Looking for the equivalent of the Colour Wheels in the Grading panel

stbo wrote on 3/14/2025, 5:00 AM

I am working with some SLog3 footage that I have been colour grading. Applying a LUT and working with the colour wheels make the footage look really good. The footage is a community theater show and uses LED lights a lot. In a couple of places the Blue and Green in particular blow out with the LUT and grading applied and I want to drop the Offset and Gamma briefly in several places in the video. As it is not possible to animate the colour grading I may have to go back and use the traditional key-frameable effects or splitting and cross-fading.

I wanted to confirm my understanding that the equivalent to the colour wheel in the grading panel is the Color Corrector and that the RL Color Wheels is the same as the Secondary Color Corrector - it seems to be when I try it, but I am also unsure if the Grading is doing anything else behind the scenes when using the wheels. it seems all the controls in the grading panel are also available in the Color Corrector effect.

I have read suggestions about splitting events and using cross fades, and I am also experimenting with that, but I am also looking at using keyframes but I would be interested in any observations from people who have tried one way or the other.

Thank you.

For straightforward A to B color grade change using the Color Grade Panel (e.g. individual grading for before and after tilting the camera), splitting and crossfading the video event works well enough. But if grading is more complicated requiring multiple keyframing, I'll use NewBlueFX's excellent ColorFast 2. A similar result can usually be achieved using both Vegas Pro's Color Corrector and Color Corrector (Secondary), but NBFX's CF2 does it more easily and with just the one plugin.

Whether or not the color grading engine used by the CGP is the same as that used by the Color Correctors is well and truly beyond my pay scale.

You could try adding the color grading panel to an adjustment event and then using envelopes to drop its opacity/intensity.

I don't think the CGP and old color correctors work exactly the same way but you can get the same result.

Try using the media generator with a grayscale and you can see how the CGP color correctors differ from the RL wheels vs the old color correctors.
