Advanced Keying Breakdown – ALPHA BONUS: Eroding and Feathering Mattes

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.

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:

Please guys, I know I covered a lot but if you have any questions, or if you would like me to do a written recap on all the sections here in this blog post, please just let me know and I’d be happy to write it up for you.   Leave a comment with any questions, or if you think I messed something up, or if you’d like to contribute to the conversation and have anything to add to this tutorial.  I enjoyed putting this together and look forward to the rest of the keying tutorials I plan on putting together.  Please share if you learned something =)

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:
