VFX artist and educator Paul DeNigris walks you through more advanced keying techniques - managing alpha and RGB separately, using IBK, and using Keylight as a spill suppressor. Footage not available for download, sorry!

Hey Paul, great tutorial! I have a vaguely related question: as a compositor, what color markers do you prefer? Different shade of green, orange or something else? Thanks for the tutorials!
@PDeNigris6 жыл бұрын
I tend to prefer yellow markers because when you look at them in the green channel they pretty much disappear, and when you look at them in the red channel there's lots of contrast for tracking.

Please advise me: I have made a 3dmodel in 3dmax with both textures and lights. I will transfer it to Nuke via Alembic and here I want to assign to this 3d geometry the same textures that the model had in 3dmax. Take a video - thank you

Hey Paul as i have just started to learn Nuke i needed a help with this tutorial as i click on view IBK Colour Node it says a error Missing input channel tried looking online for the same as there is nothing availble for the same error if you could let me know how to fix it it would be helpful Thank you
@PDeNigris6 жыл бұрын
Milan, you have to make sure that your footage is feeding into the IBK_Colour node, and you've set the node to either Blue or Green depending on the color of your screen. And then the IBK_Colour node feeds into the C pipe on the IBK_Gizmo, while the footage feeds into the BG pipe. If you tweet me a screencap of your script (@pdenigris) I can troubleshoot further!

Alpha pipe and colour pipe, always have your alpha separate for best results. Denoise is not the best tool in Nuke for noise removal, it often softens and loses a lot of fine detail. Its best to use a plugin like Neat Video which we use at Dneg. Remember to bring back that luminance lost when despilling too!
@PDeNigris6 жыл бұрын
Agreed, Neat Video is great. For tutorials I try not to include to many plugins and such that are outside the base package because that limits the tutorial's usefulness for people who don't have access to the plugins. And lost luminance wasn't a factor here because of the dark BG. I thought I mentioned that in the tutorial but maybe I missed it.
@rob4eva6 жыл бұрын
I might of missed that myself, yeah I appreciate others might not own the plugin, let alone own a legit copy of nuke. I tend to bring back luminance no matter what though in my comps, we always try to match the plate in a none destructive way, keeps the supes happy plus at work we get other artists to tech check shots all the time and they're pretty anal about stuff when it comes to changes in detail, lost detail etc.
@PDeNigris6 жыл бұрын
Right on. I appreciate the constructive dialogue, and I love hearing how other studios do things.

@@rob4eva How would you bring back the luminance after the despilling? Or just a good starting point to look up a reference, if its too much to comment on? Appreciate it! Trying to up my Nuke game.
@rob4eva5 жыл бұрын
@@BrianDyak after despil, merge (from) the plate which should give you just the green. , desaturate the green to black and white using expression node with max(r,g,b) in the r, g and b, using saturation node set to 0 also works but i prefer using expression, the math does it more accurately.. then plus that back o to the despilled image. Your basically converting the green despill into black and white then plusing it back onto the plate. The green is still removed but you have put the luminance from the green back onto the plate. Then nothing is lost except the colour. As for those edges.. try multipling your background onto the desaturated green.

Nuke seems like its one of the most expensive VFX tools out there huh? Don't get me wrong, I want want VFX artists & graphics programmers to make as MUCH money as humanly possible because God knows how much hard work goes into all of this stuff but I'm just curious because as I understand it, Nuke is for motion tracking & compositing correct? It seems like such a cool software but been trying to figure out what it does exactly lol. I only do modeling, texturing & have learned some basic rigging & animation so i got interested in what the process is for mixing live action with CG. I know syntheyes is more in the affordable range but what else does Nuke do?
@PDeNigris6 жыл бұрын
Yes, Nuke is pretty expensive, you're correct there. And yes, other software can certainly do some of the same things that Nuke can. Adobe After Effects for example is good for someone just getting started with compositing. (I'm not familiar with Syntheyes.) Where Nuke excels is in speed. I can do the same tasks faster and better in Nuke than I can in AE. (I use both.) Faster in terms of rendering, but also faster in terms of workflow. Nuke's node-based architecture allows for faster working, easier sharing of nodes and techniques among artists, and easier duplicating results for numerous similar shots in a given project. For blending live action and CG renders, Nuke's handling of AOVs (aka Render Passes) is unparalleled.
@nvdsnt6 жыл бұрын
Syntheyes is "THE" most powerful tracking software. [period] but you can't composite with it. After effects is the cheaper option and honestly if you're afreelancer and not planning to composite for big studios, After Effects is enough. but there are some situations that after effects just leaves you with a very messy project file that no one can figure out what's going on.
