IDVD Audio

Just finished a FCE (v 3.5.1) project on a Mac G-4 (OS 10.4.8) which included video and photo clips with audio sourced from the video clip or microphone. Exported to QT where both video and audio tracks were OK, then burned the DVD. On some DVD players there was no audio for the first video clip. Audio on the remainder of DVD (which included video clips from the same video camera) was fine.No problem with the video player using other DVD's. I have made many DVD's using the same software and hardware but this is a first. Anyone care to comment? Many thanks, JA

JA - Audio problems can be a symptom of errors during the burning process. High quality media can help (Verbatim is often recommended; I'm very happy with Sony; DVD-R discs should be the most compatible). Burning with a two step process also reduces errors (use Save as Disc Image from iDVD, then copy the resulting virtual DVD to an actual DVD using Roxio Toast or Apple's Disk Utility). Test the disc image to see if it works correctly. When you're finally doing the burn, it's often recommended to slow down the burn speed -- I use 1x or 2x.

IDVD Audio from another Project

We have a G5 that is shared among multiple users, each one has their own account on the computer. We've been experiencing a problem where when one of our users creates and burns a iDVD project, then another user under their own account creates and burns a iDVD project, the audio from last/other project gets multiplexed with the current project.
I've tried repairing permissions in the disk utility, deleting the encoded assets within iDVD and to go as far as deleting the users home folders, trashing the preferences, but the problem keeps popping up.
Anyone experience the same problem and have any success in repairing the problem?
Thanks!

IDVD audio issues

When I burn an iDVD video made in iMovie, this particular one has an audio delay of about a second. When previewing it, in both iDVD and iMoie it seems ok. I have burnt it 3 times creating a different project in iDVD and the same thing is happening. I am a relative Newbie using iDVD but my previous few projects have been fine....???

Welcome to the iDVD forum!
Try gong back to iMovie and "Extract Audio" and then try again in iDVD.
See this post for more info if that doesn't work:

IDVD audio problems

out of 25 dvds 3 work properly. My problems now are: the movie plays fine and then in sum spots my audio sounds garbled, I've tried different DVDs with same results, some work some don't. I have set the properties to encode "professional" with same resluts. I just need one good copy so i can take it somwhere else to burn a lot.

As I said, the setting in is iDVD preferences, not a project setting.
Go to the iDVD menu, and select Preferences.
Click on the 'Advanced' gear wheel icon.
There is a Preferred DVD burning speed setting drop down list, reduce the speed.

IPhoto Slideshow to iDVD - Audio problem

I created a slideshow in iPhoto and added music from iTunes. The slidewhow is about 40 minutes long and I set the length of the slideshow to match the music (about 10 songs). I shred the show from iPhoto to iDVD using the Share option. When I preview the slideshow in iDVD there is only 1 or 2 songs of audio depending on the time I shared it (I tried a few times). The slideshow keeps running, but with no audio. Any help is appreciated.
- Derek

You can get the songs you rip from your CD to export into iTunes by the following:
1. iTunes - Pref - Advanced - Import. Change import using to MP3.
Now all new songs you rip from CD will export with iPhoto
To correct those songs already in iTunes so they will export, do the following:
1. highlight song in iTunes Library
2. Toolbar go to Advanced - Click Convert Selection to MP3
3.Now you will have a duplicate of that song in your library. The one just added that you converted, add MP3 to title
4.Use MP3 song in your slide show.
5. Audio should export with photos.

IDVD audio won't work after installing Audacity

Can you help please?
I am using iDVD 4.0 and installed a 3rd party audio software, Audacity. That's when the trouble started. iDVD kept crashing when I was editing existing projects, and the audio did not work at all in iDVD. I uninstalled Audacity, re-installed iDVD, and am still getting no audio. The audio files appear within the project, but I just can't hear them.
Is there a preference or other file that needs to be removed to fix this? Any other suggestions would be greatly appreciated.
G5 Mac OS X (10.3.8)

Assuming you've first checked Software Update to see if there are any updated drivers and it's still not working, you could try resetting the printing system.
System Preferences>Print & Scan, Control+Click or Right Click on a printer on the left and select 'reset printing system'. All printers will be deleted and need to be added again.

