Top render settings for audio to burn to bluray?

[Steve Rhoden]

What kind of blu-ray you want to burn?
Is it the regular video and audio content created in DVD Architect,
for playback in a typical blu-ray player?
If its the latter, you need not look further than using the already
built in DVD Architect Templates.

Yes for a typical bluray player. It’s not a blockbuster feature, but an independent film.

I’ve used AC3 in the past, but I have rendered multiple wav an aiff (because someone wants the files for a mac at some point).

What would you suggest for a 1080p independent film? I’d like the best quality without chocking a home bluray player, if that’s even possible.

You can burn up to 24-bit/192kHz PCM on Blu-ray. Of course, that’s not an issue if you have 16-bit/48kHz sources. Any old Blu-ray player will dump that full resolution audio out to an HDMI output, but you’re unlikely to find many audio devices that can really deal with 192kHz sampling or a real 24-bit output that doesn’t include “marketing” bits.

Of course, some folks use an optical output, same as they did for DVD, which means that anything you put on your Blu-ray will get schlepped over to the receiver or TV as 16/48k stero, if you’re stereo, or 5.1 AC-3 at 448kb/s or you’re mulit-channel. That’s just dealing with the limits on Sony/Philips optical or S/PDIF wired digital audio. But you’re also hopefully not authoring for the worst that can happen (and this is close, given that so many Blu-ray players only have digital outs these days).

On the other hand, if you are recording in 24-bit, and in particular, if your resulting audio is the product of a mix of multiple sources, you may very well have a real 24-bit resolution on your hands. Less likely in video than multi-track audio recording (which I also do), but just keep in mind, each simultaneous new source adds more more bit of real dynamic range to the final mix, at least in theory (before any compression or limiting).

And the more practical approach applies too… if I have a video that’s not using the whole BD, and I have 24-bit audio (at 48k, 96k, or 192k), why NOT include that in the final project.

Well, i guess David handled this for me extensively, lol.

I do music things… the audio capabilities are often more important than the video. Or at least the potential… it’s likely most listeners aren’t going to have systems that fully exploit CD, much less full-on Blu-ray audio. But some do… Neil Young didn’t start doing his “archives” until Blu-ray came along, as he was waiting for a format that sounded as good as his studio recorders.

But even from where I sit.. everything I record in the field, whether video or video + audio is nominally at 24/48k or 24/96k these days. If I do a recording session, you might notice that I can’t afford a dozen Neumann mics, but the recording quality is going to be way up there. Good times we live in! And if you’re just doing stereo, the audio part at full 24/96k isn’t even all THAT big.

Blu-ray also offers a slew of higher quality compressed format. Two problems with that. The most practical is that DVD Architect doesn’t support any of that… DVDA’s goal is pretty much to let you make a BD that’s very DVD-like, but using some of the BD media types. None of the higher-end BD features, and that suits me fine most of the time, since that way, I’m not compelled to waste time using them. But the other thing about the higher-end audio parts… some BD players don’t decode these, some receivers don’t either… like DTS back in the DVD days. So you have to also include a second compressed track in standard 192kb/s or 448kb/s AC3, if you want to be certain everyone can play them. So I haven’t found this a huge issue for DVDA, because I’m not certain I’d use those features very often.

Sounds like my “safe” audio is 16 bit 48 audio, using my standard stereo.
