I have a system with this spec
CPU Dual xeon x5550
MB supermicro X8DA3
Ram 12x4GB 1333 ECC Reg
HDD 1x300 GB SAS for OS and apps and 6x1TB(raid 0) SATA for project
VGA Quadro FX 3800
OS windows 7 64bit
Now my Q is can i use Mercury Playback engine? if yes how to enable it?
Both of you will have to wait for details to become available in due time. MPE is a future planned addition, with the emphasis on future and planned. Nothing more, no timing, no indication it may be added to CS5, 6, 7 or 8. Just wait and see sometime in the undefined future.
Has Adobe released a Mercury SDK for plug-in developers yet? I love my plug-ins and can't think of the last time I rendered something without a 3rd party plug-in? It would suck to lose all GPU acceleration when using a plug-in.
Since everyones having to do plug-in rewrites for 64 bit only CS5, why not include MPE since there recoding anyway?
Just let me remind you that the move to 64 bit for CS5 is a major undertaking. The development of MPE is another major undertaking. It may be (I hope not, but who knows?) that to combine them leads to delays that are not wanted. In that case the clever approach may well be not to delay CS5, but add MPE at a later date with an update. Personally I rather have CS5 without MPE at NAB, then CS5 plus MPE at IBC.
