It's a node based compositing software used in production made by The Foundry. Basically After-effects but with more control using nodes instead of layers. [ame=" https://www.youtube.com/watch?v=ivREd2xX3qo"]Nuke breakdowns - YouTube[/ame]
^^ Agreed I got pretty close with duplicating the layer applying a highpass filter doing an auto contrast and setting the blend mode to overlay, it's kinda like doing a sharpen. You have to tweak the highpass settings to get what you want.
