Can I export just the video?

[John Rofrano]

This is what you should always be doing for final renders (i.e., rendering video and audio separate). Select any of the MPEG2 DVD Architect templates and you’ll see that they are video only. Then you export your audio as Digital Dolby AC3 using the same filename (with an AC3 extensions of course) and DVD Architect will join the two back together when you import them.

To turn any rendering template into video only, just click the Custom… button and go to the Audio tab and uncheck the Include Audio Stream check box.

Hi John
Splitting the video and audio, does this have any effect on the rendering speeds?
thanks in advance

[Ian Allenby]

along the same lines, can anyone explain why I don’t just keep the ‘include audio’ ticked? Why does every experienced user seem to want to render the audio and video separately? Isn’t that two operations and two files when one will do?

[John Rofrano]

I assume the rendering speed is the same just split over two renders. Rendering the audio alone is usually very quick.

Sure. The reason is because MPEG2 Audio is not “legal” on Blu-ray disc or NTSC DVD’s. The only allowable audio is PCM (wave) or AC3. If you render your audio to MPEG2, DVD Architect will re-render it to AC3 loosing quality. You want your AC3 audio rendered from the original source for the highest quality possible or render your audio to PCM Wave for even higher quality if you have the space.

For PAL DVD’s MPEG2 is actually a legal audio format. You don’t have to split your render if you don’t need 5.1 surround for PAL DVD but for PAL Blu-ray you do.

Hi, John–

Sorry for the n00bness. Can you step my through this? All I see is Burn to Blu-Ray under Tools. Where do I go exactly to do the export?

As well, is MPEG 2 the highest quality for 1080p material for output to Blu-ray, or is there something better I should use, and sorry, what are the optimal settings for Blu-ray output?

Thanks again 🙂

Sure. Since you said that your video as 1920×1080 I’m going to assume it is not HDV (which is 1440×1080) and is actually AVCHD. If that is the case here are the steps:

To render the video:

• From the Vegas menu select File | Render As…
• In the Render As dialog under Save as type: select Sony AVC (*.mp4;*.m2ts;*.avc)
• Under Template: select Blu-ray 1920×1080-60i, 16 Mbps video stream
• Click the Save button

To render the audio:

• Select File | Render As…
• In the Render As dialog under Save as type: select Dolby Digital AC-3 Pro (*.ac3)
• Under Template: select Stereo DVD or 5.1 Surround DVD depending on your project’s audio
• Click the Save button

Name both files with the same filename just with the different extensions (*.avc and *.ac3). That should do it. Each one will render when you press the Save button.

Hi, John–

This looks great. Thank you 🙂

Can I just ask you, what app you use to put the two files together and burn (or preferably, create a blu-ray image, or BDMV folder I can burn several copies from later on)? Is that DVD Architect, or do you prefer Nero or such?

Best,
Jeffrey

EDITED: Sorry, I forgot to mention, of course, you’re right, it is in fact AVCHD material.

[Ian Allenby]

John, Thanks for the explanation re audio. As I am in PAL world, this explains why it didn’t seem to be an issue. Now I know, I will have to experiment with audio quality to see if I (or my clients) will notice a difference
Thanks again.

I use DVD Architect 5.0.

I wouldn’t allow Nero on one of my systems since version 8 which totally disabled my ability to work with DV AVI’s in Boris RED because it insisted on inserting it’s own inferior filters into the DirectX filter chain which affected all NLE software on my PC. IMHO, Nero is intrusive bloatware that you don’t need. I use the free ImgBurn to burn CD’s which is all I need Nero for but it no longer does without bringing along all it’s unneeded baggage. (…get the feeling I hate Nero?) lol.
