bearguy9, I agree with you that FCP7 is terminal so those still using it must plan to move on. But the schedule for this will be different for every user, and the destination too.
So far, with a little help from Resolve (which can input and output 16-bit TIFFs, as FCP7 can't), I can do all I need using FCP7. I don't need anything offered by any Mac OSX's past Mountain Lion. If not for my eSATA card working unreliably under Snow Leopard, I'd run FCP7 only under Snow Leopard, where FCP7 really works well. Besides avoiding the playback problem described in my last post, FCP7 renders about 15% faster under Snow Leopard than under Mountain Lion. A beauty of the Mac is the ease of creating boot volumes, so I can shoot into the Mountain Lion volume running Resolve, make some .mov file, and shoot back into the Snow Leopard volume to use the file in FCP7. This game will work until the FCP7 has some serious incapability. This might already have happened for people who need to edit H.264, which FCP7 does unreliably. I don't need to edit H.264. Every user has different needs.
Likewise bearguy9's embrace of Premiere won't be every FCP7 refugee's choice. I'm reluctant to move to any Adobe software since I distrust Adobe's color science and abhor the GUIs they inflict on users. bearguy9 can't ignore that some professional FCP7 refugees now use "iMovie Pro". I'll look at Avid. Editing software is an intimate tool and none might ever fit like one's first.
I don't want to lead anyone forwards or backwards. I posted earlier today with a simple observation about bad FCP7 playback under Mountain Lion and Mavericks. Somebody has already marked it: "This helped me". But that doesn't help me. I need to learn if it's just my systems havng that FCP7 playback problem.
