TICKET ARCHIVE -> Sound Quality Issues With Idvd Burn

FlashBac - Oct 21, 2005 - 10:37 am

I have a upgraded OS X. I use Final Cut Express for my business. I use iDVD to burn. The preview in iDVD is fine, but the sound is broken 90% of the time on DVD.

Can you help me?

Thank you!

What are you playing the burned DVD's on -- your computer, another computer, or a standalone DVD player? Do other DVD's work in this DVD player? Has iDVD worked successfully in the past? What version of MacOS X do you use? What versions of FCE and iDVD do you use?

I play the burned DVD's on my computer and on a high-quality DVD player. Both have the same sound disruptions. If I burn again, there are different sound disruptions in different places and the sound that was bad the first time is OK. Yes all DVD's work other than my iDVD movie. I have had intermitent problems in the past with the sound quality and the burns were 75% successful. Now it is 80% unsuccessful.
OS X Version 10.4.2 with Tiger
FCE Version 3.0
iDVD Version 5.0.1

But have burns been successful in the past? Did it work before you upgraded to Tiger? Have you run all of the necessary software updates?

Yes, they were successful in the past - before Tiger but it was still hit or miss. Now it's just miss. Yes, all update have been installed.

Try exporting the project as a disk image and burning it via Disk Utility.

Here's an Apple article on creating a disc image:
http://docs.info.apple.com/article.html?artnum=164927

What you can do is save your project as a disc image, open the file so it mounts as a virtual DVD on your desktop, and open DVD Player to check your DVD content.

Then, once you've checked to make sure there aren't any problems with the disc image, follow the directions on this page to burn the image:

Let me know how it goes.

I tried your suggestions. Now, everying plays fine when I play the DVD in my computer but it is doing the same thing on my home DVD player which work fine with all other DVD's. I am only having a problem with the audio, not the video.

Would it be worth changing the Quicktime Export settings in Final Cut Express. Maybe change the bit rate to 8 instead of 16? What about exporting to a .mp4 video file instead of Quicktime?

What do you think?

TangentIdea - Oct 24, 2005 - 1:18 pm

I'm not using the same version of FCE that you are, but I always export my main sequence using the Export -> Final Cut Movie option. It includes the full quality DV video and PCM audio. It will not reduce quality at all, like most QuickTime formats will. I highly doubt that this will solve the issue at hand, but it will save you a lot of time in the future when exporting for iDVD, and it will keep your videos at the highest quality possible.

I'm out of ideas for solving this, but there might be another tech with more experience in this area, so I'm going to put this question in the open tickets area for another tech to look at, to solve the issue. Sorry I wasn't able to fix your problem personally.

Thanks Ryan,
You really have been great. I would like to learn more about the difference between mp4 and Quicktime so thanks for passing my issue along to others.
Have a great day!

Hi! Try to burn your disc image with Toast 7 (if you have it). It creates more compatible Dvd-videos.
Disk Utility and iDvd have A LOT of problems burning DVD5 discs (dvd video). Are there presentations in your DVD?
You could also try to switch dvd media brand, sometimes this little action makes miracles. If no one of these tricks work, probably your external dvd player has some incomatibilities with iDvd-created DVDs. I hope not!
Let me know if you succeded. Bye!!
