Does more RAM speed up Vegas rendering time?

I have 1gig of ram in my system (dual core 3.0 p4) and I notice the difference when I used to render to my laptop - my new systemn is faster, but not that much faster (my laptop is 1.5 celeron, 512 ram). Is there a chart or a listing somewhere that shows the differences in rendering when adding more RAM? I am thinking up upgrading to 2 gig, but wonder if it is worth it.

More than one gig of RAM is only beneficial to Vegas if you use a lot of graphics/stills/static title cards from your graphic editor. More RAM is often good for other apps, but regarding render times, etc...Vegas doesn't use a lot of RAM for vid.

Is there anything that will speed up rending times then?

knowing more specifics about your workflow and media is key to offering advice about rendering speeds. There are a lot of optimizations that can be achieved on a per-project basis, but as an overall whole, there are no "this will speed renders by XXX%" sort of answers.

If you're using a lot of graphics, then add RAM.
If you're using a lot of HDV, consider how you're allocating those files to the timeline.
If you're using downloaded media with a wide variety of less common codecs, consider converting them prior to using on the timeline.
If you're editing includes using DVD-based or CD-based media, consider transferring that data.

These are just a very few considerations when wanting to decrease render time.

Actually, I found that boosting ram from 1GB to 2GB did improve rendering times.

I was editing an HDV project with some still image montages as well, and I noticed that Vegas was chewing up all the RAM, and hence hitting the virtual memory quite hard (lots of hard disk thrashing).

With 2GB, Vegas used up a lot of RAM, but the amount of paging to virtual was much reduced. Since disk access is a much bigger bottleneck, overall render times were much improved.

dual core...

Although moving to 2 gigs improved my render times also, the biggest jump for me was by going to a dual core processor. I went with the Athlon 64 X2, but since then Intel's released the Core 2 Duo and these blow the doors off all previous processors. I've also noticed a bit faster rendering since I upgraded to Vegas 7 from Vegas 6...Sony has apparently improved the utilization of dual core/multi processors with the new version.
Just my 2 cents.

Well, I went from a Celeron 1.5 to a dual core and I didn't notice that much of a difference in rendering time, unfortunately even with 800FBS on my motherboard. I have 1 gig of RAM right now, and even if it help a little, I would like to upgrade to 2 gig....I just wish RAM wasn't so darn expensive!

David- If you went with anything from the P4 D line (which from post 1 I see you did), I can understand not seeing much difference since that was a quick fix from intel to try to keep the excellent AMD X2 line from running away with the show. Intel basically threw a couple of P4 chips on a die, they didn't design them from the ground up to work well together but they were cheap. (Sort of how in the '70s, GM wanted to market some deisel engines for gas efficiency, but all they did was take a gas engine and modify it. They were crap. ) However, Intel has done it right with the Core2Duo...now AMD is playing catch-up.
As for ram being expensive, I've been in ram heaven since the prices are so low right now. Even ddr2 can be had for less than 100US for a gig (TigerDirect)...I would think that would translate into even less for you in CA, what with the good exchange rates and all.
Just curious, are you running hdd's with good transfer speeds in your desktop?
Keeping the media on a separate drive from the OS/Apps? Defragging often? Saying your prayers at night? I know, all the stuff you probably know already, but just checking on some of the basics...

Yeah, I have the D series, lucky me.
As for RAM, $130.00 Cdn gets me 1GIG of APacer DDR400 ram. Still alot of money when I want to buy audio/lighting equipment for my film-making habit.
As for my CPU, I wonder if I can overclock it or if there is anything to make this thing go faster, alas, I might have to upgrade again and throw the $250.00 down the drain I paid for this processor.

I am a bit discouraged thus far, with Vegas 7. I just went the upgrade route, buying 6 from BH and then upgrading on line. Great deal.

Over the last several months I have been on this board, Vegas seems to be the consensus best in terms of PC editing... However, at least with render times, my Premiere Pro 2 seems to be a lot faster. This was in DV, and I selected best for both renders of identical footage.... Technically, I have no idea if Premiere is providing less in the render, but I haven't seen the advantage yet. Comments please. I am trying to understand if there is a difference in the output between the two.

I am beginning to learn to like the Vegas GUI, but am still concerned that I am losing speed... I have heard that Premiere Pro might be using the video card as well as processor. (I have Dual Core AMD 3800+, 2 gigs mem, and an ATI X700 PCI Express video card with 256 meg.

Don't render "best" in Vegas... it's usually unnecessary and significantly increases render time.

There may be really subtle differences in output. The actual filters you use will make a bigger difference though.

2- David, benchmark your system against the rendertest.veg results that are available. Your system should come in about 44-45 seconds.

Rendertest (the old one with lots of results)

Do the rendertest at BEST quality, not good. The results below are for BEST mode.

Athlon XP: There are results if you look around. They aren't as fast as Pentiums or AMD64.

Platforms that support dual channel can run a few percent slower when running memory single channel. See Glenn Chan's (that's me) benchmarks at
http://www.dvinfo.net/conf/showthrea...threadid=18841
Systems with 2 pairs of identical RAM may also perform slightly faster.

Northwood-core Pentiums are about 6% slower than Prescott-cores (the 5xx series). Northwoods are typically faster at everything else, and consume less electricity.

Overclocked systems are not necessarily stable. As well, they may perform slightly better or worse than a stock system running at the same clock speed. Overclocking on Intel/Pentium platform implies an increase in FSB speed, and an increase or decrease in RAM speed (depends on the RAM they use).

Vegas 6 results may differ from V5 results. see http://www.sonymediasoftware.com/for...239&Replies=57

Well, nothing against Premiere, Final Cut, or xPress, etc. People are doing great work with all these editors. I find that the workflow Vegas supports is very efficient for my work, and, the interface is very understandable. Hopefully, you'll find similar results.

Seconding what Glenn wrote. As I understand it, "good" quality is fine for all renders of standard definition to standard def.

"Best" rendering quality will sometimes improve quality when rescaling, e.g. from HDV on the timeline to standard def for DVD, or from standard def on the timeline to 320x240 for web, etc. But it is worth rendering a short test to see if "best" actually benefits your project, because render times do go up dramatically.
