I recently upgraded (well, for me it was an upgrade) to an older Mac Pro
Processor 2 x 3 GHz Quad-Core Intel Xeon
Memory 16 GB 667 MHz DDR2 FB-DIMM
Graphics ATI Radeon X1900 XT 512 MB
Software Mac OS X Lion 10.7.5 (11G63b)
I have installed FCP 7.03 (and in a seperate folder the hated FCP X)
I also have Adobe Creative Suite CS6 installed.
On my previous MacBook Pro I could export from a video sequence as a Flash Movie (.FLV). I could do this using one of the options in "Export Using QuickTime Conversion" On that machine I was running Flash CS4.
For some reason the Flash export option is not showing now. Flash is properly installed and opens just fine.
