  • Colour Curves plugins for Vegas pro 12? (for separate colours/channels)

    Posted by Blake Gibson on November 22, 2014 at 1:30 pm

    Hi guys,

    I’m wondering if there are any colour curves plugins for vegas that have each channel/colour as a separate box to adjust in (like in premiere/avid etc/after effects)?

    I find the way that vegas uses one box and bunches them all together strange and difficult to deal with. For Instance: after adjusting the RGB (luma) curve for exposure etc, and going on to different colours/channels, it remembers the position. Also I can’t seem to figure out how to get back to the RGB/luma only curve after adjusting the other colours/channels.

    I prefer to have everything in separate boxes so I can tweak perfectly and know it’s not changing going between them

    I’ve tried Magic Bullet Looks, and even though it’s got separate boxes, you can only use the preset points on the curve and can’t go to the very bottom.

    Hopefully there’s something free out there, but at the moment I can’t seem to find anything at all, paid or free!

    Thanks for the help!

    Sony Colour Curves allows me to select each colour.

    Like Graham said…

    It’s built-in.

    It not only allows you to select each channel, it allows you to copy the settings for one channel to the other two channels. Then, you can make additional changes to the curve for each color. I frequently use this ability to adjust colors like yellow which utilize two of the three color channels set to the same values. It is a very powerful capability built into Vegas.

    Thanks for the replies guys.

    Hmmm… I really don’t like having the colours start at the same point I set my RGB curve to, I prefer it to start neutral, dead in the middle. I find that when I make a point on the curve is auto adjusts slightly from the RGB point.

    Also:

    Say I make an S curve to make the image more contrasty, then go to red, play with that, green and blue and play with them and I decide I want less, or more contrast so I go back to RGB to tweak the my S curve (contrast), it has all the colour channels in one box and I can’t select the RGB one… it’s gone. When I click on the curves it goes onto one of the colours, if I move the curves sometimes the whole curve moves, not just the point I select, it frustrates me.

    Also, I can’t drag the very top of the curve (highlights) across the top horizontally, only vertically. Likewise with shadows, no vertical, just horizontal.

    Do any plugins exist that anyone is aware of that separate the curves in different boxes?

    John Rofrano, in your screenshot example, how do you get back to the RGB/Luma curve to adjust contrast?

    [Blake Gibson] “John Rofrano, in your screenshot example, how do you get back to the RGB/Luma curve to adjust contrast?”

    All of them adjust the contrast. You can adjust them all together, or each one individually. The RGB settings controls all three color contrasts together. If you select Red and adjust that separately, then the RGB setting controls Green and Blue together. If you then select Green and adjust that separately, then the RGB setting controls nothing because Blue is now also independent. Once you have separated them all out there is no logical way to adjust them together because they all have different curves. The curves can have any number of independent control points. How could you possibly control all 3 after that? Which control point would you use?

    My suggestion is that you adjust them all together to get the overall contrast you want and then tweak the individual colors after that. Like I said, once you are separated them out into 3 curves there is no way to adjust them together because that wouldn’t make any sense (i.e., they are different and don’t have the same control points)

    Well, having just gave it some “Grazie-Thunk“, I added ANOTHER CCurve instance to the chain and with that one I can adjust the pre-adjusted, separate Curves all at once. Would that help?

    John, what I meant was, when I first add a color curves and adjust it does luma only with no colours, that’s fine, I can add more contrast, less, whatever. Cool. Then, I go to the other colours and tweak them a bit, from the top down I go: red and adjust that. Then green, oops, the green curve started in the same spot as I left red, not the default straight line. Same with Green and blue….

    And if I want to adjust contrast only again without colours, I have to add another instance of curves? I can’t get it back…?

    I’m not going to lie, that is confusing and convoluted in my eyes. Granted, I’m still learning and don’t understand curves fully, but I haven’t seen any other NLE’s or programs that have the one box for everything. Avid, Premiere, AE, resolve, all have them separately. Which is why I’m hoping there’s a plugin that has the separate boxes as I have a project due tonight/tomorrow and I need to make adjustments and I don’t have time to try for the learning curve (hehe) of the sony curves.

    Graham, how much would adding another curve have an affect on quality at all? I won’t matter so much for me for this project because I’m using Prores HQ… but other projects that are less robust, like h264 from DSLR’s can’t stand up as well and fall apart really easily

    [Blake Gibson] “And if I want to adjust contrast only again without colours, I have to add another instance of curves? I can’t get it back…?”

    You don’t understand what Color Curves is doing. There is no luma control without color! There is a luma control for each color. The default is to control all of the colors at once. Red + Blue + Green = White. So when you adjust them all together you are adjusting what appears to be the white luma but it’s really the luma of all the colors combined. Once you decide to adjust one of the colors differently, you have to way of adjusting them all together anymore because you made them different. i.e., the “White Luma Adjustment” no longer exists because it only exists when all three colors use the same curve.

    You can certainly add two instances and leave one for overall adjustment of all three colors together and another for separating out the colors. You can also use the Levels plug-in and Color Corrector plug-in. There are lots of ways to changing the luma and color of a video.
