It is not possible to open or export a Digital Fusion 4 flow/composition into Fusion 5 or vice versa.

A large number of changes in the internals of Fusion were made which would make writing an exporter a monumental task:

  • The DF4 flow was stored on disk in a custom binary format while Fusion 5 stores its compositions in ASCII.
  • All identifiers for tools and other objects were changed from 4-byte binary IDs to ASCSII character strings.
  • The y-axis was flipped so as to match the orientation of axes in the 3D environment. This involved making modifications to practically every single tool.
  • Many tool features and their corresponding controls were added, renamed, removed and changed. For example, a given slider with a value of 50.0 might have to be set to a value of 7.0 in Fusion 5, to produce a similar effect.

If you are planning to switch from DF4 to Fusion 5, we recommend that you plan the switch to occur in between compositing projects so you don't have to work in both DF4 and Fusion 5 at the same time.
