Vegas rendering very slow

Hi,
I have a been using Screenblast and decided to purchase Vegas MovieStudio as well for a second PC. When testing, Vegas takes 4 times as long to render the same movie. This seems to be regardless of format, PC or graphics card as I have installed it alongside Screenblast in different setups to test.

I'm using W2K SP4.

Has anyone come across this problem or know of any fixes?

Many thanks.

this is not an answer but--

I just bot a Toshiba 3.3ghz p4 laptop. last night using vms 4.0 (not"a") i rendered 10 clips about 90 seconds each using NTSC DV Widescreen, captured via VMS from my Panny gs400 taken in Widescreen. they took 17.7 minutes on the Tosh and 26 minutes on my 1.8ghz Athelon desktop. i had some problems with my laptop, so this AM i formatted and reinstalled WinXP SP2 and VMS, DVDA. i burned DVD's from each and they looked the same. the resulting .avi files on the Tosh are the same size as last nights render on the desktop--2.0gb

Rendering the SAME clips in the same format--it is taking 48 minutes..... why the difference?? do i have too much disk space now??? last night, while rendering the Preview screen was blank--(this has happened to me before), but this morning the pix is there as it is rendering. i have these kind of problems on my desktop too using VMS 4.0a.

so-----i know it doesn't fix your problem---but you are not alone with these problems.

Addendum---- one of the reasons i reformatted/reinstalled WinXP SP2 was because when DVDA was burning a DVD+RW it would hang forever at 34% burning the Lead-in. Nero 6 would always burn the DVD just fine. so i thought maybe some file was damaged. Well--after playing around the AM, i have the same problem. A virgin system with VMS & DVDA and it hangs. Back to CircuitCity with this laptop i guess.....

If Nero burns but DVDAS doesn't, then the problem isn't with your laptop, it's with DVDAS. Solution? Don't burn with DVDAS.

There are a number of factors that impact rendering speed - CPU speed being only one of them. Laptops typically have slower disk drives, so even if your laptop has a faster CPU than your desktop, your desktop may render faster simply because the disk drive has faster access speeds. Other things that impact render speeds are effects placed on the timeline, etc., so you need to be careful to compare apples with apples.

What surprises me is that Vegas renders almost 4 times as slow than the previous Screenblast on the same system (fast SCSI drive, Xeon cpu, fast RAM). I've tested this on other set ups too so it looks like a software issue with Vegas (no word from Sony support in 3 weeks of trying).

If this is the case then I'm hoping that an update will be released soon to fix this but maybe there is a work-around someone knows?

How are you setting up your tests? Could there be a systemic problem with the approach? I admit I'm struggling to think of something that would cause that big a difference, but sometimes these things are so glaringly obvious you can't see them!

Very true! I have a couple of same spec PCs and load an identical W2K image on to them, put Screenblst on one, Vegas on the other. Like I said Vegas takes almost 4 times as long to render the same file in a number of formats.

I then installed both programs onto the same high-spec PC and ran them one after the other - same results. If no one else has noticed this problem then maybe Vegas has an issue with one of the components on my PCs (all HP)?

Yes, it probably is something obvious. As ever - any ideas much appreciated!

Are you starting a new project each time? I'm wondering if the defaults for versions 3 & 4 are different? You could create a project in v3, save it, copy the vf file (just in case!) and then open and render the same project in v3 & v4.
