I like your way, you know what you doing, not like in Flame where they touch green and voila, " I have key !!" Thanks a lot for tutors. Very helpful. :)
When you discuss the matte edges for hair detail and the roto holdout mattes, the edges are aliased, not anti-aliased. Anti-aliasing is the blurring, or interpolating of jagged aliased edges. Otherwise, fantastic tutorial. I like how to you get to the point where others on the same topic give about 10 minutes of info in a 30 minute video. Well done!
Hi man thanks for sharing your techniques and tricks it has help a lot i just wanted to know how you deal with hard edges, black or white edges and how to colorcorrect edges for subtle output . Thannks for your efforts and hope you will get back on this soon...
These tuts have been so invaluable to me I can't even begin to thank you. I had just one question with the IBK technique. I never can see your settings for the Merge(Stencil)@25:06. I assume I need it to pass through the RGBA values all to the IBK but for some reason I can't make any of the following IBK systems that follow use the roto I created.
+TheBruceleeroy Besides being switched to stencil I believe his settings would be left to default. roto close to the outline of the hair, stencil it right after the first IBK colour, then the following IBK colours will patch inwards creating the clean screen without any hair artefacts. When you do the final IBK gizmo it will bring back the hair detail in the area that was stenciled. Hope that makes sense!
+TheBruceleeroy Daniel's right, I think the stencil was default. the big tip was adding the clamp to make the roto's edge aliased, or threshold, or just 1's and 0's. There is weird artefacts when you stencil with a transparent alpha.
How would you get rid of the noise that this technique creates in the black areas of your matte? I've just been dilating out my core matte and multiplying it back onto my merged edge+core matte, but that still leaves a bit of noise around my edges. Any advice?
Nice technique. With these good results, can I just ask on which kind of shots this technique usually doesn't work so well? I'm thinking of shots with a moving camera and / or loads of motion blur. Then again, this technique seems to be working fine on moving hair. Next to that, you mentioned IBK handles its cleaning on a frame basis so luminance changes within the shot will be compensated for. Still I'm wondering if you ever had to animate the color fine control on your blacks (in the initial ibk-color). Thanks again!
+The Nout I think generally these techniques should work for most keys. a lot of shots with tons of motion blur need to be treated as separate cases, and certain areas would need to be painted in or separately despilled, etc. its all shot for shot. Good question on animating the color fine control on the blacks. It could be useful, and totally reasonable if that works better. sometimes what I'll do it find 2 extreme frames (say if there is a lightning flash or fire flash for a few frames, and I will do 2 separate keys, then you can animated a dissolve between the 2 to blend the 2 alphas back and forth. That can be less of a pain in the ass as animating a bunch of settings, and gives you control on each key without worrying if you are accidentally screwing up the opposite key.
we can just use the InPaint node now, or any other blur & unpremult technique. 👍 it's just filling the hole, and I agree, it's a dated technique now, there are faster / better ways to generate a cleanplate
@@CompositingMentor I have just discovered your channel and find everything very useful even if they are outdated, I hope you find time to make new videos they are very helpful
@@Sher245 thanks a lot for the kind words, working on new videos on the side! Yes there is the InPaint node and also the EdgeExtend node, which was far as I can tell sort of do the same thing, one fills a hole, and the other extends the edges to the edge of screen. both available in nuke12+. very very fast
Thanks for this awesome tutorial. This whole series is by far some of the best learning out there.
Thanks for taking the time to create this, makes perfect sense. Only starting using IBK recently so it's shaved off a lot of trial and error.

Excellent! Thank you so much!
great class sir please give any hair roto session for nuke and silhouette sfx class that's much needed
Awesome technique! Thanks for this!
great technique! Thanks for sharing
hey tony, the dead guy footage in the last example, is that available for us to use? couldnt find it anywhere..

denoise node sometimes helps
Haluk Tarcan I always use IBK on a denoised version of the plate
Hey man.... I love you!

very true

great stuff, thanks for the tips!
awesome, thank you Tony:)
amazing
Shuffle value and color
That's not an anti-aliased rotoshape. It's aliased.
Good tut though.
While the IBK stack is a very useful technique its too time consuming, imagine having to do IBK stacks on 4k footages, it can get real slow .

how you dare to use green screen from blender, betrayal.