IDVD audio encoding error

I currently have 10 different quicktime files that i've created by exporting 10 different iMovie projects.
I've created an iDvd project and dragged all 10 .dv files in. Everything works well in the preview. the total project is 3.6 out of the 4GB available.
the entire project is on an 250 GB external harddrive attached to a mac laptop (so having available space is not the problem, i have over 130 gigs free)
i press burn, and the encoding begins. everything's running smoothly for two hours, all the videos are encoded. once it reaches "Audio encoding" i come across an error. it recommends me to "Delete Encoded Assets" and try again.
Which i have, and it's still not working.
Something about the Track.
i've created dvd's before with this exact same hardware. I even just created one now, using just one of the quicktime files. For some reason, this big project just won't happen and i'm on the edge of reason here.
I'd appreciate any help.
Mac OS X (10.4.1)

Is there any audio associated with the video?

IDVD AUDIO ENCODING .. APPLE NEEDS TO FIX IT!

It would be nice if they would reply to this. I cannot complete my projects.
After trying EVERY TIP on this 200 + posts on the subject ( except pulling my RAM out ).. I have found only one solution:
Using iMovie .. save back to your camcorder.. then
Open iDVD and use the "OneStep Movie" feature.
Time:
30 min iMovie = 30 min. back to camera + 30 off of camera to iDVD + 30 min for encoding. ( approx )

..also .. when encoding ( video encodes first ) .. as soon it gets to audio encoding .. the Activity Monitor shows iDVD as "Not responding" as well as a 10% or lower ( which seems to be 5% with dual processors ) processing CPU power when the "audio encoding starts" .. this is trhe same thing that HANGS FOR HOURS .. on the SAME video.. but a few short min. later ( if you use OneStep DVD ) the audio finishes ( you wouldnt know from the progress bar, but the Activity Monitor shows iDVD jump starting .. and the processor kicks back in gear) ..and burns the DVD..
What a pain in the *** ... but it works.

Idvd audio troubles

When burning a slideshow from iDVD, which includes some movie clips from our Canon camera, the audio from the last movie clip starts in the middle of the slide show. I have other music loaded from my itunes library, but the audio from the movie clips overrides all other audio. This only happens after burning. It works and sounds great when reviewing in iDVD. Is there anything i can do to prevent this?

I burned the music to a CD, reimported using the AIFF format, and used the Disk Utility Manager to save the file to my desktop and then burned the DVD using the Disk Manager....still no luck. The movie clip audio still cuts in about half way through, overriding all other audio on the DVD. Sounds and looks fine while in iDVD. Any suggestions?

IDVD audio sync problems after Lion upgrade

Hi all,
I posted this in the Lion discussion, but thought I might have a go here as well. I'm having problems with iDVD and audio sync as follows...
I often download files from my Beyonwiz PVR, convert them to mpeg and DV files using MPEG Streamclip (with Quicktime MPEG playback component), then burn a disc with iDVD. Since upgrading to Lion, I notice that the audio in these files, and the burnt DVD in particular, can be slightly out-of-sync with the video. Although the effect is slight, I find it very unacceptable - its like trying to watch something that been badly dubbed. I find it to be a very jarring effect to watch voices and intonation out of sync with the picture.
I'm not sure where the problem lies - is it Quicktime, MPEG Streamclip, and/or iDVD ? I never had this problem at all with Snow Leopard.
Fox

I've discovered that the problem appears to be the conversion of the mpeg file to the DV file. The video/audio goes slightly out of sync using MPEG Streamclip under Mac OS Lion. I never had any problem with Snow Leopard. I'll have to try different conversion methods and see what happens...

IMovie to iDVD, audio is scrambled.

