I have used Sony Vegas Pro as my primary editing software for almost a decade. More recently, I have been dabbling with Hitfilm 3 to accomplish some special effects that are difficult or near impossible to composite in Vegas without the Hitfilm 3 plugins. Very recently, while trying to replicate a composite video scene using practice green screen footage from the Hollywood Camera Work website, I found I was not able to accomplish it using either Sony Vegas or Hitfilm 3. When I went back and reviewed the HCW VFX compositing course workflow, I saw that the instructor used a node-based compositing software called Fusion. I decided that I needed to investigate the possibility of learning node-based compositing, so I went searching for the Fusion software. To my pleasant surprise, it turns out that the company that now owns the software is offering a FREE version of Fusion version 7. Although the free version is for stand-alone use on a single workstation (no networking or 3D capabiliies), it is still a very powerful and complex node-based compositing system that has the tools and functions to make professional grade VFX. I should also mention that Fusion has been used by the movie industry for over two decades to put together effects for many a great motion picture. I'm writing this news blurb here on Digital Director to let everyone know about the free availability of this very powerful VFX software. You can download it from this website: Black Magic Design Fusion 7.
I've been playing with the software for less than a week and I'm fairly excited about the power of node-based VFX editing. I'm not pimping their product,just sharing my good fortune with my friends here. In the help section of the software there is a 331 page .pdf user's manual. There are also so very fundamental Training Videos.
