Hi guys,
Fuses and general scripting support in Lua and Python are available in both Fusion and Fusion Studio. External scripting is available in Fusion Studio only. The available documentation is available on our support site - we'll be updating this as soon as we can.
The Fusion Studio 7.7 and later native SDKs will be available under NDA only - please contact our developer support crew directly at developer@blackmagicdesign.com if you are interested in signing up.
cheers
