Divide Blend Mode for VEGAS Pro

alifftudm95 wrote on 3/28/2020, 10:47 AM

I learn something amazing today about the math behind "Divide Blending" mode from and how it can be used to remove color cast on the video. (Maybe this can fix VEGAS Pro sluggish inaccurate WB tools)

This should be universal across entire editing software, as devide blending only devided the RGB value of the color

underneath the "devide" layer.

The way this method work is to create a solid color and pick a color from the images/videos that have a cast on it. (Color that supposed to be white but arent), then simply blend the solid layer with devide blending mode.

256 " 8 bit color " ( A ÷ B )

= R G B Value

This straight away remove color cast on the images/videos & make what supposed to be white, to be an actual white (WB corrected I shall say?). Sadly, VEGAS Pro don't have any divide blending mode and this should be add on future VEGAS Pro 18.

Luckily, I own a VEGAS POST product and I remembered VEGAS Effects have bunches of blending mode option to choose from. It does works, but sadly I dont have the ability to tweak Brightness to regain back the highlight detail as in videos. I tried to use Fill color FX in VE but the FX is very simple and it doesnt offer any small tweak control for hue, saturation & brightness.

This small control (Hue/brightness/Saturation) can be founded on After Effects (Both Solid layer & Fill FX) & in Premiere Pro too.

Afaik there is no native plug-in in Vegas itself, but take a look at graide color curves, there you will find this possibility to edit brightness, saturation and hue.

Thanks to SeMW since many years I don't use other grading tools within Vegas software. Before that and still there is the levels FX that does a litle of wat SeMW can do.

No that's a task for the developpers, most of your suggested things I don't use because I'm satisfied with what I can do with the program.

Why can't you use hsl adjustments present in the vegas color grading panel after doing the divide blend in VE?

Well idk what kind of editing you're doing but I've been getting involved with a bigger projects and most of the time I found myself stuck and can't able to execute simple visuals with VEGAS Pro. The WB tools for an example that are supposed to fix WB aren't really fixing any WB, so an alternative way is to use this simple trick devide blend mode. But if VEGAS cant even give that an option as a professional editing software, seems like VEGAS is far left behind. Not to mention the ability to blend the clip instead of blending the layer only. You can see this features in Pr and other NLE too.

 

I don't think this is a request. Its a features that must have for a "professional" editing software. vegas pro miss that point alot.

Another Plugins, another money. VEGAS Pro should have all of this ability as standards. Premiere Pro have way more features & FX and you don't even need Plugins to do it.

I do this seperately in VP & VE. VP don't have any devide blend mode, so I launch VE and import the same clip and give it a try. It works. It does remove color cast. But as stated in Pixim Perfect video, Divide blend mode will reduce the highlight detail, so you can fix that by bringing down the brightness. I don't even have a control for Saturation, Brightness & Hue in VE Fill color FX.

 

So in conclusion, It does remove cast, but in will remove detail as well. Its not the same if you add Brightness Contrast FX after on, it wont bring back any detail.
