Solid color for lower Third CMYK, Pantone, RGB

I've created a solid and used event pan/crop to make a lower third. Client sent me over CMYK, Pantone and RGB values for "their colors"

Where do add these values in Sony Vegas Pro 13. RGB numbers would be huge....

Thanks!

Eh.... Putting my head above the parapet here. I'd import their colours and use the Eye Dropper to "match".

Now, let the fun begin!

Where can I find these settings in Sony Vegas PRo 13

[Thomas Roberts] "Where do add these values in Sony Vegas Pro 13. RGB numbers would be huge...."
You must convert your RGB numbers to the Open FX color values that Vegas Pro supports. OFX color values must be between 0.0 and 1.0. You can do this by using a percentage calculation. Let say that your clients numbers are R:255 G:136 B:0. You would divide each number by RGB 255 to convert to OFX values. So 255 / 255 = 1.0, and 136 / 255 = 0.53 and 0 / 255 is 0. That means you should put 1.0, 0.53, 0.0 into Vegas Pro to get your clients colors.

Graham surely got dinged in the helmet, for sticking his head above the parapet. But I would be interested to know if his solution with the eye dropper was close.

[Aaron Star] " But I would be interested to know if his solution with the eye dropper was close."
Here are my results.

Aaron, I sourced a Pantone <> RGB <> CMYK Sampler from the NET and selected their PMS105. It's one of those "nondescript", and therefore challenging, brown tones:

So, here are the original RGB numbers from that Pantone and the conversions for OFX colour values for Vegas:

R = 130: 130/255 = 0.5098039215686275

G = 117: 117/255 = 0.4588235294117647

B = 15: 15/255 = 0.0588235294117647


Have screen-grabbed their chart; imported to Vegas Pro13 and I apply my Colour Picker method, picking from my ExtMon as source, I get these values generated within GenMed Solid Colour:



You can observe the difference is that Vegas Pro has mathematically rounding-up using the 0.001 position

R: 0.5098039215686275 => 0.51

G: 0.4588235294117647 => 0.46

B: 0.0588235294117647 => 0.06


I'm guessing, and maybe John Rofrano could shed some light, that the "code" is making use of that part of the code to round-up the RGB OFX numbers.

Discuss.

Cheers

The eye dropper seems to work close enough for the girls I go with.

[Graham Bernard] "I'm guessing, and maybe John Rofrano could shed some light, that the "code" is making use of that part of the code to round-up the RGB OFX numbers."
Vegas Pro only uses two decimal places so if you have a number with more decimal places it will use standard rounding rules.

In my example, 136 / 255 = 0.53333333333333. When you round, any number 5 or higher rounds up while any number below 5 rounds down. For 0.533 the 0.003 is less than 0.005 so you round down and the 2 decimal value remains 0.53.

In each of your cases:
R: 0.5098039215686275 => 0.51

G: 0.4588235294117647 => 0.46

B: 0.0588235294117647 => 0.06
all of the 3rd decimal numbers were greater than 5 so:
0.509 the 9 is 5 or greater and becomes 0.51

0.458 the 8 is 5 or greater and becomes 0.46

0.058 the 8 is 5 or greater and becomes 0.06
These are just basic math rounding rules of adding +1 to the digit on the left if the digit on the right is 5 or greater. Vegas Pro does this for greater accuracy.

Thanks for confirming John that that is the way that Vegas rounds the second decimal place. Do you have any comment on the accuracy of my workflow and the consequent value it may give the user?

I would think that using the eye dropper on a Pantone swatch is just as accurate and way easier than doing the math (which some people might actually get wrong) ;-)

Good. Not that you'd be surprised but, the accuracy is from the ExtMon. Both the Timeline and Vegas INTERNAL Monitor get it wrong.

In that case, doing the math might be a more dependable solution.

Also I thought you might have said something about me screen grabbing the "swatch" and saving it, and here that was as a JPG. I was concerned about me introducing a "different" colour space - yeah? Hence my previous trepidation about my suggestion.

You can certainly get in trouble with JPG's because they do introduce artifacts. Thats why I like math. It's deadly accurate.
