No 48 KHz audio with ATI All-in-Wonder 7500?

[hurricane51]

When I capture high-quality MPEG2 (DVD) video with my ATI All-in-Wonder Radeon 7500, the only audio sampling rate offered is 44100 Hz. My DVD editors and authoring tools are looking for 48000. Did ATI blow it? Isn't DVD standarad audio generally 48 KHz?

I am not quite sure but from all the DVD rips I tried, the audio is always 48KHz. I have never seen one with 44.1 Khz audio. Maybe that's DVD standard.

The DVD Standard is 48khz. The problem is not your ATI card. I assume your audio card supports 48khz. Microsoft had a silent upgrade to support 48Khz. When I installed Ulead's Media Studio Pro V6.5 it upgraded the Windows Media Player and I had 48khz. I don't know specifically what the upgrade was but maybe someone can point you to it. I had no luck finding it outside of the Ulead update.

Hmmm...I just upgraded my Media Studio to Ver 6.5, but the ATI capture option is still limited to 44.1 KHz. Maybe if I remove then reinstall the ATI Multimedia Center it will fix the problem.

Of course, if ATI ever actually responded to a technical question via email, they might be able to help. However, all I ever get is an endless stream of messages suggesting that I re-read the FAQs on ATI's site.

you can not force ATI to capture 48khz -- if you set it in a profile (force it in the registry) MMC will delete that profile -- I know it makes no sense but thats the way it works

ATI MMC 7.x versions offer a dvd profile but they have it set to 44.1 ... go figure since no DVD can be authored with 44.1 -- welcome to "ATI Logic"

You might have luck capturing to 48khz via software other than MMC

[hurricane51]

Figures.

I was concerned when I saw this post and did a little checking.

I have a Radeon VE (no capture) on this box but an all-in-wonder Radeon on another system and it too has an audio capture upper limit of 44,000.

I have been thinking about a Winnov board (Videum 1000 Plus) to replace the AIW for capture but it too has a ceiling of 44,000.

My Pinnacle 500 Plus does not have this limit.

Is this a poor tech/design choice or some nefarious RIAA or MPAA deal, ya think?

What other Capture cards out there have the preferred 48,00 audio ability?

I had to dig a bit to get the info out of ATI. It is not well publicized that audio has the ceiling.

It's a software limitation of ATI MMC.

[Lamont Cranston]

As I said in in a prior post I capture at 48KHz but I just have the driver installed NO MMC. IMHO MMC any Version is pitiful and is what is limiting your frequency response.

You can do a batch convert from Ulead Movie Factory to change the audio but that is a very slowww process

It is a very fast process if you use Mpeg2vcr. It takes about 90 seconds to convert an 800 meg file from 44 to 48.

[zob]

The Mpeg2vcr program is free to download but in order to activate it you need a product serial number. From what I could tell it cost $249.00 to register the software. Am I looking at something wrong? That cost more than the ATI video card.

[kinneera]

No ATI cards (that I'm aware of) have onboard audio processing, meaning that your system's soundcard actually handles audio processing. Thus, whether you can capture 48Khz is going to be a limitation either of your soundcard or the capture software. If you're willing to consider capturing to AVI, VirtualDub can capture 48Khz audio.

They've had a lot of feedback on that (including some from myself, asking why 48kHz is not an option in MMC 7.6 and lower, nor is it reg tweakable). The "capture and burn to DVD" crowd will be quite pleased.

some of us can't wait until 2004 though....

you can always go the long way for captures already done, without nice programs like mpeg2vcr. re-encode the audio part via tmpg and remux it, or for better quality demux/decode/cool edit to change sampling rate/ re-encode/remux

[Sulik]

From what I understand it should be out within a month or two.
There are always alternatives DVD-it and other software allow you to convert 44.1 to 48kHz without reencoding the video.

2004? 17 months? They'll probably be up to MMC 9.3 by then.
