Curious, what programs did the majority of users migrate to(in your area)? Adobe Premiere and After Effects?
Apple SHAKE went to The Foundry's NUKE, but at the time it was still owned by Digital Domain. After Effects is not a replacement for a NODE BASED compositing system. After Effects is more geared to motion graphics and animation. After Effects can do some low end VFX, but for high CG integration After Effects is too cumbersome, slow in 32Bit or Float, and has network render limits.
Final Cut Pro went mostly to Adobe Premiere, and a lot of studios are still AVID, so they didn't ever need Final Cut. AVID is pretty slow to move forward with technology, over priced hardware, and a somewhat closed system, but very solid and reliable. Because Premiere is owned by ADOBE, which does have some video experts in the company somewhere, it is mostly a company of general tech engineers, and every release our bug list can be pretty big. I've also seen one of our editors on the phone with an Adobe Engineer arguing about something not working or crashing in Premiere, and we realized no one helping with our problem Edits, knows how to Edit, or even knows much about what editing entails. Adobe tries, but they aren't just committed to one app, but the whole suite. If you don't need to worry about any that level of reliability for broadcast related stuff, QC, tape layoffs, edge code, anything like that.. I would just use Premiere, even with its quarks, because you probably won't notice them or can work around them. If you have the whole suite, the Premiere to AE if pretty easy. Though I wouldn't use that workflow for high end vfx tv or film work, for generalist stuff I totally would, and AVID for broadcast.
