Blackmagic Fusion (formerly eyeon Fusion and briefly Maya Fusion, a version produced for Alias-Wavefront) is |post-production| image compositing developed by Blackmagic Design and originally authored by eyeon Software. It is typically used to create visual effects and digital compositing for movies, TV-series, and commercials and employs a node-based interface in which complex processes are built up by connecting a flowchart or schematic of many nodes, each of which represents a simpler process, such as a blur or color correction. This type of compositing interface allows great flexibility, including the ability to modify the parameters of an earlier image processing step "in context" (while viewing the final composite). Upon its acquisition by Blackmagic Design, Fusion was released in two versions: the freeware Fusion, and the commercially sold Fusion Studio.
Fusion is available for Linux, Microsoft Windows, and with the release of Fusion 8, macOS.
