Rendering video to DVD?

cervama wrote on 2/2/2004, 8:33 AM
Hello, I just finished a family video, I want to know how do I render the video so I can put it on DVD using DVDA? I understand that dvd uses mpeg2. So do I render in vegas as .avi or Mpeg2? I don't want the sound to be
re-compressed since it's has mp3, and .wav on the audio track. How do I do this to get the best quality on the dvd? video and audio? Thanks in advance

Just render as "MPEG-2 DVD Architect template" (Choose NTSC/PAL/Widescreen or not depending on what your footage is) for the video. Depends how long your movies are as to whether you are going to have to lower bitrates to fit it on disc. What's your total length of movies (& motion menus together ?)

As for compressed audio
DVD Architect is going to convert your .mp3 audio anyway it won't ouput that.
WAV is going to eat up lots of valueable space & unless it's a video of a concert or something I'd doubt you'd notice any drop in quality with comppressed ac3 audio anyway.

Do a 2nd render this time for the audio as AC3 audio & save the audio file to the same directory as the video with the same filename (ie myvideo.mpg & myvideo.ac3 saved in the same folder). then when you import the video file DVD architect should use your ac3 audio with it.

so I render the video and audio in vegas to mpeg2? seperately? save on same directory? open in dvda, both files then render in dvda. How does dvda know how to put both files together synchonized? can you explain, I'm new to this. thanks

by the way it's 40 minutes long

40 mins - you won't need to lower bitrates from template with that amount you will be fine.

Yes do one render of MPEG-2 using one of the DVD Architect templates (this will provide your video file)
Then do another render this time an AC3 one (for the audio)
Use the same filename for both files (file extensions will be the only difference .mpg for the video & .ac3 for the audio) & save them to the same directory.

In DVD Architect got to "Options>"Preferences>General tab" & ensure that there is a tick in the box "Automatically link similar audio & video files". Then when you load your video file to the project DVD-A will automatically link & load your matching audio file.

vonhosen is correct: you do two renders. The first render is MPEG2, using the DVD Architect template (NTSC or PAL). This template renders video, WITHOUT any audio. When this render is finished, you render exactly the same video (if you are rendering a loop region), but this time choose AC-3 audio, using the stereo template. Give this audio render the exact same name as the video render. When you run DVD Architect, and insert the MPEG2 video, DVD Architect will automatically look in the same directory (folder) for an AC3 file that has the same name as the video. If you don't get the name exactly the same, your video won't have any audio. However, all you have to do is double-click on your video in DVD Architect, and then on the right side of the screen you will see a place where you can specify the audio. You can either drag the audio file from the explorer window at the bottom of DVD Architect, to the file window in the upper right corner, or you can instead just click on the folder icon and specify the audio file that way.

Thus, setting the file name of the audio file to the exact same name as the video will save you a few steps in DVD Architect, but it is not an absolute requirement that the name be the same.

You can use a batch script to do the two renders in one operation -- a real timesaver. Check the Sundance site for batch scripts. I use the Batch GUI script (which someone else wrote, but which I modified slightly). You can get it here:

thanks a lot, that is as clearer as it get's . I will try that thanks a million

What Happens if you render both at the same time?

johnmeyer, what happens if you render at the same time?

"What Happens if you render both at the same time?"

From Vegas you can't render both at the same time (other than running the script that John was talking about earlier). If you were however to render a multiplexed MPEG-2 file (from a template other than the DVD Architect one) when you imported this muxed file to DVD Architect it would transcode the audio to AC3 or WAV anyway.

thanx, vonhosen...

You can open two instances of Vegas (just double-click on the Vegas icon to start up a second instance, once one copy of Vegas is already running). You can then open the same project in both instances, and render the video in one and the audio in the other. This will get the job done a little faster than using the script, although since the audio is rendered rather quickly compared to the video, the time gain isn't much. However, this trick really pays off if you have two MPEG files to render. You can do both at the same time and be finished sooner than if you rendered one right after the other.

do you know why, if you save the file under another name when you try to open again it says it can't find the file? What I have to then is ignore missing file and it opens.
