IDVD lack of audio on 12 bit import

Lots of coasters, (looked at articles deleted encoded etc.) but no audio to iDVD. The forums and articles talk about sound synchro problems with 12 bit. To me, a complete lack of audio is not a "synch" issue. Is it a matter of semantics or will iDVD 6.01 simplly not encode 12 bit audio?

I don't think 12-bit audio would effect having no sound at all. As you said, it is a sync issue, so I suspect what you are experiencing is something else. But it brings up some questions...
1) Is the missing audio only with 12-bit audio? Can you hear the audio fine if you import 16-bit audio?
2) What are you importing from? Is this a DV format camcorder or are you by any chance trying to import MPEG files? Multiplexed audio can be an issue with iMovie.
3) Did you check the audio settings of project? On the bottom you don't have volume set to 0 or something like that?

When I import .mov file to Idvd I lose audio in certain clips

The .mov file I can paly everything fine thru quicktime but on import to Idvd I lose audio on some of the clips. Why? all the boxes are checked on the I movie.

Where did your .mov file orginate from? If it came from a camcorder or a digital still camera that takes MPEG movies, then you need two pieces of software to separate the audio from the .mov file. First, download the Free MPEG Streamclip (do a Google search), and once you download that, there will be a link to download the $20 Apple MPEG Streamclip plug-in for Quicktime. MPEG Streamclip is brilliant in that it will convert your MPEG .mov file back to a DV file for proper input into iMovie for editing while the QT plug-in will separate the audio. In it's original form, the audio to your MPEG movie is imbedded into the video. QT will play it fine, but iMovie needs to have it separated.

Variable bit rate audio assets cannot be imported

Extracted some ac3 files from personal content DVDs I authored and burned myself (using DVDSP) to make a compilation. When I try to import these 5.1 ac3 assets, DVDSP is refusing stating: "Variable bit rate audio assets cannot be imported." These ac3 files play fine in QuickTime and other programs that handle ac3 files.
Can anyone help?

Hi:
Please give us some info about the original movie/audio formats and what encoding presets you used in Compressor.

Importing audio - sample rate/bit depth

Hi forum,
I am working on project at 44.1K, 24 bit. Audio elements are being sent to me to be added. Some have come in incorrectly; at 48K, 16 bit. I can convert easily but didn't think I needed to.
I thought by selecting the "Convert Audio Sample Rate When Importing" option when creating the project that would all be worked out.
That is what I've done - and the file seems to be the correct pitch -- yet shows up in the audio window with it's original specs (48/16). Also ... will logic keep it at 16 bit and play all other files at 24 bit?
I want to be sure about this ... something seems fishy.
Cheers
Dee, Ottawa

Hi,
I am re posting.
Regarding the same project: must everything in the arrange window of a project be the same sample rate (and bit depth). My understanding is that there is real- time conversion during playback. That all file types supported by logic - and all virtual instrument samples are converted in real time to conform to the selected bit depth and sample rate of project.
I ask only as I recieved reference sound files to temporarily place in a mix to see how mix will sit when going to Post. Two audio files are almost a semi tone higher than they are supposed to be (which is odd - so I am pretty sure it was just quickly sung in the wrong key at there end). And one file which was supposed to be timed out is not lining up.
I can work around this on this project. And I can simply convert in the sample editor and re import to compare.
But again ... I just want to check my understanding for future reference. The manual indicates differing rates etc should not be a problem. (ie: That Logic allows one to have differing rates and bit depths. Inversely, the M Sitter video implies just the opposite.
I just want to be sure of this for future reference. Any adive?
Thanks in advance.
Cheers

IDVD crashing upon audio import

As soon as I upload an MP3 into iDVD the program shuts down. no trouble importing images or video, or editing text or buttons. This only appears to happen when I bring in a song as background music for a menu.
thanks,
preston

does this happen with all mp3 files or just that one file?
mp3 files are much smaller than .aiff (the preferred format for iMovie and iDvd).
mp3's also lend themselves to corruption more often than .aiff
my suggestion is to try a different file format and see if you still get the same results.

