IDVD 6 and AC3 audio

Does iDVD 6 do AC3 audio? No? Still only bloated PCM audio, right?
...reportedly iMovie 6 STILL has the same jaggy still image bug that has haunted us since v3 and which keeps the iMovie forums busy. I'm afraid that many other old bugs are still there.
AC3 audio support for iDVD might have been a good cause for me to upgrade but maybe I'll have to use iWeb as an excuse to take a dive into the new features and bugs in iLife 06...

So what does it look like and when does it happen?

FCP and ac3 audio

I use 2 different versions of FCP: I have 5 at home, and use 6 at school.
Recently, I wanted to take a lot of my school files home, for future use (to create a portfolio).
At school, I used their version of Compressor to put the files onto my LaCie to take home. (I did that not just because of the size, but because I am on an older version of FCP at home, so I was hoping this would make them more compatible). I used the setting for DVD (best, 90-min) in Compressor (out of habit, I suppose).
At home, I am having trouble importing the audio files back into my older version of FCP. It doesn't want to recognize .ac3.
Having the whole FC Suite at home, I opened up Soundtrack Pro to see if I could convert the ac3 audio back to aiff. No such luck!
I even tried Garage Band, just hoping there was a chance - but no.
So how do I get these files into FCP, so I can further edit them and make a creative portfolio out of all of my work?

actually I don't think this is correct, FCS1 can encode ac3 files just fine, but that is for DVD creation not editing. If you want to transfer your audio for editing just leave them as aifs.
Best way to transfer from 6 at your school to 5 at home is through an xml file for the project, and then bring your media home.
Or if you want it all in one movie, export it as quicktime, same settings (not QT conversion).

Update 4.1. and AC3 audio

Alas no AC3 audio, anyone else experiencing this?

Bogus! I think that a lot of folk were. I could have sworn that I saw something about it being part of 4.1 - probably just one of those rumors...
Thanks for reporting, even if it's bad news,
Hunt
[Edit] I'm probaby thinking back to an issue with the SurCode DD 5.1 SS plug-in. I know that efforts to fix those issues were underway. That is obviously a problem affecting things in one way ->, but I'd hoped to see things fixed in the other way <-. Hm-m, OK, so it ain't perfect.

Exporting files with AC3 audio

Forgive me if this is not the right place to post this question.
Using QT Pro, I want to trim and edit some files containing AC3 (Dolby Digital) audio. When I export or save the edited video, will they retain the AC3 audio?
More specifics: These files contain both AAC audio (in the default track) and AC3 audio (second track). These files were encoded using Handbrake, and I will be playing them on my AppleTV (hence the desire to retain the AC3 audio). The source files come from my DVR, and I want to trim some commercials. I tried to trim them prior to encoding, but I'm having trouble finding reliable software for editing MPEG2 streams on a Mac. Thus, I'm trying to figure out whether or not I can trim them afterwards using QT Pro and still retain the AC3 audio.
Any thoughts would be appreciated. Thanks!

Aaah, I wish I could help! I have exactly the same problem! I was going to post about it, but since there's this workaround, I didn't want to take up bandwidth with a problem that was not a total showstopper.
Indeed. I have stopped doing what I used to do before. Before, I used to select "All" in compressor - the files generated were the video, the aiff, and the ac3. Well after burning a few coasters through DVDSP 4.1 where there was picture but no sound, I realized that I needed to drag the aiff file to compressor again, and use that - at that point everything is fine. So, right now, my workflow is to export just the video from FCP through compressor, let it encode. Then export the aiff separately and encode it to a3 in compressor, then import the video and ac3 to DVDSP for good results. In short, no more exporting "All" from FCP through compressor, it's a waste of time.
But as to why, I have no idea, and I'm eager to hear what folks have to say! Anyhow, just letting you know you are not alone. Btw. my set up is: FCP 4.5 HD, compressor 2.1 and DVDSP 4.1.0... what's yours?

Need to export an AC3 audio file from FCP

Does anyone know how to export (or convert to) and AC3 audio file from FCP? My compressor is not currently working, is there another way? I have Sorenson Squeeze and FCP 5.0.4. Thank you!!!
alex

Upload your audio file to my Public folder and wait 20 mins. I'll compress the audio to .ac3 for you if you're in a crunch. Check back in my Public Folder and I'll have it there for you.

