I’ve consolidated all the Advanced Keying Videos to a single playlist on Youtube so you guys can easily view them in order and all in 1 place. This should make it much easier to pass around to people, or to revisit them all at once.
I’ll work on getting them up on some other media sites like vimeo for those that down particularly like youtube.
Matt from CoreMatte.com was kind enough to do an interview with me about my work in the VFX industry and my tutorial blog.
I recommend you check it out if you want to learn a bit more about me and my background in VFX as a compositor. This was my very first interview and I am truly honored. I also recommend checking out the rest of corematte.com for more interviews and tutorials!
Thanks Matt for taking the time to put together this interview.
Hopefully I will have more tutorials out for you guys soon.
Explaining Premultiplicaiton and unpremultiplication. Breakdowns of Over and Addmix, and tricks to gamma the alpha before overing. Also at the end, talking about the importance of unpremulting before color corrections (wrong and right ways to do CCs).
This tutorial uses basic colors with a transition to teach these merging techniques and the math behind them. The math and techniques are the same for complex images and alphas, but I felt it was easier to demonstrate this way. If you are bored by the beginning sections (they can be a bit basic), I’d highly recommend skipping ahead to the “gamma-ing the alpha before an over” section. I Hope this de-mystifies some complex concept of merging images, and how to use the addmix tool.
Should be 1 more tutorial left (with a possible bonus to the despill section), presenting a template script and explaining how I have put together all of these concepts we have discussed in order to bring a full key together. This includes tips and tricks to getting around common problems in keying, despilling, and merging. I hope to have this to you guys soon.

30:25 Unpremulting before Color Corrections
Thanks for all those that are watching and learning. I am really glad I can help.
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 I felt like my previous demo reel was outdated, and that I’ve had the honor to work on some awesome projects in the last year and a half.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!
VideoCopilot’s 04 tutorial is about the basic after effects interface, and so I thought I’d do something similar. But instead of reinventing the wheel, I thought I’d just point you to some super useful Nuke tutorial “playlists” if you will where you can quickly learn the basic interface and workflow within nuke.
Here are some links to help you guys pick up the Basics:
for just basics:
For some broader tutorials use this:
That page is really all you need to know, but hey, why stop there?
tons of great videos there.
Also a great free resource!
I just found this one to be handy for users coming from AE or other comp programs to get a general sense of what nuke can do and some interface tips/tricks. It’s even called “STEP up to Nuke”:
Hope all those sites and videos will hold your thirst of knowledge for awhile. Shamefully, I haven’t even seen all these incredible videos yet, there are tons! Slowly but surely though, I will plow through them all.
Knowledge starts with the heart. So get passionate!
Different artists have different workflows. But I think most can agree on common practices that make nuke run faster, and stay more organized, allow you as an artist to do your thing and output renders quickly.
I have my own list of Steps I have written sort of as a compositor’s Checklist. I believe I posted this checklist in a blog awhile back, but I will give you guys the link to check it out. I strongly suggest you write these down and keep them on your desk at work. It is invaluable when you are starting out. The blog was down so I’ll just post it here:
I am also going to link you guys to the 2 most useful articles about nuke optimization I have read online. Both have saved me tons of render time and have made my scripts more organized and easy to navigate. Links Down Below.
