We need to mention here that Sony Vegas uses MediaConcept software to accelerate encoding.
That part didn’t get updated from Dec 2010, so it does not work with nVidia cards newer than Fermi generation. Those Quadro’s are not that bad priced now (on eBay). But true, some of GeForces from that generation will work too. -
I would agree, but if you render with GPU and CPU ‘waits’ for the GPU, that that would have to be at 100%.
If none of the CPU or GPU is not at 100%, then probably they both are waiting for the HDD to read and write the file.If that is not the case, then definitely the encoder is not optimized. The higher the video compression, the more paralleling can be done.
For example you can start rendering 1000 slices simultaneously, if all of them start with a ‘I’ frame. -
First of all, the process of transfer from video camera via firewire is a coping process, not capture.
Importing that file into Vegas involves a decoder. You might have something in your new desktop that conflicts with that. Did you had installed on laptop something else?
-
The issue is that in both cases, the CPU utilization should be at maximum, for the most efficient encoding. If is not at 100%, there is a bottleneck in some other part of the system that needs to be found.
Usually is a slow HDD (green generation). -
Maybe your bottle neck is the HDD now? Is it a newer generation internal SATA one? Is it labeled “green” (it means slow)?
Use “Resource Monitor” while rendering to see what is happening.
Also, you can use GPU-Z to monitor the video card GPU utilization. -
Some eBay auctions ship in Spain.
You can get an Fermi-generation Quadro 2000, 4000, or GTX 400 series, or one of the ATI cards listed in my previous post. -
[Heinrich Himmel] “In terms of CUDA performance, I believe that the GTX 780/Ti/Titan and GTX 970/980 are the only ones that will outperform the GTX 570/580. Of those, I would go for the GTX 970.”
Probably they won’t work at all with MainConcept encoder, they are not hard encoded in it.
Sure they will work probably with some CUDA effects (and ATI won’t do that), but the encoder was not updated from 2010.I think the best nVidia is still a Quadro 6000 due to memory size and floating point performance. A Tesla from same Fermi family will probably work the same, but I didn’t have any information on that.
With a quad Xeon CPU I cannot even stress my Quadro 6000 above 25% utilization… CPU cannot “feed” it fast enough.

No, too old.

If you have any of those listed by MainConcept (see the above thread), it would work best.

ATI drivers are know for being “temperamental”, new is not always better. Plus, newer video cards do not work as expected in Sony Vegas:
