cmiVFX Debuts Autodesk Flame Advanced Keying Concepts Video

Princeton, N.J. - cmiVFX | cmiStudios has unveiled a new video for Autodesk's Flame (IFF) product line. The training video covers the process of creating custom keying tools procedurally with the Batch tool set. All keying tools inside of Flame are discussed, and then reconstructed for isolated control for a variety of solutions, reveals a representative.

Deconstruction of the components in high-resolution 4k image sequences allows for the reassembly of custom channels to create unique chrominance for the newly constructed image data. cmiVFX takes the viewers of this video outside of the (matte) boxed in lifestyle of standard keying tools, says a representative.


The video includes:


Rewiring Channels:

In this chapter, the video explores the core components of a standard image data, andhow to manipulate this data by reconstruction the order ofhow its assembles for more intense isolation of light and dark values.


Key Compositing:

Compositing is the core principle of the assigned task. Everything artists do is based on the concept of layering information to create new and unique information. The video shows alternative ways of layering information in order to start creating our own custom keyers that could handle anything that is thrown at it.


Build A Keyer:

Viewers can build their own custom keyers inside of Batch. Learn how to assemble a workflow for a basic green screen keying



Duplicating Channels:

According to Flame and the way it handles RGB images, there are 4 basicchannels. Red, Green, Blue, And Luminance. The video will explore the manipulation of these simple channels while creating new image data for later keying solutions.


Creative 2 Channel Apps:

Extending the previous chapter at great length, this part of the video discusses the usage of less then 3 channels to create keying solutions for

full color image sequences. Brief discussions about Canon And Red camera shots are utilized here.


Multiple Keyers:

The fact is, you can design a large detailed keying solution in once pass at great cost to your personal well being, OR you can create several smaller keys isolating specific areas and assembling later with the compositing techniques discussed in an earlier chapter. This method is usually a lot faster to complete and higher quality then the previous method alone.


Alternatives To Luma Keying:

Luma keying is a very basic keying solution when using the default Flame Luma Keyer. The video shows you the new and improved way of isolating data with a higher range of controls to pull isolate item keys in busy backgrounds. The video also explores some additional usages for effect shots using directional luminance from an image sequence.


Modular Keyer Basics:

The video demonstrates how the Modular Keyer is very much like creating your own custom keyer in Batch.  In fact, most of the tools are identical. It takes you through a typical key using the Modular Keyer and corollate it to methods discussed earlier.


Edge Wrapping Type 1:

There is still a lot of work to do after pulling a key. If your footage wasshot with proper lighting and the construction of the CG backgrounds were done with care, then maybe your job is a bit easier. However, complicated back lit background plates with slightly off lighting on the foreground plates will take a bit more work to complete. We show you a common method of melding the two layers together with a slew of batch tools.


Adding Bleed Controls:

This Chapter takes over were the last chapter left off. When creating some dynamic post lighting tools for better seaming of your key solution, you will need to incorporate low level slider controls for dynamic client feed back. We reconstruct the previous tools to better accommodate the client artist relationship.


Misc Compositing Tools:

In this chapter we sum up all the other chapters while focusing on some of the extra tools used in some keying solutions. Some of these topics include tracking, stabilizing, and a in depth discussion on all the math operations of a compositing solution.
