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
solution.
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.
