Is there settings that can increase redering speed?
It takes me 15-20 minutes to render a 1 minute long 640×480 wmv video, or 30-40 minutes to render a 1 minute long 1280×720 wmv video. The videos have 1 audio track, and 1 video track, no effects. I read other posts and believe my sliders havent been moved, and my compositing mode is source alpha. Ive tried playing with bit rates, they reduce file size (which is great) but render speed doesnt change at all. To me, and from what I have heard, my rendering times are 2-3x longer than other peoples.
the only thing that will effect rendering speed I have found is if I render in different resolutions. Even rendering in different formats didnt make any difference.
My comp has 4 G ram, supposedly a lot of free space, and supposedly a good graphics card… Reading other threads people can render videos faster than me with less than this..??
Is there any settings that I can fiddle with that can possibly reduce my rendering times…
Any ideas??

What are your CPU specs?
What are you rendering from?
What are your project settings? Do they reflect your media on your timeline?
What settings have you got for your wmv?
Grazie

My computer is:
dell xps m1330
4G RAM
Intel Dou CPU T7500 2.2 GHz processor
Windows VistaProject settings are
Internet 360 29.97fps
Best
Interpolate fieldsRender
WMV 3mbps
CBR (tried Variables – actually made it longer..)
WMA 9.2
192 kbps 48 hz
smoothness 90
bit rate 1.5
video rendering quality bestI have a hdr xr550 sony handycam – video goes into pmb first, and then into vegas hd 9

I have come to the conclusion that there MUST be either something wrong with my vegas settings, which I have no clue – Ive tried rendering in all the different wmv formats with different qualities and different bit and all are the same speed
However, if I take the same video and render it in Windows Movie Maker it renders in a minute, vs 6-7 minutes in vegas…!!!
Unfortunately, I only was able to test this using a video from a flip camera.
I cannot render my videos directly from my handycam since windows movie maker doesnt accept the original file type they are recorded in!!
converting will do no good, Ive tried this before – loose quality – takes just as long..
At least now I KNOW it is Vegas, and NOT my computer… my computer says it has just about half of its space free (I have no programs other than vegas though, so It should probably be 90% free… hmmm)
So really, any suggestions, if not, any one know of inexpensive programs that accept mt2s files that render 5x faster than vegas like the windows movie maker does… ???

.wmv is a render intensive format for Vegas. If speed is important you might want to try the Sony or MC AVC encoding. Quad core would also help.

Ive already tried all different format types – and I need to use wmv anyways, just trust me on this. It doesnt matter what format I use, it gives me ridiculous rendering times no matter what its not just wmv.
Lets just say then, I wanna render in mp4 (I have tried) – still takes me 30-40 minutes to render 1 minute 720HD clip… 5 minutes elsewhere.
Problem is, I cant render handycam files in moviemaker! 🙁
I dont think it has anything to do with my processor. I DID think it was my computer at first, but as I said movie maker renders 1 minute HD clip in 5 minutes – same clip in vegas 30-40 minutes. and especially when I read other peoples posts say they render in a reasonable times (compared to mine) with weaker comps than mine…
To me its just looking like their is no solution this and ill just be getting rid of this handycam since I cant actually render HD videos I shoot with it. Unless of course by some miracle someone knows what might be wrong.

There may be nothing wrong. Fast renders usually produce inferior quality results. Have you compared the outputs of different solutions?
Have you checked that you didn’t accidentally set the opacity to less than 100%? It’s too easy to bump that control, and its bitten more than a few Vegas users. You can’t really *see* the difference from 99% and 100% opacity, but this will slow the renders more than anything else.

Yeah opacity are all at 100%
I did a test just for the heck of it, and rendered a small 10 second piece with 100% opacity, and then rendered the same piece with 95% opacity, there was really no difference in rendering time. Both took about 2 minutes 30 seconds to render a 640×480 good quality 1.5 bit clip with 1 audio and 1 video track.
Im going to try reinstalling vegas, if that doesnt do anything Im just going to have to put some serious consideration into just selling this camcorder and take a huge loss so that I dont take a complete loss with it, since I cant utilize it in any reasonable manner… Much rather just have one that records in a format that can be imported into windows movie maker, that program rendered videos in 1/10 the time vegas did for the same clip (using my cheap flip camera)

Are you saying you tested rendering a low res Flipvid camera file in movie maker, compared to rendering HD m2ts files in Sony Vegas? You are comparing very low quality apples to very CPU-intensive oranges.
At least so you’re comparing apples to apples, take that flipvid file and put it in Vegas to render out the same thing you did in movie maker. See how long that takes.

I did…
The flip camera shoots in 1280×720 HD and at least 30 fps but I think mine is 60 fps, and I rendered this 1280×720 HD WMV in windows movie maker, and the same settings in vegas and vegas takes 5-6-7- times longer to render.
I tried reinstalling, did nothing.
Thanks for all your help everyone!
I think the best solution for me is to just ditch this handy cam though. A 640×480 10 minute clip shouldn’t take 4-5 hours to render, and the times it takes to render HD are outrageous so no point in having an extravagant HD camcorder then, its ridiculous… lol
