Its called Hyperthreading, a feature that Intel is using it from more than 10 years in all their CPU's. A 4 cores unit CPU is being seen as 8 with this feature. They said its improving the speed by little. I told you this for information, problem is that when I render in Camera Bag the 4 cores are on 50 per cent only. I did install the Camera bag Cinema 1.0.600 I'll see how this works. Thanks.
Another question : The Apple Pro Ress 422 HQ in my Final Cut ProX is giving much larger files than Camera Bag for the same codec render - Pro Ress. What kind of Apple Pro Res is Camera Bag giving , because there are 3 of them - PRO RESS 422 HQ, PRO RES 422 and PRO RESS LT.
