You get 6-in-1... I think of this as more of an efx tool. For example, working with a client's logo, color match in the video wasn't quite right. Easy to dial in multiple colors with Aav6cc.

So, yes, 6 secondary color correctors for those occasions that call for manipulation of multiple colors but not color balance. IMHO it's no better than the sony cc tools, just a different interface to perhaps "color-map" rather than "color-correct".

Ah! Yes Seth excellent example right there!

Yes! Got it now.

Sure. Having Colour Mapping is one BIG advance over 2nd Colour Corrector. It's a "Six-Pack" - as we say "Carry-oout!" (it's a beer thing!)

On this basis I can see much I can do then. I still want to see a double click on the slider for "reset" to ZERO?

Tell me, just what do the negative numbers actual represent? An absence of GREEN or a REMOVAL of GREEN? Or what?

TIA

Grazie

Well, I'm quite hesitant to represent myself as an expert in this particular are of video color theory & engineering, but as I understand it:

The numbers refer to the degrees we see on the color wheel represented in the vectorscope. So, a negative number would mean moving counter-clockwise from a starting position on the wheel (eg. for a starting position, red maps about 105 degrees), a positive denotes clockwise movement from that starting position.

Aav6cc gives us -180 to 0 to +180. That will give us the full 360 degrees of the circle. So, if we grab the red adjustments, a negative hue will first pull red and remap it towards yellow, if we keep on going, on towards green. -180 on the Red channel is the same as +180 = Cyan.

For some real fun, drop the "gradient" test pattern on the timeline and apply the 6cc while viewing both video preview and the vectorscope. It tells the story much better than I can with words.

OK .. ? So why does the slider, far right, finish at 179? But I do take your point!

Actually Seth, I was referring to the BnW Slider, which has a range from
-200 < 0 > +300 . That was my observation. Why this range?

Ah! I did this with the PAL Test Chart. I could see the RED being zapped to white.

Does it? It looks pretty and very '60s? But illuminating? Oh dear, I think I need help . . . .

Now I really do feel that a Help.PDF is in order here.
