Edius has many wonderful filters, but hard to figure out. Video tutorials realy help us to understand quickly. I know that Edius has a training site, but it hardly scratches the surface. I wish more experts such as yourself would post more of these video tutorials. They realy are helpful to amateurs such as myself.

Thanks again THoff.