How do I make a dvd in iDVD out of the audio and video files from Compressor 4?

I created two video files in fcpx and compressed them using the dvd source in compressor 4 which ended me up with a set of a separate video and separate audio file for each video. I want to take these files into iDVD and create one movie file with these two videos. How do I reconnect the separated video and audio files in iDVD? Thanks!

tell me what software they used to achieve this.
iDVD.
Apple sells iDVD on disk as part of iLife 11.
Yes, there are programs that will put a movie on a DVD. I have tried most of the other substitutes including Toast, Burn, and others. None of them come anywhere near the ease-of-use and power of iDVD. IDVD is specifically designed to work with iMovie.
With iDVD you can easily and quickly create DVDs with menus and graphics almost on the level of what Hollywood can do.
IDVD is a wonderful piece of software and well worth the low cost of $40.
http://www.amazon.com/Apple-MC623Z-A-iLife-VERSION/dp/B003XKRZES/ref=sr_1_1?ie=U
IDVD remains a popular application in the Apple community. For a variety of obvious reasons Apple would prefer your movies to be stored on the cloud. Many people however prefer to have a physical copy, that they can possess, that is easily playable on over 700 million DVD players worldwide.

I created in iMovie, and extracted audio from one of the clips to use in the title sequence. All is well, export to iDVD and it plays OK, but when I burn the DVD the audio for the titles does not play. Any suggestions?

5.1 ac3 audio plays and exports as stereo in CS6

I am using the trial version of Premiere Pro CS6 at the moment. I am trying to create a short video that uses an 5.1 ac3 file that I created. I know the file is 5.1 because it plays through all the speakers on my WD TV HD Live media player, as well as through VLC Player on my computer. When I import the audio into Premiere Pro CS6, it plays as stereo. The same is true for audio from the video I imported. The video (from a Panasonic TM700 camcorder) also has 5.1 surround, but plays in stereo.
I went to Edit > Preferences > Audio and set the default audio tracks to 5.1. Under Audio Hardware, the only thing in the dropdown is Premiere Pro WDM Sound. I do not know what that is. My onboard sound card is Realtek High Definition Audio (on an Asus P9X79 Pro motherboard) and it works correctly as far as I can hear from all of my speakers.
Under Audio Output Mapping, there are only two channels listed. Again, Premiere Pro WDM Sound is the only option, and only the left and right speakers are in the list under that.
Does PrP CS6 not support my Realtek onboard sound? Why is it not listing all six channels?
Thanks in advance!

This has been an argument, discussed since at least PrPro 2.0.
Going back to about that point (when Minnetonka Audio offered a discount for PrPro users), Minnetonka Audio basically opened up their books to me, when I inquired about volume licensing. I do not recall the exact prices, or even the discount, but the Dolby Labs' charge was most of the cost, and Minnetonka Audio only made about US $50 per SurCode plug-in.
Now, with the Minnetonka Audio SurCode, one CAN use the DD logo, when certain criteria have been met. With most other 5.1 SS Encoders, they are NOT certified DD, so cannot legally display that logo. Sony, with their Vegas NLE's, seems to be an exception to that restriction. I am not sure what the legal issues are, but Sony does (or did) create DD 5.1 SS, with some of their programs. Perhaps some sort of "brother-in-law deal" with Dolby Labs?
To some editors, having fully legal DD logos is not important to them, or to their clients. In those cases, there are a few other methods (though somewhat convoluted), to Export 5.1 SS AC3's, just not DD-certified.
I used the DD 5.1 SS enough, that I bought a license for each computer, and felt that my $ was well-spent. As you, and others mention, paying the licensing fee to Dolby and Minnetonka Audio, if one never uses the SurCode plug-in alters the price-point of the program, and all users will be paying more, whether they derive any value, or not. To me, it has more than paid for itself.
It would akin to Adobe including the full Red Giant Magic Bullet Looks suite in their program. Price would go up, and many users would never need that, or want it.
If asked, my vote would be to keep things, as they are, and those who want/need the SurCode plug-in can buy it.

