Slow Render of 2 hour video
I am rendering a talent show video of 2 hours. It has been rendering for 9 hours and is only 14%.
The only special effects are a 45 second opening and the scrolling credits at the end.
P4, 2.8ghz, 1gb ram, Vegas 5.0d, ram preview is 64mb (can be a max of 895), render quality is set to good. Any Ideas? -

Not without seeing the VEG file. Well, maybe one: Did you use a 3D track? If yes, you may want to render out the small section that uses it separately and then remove the 3D from the main project. Otherwise, post the VEG file so we can take a look at it to figure out why.

How do I add the veg file?

Also check and make sure you didn’t drop set the opacity/transparency by accident. If you set a large section below 100% it will slow it down alot too.

Opacity is ok. What is strange is that I rendered the video first as as AVI after using Excalibur’s multi-cam wizard and it only took about 3 hours. I then proceeded to edit the AVI down, due to total length. Added a 15 second, not 45 as stated in my original post, to the beginning and scrolling credits at the end. I then proceeded to render as MPEG-2 and left it all night beginning at 11pm and at 7pm it was only 11% or at about the 20 minute mark. I have not changed anything. This is so puzzling. I have been using VEGAS since 2.0 and have never had this problem.

Ok, it looks like I discovered my problem. I had two tracks, my main track and a title track that were set for 3D source alpha. I did not need that so I changed back to source alpha and now its rendering about 7000 frames in 5 minutes. It looks like that was the problem. I had been testing some 3D text for the video and forgot about the setting.
Thanks for the response.

Yeah, 3D over an entire project – even if it isn’t affecting ANYTHING – will slow things down tremendously. Glad to hear things got sped back up.
