The Image node - Part 4 - Using External Mattes - Flame 2019.1

Part 4 of the Image toolset shows you how to deal with external matte inputs as well as embedded channels when it comes to working with the Selectives in the Image toolset. The Image toolset does have its own masking and keying tools for image isolation but it’s also quite common to be provided with external mattes/alphas or even multi-channel media for flexibility. These assets can be a major help when it comes to isolated look development but there is a certain workflow you need to know in order to use them with your media in Flame. Please note that external Mattes and RGB matte passes are currently only supported in Batch and BatchFX. They are not available in the Image TimelineFX.
