Nuke Tutorial - Fixing Edge Contamination with Colour Smear 

I literally painted out stuff like this for the last 4 hours to now find that tutorial which would have solved my problem in 1 hour -.- Anyway, great tutorial man!

Found your tutorials during my final exams. perfect. THANK YOU SO MUCH !!

Invaluable content ! Didn‘t kow about this gizmo , thank you so much !

It is really cool trick for fixing white edge. thank u so much for going so deep. Normally people do not go that much deep in tutorial. Again thank you so much from all of us who is working on nuke.

I do the same thing with different long technique. This one is useful and easy to play with. Thanks

Great tute thx heaps - when you are doing the frame by frame feathering at 11:42 you cld use the ripple button in the roto toolset and it wld apply the same feather to all the keyed points. Only thing is to make sure you turn it off when yr done (or it will cause a ton of trouble)

Awesome sir :)

Great tutorials sir Thank you so much 😊

great tutorial! perfect!

thank you paul.

Great tutorial. Thanks a lot

just finished some shots & this was a very similar approach about how I solve it, just a keyer with very high values can get away without rotoscoping, let's be clear that you need a floating-point image to bring back very dense detail edges like hair & stuff

Great tutorial, sir

Such a amazing tool thank you sir for the wonderful explain:)

amazon tutorial as always ! thank you!

Hello, I'm a beginner trying to composite a new background for my stop motion Tiff images that were created from a photo editor program (not photoshop). I created layers with parametric masks based on luminosity and key and luminosity combined but they are only RGB layers. I managed to send the red layer to the alpha channel in Nuke but in some cases the mask is slightly larger than the subject. Would I be able to use colour smear to shrink back the mask and add some motion blur? What other tool do you recommend if I want to refine existing mask layers? Or if the mask layer has some of the background bleeding through yet I want the whole area to be consistently masked?

hello when ever I premult the colour smear all the extended pixels disappear please help. What I mean is also is that the smear mask is too thin in relation to the actual rgb smear pixels so whenever I premult the colour smear is much smaller than I need it to be. How do you ensure that the output smear mask is exactly the same and extends as far as the colour smear?

Thank you sir ❤️

You could save it as a toolset inside Nuke, so you dont have to copy and paste all the time.

Quick question: when I merge the roto back with the plate, my key is completely exposed again (showing the green screen). How do I get it so that the roto shows without voiding the key?

very great tutorial , thank you so much too shearing your experience ..

Sir please make a tuts upon vector blur edge blur and blur I. Nuke

Super. Cool techniq

I'm new to Nuke and can't get Color Smear to show outside of my actor - I think perhaps I have the node in the wrong place? For reference, I'm following your other green screen tutorials and trying to get color smear to work after the fact. (The one where the guy is keyed on top of the scary looking house). What am I doing wrong? I see color smear is affecting things but it seems to be constrained to inside my actor, not outside.

Ohhhhhhhh! this is why I was using after effects for this kind of work! missing the refine hard matte and refine soft matte in nuke.

I can't see the download option

cool, I was just wondering what's the difference with the EdgeExtend tool? Thanks!

some people are saying that after this corona there Wii be so many jobs in vfx , so what's your opinion sir

Amazing thanks keep it up!

Hey sir, I’ve got 7300 VFX subscribers. Mind if I mention your RU-vid site as a resource via RU-vid?
