0:40 what is despill?
3:40 Separating the Despill process from the Alpha process
7:33 Core Despill and Edge Despill
I’m going over the first section of Despilling. I talk about what despill is, why you need to remove it, how it should be separated from the alpha process, and combining core and edge despills.
The 2 main goals of despilling are:
1.) Removing any spill while still maintaining the original colors in the plate
2.) Blending the subjects edges with a BG colors
Here is the link to a great despill tutorial which goes over blending BG colors using the difference matte of a despilled plate –> to the original plate. If you are new to the concept of blending your despill with the background then you are really going to like this video. He talks about flame in the beginning of the video and switches to nuke later.
Thanks for watching, next I’ll go over how to achieve and control the despill to get what you need.
Sorry for not posting in a couple months, I have been traveling and working. But I am ready to finish off this series. I think you guys will like this one because I go over some techniques on the IBK workflow. The first part of the video I show you a comparison between how I usually see IBK being used and the IBK stacked technique. There are 4 examples (a greenscreen, a bluescreen, a hair problem, and a shadow problem) that I go over and explain the concept of what the IBK is doing, and the importance of the IBK Color, or cleanplate.
Next I give you a step by step breakdown of how to setup this IBK stacked techniques by building these 4 examples from scratch. If you are already familiar with IBK and want to jump into the step by step process of this stacked technique, you can just to 7:09 (Step by Step process, example 1 greenscreen).
0:45 Comparison 1 greenscreen example
3:54 Comparison 2 bluescreen example
4:31 Comparison 3 hair example
5:53 Comparison 4 shadows and markers example
7:09 Step by Step process, example 1 greenscreen
17:12 step by step example 2 bluescreen
22:15 step by step example 3 hair and assisted eroding
27:37 step by step example 4 shadows / cleanplate customization
At one point, my cursor disappears in the recording. Something must have gone wrong during the recording process, but you should still be able to see me clicking and marquee-ing stuff.
I’m glad to be moving onto the despill section, as I think it usually is overlooked. In reality it’s just as important as the alpha, if not MORE important.

8:37 Adding all channels
11:39 Adobe After Effects Matte technique
16:21 Channel math summary
20:02 Combining Mattes with Keymix
23:20 Isolated mask Post-Grading
In this video I break down the basics and fundamentals of what keying is and how you can make keys from individual channels. I also talk about using keymix to combine different keys, and how to isolate only certain areas of the key to adjust with a post- grade.
Here is the Channel Control tool I showed in my tutorial:
Here is the Adobe After Effects Matte Technique Gizmo:
My next video should wrap up the alpha section, stay tuned.
I’d like to take a pause from the tutorials to present my new demo reel for 2014. I felt like my previous demo reel was outdated, and that I’ve had the honor to work on some awesome projects in the last year and a half. I feel like this reel better represents my skills to date, and hopefully gives me enough credentials to merit me making all these tutorials, haha. I hope you enjoy, and thank you so much for all of you who have shown support! Let the tutorials continue.
The Luma ExponBlur tool actually had some buggy channels being added to your scripts (something leftover from the nuke 6 days I think). I cleaned these channels up so it will not add unnecessary bugs or channels.

This is my Feather Gizmo, I will put it on nukepedia soon:
More will come!

Here is the first part in the advanced keying series. I’ve started with the ALPHA section, and made a custom slide for just ALPHA, where you can see the many topics I plan on covering in future videos, but for now I am just covering 1.1 Pre-processing the Green Screen. Here is the slide for ALPHA:
It’s a long video, but it’s full of useful tips and techniques. I recommend watching the whole thing if you get a chance, but if you’re in a rush and want to skip to certain sections here are the Timecodes for you:

here is the Neat Video plugin website I mentioned for reducing noise on an image:
here is the link to some keying tutorials from nuke station for you guys to look through if you need them, most all of them are excellent:
Please guys, I know I covered a lot but if you have any questions, or if you would like me to do a written recap on all the sections here in this blog post, please just let me know and I’d be happy to write it up for you. Leave a comment with any questions, or if you think I messed something up, or if you’d like to contribute to the conversation and have anything to add to this tutorial. I enjoyed putting this together and look forward to the rest of the keying tutorials I plan on putting together. Please share if you learned something =)
