Nigel, I am going from a G5 Quad to a new Mac Pro 2 x 2.4 Ghz and from FCS2 to 3. I assume the Mac Pro is going to blow me away with its speed, especially producing h.264. I can't find any info on how this Elgato stick works in terms of using the CPU of the computer.
What I'd like to know is: will the Elgato HD substantially improve compression time even on the newest mac Pro's? (and how does it do it, if you will...) |
The newest 12-core MacPro towers I can't tell you, but it's faster than my 8 core when it comes to producing h.264.

When it comes to h.264 the number of cores doesn't make that much difference.
In the recent update to the Pro Apps Apple included a Compressor setting for the iPad, which is 14 Mb's, but YouTube and Vimeo, for example, won't accept anything above 5 Mb's, and that doesn't stream very well on the iPad. I'd like to hear other's experiences with encoding for the iPad, with or without Elgato's Turbo.264 HD. |

So please elaborate, Chuck. |
I don't know that much about the intricacies of h.264 and mp4, but I have a couple of X-Serves and use Qmaster to render XDCAM projects across about 48 processors. I think XDCam is some flavor of Mpeg2 and when I submit the job the fans kick in, the processors are pegged, and it renders quickly.
When I distribute h.264 encodes across the same Qmaster network the fans barely make a burble, the processors vary between 30 and 50% and it takes significantly longer. I'm sure there's a programmer who can explain why this is, but h.264 really benefits from hardware acceleration. Come to think of it we render .mp4 files for a producer that uses the WDHD player and it max's out the processors too. Isn't h.264 Apples version of .mp4? |