Greetings
I have been using iMovie to iDVD for sometime now, though I am no pro, I have never encountered this type of issue. I have about 100 clips which I are now in iDVD. While verifying the clips and titles, etc., I played a few of my 12 chapters. I noticed that the audio was 'scrambled'; the audio can't be understood at all! Too weird. (There is no problem with the video).
Now I must admit that I am using different audio tracks than ever. For much of the video, I have set the 'main' audio to 25 or 50%, while the secondary audio has music, which is set to 50 to 70%.
I can't seem to figure out why this is happening. And to clarify, 'yes' the audio and fades are great in iMovie.
Your help has always been helpful, I thank you now for your help in helping me figure this one out.
Martin

Martin,
Try going back to iMovie and use the command "extract audio"
This separates the audio and video in your DV stream. You should still be able to set volume controls. Then try again in iDVD.
Also check your audio (from the video) is it 16bit?
John

IMovie to iDVD-audio, slides and videos stuff up

Possess a Powerbook G4, DVD burner.
Did a project using clips and video clips. Share it with iDVD. Tried previewing it.
Audio plays and stops intermittently. Clips do not move and show sequentially. Audio keeps playing and stopping intermittently but clips and videos did not play as sequenced in iMovie.

thanks, it did work later. Now there is problem with
opening it after being burnt onto a disc. I tried
opening it but there was a message that says
"An error occurred while loading the project. This
project seems to be write-protected and cannot be
opened."
what happened?
What are you trying to open?
If you are able to burn the disc, you surely had the project open.

IMovie iDVD Audio Sync

There appear to be a couple of topics on this, but none exactly clearing things up for me.
I have just finished editing our wedding movie, running to 50 minutes. It uses various pieces of iTunes music, extracted audio clips from the original footage and photos. There are many cross fades, crossing over of audio tracks, gaps, etc. In places it is (even if I say so myself), beautifully edited to the music. I have added chapters, and carefully watched it several times in iMovie. It runs perfectly.
However, when I use the iDVD link and send the movie to iDVD, chapters and all, playback drops out of sync with the music after about 8 minutes. It ruins the movie, as there are fast cuts and changes in one or two places that now look really silly without the right music!
I don't need a permanent fix for the problem, but I do need to find a way of getting the movie to iDVD in perfect sync and adding the chapters. I don't mind ditching my iDVD project and starting over, but re-rejigging the movie in any way is out, as it's taken far too many hours. :o(
I'm desperate to do this right for my wife(!), but also for all our friends and family, who contributed so much to the day. Please help.
Peter

Peter, I've been fighting with exactly same problem when tried to create slideshow in iMovie with mixed audio, video and chapters. Plus, in my case there are always rendering glitches in iDVD if chapter marker between two images.
your approach to make full quality DV is right. However, there is a better way to combine it back with chapters instead of re-importing again into iMovie (takes time and disk space) and creating markers second time. You can export iMovie project as DV stream, then extract chapter track from hidden reference movie inside iMovie project, and combine it in QuickTime Pro with DV stream. Works great in my case with iDVD after that. Remember don't be tempted to export also track called "iDVD Compression markers". I think it does more harm then good.
Anyway, I have put together short illustrated guide how to do it:

IMovie to iDVD audio problems

Hello,
I am using iMovie '09 (version 8.0.4). I have created a movie with mp3 audio files playing in the background with the clip volume at 0. The video clips are interspersed with some images every now and then as well as transitions. The movie plays quite well when i preview it in iMovie.
I then share the movie with iDVD (version 7.0.4). When I play the movie in iDVD, almost the entire thing plays perfectly except for this one little part. In that little part, audio from some clip starts playing along with the background music.
More things about my project:
1. I am using audio ducking only once, I know where it is in the timeline and it is working just fine
2. Where the problem occurs, I have looked if I might be doing something wrong in precision editor. Turns out I am not using precision editor on the clips where the audio problem occurs at all
3. All video clips around where the porblem occurs are at a volume of 0
I am confused. Please help.
Thanks.