AC3 Audio and Quicktime 7.6 Problem

I was wondering if anyone else is having a problem with opening an audio file with the .ac3 extension in the updated Quicktime 7.6?
What I have been doing, for a couple of years now, is that I capture a TV program from my DVR using the firewire port. Once the file is loaded on my Mac, I then open MPEG Streamclip, trim out the commercials, Export to Quicktime using H264 and 2 channel AAC audio, after the export is done, I would then do a Demux to AC3 to get a separate audio only file containing the 5.1 surround sound.
I would open the .ac3 audio only file, open the .mov video file (both in Quicktime). I would then copy the 5.1 audio track from the .ac3 file, Go to the .mov file, perform Edit/Add to Movie. This way I would have 2 audio tracks, AAC a 2 channel track and AC3 a 6 channel track.
But now with Quicktime 7.6, I cannot open the .ac3 file at all, I get "The file is not a movie file." error message with no error code.
Any suggestions?
Thanks,
Bill

POSSIBLE SOLUTION
I think I have discovered a way to workaround the AC3 5.1 sound problem.
I found an old 20GB drive and installed Tiger 10.4 onto the drive. I then downloaded the "MacOSXUpdCombo10.4.11PPC.dmg" file and updated the system to Tiger 10.4.11. I performed all of the updates (System Security updates and the Java updates) through Software Update except for iTunes and QuickTime.
I then downloaded the "QuickTime755_Tiger.dmg" file from Apple and updated to QuickTime 7.5.5
DO NOT UPGRADE TO 7.6
I then opened the TV show in QuickTime 7.5.5, I extracted the audio file from the program and saved as a separate audio file (it saves as a .mov file).
I opened this audio file in QuickTime 7.5.5 and then exported the audio
selecting Export Movie to QuickTime movie,
clicked on the options button,
the sound box should already be checked,
clicked on the settings button,
under the Format drop down I clicked on AAC,
Channels: I clicked on 5.1,
then Rate:48.000,
checked on Show Advanced Settings,
Quality: Normal,
Encoding Strategy: Constant Bit Rate,
Target Bit Rate: 384
(used MediaInfo Mac to gate this information),
clicked OK,
Clicked OK,
then named the file, saved it and then waited for audio to be converted from AC3 5.1 to ACC 5.1.
If you now open up this file in QuickTime 7.5.5 it is an ACC format with 5.1 and plays fine.
I then restarted to my regular drive with QuickTime 7.6 loaded and it plays the audio file without any problems.
I'm sure that there must be a way to repackage the AC3 audio file in an AAC container that will work better and faster, but for now this seems to work, so I am going to try some other shows that I have.
Let me know if this works for others.

Way to edit and save .AC3 audio files?

Anyone know if there is a way to edit and save .AC3 audio files in Audition 3?

Every time you open any coded file at all in Audition, you lose quality if you resave it in anything other than an uncompressed format. With most formats, what is even worse is saving them in a different compressed format, because you end up with twice as many different coding artefacts.
What you need to understand is that all of these formats are distribution formats, not editing ones. The basic principle is that you work in an uncompressed format until the last possible moment - ie, distribution. And that, ideally, is the only time you use a compressed format at all. So if you want to use something that's compressed, you uncompress it once, and don't recompress until you absolutely have to.

Quick time audio, and ac3 filter

I recently downloaded some video clips, the video played well in Quicktime but there was no sound; one message from QT said ac3 audio isn't supported since it' no good I (QTpro) will dump the audio.
Hm....it came with High-Definition video clips.
A friend told me to go to
http://www.versiontracker.com/dyn/moreinfo/macosx/27300
-there I got MacOSX4 compatible software: the ac3 audio plugin, as well as instructions on which folders I should copy the software into, in OSX4.
Now my clips plays beautifully WITH sound- except if I try to merge 2 clips using QTpro-then the sound disappears-thanks to lackings in QTpro.
My questions: 1) What's with that arrogant "is no good" message about ac3 audio? No QT audio was ever better....
2)When does Apple pull itself together and provide full ac3 sound support in QT??
Mac mini Mac OS X (10.4.8)
Mac mini Mac OS X (10.4.8)

