Unless you're playing with some settings, ergo, telling it to render at 41Khz, Vegas auto-resamples all audio for video at the 48K rate. You need to do nothing.

I'm not telling it to render in 41, all the audio I have in the project is 41. I need to know how I can render this project as a DVD (MPEG2 audio 48khz) without it sounding slow. Is there a setting in Vegas that we are missing that will resample the audio without it changing the rate?

When you render the project, if you use the default AC3 template, it will resample to 48 just fine. I'm assuming you're using PCM files for the audio, right? If not, go to Options/Prefs/Audio/ and be sure that Import Audio at Project Tempo isn't checked.

The project was alreay in 48khz and we imported a 41khz wav file. That wav file is not playing at the right pitch until we pitch up the rate (with the scrub control) from 1.00 to 1.09. If we render this file will it render at the rate we set it (with the scrub control).

I also looked for options/prefs/audio (import audio at project tempo) and it's not there. I'm using Vegas 5, did they remove that option in this version?

Thanks again for all the help much appreciated

Send me 20 seconds or so, lemme see what's up with the file.
Read my earlier post, I pointed to exactly where the check box is.
If you don't see it, you're not using Vegas 5b. Download the update.

OK... we have downloaded 5b, and see the project tempo check box. But what is this going to do for our dilemma now? We're still sitting on a 15 minute short film that is completed, and has edited footage playing over a soundtrack that unfortunately has been imported at 44.1, and we are trying to render it to DVD NTSC (is there a way to change these default settings,i.e. -like the 480X480 - 44.1 svcd setting?) but we want it 720X480 and at 44.1 audio. if not then what do we do? And by the way, both audio & video sound and look slow. We are in a huge stumbling block here.
Much thanks again.

You WANT it at 44.1 audio? then you're gonna have problems. Can't be printed to anything w/44.1 audio. DV is 48K. You are changing sample rates in the project properties?
You can change everything from aspect to display ratios in the Project properties, but if you're going to DVD with this, you generally need 720 x 480, 48K audio. The sample rate of the media doesn't matter at all on import. Vegas will upsample/downsample to the audio rate specified in the render setting.
Seems to me you're overthinking what is very, very simple.
I assume you brought in audio from a CD, or what someone recorded as CD quality audio? Vegas will auto-upsample this unless you tell it not to.

Well, we really dont want it at 44.1 and we both know (my partner and I) that DVD is supposed to be in 48k, and if it upsampled why after it has been rendered and we burn it to DVD - the audio and video has slowed down, so know what do we do?

Well...I did invite you to mail me part of a file. Without it, it's a crap shoot at best. I don't know what you're doing wrong, or what is happening with Vegas. Why not open a new, blank project, try copy/pasting everything on the timeline of this project to the new one.
Does it sound right on playback BEFORE rendering? If so, it's definitely something you're doing incorrectly in the render settings. If not, how did you edit the project together with the audio slow?
minna415 wrote on 11/21/2004, 11:17 PM
yes the project, sounds fine before rendering, and we already tried opening up another blank project this time with the opening audio setting set at 48k and imported the massive audio soundtrack file - but it still came up in its properties as 44k, so we figured that doesnt work. but can give it another try. so yes everything works great be fore rendering, and then after we pick 720X480 DVD NTSC the finshed version comes out sounding and looking slow. thats it in a nutshell, if anymore advice let us know. and how can we send you a snippet?
Thanks again

Sorry to butt in here!
Firstly SPOT did give his email address in a post above.
When you import media, vid or audio the clips properties aren't changed, I assume you're checking that by right clicking the media on the TL?
What matters is the Project properties. If the project is 16/48K then all audio will be previewed at 16/48K. When you go to render out then the default for the render will match the Project properties, but you can change this during the render.
Like SPOT said, I think you're thinking about this too much, I've mixed audio at 16/32K, 24/48 and 16/48 all on the one T/L and rendred to 16/48K for DVD and it all comes out just fine.
Actually I'm having a hard time trying to figure out how you CAN make it go wrong, I'd guess if you went into the media properites and changed them then you could screw things up as Vegas would assume the audio that was actually 44.1 was 48 and NOT do a rate conversion, maybe that's what you've got wrong. Even that doesn't quite make sense to me as I'd thought if you get the sample rate wrong then pitch / speed were the least of your worries, you should be getting nasty clicks in the audio.
Perhaps one thing to try is just render out a small section as NTSC DV, 16/48K audio and play that back, see if that sounds OK. This is much the same as what Vegas serves to the mpeg-2 encoder.
Bob.

Thanks guys for the help -
Seems like something is not right with my partners software, because sure enough, when I came back to my house and pulled up the project, the project properties options are different, even allowing the "Custom Button" to work which did not for some reason on his computer. And I tried what you Bob said to do - which was try rendering a small section and have experienced no problems with slowing down, any last tips on how to make this project which was shot with a hand held Sony DV to look non-pixelated when blown up to the 720X480 DVD size, what should some of the settings be best on?
Thanks again for the advice, you guys are life-savers.
