Good one Laurence : )
The big question is how is timeline preview?
Still rubbish?

OK,

I really try to be humble on the forums, but in this case, I have to say I am pretty spoiled.

I'm basically running real time. I don't have to wait for a thing when editing. I am also running SLI across three ASUS 26" displays, and can run 3-D. I've been doing that for gaming and Blu Ray play back. Really haven't done anything 3-D on Vegas yet.

But I really wait for nothing in the timeline. Old computer, hated waiting for the refresh. I can have 6 hours in a project, and just slide around and really no delay.

Rendering time is is less than project time. Standard DVD, probably 1/2 the project time.

Blu Ray, basically render time is the same as project. So a 2 hour BluRay project will encode in 2 hours. I never need to let things run over night anymore.

Peace

Michael

Puttering along on a dual core notebook, and happy as a clam . . .
;?)

System must have cost a fortune, or it least it would in Europe.
Despite a major system upgrade here including GPU graphics,
timeline is still dire.

Are you there Grazie? It's time to upgrade your beast!

Grazie has upgraded... look at his specs on his profile..not quite to a double hex core system...but still.

It could be a limitation of the compiler. 16-cores are not too common, I can't imagine that there's many 24-core PC's out there.

Don't be humble. Brag a bit. What motherboard are you using? Have you run Rendertest 2010 on it yet?

http://www.sonycreativesoftware.com/forums/ShowMessage.asp?ForumID=4&MessageID=766333

Did you by chance go into the preferences and set the number of simultaneous processes? You might be at default values rather than possible values.

OK,

I'm gonna try and run some tests with the rendertest, but need to know what I'm doing in using Vegas 11. I'm running 64 bit.

To the earlier comment, yes, I checked the preferences tab, and have it set to 16 rendering threads. Which is the max.

This has an interesting point however. As I have 12 actually Xeon cores, which support 2 threads each, if I have 16 threads, it will be split across the 1st 16 cores, which is only 8 physical cores, so I am not actually using all of the CPU cores, as 4 cores are basically idle, and the rest are doubled up.

Another interesting thing is that I have checked this more than once, and even though I am running a pair of speedy GTX 580's I guess due to the number of cores I have, processing is actually SLOWER when I am using the GPUS. I'll check drivers later too.

I'm gonna start at stock speed, which is 3.47GHz, but as I am water cooled, I have overclocked this to more than 4.6GHz. I''ll try that later.

2 quick questions, 1st, in the video preferences tab, Dynamic RAM is set to 512MB. I have 12GB in the machine, should I bump this up?

2nd question, when doing the render, I am selecting HDV 1080-60i, but the instructions mention making the render "best". Should I be picking that from the Project tab? Should I leave everything else default?

Now that this is Vegas 11, some things have changed. In picking "best" from the Project tab, and leaving everything else alone, I got 4:33

We'll see how this goes.

Peace

Michael

Okey Dokey,

Here's what I got for RenderTest

No GPU accel, 1GB RAM cache, 3:57

Lo and behold, installed new video drivers, with GPU enabled, 38 seconds.

I'll mess with overclocking tomorrow, to see what I can get.

Good Night.

Michael

We have a new champion....

I would think you could build this Twin Xeon monster for about 6-$7000 US.. Considering I once spent $3000 US on an 80meg harddrive, this isn't bad at all.

PeterDuke[i] Are you there Grazie? It's time to upgrade your beast![/I]

Not according to my RoI.

The setup I've got now has to see me through for sometime to come. When I priced the Beast, Xeons were on offer but at a humongous price.

Our chum has a magnificent animal. I'll look forward to reading what he can get on overclocking. I love this stuff!

Well, just did a little overclocking to see what would happen.

