Vegas 7.0 Rendering - not using full CPU resources

[tarrickb]

Hello all,

I recently upgraded my PC and while rendering a project (DV to CBR MGEG-2), I've noticed that my CPU seems to be under utilized as task manager reports only 20%-40% of my CPU being used.

I am running Sony Vegas 7.0e and have a quad core Q6600 processor with 2 GB of RAM (also running Vista).

Any insight into this problem, or is this normal?
Thanks.

If you're frame serving that's pretty common. Often the bottleneck is coming from Vegas sending frames to the Mpeg encoder. It isn't really Vegas specific, lots of apps do this. You can test it by rendering to a lossless codec like Huffyuv, then encoding the resulting AVI in your Mpeg2 encoder. If the CPU utilization increases and the Mpeg2 encoding time is faster, you'll have identified the bottleneck.
