HeyGen open-sources HyperFrames' Keyframes animation tool
By Steven Van ·
Run it via npx to let an AI coding agent inspect and correct generated motion straight from the command line.
HeyGen has open-sourced Keyframes, the animation system behind its editor's pro tools, as part of HyperFrames. It runs from the command line with npx hyperframes keyframes, letting an AI coding agent inspect motion it has generated and correct it directly rather than through the editor UI. HeyGen positions it as usable by beginners while going deep enough for After Effects users. Read the announcement for more, and see HeyGen's page on Creators Toolbox.
