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 1.1: pre-processing the GS


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:

Advanced Keying Breakdown Series: Introduction

Advanced Keying Breakdown Series: Introduction

Hi all,

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:

Advanced Keying Breakdown

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:
