Combustion was a computer program for motion graphics, compositing, and visual effects developed by Discreet Logic, a division on Autodesk, and originally released in July 2000. ^[1] It shares a timeline-based interface and also a node-based interface with Autodesk Media and Entertainment's (formerly Discreet) higher-end compositing systems Inferno, Flame and Flint. This is in contrast to the exclusively either layer-based or node-based interface used by some other compositing applications.

Combustion was a support software tool for Flame and Inferno. Combustion was a superior software tool for vfx frame-to-frame painting, with some of the functionalities still not currently included in other compositing software in 2019^[clarify].

The last version of Combustion was Combustion 2008. The end of its development was never officially announced, but the company was known to be concurrently developing a new compositing platform, Autodesk Toxik.^[2]
