What other Nuke tutorials do you want to see? 🤔
I think something to do with lens flares would be cool. The correct way to use them, the different types of flare etc
I'd love to see one on color matching plates
some set extentions will be nice
A full compositing shoot would be nice..could be a simple one..but to show us the right steps to accomplish the final shoot specially prespective of elements in one shoot..and some of gizmos you usually use to make it fairly easier..so simple composite scene could be nice
About Gizmos and where we could find them, the best ones
Thank you so much for this series! One of the few truly concise introductions to Nuke.
No problem! I had loads of requests for a keying video so I figured I better make one 😅
One of the best Nuke tutorials I have seen. Thank you so much for your hard work!
Thank you! Glad you like it
It’s great when you find someone who knows more than you and teaches in a way that you resonate with. I’m excited to get this project file and follow along. Thank you for making it.
Glad you liked it! Thank you :)
This was enough for me to switch over to nuke. This thing gives you complete control!. Great tut. I have all the info I need from this tut!
Glad it was useful 👍
Nice and clean tutorial! Great channel!
Thanks!
I would love to see more about set extensions as well. I love your content!
Noter! Thank you :)
I don't use Nuke and this was so useful! A masterclass in keying. Thanks man!
Haha! Thanks dude. It's all fairly universal. Different softwares just have the buttons in different places 😉 the approach is always basically the same
Top stuff! Cheers :)
Thanks Josh!
Great video!
I would love to see a follow up on how to get good hair details while keying.
Thanks but did you miss the part of the video where I talked about keying hair for 4 minutes at 11:20? 😅 What else do you want to see that I didn't cover here???
Thx for the great work 💚 please Keep doing nuke videos 💚
Thanks! Will do 👍
thanks for sharing these great tips, was just thinking wouldnt the edge extension trick also eliminate the need to do the edge painting if you extend the edges far enough? Also do you have any tips for blending edge and core mattes such that the transition is smooth between the two mattes?
Thanks, glad you liked them. If you push the edge extension so far it covers all the motion blur it would be way too strong on the rest of the subject. So you'd have to basically keymix one with and one without and then paint in the mask to reveal it which is essentially the same process as what I did anyway.
As for blending them, the core matte shouldn't really need blending in. Both alphas should have a value of one and you should erode it to the point where it doesn't go over the edge anywhere. You could try blurring it or using an erode with a mask so it only erodes soke areas for more control. But generally they should go together pretty easily
Thanks man
No problem!
Hello @Alfie Excellent video. why did you stop with just one video. please continue the keying series.
Thanks! I'm slowly adding to this series over time
Is it just one video or are there any other about keying, anyhow would love to see your videos regularly
This is the only one on keying so far. The series is about learning Nuke in general
That edge painting tip is so useful. Thank you so much for sharing your knowledge and experience! Quick question for you, from your experience, what's your opinion on green tracking markers on a green screen? I heard recently that that's the way to go, and after dealing with some footage with a green screen with yellow tracking markers, I'm definitely sick of the way that that combination screws with hair. Any strong opinions either way?
Thanks! Yeah it's a super handy tip.
As for the markers, I think it depends on the shot. I mostly see red markers on screens just due to contrast. I think if the camera isn't moving much then green markers are probably quite helpful as they're less of a nightmare when passing behind hair etc. But if the camera moves fast or there's camera shake, green markers will get lost in motion blur very quickly. So it depends!
@@AlfieVaughan I didn't even consider motion blur. That's great to know, thank you so much!
Pretty useful and a great video! Got a question about the Gizmo. Where can I find "ColourEdge", does this one belong to a Gizmo pack or something? I couldn't find it... Cheers!
I believe it's from nukepedia although if you can't find it maybe it's been deleted. There are plenty of others like colorSmear etc or even the default one in nuke called edge extend.
@@AlfieVaughan Thanks for your response. I will check them all.
I like your videos, great stuff🙌
I fully support the Noob series 😂
Hahaha 😂 Thanks Kyle!
Do you use ColorSmear gizmo or any similar?
I've used colorSmear before. They all do the same thing really. I prefer the controls in ColourEdge but it's all personal preference
Once u do the edge extend how do u finish the hair part? It is still in grey isnt it?
Thank u
Edge extensions don't really work on hair as it's so fine. I usually just put a constant that's the colour of the hair though the alpha and blend it in
Best class
Thanks!
is anyone else having an issue were the sliders on the keyer node has no effect on the image on viewer1 (all nodes are connected)
Are you looking at the alpha channel? It doesn't do anything to the RGB channel
@@AlfieVaughan Ty bro, i forgot to switch Lum to Alpha on viewer1. lol
How did you get that style of backdrop?
In the node tab you can change it from fill to border
@@AlfieVaughan cool thanks
Can you please provide footage link
It's on my Patreon. The link is in the video description
Hey,
I might be dumb but I can't really find colouredge gizmo on the web :/ Any chance you can give me a dropbox link or something to get it? Thanks in advance!
Ah weird! Maybe it's been removed. Nuke has a built in one called EdgeExtend that does the same thing :)
@@AlfieVaughan Thanks! :)
is nuke fast or do you have to render prores proxies for everything
That's more of an editing thing than a compositing thing. I'd also say it's more about your PC specs than how fast Nuke is. I work on EXR sequences not prores
@@AlfieVaughan I've just barely dipped into your videos and I'm learning a lot! and I've been doing video / compositing for 15 years! I've never tried ACES going to try it today
Glad they're helpful! ACES is great. I use it for everything at home and we've been using it at both VFX studios I've worked at for the last few years
Please can we use nuke non-commercial to learn
Yep you can
Great
Thanks!
@@AlfieVaughan MOST WELCOME ALWAYS ..PLEASE ALSO HOW TO ALEMBIC FILES .ABC FILES ..ALONG WITH CG MESH MODEL WITH TREXTURE AND CAMERA EXPORT TO MAYA TO NUKE TUTORIALS PLEASE
Finally XD
Haha 😁 hope it was worth the wait!
@Alfie Vaughan ye indeed.. one if not the only fast smooth into the point tutorial I ever saw ..decent explanation..you should really be tutor soon😉 ..epic as usual bro keep going
Please make the same blender for noobs..
I don't do any keying in Blender I'm afraid !
@@AlfieVaughan Same series for Blender
@@AlfieVaughan not like keying but modelling texturing animation in blender for noob
Hey alfie please make a video on the roadmap for becoming a director, i am struggling because i don't know how will i earn from this ...
I'm not a director I'm afraid so I wouldn't know!
Is there reason why you would stack the IBKcolour nodes rather than just increasing the size?
Not really as far as I'm aware. Just a different way to get the same result. I'm sure when I was learning I saw a tutorial of someone stacking them so I've always just done that
@AlfieVaughan Ah ok, thanks! Just another question, and I think you sort of answered someone else but I didn't quite understand; how would you clean up the grey around the hair and glasses after using colouredge/edgeextend? And how would keep or add the reflective quality of the glasses? Thanks again!
@suzelise the hair can be tricky. It would probably be a case of eroding it slightly and merging a hair coloured constant into the plate using the alpha so it maintains the hair outline of the key. Then you can mix that in on the edges to remove the grey edge.
For the glasses, I'd probably roto the bit that couldn't be keyed and just despill it so the green highlights became white
