Heres a tutorial about how to despill in ways to customize the color of the despill. We move away from gray despills towards more useful colors, such as the BG or the subject. Here I go over keylight, huecorrect, talk about keeping luminance values and using the BG’s Luminance to affect the despill color. I then talk about combining despills just like combing keys, and show a little trick with the alpha’s gamma prior to merging over. More to come!

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).

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.

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.
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 I felt like my previous demo reel was outdated, and that I’ve had the honor to work on some awesome projects in the last year and a half.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.
