Rendering WMV9 - sooo slooow

I'm on a 3ghz P4 w/ 1GB RAM. I'm rendering a 4 minute video clip in WMV9 to show a client in a remote location. Is there any good reason that it takes almost 3 hours to do this render? I set it to 512kb/sec, NTSC preset, but then made it progressive, (de-interlaced and de-noised in the pre-compression stage)

Does the de-interlace and denoiser take that much more time for you guys?
The project is mostly stills, a few video clips DV AVI's at 16x9.

I export from premiere and then use the windows media encoder to make the WMV files. rendering does take some time. be glad though i had a 5 minute clip take 13 hours...ah but i liked the result.
 
You could export it as uncompressed. Then use windows movie maker if you are just looking for something quick. That should only take 5-10 minutes on a 4 minute clip.

If you are looking for more quality then look into Sorenson Squeeze. Great program and lets you alter just about any setting of any codec.
 
There are a lot of variables that effect quality and render time, obviously the higher the quality the longer the render. You need to experiment to see what provides the best quality for the amount of render time. I'm not sure how noticable pre-compressing de-noise is for example.

I have a 25 minute HD sequence with a mix of panning and scanning stills and liva action which is approximately 9GB's that I compressed to a little over 800MB's with WM9HD and it took about 2 hours [and looked remarkable].

Sorry I can't be more specific but the best I can suggest is to take a 30 second clip and experiement with the different settings. You shouldn't have to pre-compose to render a progressive frame, so maybe you have some redundant steps in your workflow.

When I first started using WM9 I thought it sucked, but then when you think about how good the image quality is for the amount of compression it is doing it's pretty amazing. Also something I found odd about it is that when I take the same HD file and encode it to 720x480 it takes the same amount of time. I expected it to be quicker.

So bassically I don't really know what I'm doing and I rambled for nothing. Just experiment...:)
 
This is themost efficient way of exporting for Premiere 6.5:
(I'm sure it's the same and in the new version)

- Export the video with exactly the same settings as your project settings.

- Never export another file format like wmv or mov except from avi (and best case with no codec), as Premiere does a double job rendering to avi and then apllying the format.
 
It's amazing, I did another render this morning, same file, but turned off a bunch of stuff- made it single pass CBR, WMV9, 96kbps audio and it took like 8 minutes. Plus the file came out smaller. Crazy.

There's just so many options for export, it's mind numbing.
 
Part of deciding the bit rate is what your going to use the content for. I'm using it to play HDDVD's on a 42" plasma. The highest bit rate the player can handle is approximately 8Mb's.

If you want that level of bit rate and you want the HD content to look awsome then you need to use a 2 pass process which like you've discoverd adds to the render time.