Hi
*No audio on DVD disc.*
Most common origin.
1 Imported audio from iTunes.
• In iTunes copy out as an audio-CD .aiff
• Use this in Your movie project
2 Strange audio formats like .mp3, .avi etc.
• Change them to .aiff. Use an audio editor like Audacity (free)
3 Main audio is set to off in System Preferences - Does this by it self - Don’t know why
Cheque Audio-Out resp. Audio-In
4. Ed Hanna
Had the same problem; some Googling around gave me a kludgy, but effective fix
Downgrade Perian from recent versions back to version 1.0.
That worked for me, and so far I haven't encountered any deficiencies—except it takes more advanced versions of Perian to enable QuickTime to handle subtitles in .srt format—that I have noticed.
Before burning the DVD.
• Do a DiskImage (File menu and down)
• Double click on the .img file
• Test it with Apple DVD-player
If it’s OK then make Your DVD.
Burn at x1 speed.... (or x4)
• In iDVD 08 - or - 09
• Burn from DiskImage with Apple Disk Util tool
• OR burn with Roxio Toast™ if You got it
Yours Bengt W

IMovie audio stutter+ iDvD audio encoding = Toast ?

In the 8 days since I finally got into iMovie, then iDvD, I've encountered both the skittery / unstable audio Playback of iMovie audio & now iDvd's audio encoding issues . [ app "not responding" while still chuggin' away, etc\etc. ]
It was good to hear from an iApp specialist that these are known issues being 'addressed'.
But it's quite disheartening when a GoOgle ( or Forum ) Search shows woes & hope from 2005 & before.
Will iLife 7 iron out much ? [ or introduce a whole new set for us to spend months grappling with ? ]
My real question here, well the head-of-the-line question ! . . . is > after reading a Macobserver post from 2/06 on Toast 7, I have to wonder if it fills in many gaps and opens the pallette while solving some problems.
It doesn't have slide transitions , but it's work could go to iMovie/iDvd ??
( too many toys in the toybox !! -- pardon my overwhelment )
One hard-fact question that's more answerable is > After my 1st "hung in audio // not responding" Disk Image burn , a Wec-Chat Agent considered it 'dead' & I cancelled it. Is there a headless body in a folder somewhere ?, and is that what "delete encoded assets" is for ??
_TIA_
~~~=Dave

So !...I'm a' confused w/ all the ways to 'archive'
an iMovie project. i created an .img, a
Data-Disc...which could burn a DvD of the project,
but not open in iMovie...yes ?
Warning: we're going to jump a bit from topic to topic.
• An archive is a backup copy of something. The purpose of the archive is to preserve the thing as it exists today. An archive of an iMovie project "captures" it as it exists today. If necessary, months from now you can use the archive to re-create the project as it exists today.
• The archive can take many forms. It can be stored as a disk image — a file stored on your computer that uses a .dmg suffix and looks and acts like a hard disk. Or it can be a ".zip" file created in the Finder. Or it can be a simple duplicate of the project stored on a hard disk or DVD. (A disk image file or zip file does not save significant hard disk space. An iMovie project can't be compressed to any significant extent.)
• iMovie's menu command File > Burn Project to Disc is there for the convenience of iMovie users wanting to copy the project to a DVD — as a computer file. But iMovie can burn a DVD only if the entire iMovie project fits on one disc. Technically, it doesn't create an standalone archive, it simply copies the project — with all the files and folders the project contains — onto the DVD, then burns the DVD.
• The Finder lets us create an standalone archive of a file or folder, using the File > Create Archive Of command. The command copies everything to a file that has a ".zip" suffix. If we want, we can tell the Finder to burn the zip file onto a DVD. The zip file has to fit on one DVD.
• Backup applications like Retrospect can create archives too. Retrospect can store the archive on a variety of media. The backup is stored in a format only Retrospect understands.
• Most of us also have another backup solution available to use with iMovie. Exporting the iMovie project back to tape is a good backup. For most projects, the clips return as clips when the tape is re-imported to a new project. Clips like titles and transitions are no longer editable, of course. Note you must re-import the material to access it.
