Hi there

Really interesting answer – Finally someone might be able to explain the problems I have been having!

I am using machine with an i7 processor, 8 gig ram, vista 64 bit.

I am capturing HDV footage into Premiere Pro CS4 as mpeg format 1080i. I have been doing a bit of colour correction on the footage both in Premiere and After Effects. When I come to export the movie as either a WMV or MOV through media encoder, the rendering starts off super quick (I can view all 8 cores on a widget on the screen), but then the processor usage will suddenly drop down to only using 1 core (and the ram usage will shoot up), the rendering may or may not kick back into using the rest of the cores, or it may just hang and never finish.

The effects arent complex on it, so have been wracking my brain as to why media encoder is having such a tough time.

Do you think the fact I am using captured HDV footage might be the problem here? If so, what would you use to convert it?

Many thanks in advance
