Would the new iMacs be sufficient enough for AVCHD editing using ProRes? Sorry in your post on the previous page you said the CPU isn't enough I don't know if you were referring to the Macbook Pro processor or the iMac processor as I'm interested in getting an iMac.
iMacs support: 2.66GHz, 2.93GHz, or 3.06GHz Intel Core 2 Duo processor
I would think that even the 2.66 would be sufficient and the 4 GB RAM that it comes loaded with along with the video card, although the new nVidia video cards that support Cuda are perfect for video editing. It sends processing power from CPU to GPU because graphic cards are not utilized for rending usually just for play back and with this technology something that takes 4 hours to render can take 45 min. It also handles AVCHD encoding very well I understand.
And regarding HDSC cards:
In trying to understand this flash technology, what advantage would a faster memory card have? I mean a faster card is not going to record higher quality obviously, it could take longer to write to the memory, but you wouldn't be using a card that the camera couldn't keep up with right? In other words, if it's able to record AVCHD it's able to record it right? How could one card be better than another as long as it's able to handle the data rate or that the camcorder isn't writing data to the card an hour after you've finished recording. The only advantage I can think of is it would be faster transferring it from your card to the computer.
Do the SDHC memory cards ever have any problems?
