Actually I think Avid has been quite public about these things for a
while now. Ever since Media Composer 3.0 was launched we've been
talking about how we use the GPU and the CPU to move FX processing
back and forth. We've also been using all the cores available for both
FX and Codecs for quite some time now. This will be dependent on what
your sequence looks like and the compression resolution you are using.
Importing QuickTime into MC is entirely controlled by QuickTime and we
don't have any control of the NVidia GPU decoding of H264 streams.

Thank you Michel,
Knowing for several years that Win 7 and Snow were coming -- and
having no need for AMA until it supports AVCHD -- I've been ignoring
(my bad, not Avids) all releases until both operating systems began
shipping. (Why pay for MC upgrades that might require more paid
upgrades -- when my 2.8.4 does everything I need. And yes, it runs
nicely under 10.5.8.)
Now that both 7 and SL are shipping and are installed on new computers
-- PLUS many new computers have Quad processors -- I wanted to check
that MC could make use of the performance provided by these new
systems. (Of course, Windows 7 is still unsupported. Hopefully,not for
much longer.)
For the Mac, the Avid site says for 4.0.4:
OS: Mac OS X 10.6.2 (Snow Leopard)
1) Does this mean one can run SL in 64-bit mode?
2) Does it mean that MC now actually uses task/buffers larger than
4GB? (Is MC still Carbon like FCP -- or is it Cocoa?)
Lastly, there are new quad-core hp laptops that use the GeForce GT
230M with 1GB of VRAM. Since VRAM can be used to buffer input and
output to/from GPU FX logic -- this would seem to be a real help with
HD RT FX. Looking at the Avid site -- it's showing only "NVIDIA Quadro
FX family (FX 560 or higher)". Which raises two questions:
1) Does MC make use of all the VRAM that is available?
2) When will these new NVIDIA chips that have, for example, HD
PureVideo plus HDMI with HDCP be supported in addition to the Quadro
FX chips that frankly aren't being included in any of the new laptops?
Lastly, I'd be curious how much performance increase folks notice when
moving from 10.5 dual-core to 64-bit 10.6 i7 quad-core systems.
Benchmarks show 3X greater performance -- although moving-up to 8GB
RAM played a big role when multiple applications were OPEN at the same
time.
Time is closing on an end-of-the year investment.