IS there a way to save a 29 GB project to one DvD
• Regrettably, no. An iMovie (or iDVD) project cannot be larger than will fit on one DVD. Most iMovie projects are larger, of course. For them, the File > Burn project to disk command cannot be used.
• Software exists, however, that lets us back up an iMovie (or iDVD) project across multiple DVDs. These include Toast and Retrospect, the pre-eminent Mac backup software.
• iMovie projects stored on DVDs have one huge disadvantage, however. We must copy the project back to the hard drive to open it in iMovie. iMovie doesn't let us open a project stored on a DVD, for Movie can't write to the disc. (The DVD is, by definition, a locked medium.)
Note too that if the backup DVD is created by Retrospect, Retrospect is required to copy it back to the hard disk. (Sorry, I'm not familiar with Toast.)
• The Finder's File > New Burn Folder lets us burn computer files to a DVD as files. It can copy disk images, zip files and any other kind of computer files and folders to the DVD. Used in this way, the DVD functions like a small hard disk. It can't burn across multiple DVDs.
• A DVD containing data files is different from the DVD iDVD normally creates for us. DVD Normally creates TV-playable DVDs, not data-file DVDs. For these, iDVD encodes the video of our iMovie projects as MEPG-2 video, the language a DVD player understands. No computer data files are involved, at least not files a computer normally understands.
• The iDVD command File > Archive Project serves a different purpose than the archive of an iMovie project. Yes, it backs up the iDVD project too, but we usually make it for a different reason.
The iDVD project has no video or audio of its own, just a link to the reference movie iMovie stores inside the iMovie project. If we want to be able to burn a DVD of the current iMovie project some time later, or burn a DVD after the iMovie project has been discarded, we will have a problem. The source material may be gone. The iDVD archive solves this problem by storing a copy of the source material inside its archive.
So If you want to preserve an iDVD project as it exists today you can tell iDVD to create an archive the includes all the necessary source material from the iMovie project. Now the source material will be "static". We can open the archive sometime later, edit the DVD menus if we want, and burn another DVD.
• iDVD also offers the File > Save As Disk image. This command is not associated with archiving. This command is almost the same as burning a DVD, but it "burns" the encoded material as a disk image file instead of a physical DVD.
The disk image can be played in DVD Player on our Macs, and we can use Disk Utility to burn a DVD of the disk image.
"Burning" a disk image from iDVD is a good way to check the encoding by iDVD. If the disk image "burns" okay, the physical DVD we burn with Disk Utility will probably be okay too.
• As you suggested, the best solution may be an external hard drive. It's not only the easiest to use, it lets us access the iMovie project whenever we want.
• Much of what I've said is associated with routine backups, so I want to say a word about those. We always need backups of our important projects. At the very least, we need to keep a copy on a separate drive. Drives fail.
Experts say that we need to back up our computers daily, and maintain three backup copies, called backup sets. We need two backup sets that we alternate every day or so, both stored on site. And a third backup set stored off-site. (Off-site because our beach house may burn down and the high tides caused by global warming may carry the ashes out to sea.)
Retrospect does an incremental backup for me each night, backing up all the Macs in the house. The on-site backup not being used by Retrospect is stored in a fireproof data safe — a fireproof paper safe isn't cool enough. The third backup set is stored in a safe deposit box at a bank. I rotate the bank set every month or so with one of the two in-house backup sets. The two in-house backup sets are rotated every few days.
For backup media I use "bare" drives connected to a Firewire "dock", like this ComboDock. The drives snap on/off in seconds.
http://www.wiebetech.com/products/ComboDock.php
• Some on-line retailers include Retrospect with the drives they sell.
Hope something here is useful.