Hi, please help me When I render my project in IDVD, video and audio runs properly, but when I burn it in professional quality and burning is finished there was no audio on the last two chapters, one audio is attached to the clip and the other one is from itunes, pls help

Hi
My first two thoughts
• Shared to Media Browser - BUT as Large or HD - try Medium !
• audio from iTunes - use to go silent
- in iTunes
- Create a new PlayList with needed audio
- BURN this as a standard Audio-CD (.aiff) - NOT .mp3
- use the files on this CD in Your Movie project - I ALWAYS DO - and only use .aiff ever - never .mp3'
My notes on this:
No audio on DVD disc.
Most common origin.
1. Imported audio from iTunes.
• In iTunes copy out as an Audio-CD .aiff (Same as played on standard Stereo CD - no .mp3)
• Use this in Your movie project
2. Low - Free Space on Start-up/Boot/Internal/Mac OS Hard disk makes it hard for iMovie to work as intended.
Down to 1.3 GB and it doesn’t work - especially audio don’t migrate over to Media Browser
(iM’08 & 09)
3. Material in iMovie’08 & 09 - Shared to Media Browser and here selected as Large
large.m4v. It silenced out this project in iDVD. By making a slight alteration - provoking it to ask for a new Share/Publish to Media Browser and here selecting 640x480 - and audio was back when a new iDVD project was created including this movie.
Minuscular - - 176x144
Mobile - - - - - 480x360
Medium - - - - 640x480
Large - - - - - - 720x540 960x540
HD - - - - - - - - 1280x720
4. Strange audio formats like .mp3, .avi etc.
• Change them to .aiff. Use an audio editor like Audacity (free)
5. Main audio is set to off in System Preferences - Does this by it self - Don’t know why
Cheque Audio-Out resp. Audio-In
6. 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.
7. GarageBand fix.
In this set audio to 44.1 kHz (Klaus1 suggestion)
(if this don’t work try 48 kHz - me guessing)
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’s Disk Utilities application
• OR burn with Roxio Toast™ if You got it

IDVD 6 - No audio track on burned DVD?

Ive run into a problem with iDVD 6.0...The project I’m working on was created in iMovie, and then ported to iDVD for final editing and burning. While running the project in the preview mode of iDVD, everything is fine – menus, content, etc. Encoding/burning was uneventful, taking forever on my old G4, but completing successfully. The problem is that when I play the created DVD, there is no audio content to the chapters. However chapter selection screen does have the audio track I added, and does play.
Not sure where I went wrong, as everything is OK in preview mode from within iDVD. The lack of audio on playback occurs in any DVD player, so it leads me to believe something’s missing from the burned disk.
Any thgouts/insite would be greatly appreciated

Are you using iTunes purchased music? If so, it is a known problem. See last post on this thread for a workaround.
http://discussions.apple.com/thread.jspa?messageID=5046586&#5046586
Other things to try
Use a good brand DVD-R like Verbatim or Maxcell
Save project as a disk image
Burn disk image to DVD by using Disk Utility
Burn at 2x speed
Hope this helps

External Audio recording to be imported & used in FCE

Hi there,
I am thinking of using this audio interface to record some vocals. It is a Focusrite Saffire 6 USB. It comes with a software called Ableton Live that can record the sound in wav or aiff format.
http://www.focusrite.com/products/audiointerfaces/saffire_6usb
According to this spec, it uses a *24bit 96kHz a/d covertor*.
http://www.htfr.com/more-info/MR326826
+TECHNICAL SPECIFICATIONS:+
+2 channel USB audio & MIDI recording interface+
*+24bit 96kHz a/d & d/a converters+*
I am using a standard defintion miniDV tape video camera and in my FCE, in the Easy setup, I have selected DV-PAL 32kHZ Amorphic.
My question is, will the sound recorded using this Focusrite Saffire audio interface be imported into FCE4 for editing together to mix together with my video clips (recorded in my standard defintion video camera) ?
Thanks you.
Cheers

QUESTION 1:
I also discovered something strange when I check the settings of all the previous video & audio clips imported into FCE4. Those that imported in from video camera, the values are 16 bit 32 kHz (How come ? My video camera is set to 12 bit 32 kHz)
Despite the material is recorded in 32 bit, the capture process with 48kHz setting are allowed, but on long shot, you can expect a audio drift from video if sequence's audio is not the same as original sources.
QUESTION 2:
Then, I look into all the audio clips I bought from iTunes & imported into FCE4, they are all listed as 16 bit 48 kHz.
The funny thing is that both these type of different clips (ie, 16bit/32kHz & 16bit/48kHz) can be rendered without problem. How come ? FCE4 can mix clips of different audio types ?
BTW, importing iTune purchased song into FCE is prohibited by iTune EUA. Any non-natively supported media can be rendered in FCE, but as explained in question 1, you can expect audio drift on long clip. This problem is not relevant with music track audio which is it not part of a video footage.
QUESTION 3:
If I set the Ableton software output to 16bit 48 kHz, does that mean that I actually cannot make use of the hardware abilities to produce sound of 24 bit 96 kHz ? Is there much difference ?
96 kHz is used for professionnal multi-track audio editing. You have to use high-end audio monitors to ear the difference... if you can. Usually only audio engineers can ear the difference.
Audio CD use 44 kHz and the quality is pristine on hi-fi deck. 48 kHz is the standard in video production and even used in dolby 5.1 home theater configuration.
QUESTION 4:
In the Easy Setup, I cannot find 16 bit 48 kHz. I only have the following option in the Easy Setup of FCE4:
a) DV-PAL
b) DV-PAL 32 kHz
c) DV-PAL 32 kHz Anamorphic
d) DV-PAL 32 kHz Anamorphic Basic
e) DV-PAL 32 kHz FireWire Basic
f) DV-PAL Anamporphic
g) DV-PAL Anamorphic Basic
h) DV-PAL DV Convertor
i) DV-PAL FireWire Basic
So, which one do I chose ?
Use DV-PAL.

