Rendering time, how long did it took you?

I rendered a 1hr 21min file with very little video fx to mpeg-2 using custom variable bit rate average of 6700 with two-pass and it took me 11 hours!!! It is worth it though since the quality came out really REALLY good -- very close to HD quality, but man...11 hours???
AC-3 5.1 audio took about 20 minutes.

I am using a Toshiba Satellite with Intel Core 2 Duo T8100 @ 2.16 GHZ, 4GB RAM with about 80GB space left on drive.
We'll see how my new Dell XPS (Core i7-2670QM @2.2GHZ, 8GB DDR3) do when it arrive next week.

A LOT depends on your project properties, the format and codec of video you used for your source and how heavy the effects were that you added to your movie.

But, for a hi-def movie on a little dual-core laptop, a long render time isn't surprising.

Well, it's not HD but actually rendered and maximizing the bit rate to mpeg-2 for a DVD, like I said, the quality is very close to HD.

How can the quality be close to HD? HD has over four times the resolution of a DVD.

But, if you're using DV-AVIs as your source footage and outputting DVD-quality video or video for DVD Architect, it shouldn't take you more than twice your video's running time. Less than two hours.

But you may be complicated the process by trying to up the bitrate -- which will slow down your process without improving your picture.

By close to HD I don't mean 1080 but they are pretty close to 720. Basically, I rendered as mpeg-2 from ACVHD sources stored in an external WD 2TB Elements drive. From the template I use NTSC for DVD Architect Widescreen stream, then customized the bit-rate because it was more than 1hr 21min. I did this with two-pass.

Previously, I rendered some files that were less than 45 minutes in length and opted for one of the preset templates (NTSC for DVD Architect Widescreen Stream) because it was less than an hour's time and it only took 1.5hrs to render.

What do you mean by "using DV-AVIs as your source footage"?

You do understand that DVDs are just 720x480 video, right? So by adding 1280x720 video to DVD Architect, you just gave the program more work to do down-rezzing it to 720x480 DVD?

You can't force a DVD to have higher resolution. It's a DVD. 720x480. And the closer the video is to that you give DVD Architect to work with, the faster, cleaner and more efficient your transcoding will go.

Steve I understand, but the video I rendered was in 720x480, not 1280x720, with that said it came out pretty darn good and close to 720HD even though it is rendered to put in to standard DVD format, and this was coming out of my 42" 1080P Panasonic Plasma; an HDTV big enough to show every kind of flaw should there bare any.

I read somewhere that Vegas doesn't do well (in rendering times) with 64-bit OS Systems, perhaps this is my problem since I am using W7 64-bit? Some say VMS is only compatible with 32-bit systems.
