do I need to render this long?

Hi,

I'm currently doing a 1.5 hour video. I edited it in Vegas 6 and render as an MPEG2. I then opened it in DVD Architect after I made the menu, and it renders AGAIN in the DVD program.

Is this necessary to do? Do I need to have it render twice?

It took over 2 hours in Vegas, and it's looking like even longer in Architect.

Can I bring it into Architect w/o rendering it as an MPEG 2?

Or, can I get away with not rendering inArchitect?

Your help is much appreciated, as usual!

Thanks.

Yes, you can do your Mpeg2 render in DVDA, but you don't have as much control over the settings.

The real question here is if what you are seeing is a re-render of the video or if it's other assets such as the audio.

You can check by going to File> Optomize DVD and anything with a green checkmark will not be re-rendered.

You do not need to render twice. Check to see how big your rendered mpeg2 is. If your DVDA project is over 4.7 gigs, then you probably rendered the mpeg2 at too high of a bitrate, and then DVDA would have to re-render it to fit on the disk. For an hour and a half project, render as a mpeg2 DVD Architect NTSC Video stream. That puts the bitrate at 6mb/s. For an hour and a half video, this leaves room for a decent sized menu and DVDA won't have to recompress.
You could also render an .avi file from vegas and bring that into DVDA but it would have to render the .avi.
-Also, check your audio settings in DVDA. PCM audio takes up alot more space than AC3 audio.

If it wasn't DVD compliant from the render done in Vegas, DVD Architect will re-render the stream. You definitely DON'T want to render twice, as re-rendering MPEG dramatically weakens the image.
You can bring it into Architect without rendering to MPEG 2, but then you're still rendering to avi first, and that's a long render process too.

So...
Consult a bitrate calculator before rendering to MPEG2 to be sure that your video will fit on DVD. If you're at 90 mins, you may well have encoded at too high a bitrate to fit on the DVD depending on audio and menu content.
After determining the bitrate for your vid, render in Vegas. If you do this often, you may want to create a new template just for this length of video and DVD burning.
Be sure to use AC3 audio on projects longer than 1 hour.
Use either the Batch encoder in Vegas to render both audio and video so that they are the same filename/same location, or use the DVDPrep tool to prepare the render.
Then DVD Architect will see everything as clean and clear, and you'll have no second render.

hmmm.... looks like that's the problem... too big for a DVD. I also saw the "fit to disc" in Architect, but not totally sure how to figure out what size bitrate in Vegas.
This helped me lots, anyway.
Thanks

Hi jimingo,
Thanks for the setting tip!

Actually, this setting says video only...

Right, it is video only, you have to render the audio seperately. Render the audio to the default AC3 settings.

Another option is to use DSE's dvd prep tool to render both at the same time, although I'm not sure if you can adjust the bitrate on the video.

Here's a bitrate calculator that will tell you what average bitrate to set (use the Custom setting when encoding the MPEG-2 video). Leave the min and max bitrates set to the default. Use one of the "DVD Architect" templates as the starting point.
