Extremely long render!

Hello,

I have a 90 minute project that has been rendering for 7 hours and is only 17% done! I have not added a lot of effects in the video (about 1 minute worth total). Why on earth is it going to take my 3.0 GHz Hyper Threaded P4 35 Hrs to render this video!

If I take the same video and place it into another project it zips through it very quickly. The only thing I have added to the original is 1 3D track motion (at the very end of the video) and a mask effect at 1 spot in my project. I have also added some chapter markers.

Thanks,

Steve

It's the 3D track motion that's slowing it down. The mere act of turning a track into 3d (even if you don't move anything) will slow things down a lot.

If possible, it's best to do your 3d sections as a separate project, render those to an avi, and join them up in another project.

wow, that is crazy. haha. Good to know.
Seems like Vegas should just render normal until it GETS to those 3D things at the end of his video..doesnt it?? haha.

I deleted the track motion and audio (the only thing left is the video track) and it still is this slow!

There is some sort of bug here, I just cant figure it out yet!

Do people from Sony read these forums?

What format are you trying to render to?
(i'll assume MPEG-2 since you mentioned chapter points)

What format is your source footage?

Do you get a box that pops up that says "Over 80% of the selected region needs to be rendered" when you start your render?
(if so check your video opacity sliders to make sure they are at 100%)

I am rendering AVI to MPEG-2 (VBR encodeing, single pass)

No, I don't get any box that pops up, it just tells me the elapsed time and how much is left.

The crazy thing is that when I start a new project and add the same video (uneditied) vegas zips through the render. Is it possible that a corrupted file could do this?

Hmmmm.....I'm stumped!

I know on my machine which is a P4 2.4 it takes about 1.5X to render to MPEG-2 from just a straight AVI file, which should only take around 3 hours or so to do a 90 min program.

Have you by any chance managed to bump the transparency settings for your video track? That could slow things down...

I ask only because a few people have mentioned that they've been able to do this by accident...

The transparency setting is not adjusted.

The only thing I can think of that may be causing this problem is that Vegas crashed when I was working on the project. I used the auto save file and maybe something got corrupted??

I am going to redo the video project and check how fast it renders periodically. This is very frustrating! I am going to contact Sony when I get home from work and see what they think.

I have lost some confidence with this software after this. If this project was a major undertaking (luckily it wasn’t) It would take weeks to render (on a P4 3.0GHz with HT)!

When you say you deleted the track motion, did you also put the track back into 2D mode? If you leave it in 3D mode it will still take forever to render, even if you don't do any track motion.

I completely deleted the track. The only thing left in the project was 1 video track with no track motion effect.

It was my mistake!

I had 3D track motion turned on 2 video tracks!

Thanks for the help everyone.
