HDW : As a Final Cut Pro user I find this very tempting indeed. In the early days I used Premiere 6.5 moving over to Premiere Pro 1.5 then onto Final Cut Pro. I found Premiere Pro overly complicated with a lot of finicky controls very like Photoshop. The NVIDEA Quadro FX4800 for my MacPro would cost £1500 then add the cost of CS5 and you are looking at an upgrade price of around £3000 !
This new 64bit Premiere Pro with the Mercury Playback Engine is fantastic it’s the first NLE package to be able to run 4 streams of native 4K RED files as a multi-cam production…nothing can touch this as far as I am aware. 9 streams of P2 full HD footage in real time, this baby will bring HD editing beyond the 21st century.
Apple are a long way off bringing FCP anywhere near 64bit and as it stands Compressor and DVD Studio Pro are a joke. The one sole program that saves FCPs butt is Motion. Motion is streets ahead of After Effects and far easier to use but for this one program I for one would kiss good-by to FCP and who knows if the £3K became accessible that jump may be sooner than later.
