0:00 Intro, RGB channels
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 I felt like my previous demo reel was outdated, and that I’ve had the honor to work on some awesome projects in the last year and a half.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 =)
Advanced Keying Breakdown Series: Introduction
So I knew I wanted to do a keying tutorial awhile back, but I didn’t want it to be the same old crappy keying tutorial that you always see online. The teacher always talks about how to use the tools, and not about the main concepts or techniques behind them, the end result, what we are actually after.
I have put together this introduction video, and a part 1 video “ALPHA 1.1 Pre-Processing Greenscreen”, as a push to get this stuff out to you guys. Here is the Slide in the video for you guys to save for your own use:
The 3 main parts are ALPHA, DESPILL, and MERGE OPERATION.
Here are some time codes to skip to in the video if you so please:
2:50 ALPHA section
4:49 DESPILL section
7:27 MERGE section
I will go into all of these in far more details, this video is just me talking and doing a rundown of what to expect in upcoming videos.
I recommend you guys browse through the following videos on Nukestation (a GREAT website and central location for nuke tutorials) if you are new to keying or compositing. The video I am doing is quite advanced, and you’re probably going to want to get a firm grip on the keying tools in nuke before watching.
In particular, I think you guys should watch this video by victor perez:
I have some exciting news!!
The blog is now CompositingMentor.com
A new name accompanied with some new tutorials to christen the site.
It’s been a few months, I’ve been working hard both at work and on side projects, one of which is the daunting task of categorizing and analyzing all of the gizmos and tools on Nukepedia.com. I came up with a good workflow to check the tools, and I am going 1 category at a time, but it is pretty time consuming.
I’ve also been working on an Advanced Keying Breakdown, which I will be posting for the next month or so. It is very in depth, more than I have seen from any other keying tutorial yet. It focuses on the concepts and techniques of keying, rather than specific tools.
If you like what you have been seeing on this website, please share with others, I’d like to get these tutorials out to anyone who needs them. Thanks!
Without further adieu,
Welcome to CompositingMentor.com
