Many Questions VS9

All VS 9 Questions

Is there any reason to use frame base capture if
the final video is for TV viewing (Capture or Rendering)

The top post in the form advises capture compression slider move to 100%
The help file advises this may make the video choppy ( I capture to NTSC DVD)
does this also mean the compression slider is at 100% for Capture, Render, Create DVD ?

Does Variable Bit rate make video choppy why not use Constant? (Capture and Render for DVD)

Should you render with two pass conversion?
if you use constant this option is no available

Finally if your project setting need to be Exact as you Create video file
How do you create a video file with Dolby 256 Audio

If you tell it to match first clip it thinks it is MPEG audio
What I have been doing is Capture to LPCM and then make my video file Dolby 256 audio

NO---use upper or lower????????--lower for digital source.

The top post in the form advises capture compression slider move to 100%
The help file advises this may make the video choppy ( I capture to NTSC DVD)
does this also mean the compression slider is at 100% for Capture, Render, Create DVD ?

I leave the slider at the default setting and get good results--experiment and let us know the results.

Does Variable Bit rate make video choppy why not use Constant? (Capture and Render for DVD)

I use Constant for any setting above 6000 kbps, but variable should be ok.

Should you render with two pass conversion?
if you use constant this option is no available

Two pass is for Variable only.

Finally if your project setting need to be Exact as you Create video file
How do you create a video file with Dolby 256 Audio

Capture to DD, using the custom options you can select DD.
Use the make Movie manager to create your own templates.

If you tell it to match first clip it thinks it is MPEG audio
What I have been doing is Capture to LPCM and then make my video file Dolby 256 audio

If you captured to DD then it would have used DD when matching first clip.

To add to Trevor's excellent comments if you want to change your capture settings to match output to DVD here's how:

1. On the Capture menu set Format: to DVD.

2. Go to Options -> Video and Audio Capture Property Settings and click on the Capture tab.

3. Click on the Advanced button.

4. Under Templates select DVD NTSC (720 x 480).

5. In the Audio group, select Dolby Digital Audio and set Bitrate to 192kbps.

BTW, there are a few caveats to capturing to MPEG. One, you have to have a machine fast enough to handle it, or a good hardware encoder that can handle it. Two MPEG is a lossy codec, which means if you plan on doing a lot of editing and rerendering you'll lose some quality over time.

Finally, there a good article on AVI or MPEG at http://www.digitalfaq.com/dvdguides/cap ... #mpegvsavi.

Hope this helps as well,

Thanks guys lots of things to try this am.

Is there a reason to use 192 I have been using 256



Also I recaptured at D 256 audio and my project still said mpeg audio
and I did make a movie manager with dolby audio ??

Eric

[Eric VS9]

It looks like I can make a video file from movie manager
But with dolby audio there is no way to show it in my Project proerties
just LPCM or Mpeg audio my Installed CODEC are

MPEG-2 Full
Dolby Digital Full

I have read that the project proerties MUST match the video file I want to
create before building my final video
I can't get that to happen

Hi Eric

You are correct in saying that the ‘Project Properties’ do not indicate DD audio.

For some unknown reason VS does not show Digital Dolby as part of the project properties. ( a mistake in the software I assume)

But if you capture to DD or create a template containing DD then the resulting file will have DD.

When you render Share Create Video File use your template or custom settings that can select DD.

To check your video properties—right click a clip in the timeline and select Properties.

Hope this helps

Trevor

[Eric VS9]

Yes that helps I was not sure why the project properties would not show DD
Thank You!

I am still concerned about editing because the project properties do not match the video file ??
will my audio go out of sync.

I am wondering if I should set my project properties to LPCM
then capture with LPCM and edit with LPCM make a final video with LPCM and then convert the Final Final video file from LPCM to Dolby then burn to DVD

[Trevor Andrew]

Hi Eric

Although VS does not allow you to select DD within your project properties.

When you go to Share Create Disc you will be able to view DD as an audio option.
(I am not saying that you should render during create disc)


Try a test:-

Start a new project (important)
Capture to DVD format using DD audio.
Then go directly to Share Create Disc.
Press the cogwheel lower left to select project settings, indicating that DD is selected.

Digital Dolby will be maintained from capture through to burning.

If you need to re-render (Share Create Video File) make sure you select DD as the audio format, either by using the same as first clip the custom option, or your own template.

I cannot see any benefit in using Lpcm audio then changing to DD.

RGuthrie -- although I don't live in NTSC land, I was intrigued as to why you suggested selecting 704 x 480 as the template size, instead of the full 720 x 480...

I have read that the project proerties MUST match the video file I want to create before building my final video
I can't get that to happen

So long as you match the video properties, Smart Render will work. Changing the audio format or bitrate doesn't appear to prevent Smart Render.

Ken,

Thanks for catching my typo! The fingers were working faster than the brain again. I'll fix it, it should be 720x480.

EricVS9,

From my searching and reading around the web 192kbps is fine for DD audio. Dolby Digital when compressed to 192kbps offers a higher quality than other codecs from what I've read and from what I'm hearing. Now I'm sure a sound engineer with "golden ears" would argue that 192 isn't enough... Also, using 192kbps allows more kbps to be used for the video bit rate (or for more video length if your trying to fit more video onto the DVD).

[Eric VS9]

Thanks for the info.

Is that whats happening is there a fight between the video and audio if the audio is to high DD448 or DD256
so by lowering to 192 should help and the DD448 or DD256 may have caused playback problems ???

I will give it a try
Thank You

[rguthrie]

Eric VS9,

Well, there's probably not a fight going on, however, your DVD player may not be able to properly playback Dolby Digital encoded at a high level. I know for example that the PSP (Playstation Portable) has limits as far as what it can handle bitrate wise for both audio and video. Unfortunatelt, I don't know what the "industry standard" is for DVD players as far as audio goes. I do know that for video it's 10,000 kbps. That doesn't mean however that we can encode at 10,000 kbps, it's more complicated than that.

Happy New Year!
