Render times? Is it too long?

I am rendering a 1 1/2 hour clip. I have a reduce interlace flicker script running and video supersample set a 7 for the length of the clip. My machine has an AMD athlon xp2200 w/ 1 gig ddr. and two 40 gig drives.

My question is this...Is it out of the ordinary for the render time to be about 40-50 hours? I cancelled the render after 10 hours w/ only 10% being rendered. I have no other applications running in the background or system tray.

I was just wondering if this was normal...

Thanks

Do you have the effects running for the entire length of the video?? If so then it is definatley possible to have that long of a render time. IF you only have the effects in the beginning of the video then vegas sometimes gets "tricked" into thinking the whole video will be like that and gives you an initial render time of 40 hours, but when it get's past the part with the effect is will signifigantly drop down.

The effects I described run for the length of the video.

Supersample in particular will slow down renders greatly. Setting it for 7 effectively means that Vegas has to generate 7 frames for each frame of output.

So in essence, forgetting about all other effects.. It will take 7 times longer then normal.
I just wanted to ask, wanted to make sure vegas wasn't acting up...

Well, not necessarily 7 times as long. The added time is only for the track/event that is being supersampled, and Vegas may or may not have to do as much work for all additional 6 frames as for the final frame (some effects may be applied after the final frame is generated) ... but it will definately add time.

Well, i had to drop the idea of supersampling. After 20 hours of render. It was only 15% done. I cannot wait a full week to finish this. I have a fairly fast machine, maybe I just added too many effects.

Just for reference: A very effects intensive 15 second clip using large size still images took about 90 minutes on my P41.6 1GB DDR ram system. When I added motion blur and supersampling, the render time jumped to 22 hours.