No audio on playback of imported mpg2 video clip while editing

I was assisted yesterday by your technical support team to install the photoshop elements 12 & premiere elements 12 which I purchased e few minutes prior.
while trying to work with the premiere elements 12, I realised that I have no audio on playback of imported mpg2 video clip while editing.
How can I solve this audio setting problem?

Is the lack of audio in the Editing area of the program confined to this one particular MPG2 video clip?
What are the properties of this video file? If you do not know
a. perhaps the brand/model/settings of the camera that recorded the video might give us the information we need for troubleshooting
b. if not, consider getting that information from MediaInfo (Tree View)

Just watch out for carry alongs in the download. The link is for the Windows version. A Mac version is available.
Did you discover the loss of audio for the video file after you had created a narration clip with the program's Narration Tool?
If you have not already, please check the settings under Edit Menu/Preferences/Audio Hardware and its ASIO settings (including Input and Output enablement).
Please review, consider, and reply to the above. If you have questions or need clarification on any of the above, please do not hesitate to ask.

Where has the "recordings" options gone in imovie for the iphone? It used to be listed under the audio tab in the import icon.

IDVD will not initialize in 64 bit mode

I upgraded to Snow Leopard and booted up in 64 bit mode. I just discovered that IDVD will not open in 64 bit mode. Rebooted in 32 bit mode IDVD works fine. Has anyone else has this problem or a similar problem with any APPLE apps in 64 bit mode. Is there a fix out there for this type of problem. Any help would be greatly appreciated.

The current iDVD application is not 64-bit. In fact none of the iLife or iWorks applications have been converted to 64-bit. It's not likely they will be since there's a large user base that can only use the universal binaries. There isn't that much use for 64-bit booting at this time unless you are a developer creating 64-bit only applications.
This is not a problem for which a fix is even possible.

I have an iMovie that I created 10 years ago. I found the disk and imported. Everything is there except the sound! I converted in Wondershare to MPV4 but still no sound. There is an audio clip that was imported from an analog video camera.

A small update to this issue....
I have been trawling the forums to find an answer but to no avail...
And... I've tried exporting and bouncing individual stems and the full session, either by muting all bar the stem or soloing the stem.....and still nothing.
Same problems.....everything is audible in audition but nothing plays on playback.
Since the 'prelisten' channel strip is Solo safe this would indicate that you have a track or channel strip soloed somewhere else, out of sight. Are the Mute buttons on your channel strips blinking?
To view all objects in your mixer, click the button. You may have to scroll sideways to check the whole mixer.

24 bit Audio through 16 bit Audio Output

Possibly dumb question but...
I have 24 bit audio files recorded on other equipment. If I edit them in Audition at 24/32 bit but my audio hardware and/or output driver is only 16 bit will that affect the audio processing quality of what I'm doing within Audition?
The output is simply to connect speakers or headphones but everything else such as outputting the processed file to hard drive will be done internally from Audition (i.e. Save As - no mixdowns through external analog outputs or anything).
Will the audio stay 24 bit quality when using 16 bit audio hardware output for monitoring?
Thanks.

No, the files within Audition will be unaffected by the available bit depth of your soundcard. The only time it would matter is, for instance, if you are making CDs from your audio files or feeding digital out to an external 16 bit recorder in which case you will need to down convert your 24 bit files to 16 using dither for best results when you have finished all the editing/processing. But keep the 32 bit files in case you need to go back and do any adjustments.

None of my finished idvd projects have audio, although they did in the past. Also, none of and none of the idvd themes have audio, although they always used to open with accompanying audio.

None of my finishsed idvd projects have audio, although many were finished and had audio before. Also, none of the idvid themes have audio, although in the past they each opened with their own canned audio. Any ideas on where the audio went and how to get it back?

In addition to deleting the iDVD preference file delete the contents of the iDVD cache folder:
Try this basic troubleshooting fix:
1 - delete the IDVD preference file, com.apple.iDVD.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete IDVD'S cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iDVD folder.
3 - launch IDVD and try again.
NOTE: In Lion and Mountain Lion the Home/Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
