They told me that rendering time was a thing of the past, and that FCPX would accept any format and play without a hiccup. Just toss it in the Timeline - any old format - it'll play straight out of the box.
What they failed to reveal was that all the transcoding and rendering and analysis has to take place up-front. So, as far as I can see, to be properly prepared to edit in FCPX, there are hours of interminable copying and analysis to be endured.
They said it would be happy with HDV. It is not. It won't import.
I can, however, see myself using it for composites - montages and multi-layered scenes because of the speed of the 64 bit processing. And it is fun to watch the Activity Monitor flashing "64 bit" in triumph.
And how come there's no way of getting video out of a card - in my case Blackmagic - onto a proper HD monitor? That doesn't seem to have merited any attention whatever. Did someone forget that?
Maybe it's just me, but I also find the GUI kinda sluggish. And I'm on an 8 Core Dual 3 ghz, so I don't think it's me. But the rendering really is fast. That's it! I'll use it as a Render Farm.
It's a bit of a con trick, if you ask me.
Best wishes,
Harry.
