You can render WAV files with something higher than 48Khz.
Dolby Digital AC-3 is probably limited to 48Khz.

24/96 audio is kinda counter productive in any heavily compressed audio format like AAC/MP3/Dolby digital. That is probably why they do not let you choose such things.

The "Blu-ray" templates do not output any sound. Sound is disabled because they expect you to render sound separately and the Blu-ray burner will combine the video and possibly multiple audio imports.

My goal is to have a pcm audio track. I assume an audio wav file translates into a pcm file for video?

I was able to burn a BD directly in Vegas at 24/96; under Tools, Burn disc, Blu-ray Disc, Audio template. I then selected the drop down of 24b 96k pcm. So I don't think it's my drivers that's not allowing the higher quantization (when I actually go to render). So I tried the Tools option and that worked, but I'd like to have a menu so the disc doesn't instantly start when it's inserted into the player (cuts off the first few seconds of the song)

The project is only 35min so it's sort of a waste to burn a bd vs a dvd (ultimately I wanted to use Roxio and make a music dvd, or dvd-v, but seems Roxio only allows 16/48 for music dvd).

Still don't understand why I can select 24/96 under Tools, yet not when I go to render under MPEG-2. I know you said BD template don't render any sound, but under Customize Options you can select audio to be rendered with the video, just only at a max of 48k from what I've seen.

In my Vegas install any of the Mainconcept mpeg-2 "render as" templates that begin with the Blu-ray name have audio disabled and do not allow me to re-enable it. This because the Sony Blu-ray burning software, DVDA, does not want the audio taken from the video file but as a separate file. Also, the only audio option is mpeg layer 1/2, which is a lossy format. Not something you want with 24/96 audio.

You can see in the tools menu Burn disc option that they are listing the same templates from render as, and they are rendering a WAV file for burning to disc.

"When I choose my render template, Customize Options, Audio, the highest sample rate dropdown is 48K."

You should be rendering separate video and audio files using WAV (PCM) by selecting File / Render As / WAV (Microsoft) (*.wav). Your audio should not be included in the Mainconcept MPEG-2 render for DVD or Blu-ray. In DVD Architect, the project should be set up for PCM audio.


"I'd like to have a menu so the disc doesn't instantly start when it's inserted into the player (cuts off the first few seconds of the song)."

You can delay the start of a single title DVD by sliding the media down the Vegas Pro timeline a few seconds.

Making a DVD-Video disk in DVD Architect, it will accept 24/96 PCM audio and pass it through without re-encoding. I'm watching one that I made now.

Big Note: 24/96 audio is 4.6 Mbps. That leaves you < 5Mbps for video. Stills or titles are OK. Running water won't look so good.


"...under Customize Options you can select audio to be rendered with the video, just only at a max of 48k from what I've seen."

You don't want to do that! Render separate elementary streams and combine in DVD Architect or with a muxing program.

This procedure will not produce a DVD-Audio disk, it produces a DVD-Video disk with high bit-rate, high bit depth audio.

Ahh, didn't realize rendering the audio separately produces a DVD-Video disc. I thought it made a DVD-Audio disc.

Since the main priority of this disc is the audio, I only have a still picture as the "video" so I should be ok there.

Thanks for all the help. I'll try rendering separately.

OK, I rendered the video and audio separately. But when I go into the Preview mode in DVD-A I can hear the audio track. I re-rendered the project muting the audio track on the timeline (in Vegas) and it still appears in DVD-A

Another strange thing is when I went to drop the separately rendered audio track into DVD-A, it wants to take up two tracks (as if it has audio & video attached). I had to create another track in DVDA, drop the audio track on a lower track and the delete the unused track.

(while in DVD-A) I assumed I could just delete the audio track that was rendered with the project and just insert the new separately rendered audio?

If you have rendered both the audio and the video with common file names (e.g., myvideo.ac3 and myvideo.m2v), bringing the video into DVDA will bring in both files (audio and video). If the names are different, then only the one you specified will be brought in.

Ha, yes, I did render with common names. So that explains why I hear audio then.

So by naming the two files with similar names, when you bring in the video in DVD-A, it will choose the separately rendered audio automatically? meaning I won't have to manually drop the new audio in?

Correct.

"I re-rendered the project muting the audio track on the timeline (in Vegas) and it still appears in DVD-A."

Rather than muting the track, when you render the video, you should make sure that "Include Audio Stream" is unchecked on the Audio tab of the render template.
