BorisFX provided the primary CG/FX plugin for Media100 going way back, starting with Graffiti and later RED. Media100 passed hands a few times over the years and was last bought by BorisFX. They did some fixes and updating but their resources focused on the more profitable FX plugins and never transitioned Media100 over to 64bit. Most recently, BorisFX acquire the planar tracker Mocha.
Early Media100 relied on custom hardware add-ons, like the various Amiga NLEs. Later on, a software only version was released. It was very usable on my lowly PowerBook G4 with an external drive.
Porting wouldn't be easy but Media100 provides an existing NLE framework for adaptation. Would it be easier to adapt or start from scratch? Maybe like choosing between porting Firefox or creating a new browser. It'd be great to taking an existing Amiga NLE like MovieShop and update it, but source isn't available.
Migrating just the Mac version to 64bit would appeal to current Mac users, but it could provide a revenue source to help offset the efforts and generate more interest on the Amiga side.
Anyway, Media100 is there if someone with the skills, resources and motivation wants to look into it further.
