Hello everyone,
I need a little help, Im AE user, but at the moment I have access to Foundy Nuke and Im working on a project.
I want to change colour of the shockwave footage from videocopilot, like he do with the color, vibrance plugin in after effects.
What are the best/easy way to do this in Nuke?Thank you for any help.
The color correct tool has all the basic colour controls including saturation and contrast. You can click on the colour wheel icon on at the side of any of the sliders to adjust the tint of any of the controls.
To recreate the color vibrance plug-in I would start but desaturating the image completely, then picking a new colour in the gain slider.
Remember that when you are using colour correction tools on an image with an alpha channel in Nuke you need to make sure you unpremultipy the image before you do the colour correction, and re-premultiply your image afterwards. There is an option for this inside most of the colour correction nodes, or you can do it manually with the unpremult and premult nodes.
If you don’t understand the principle of premultiplication you should do a quick Google. There are some good explanations. It is something that After Effects deals with for you behind the scenes, but Nuke does not. It’s a fundamental principle of compositing and once you understand it you can figure a lot of problems out for yourself.
Thank you raiders, that was a very useful answer.
premultiplication something completely new to me, I have been working with AE many years.Regards
