Advanced Keying Breakdown: DESPILL 2.2 – Despill Techniques

November 20, 2014

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!

 
0:00 Keylight for despilling
6:00 Adding luminance back
11:45 Using BG luminance
15:51 Despill matte desaturate fix (finding max of each channel)
18:42 Hue correct for despilling
23:03 Comp example with different despills
28:46 Combining despills
31:10 Bonus: Alpha gamma before over
34:01 Comparison, final thoughts

Thanks for all your support!

Advanced Keying Breakdown: DESPILL 2.1 Initial Concepts

July 28, 2014

0:00 intro
0:40 what is despill?
3:40 Separating the Despill process from the Alpha process
7:33 Core Despill and Edge Despill

Hey guys,

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

http://nukestation.com/vkeyer-tutorial/

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.

Advanced Keying Breakdown: ALPHA 1.4 – IBK Stacked Technique

July 19, 2014

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).

0:00 Intro
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
37:12 Outro

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.

Cheers,

Tony

Advanced Keying Breakdown: ALPHA 1.3 Channel Math / Combining Keys

May 13, 2014

0:00 Intro, RGB channels
6:00 Luminance
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:
ChannelControl_v05_

Here is the Adobe After Effects Matte Technique Gizmo:

My next video should wrap up the alpha section, stay tuned.

Tony Lyons Demo Reel 2014

May 5, 2014

Hi guys,

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.

Cheers!

Advanced Keying Breakdown – ALPHA BONUS: Eroding and Feathering Mattes

April 29, 2014

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!
