A guide to realtime performance
We work in a Broadcast environment using Digital Betacam for SD production. Working anwhere from HDV to Sony SR in HD.
I know it is a difficult question to answer but I am having trouble getting a indication of the realtime perfomance of Final Cut Pro on a given system.
At NAB they cliamed to have 8 streams of HD playing in realtime in a final cut pro. As there were about 50million people at the stand it was not possible to ask questions.
At this stage I am not contimplating a io card with hardware FX (ie. Cinewave). I want to see what a G5 is capeable of. I understand this is a complicated issue. Depends on processors, RAM, video card, format, storage…etc…etc…etc. But there has to be some kind of general rule or guide line.
On the fastest avilable G5 (currently a Dual 2.7 with 2BG RAM decient video card) with a dual channel fibre storage (ie Huge). Or even use Xserve as an example. What realtime perfomance can I expect with:-
1.Uncompressed 10-bit SD PAL
2.HDV (Working native. Which I believe the latest version of FCP does).
2.Uncompressed 10-bit 4:2:2 HD 1080
3.Uncompressed 10-bit 4:4:4 RGB Dual-link 1080How many streams of footage could I play in realtime? How many graphics layers? How many effects (Keying, CC etc.)? I understand given the variables that it not possible to give an exact answer. But I would appreciate a guide as to what is possible.
OR.
If anyone has a example of there system and performance, that would be greatly appreciated.
Thanks
Denzel

Kind of a hard question to answer w/o knowing the specific Mac/RAM/Storage you intend to use.

This is the responce I seem to get from everyone. Even apple and the resellers. Grrr. Forgive my frustration. =)
Surely someone has a FCP system running and they can tell me what its performace is?
If you want, I am looking at Dual 2.7Ghz G5 with 2GB RAM, Professional Graphics card and Huge System Dual Fibre storage.
