I have been using vegas to edit wedding videos, the video looks great on my computer but when I put it to DVD it looks like crap, very pixly and just not right, does any one know the best rendering quality to render it as? like wmv, or avi? or is it a problem with the dvd suite 4.0? please let me know!! Thank you very much!!!

You render to MPEG-2 for use in DVD Architect.
The bitrate used depends on the length of the program.

WMV has nothing to do with making DVDs. It's a Microsoft-created video compression technique that makes raw video small enough to be efficiently delivered over the Internet, among other uses.

As mentioned, MPEG2 is the compression format used to create DVDs. I don't use DVD Architect so I don't know the settings specifics, but generally MPEG2 destined for DVD is encoded with a bitrate ranging from about 3Mb/sec up to maybe 8Mb/sec. At the lowest setting the video during action scenes looks terrible; at the highest setting the video should look pretty much identical to the original. You can use the highest setting for up to about 60 minutes of video on a standard DVD blank. More than that, and you need to reduce the average bitrate downwards. Your audio is best encoded as an AC-3 file, which compresses raw audio (about 1.5Mb/sec) down to about .2Mb/sec.

Hope this helps.

1. You MUST render to MPEG-2 if you want to make a DVD. Do NOT render to WMV when making a DVD -- ever.

2. You MUST use one of the "DVD Architect" templates, and should NEVER use the "Default" template (for MPEG-2.

3. You render your audio, using AC-3, and do this as a second step once you have rendered the MPEG-2 (or you can render the audio as the first step -- the order doesn't matter).

4. If your video is longer than 80 minuts, you set the average bitrate using a Bitrate Calculator. Leave the max and min bitrates alone. Don't go above 8,000,000 for average bitrate.