1) What's with that arrogant "is no good" message about ac3 audio? No QT audio was ever better....
Have never seen such a message. If I attempt to open an AC3 audio file (without AC3 codec installed), I simply get a modal error message saying the file could not be opened. If I open a video file with an AC3 audio track, I am simply notified there is a missing component. Could you describe how you get this message?
2)When does Apple pull itself together and provide full ac3 sound support in QT??
Am hoping that Apple will be addressing the problem the first quarter of next year with the release of the "iTV" device. Seems like it would be a real waste to have a Toslink optical connector and not be able to connect AC3 to your A/V Dolby Digital decoder. Don't even care if the add any AC3 support. All I want them to do is add the pass through (encoded output) capability to QT/iTunes just as they have to their DVD Player or as VLC has had in their media player for some time now.
Now my clips plays beautifully WITH sound- except if I try to merge 2 clips using QTpro-then the sound disappears-thanks to lackings in QTpro.
Muxed MPEG-2 files are only MPEG-1 Layer-1/Layer-2 audio supported. If you want, you can use MPEG Streamclip (free) to convert files like decrypted/unencrypted VOBs directly to MPEG-2 with MP2. Files are simply de-muxed and the AC3 mixed down to stereo (default setting), converted to MP2 and muxed back with the original MPEG-2 with no loss in video quality. Files play fine with audio in QT Player with MPEG-2 component installed.

HT1583 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

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

How do I get AC3 audio on my DVD

Hi,
Thank you for reading and offering your help.
I want to make some DVDs using iDVD09. I have no problem creating and editing videos and burning DVDs using iDVD.
Here is my problem. I want to create DVDs that will be duplicated by a company that says no Mpeg audio. They want AC3 audio.
Could someone please help me out here. What do I do, so that I can create a video, use iDVD09 and have AC3 audio? Or if that can't be done, please tell me my options.
Thank you very much.

I don't have first hand knowledge of iDVD on this, but here's a post that suggests iDVD won't be able to solve your dilemma (unless the production house accepts PCM audio -- check this):
http://www.mhvt.net/quicktime/eng/idvd.php
DVD Studio Pro offers a greater range of audio encoding options, including AC3. You may wish to check Toast and other software, but if you like nice menus, you may be looking at Apple's Pro$$ software.

MPEG videos with AC3 audio in iMovie

Hi there,
Aplle seems to totally ignore AC3 audio streams (at least in MPEG videos)! Why?
My JVC cam corder records *.MOD files on its hard disc. Those files
are in fact MPEG2 files, but with AC3 audio.
Renaming the files makes them playable using the Quicktime Player, but
without the sound
MPlayer is able to play them correctly, but that does not help me,
because I want to use the videos in iMovie and iDVD.
I tried installing the 'AC3 Codec.component' (what is supposed to fix
the problem for AVI files)
and now I installed Perian, which does not do the trick either.
I can ofcourse use ffmpeg to convert the files, but that means a
quality loss and a lot of work I wanted to save by buying a Harddisk
camcorder, so I could skip the time consuming conversion from DV tapes
to mpeg.
I there anybody out there with a solution?

QuickTime doesn't like to play the multiplexed sound on mpg videos. The QT Plugin ONLY supports video playback and NOT the audio track of such content (as you have found out).
I suggest you look at VisualHub software ( http://www.techspansion.com/ ) to convert your files to DV. It works with my problem mpg-4 files with multiplex audio. It runs in a free trial mode so you can verify it does what you want before buying it.

Help!! idvd freezing when rendering audio

PLEASE..I need help!! I make a movie for my students at the end of the school year. I put together a movie in imovie and then sent it to idvd. When I finished with the idvd part and went to burn it, my idvd would stop responding after about an hour when it came to the final part when rendering the audio. I find I have to force quit the program and start over. I've tried it 4 times and it happens every time in the same spot. I never had this happen before. Thanks for any help you can give me!!

Like I said!
This question is frequently asked!
iDVD is probably not 'hanging'. Disregard any messages that iDVD is not responding. It is. Do not force quit.
Encoding audio is the slowest part of rendering, and can take many hours. Great patience, even an intermittent alternative hobby, is called for.
Make sure no other application is running, make sure you have not set the hard disk to go to sleep and that the screen saver will not come on. Leave it overnight, or have a 36 hole game of golf.
Sooner or later iDVD will finish!
