Bottleneck in rendering speed or not?
Hello.
I got a new computer and anticipated nice rendering speeds, but it’s not going so smoothly as desired…I already read some far out analysis on the same issue on this forum and tried to apply what should be done, like having source materials on an external hard drive and rendering onto another one, dynamic ram to 1 gig and 8 threads, but still I cannot get much anywhere.
My system is Samsung RF711 laptop with i7-2820QM, 8 gb ram, Nvidia GT540M videocard.
I’m rendering an uncomressed AVI into MPG with Neat Video filter and Unsharp mask and levels internal filters.So the results are as follows: When I render with all the filters on, cpu is average 24% engaged.
When only Neat video filter, then average 50%
Without any filters average is like 65%So why is that? I can understand that the internal filters are slowing it down alot, which is as shame because how can Vegas not update the filters and claim that they are supporting multiprocessing, but still, even with all the filters on there’s like 30-35% laziness 😉
What else can I try? Is there anything I can do more?

Sorry….from what i can see, there is nothing you can do
more. Vegas developers has got to iron out some serious issues,
with some tangible updates.Steve Rhoden

It’s really hard to say but if you have uncompressed AVI on an external hard drive, my guess is the CPU is not the bottleneck, your disk IO is.
Are you using firewire or USB to connect the drive? If you want to work with uncompressed video you really need a RAID 0 array and eSATA connection. Try testing with a codec like DV AVI on a file that is on your internal hard drive and see if you still get slow renders when adding FX. Even better, add the FX to generated media and see if your CPU utilization is still low.
Also note that NeatVideo will slow down your rendering times significantly and I’m not sure how multi-threaded that plug-in is.

Ok, I figured it out!
And thanks John, you helped me to do that.So I did the testing and what came out, I take my words back, Vegas is doing a great job! When I added the internal filters and rendered to mpg onto my desktop having the source file also on drive C, the processor started running on 94-97% and it was converting like anything, haven’t seen such a speed before in my life! But I did test it before the first post also, I don’t know what went wrong…
So the culprit is Neat Video filter, that slows it down like to 20% of processing speed. But I’m glad to figure it out and also I noticed there’s a new version of Neat Video out there, have to check it out, if it’s really working as much faster as they are promising, then seems like I have to go for that. -
Yea. NeatVideo can definitely slow things down. Thank’s for the heads-up on the new version 3.0. I see it has GPU acceleration now. I’ll have to check it out.
