Advanced Keying Breakdown: DESPILL 2.1 Initial Concepts

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

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

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.
