…good choice, but no need to go HQ for SD-resolution, SQ will do also for SD-work.
We switched a couple of weeks ago completly to ProRes for SD-editing. Since then we edited 4 TV-Shows shot on digi-beta with ProRes SQ settings.
No one can tell the differnce between 8-bit uncompressed SD and ProRes.
But you have the advantage of 4 times less space+bandwith needed on your raids.
therefore editing in ProRes feels much more speedy, even on a G5.
The 10bit codec gives you even a better picture quality, especially if you do a lot of effects & grafics.
