Render Time faster with Dual Proc?

Joseph69 wrote on 1/16/2004, 9:40 PM
Sorry to ask a much asked question about improving rendering times.

With respect to rendering AVI to an MPG2 movie from Vegas, is it true that that Dual 64 bit processors is the way to go...........?

With respect to Rendering the actual DVD........in DVD architect, just prior to burning, Is it true that the some of the 64 Bit processors are designed to encode to MPG2 directly & thus faster,............?

Neither Vegas 4 or DVDA are optimized for 64 bit processors--yet. That may be coming in a future release. But the general belief now as I understand it is that a single Pentium at 3.2Ghz will perform better than the dual Athlon 64s. I have dual Athlon 1800s, and the only time that they will speed up rendering time is if I'm frameserving from Vegas into CCE Basic. If the video is complicated enough, Vegas will take up one whole processor, and CCE will be using a percentage of the other.

Thank you
I take it that you refer to Pentium 4?
What is CCE?
My comptuer is P4 at 2400, with 1GB ram is there such a big difference if you have a speed of 3200
?
Is there then a place for Dual Pentiums, or some special Canopus card which claims to render in real time?

Sorry I am such a novice
I just make small medcial movies, & some of them require overlay of X rays, with live fooatage, text, then voice over editing

Concerning Hyper Threading, can't we simply "split" the job between the two threads?
Joseph69 wrote on 1/17/2004, 2:10 PM
I dont know what hyperthreading is, I just need to configue a second computer system which can render more quickly, & especially encode the DVD, because I may have 4 3o min films, with chapters

Hyperthreading as-in making your computer work harder/faster is partially true, partially marketing hype. Intel is famous for s t r e t c h i n g the truth as to how fast their processors are. In a nutshell the newest Pentium 4 chips have hyperthreading, but not al models. You need to read the fine print. Hyperthreading is basically the abilty to do more than one thing at once. The hype part comes from the fact not every task a CPU does can benefit from hyperthreading. Look for it in the promotional material on the computer you buy Should have a sticker sayings so.

If you main concern is how long rendering takes, the faster your CPU's raw horsepower the better. Also consider building your own PC. Its much simpler than it sounds, you only need a screwdriver. So as you may have guessed you really just assemble the computer. Tons of thread in the forum on that topic.

As far as encoding for a DVD, that Vegas can do on its own. You'll end up with a file that can be MADE INTO a DVD, but with a twist. You'll still need some DVD Authoring software (or Nero a DVD burning application) to convert the compliant MPEG-2 file Vegas makes into a a format that can be burned to a DVD. Such DVD Authoring software makes the needed image files and allows you to add chapters to navigate the DVD.

Thanks for those insights & fir your time.
Can you then tell me the basic ingredients for the ideal PC I could build which runs Vegas & renders optimally

do I need a Xenon processor, an Opteron 64 Bit Athlon, or just a P4? Is it true that Pentiusm cant take more than 1 gb ram?



As far as DVD Authoring soft ware, I have Vegas Architect, but it seems very slow

What is the best Authoring program? I have good Reel DVD but I dont understand this business of having to render separate streams

I know Adobe have recently made some super dooper DVD authoring program that resembles photoshop...........more to learn !
The DVDs I made with Nero, didnt work in DVD players

Thanks for your further thoughts

P4 seems the way to go in general. They can take more than 1 GB of RAM. The 800MHz bus should wind the wick up a tad as well. Don't blow all your money an the very fastest processor, you're paying for the boast value and not much more.
The slowest part of DVD creation is encoding to mpeg-2. Good encoding either takes time or involves expensive hardware. Mpeg-2 uses temporal compression, it has to span mulitple frames, ideally several times, to work out the best way to encode the sequences of images.

Mpeg-2 is not a simple thing like DV, it can contain multiple video, audio and text streams. Normally each one is prepared separately then muxed together. During playback the DVD decoder is instructed which video and audio stream to use plus which subtitle stream to overlay the images.

Thanks for those thoughts, right now as I write my DVDarchitect has been rendering for 40 minutes, butthe percentage bar remains at zero, which I think means it actually is doing nothing Why did this occur?
The CPU usage is 100%

How do you tell how much BUS there is on a PC?

What hardware can one install in a PC that can encode MPG2 & make rendering from Vegas faster?

farss wrote on 1/18/2004, 3:42 AM
Vegas doesn't directly support any hardware mpeg-2 encoders.
The good encoders start at around the $5K mark and go up steeply from there, you really need all the rest of the gear as well to justify that kind of expenditure.
If the percentage bar is still at zero sounds like something has crashed.
What are the brief specs of your current system and what are you trying to encode from?
Joseph69 wrote on 1/18/2004, 4:09 AM
Thanks

Thanks

OK I will give up about the direct MPG2 encoding gear

My PC is P4 2400MHZ Igb Ram Not Book Nvidia graphics
You are right it crashed, I had to restart it
I am going to have to get another PC, a desk top, because I do so musch editing

I think I have given up on FCP & My Mac

Can any one please what components processor, video card etc I need to build my super fast PC

Vegas support suggested dual processor might be a good idea, one does video one does audio, but it seems too complex to me,

Try running the RenderTest.veg Vegas benchmark file, and see how
fast your current system is. You can find the details in this thread:

So far the fastest system I've seen posted used an AMD64 FX51 CPU,
and finished the test in 1 min 24 sec.

My new AMD 64 system completed this test in 1 min 32 sec.

Here's my cost breakdown in Canadian dollars for it:

$ 315 AMD64 3000 CPU
$ 189 ASUS K8V Deluxe motherboard
$ 218 2 x 512 MB Samsung DDR 3200 RAM
$ 179 Antec 1080 AMG Server case w/ Antec True 430 Watt PS ( very quiet )
$ 132 Seagate 120.0GB w/ 8MB cache ( very quiet too )
$ 66 LiteOn 48X CD-RW/16X DVD-ROM Combo
$ 164 Pioneer DVR-106 DVD+/-RW
-------------------------------------------------------------------------------------------------
$ 1,263 Total without tax

My old PC used an AMD XP 2600 on an ASUS A7N8X Deluxe motherboard, and
takes 2 min 34 sec to complete the rendertest .

This new one I just built finishes the same test in 1 min 32 sec, so I'm really happy
with it. Especially since this is the slowest CPU made for this motherboard!