Bumped my CPU speed up from 3.47GHz to 4.16Ghz, (20% increase)

Then bumped my GPUs from the stock 850MHz to 1005MHz. (18% increase)

But only saw the rendertest go down from 38 seconds to 34 which is only 11%

Have to say, even before the overclock, the GPU never went more than 65%, and CPU Usage (the average of all cores) never went above 32%
Also, there was only heavy activity on 6 of the cores.

So I think it might just be a limitation in the code.

I'd love to find a way to take advantage of all 24 cores.

Peace

BTW, This is a recent build, and I build a new computer every 3 to 4 years, which I expect to last me as much again. I also do far more audio than video, and use tons of plugins, and in that case with Cubase, it really helps.

If I could figure how to post a picture to this forum, I would.

Michael

Michael: by default Vegas can use max 16 threads. You can, however, change the default yourself: Options & SHIFT+Preferences & Internal. Search for "Video render Threads" be sure you select the (64bit) and change at will...

I have a double Xeon quads (8 cores, but no HT) and using it
-without GPU assist there is a render speed maximum around cores x 1,5 = 12 and some 600 MB Preview RAM (Yes, it has influence on rendering speed too)
It seems that more than 12 slows down rendering.
I can get the CPU usage to some 95-100% with this setting.

-with GPU assist the best rendering speed is achieved at max threads around 2-3 (!) with around 50 MB Preview RAM (!).

GPU assist with my simple GTS 450 brings some 5% rendering speed - but only using the above number of threads and Prev. RAM. Changing the settings seems very sensitive.

Let us hear what some fine-tuning brings on your enviable machine.

Edit: Ah, yes: do you use a Windows 7 64 version that supports 2 physical processors? When I got my double Xeon machine I cursed a full day fighting to make it use the second processor - until I found out I had to install Windows 7 Ultimate since my Home Premium would not recognize the second processor.

Actually Intel has a ten core processor running at 2.40 ghz, that you can install in a 4 socket DL580 server, with up to 2 terabyte of ram.
so 4*10 = 40 cores, with HT they become 80 cores.

Downstairs, in the data center, I have a couple of 4*8*2 cores (total 64 cores) that I wanted to test with vegas 10 but unfortunately 7 supports a maximum of 2 sockets.

Anyway, it's not easy to scale with the number of available cores, since you have to multiply the I/O bandwidth in both reading and writing...

Would you be kind enough to list your parts. Especially the motherboard, cpu's, & ram?

I'm considering either building a 12 core or buying a 12 core Mac Pro. I haven't decided yet. The Intel motherboard for dual hex cores goes out of service next year so I don't want to buy old parts but I really like using Intel motherboards. (actually maybe an older more stable mobo isn't a bad idea) I, like you, build a new system every 4 - 5 years with top-of-the-line parts which seem to last. I'm just looking for stability and performance.

Thanks,

Not quite sure I understand your explanation on increasing the treads.

I'm on a PC. Are you asking me to search the registry, and edit a key?

I don't understand what you mean.

Thanks.

Michael

Yup,

I've got servers in a farm too. Biggest right now is a quad hex for 24 physical cores, 48 threads. But what I am finding is cores aren't the thing right now.

Will have a new post shortly with thread results. It's very strange.

Michael

John,

Here's a link to eVGA's Mods Rigs site, which has the full skinny on the components, and a couple of pictures.

OK,

I'm gonna start a new thread on the rendering thread topic, because something is whack.

Michael

Got a dual quad hyperthreading XEON too ( 16 cores ) and 48 GB RAM .

GPU not yet used since when rendering ( 100MB dynamic preview RAM ) all 16 cores blow at 95->100 % and renders bloody fast.

What keeps on wondering me is that vegas does not use RAM , the vegas64bit also prefers to stays below 4 GB and that tells me something . Wonder and keep on wondering why fast and lots of RAM are left aside while they can improve lots of things ( when being used ).

Will install a couple of quadro 4000 ' s soon ( bought them few weeks ago but did not yet install since had to finish few projects first ) but am solely and only interested in real-time improvement .

( see my dell T7500 workstation specs )
