Dolby Digital in QuickTime?

Now that Apple TV can handle Dolby Digital surroundsound, will it work in QuickTime player too? Anyone tried this yet? It would be nice to be able to export a movie as a QuickTime with AC3 audio in it.

Did you look at this thread?

  • Dolby Digital 5.1 pass-through and Quicktime

    All,
    I have found a perplexing issue and I'm not sure what to make of it. I have some movies which, if played through my AppleTV and receiver, outputs Dolby Digital 5.1 quite nicely. If i take the same exact movie file and play it through Quicktime or iTunes (my computer is connected to my receiver via the optical cable), I don't get Dolby Digital.
    Anyone have any ideas why this is?
    Carlos

    Quicktime does not support AC-3 passthrough (DD 5.1) which is what iTunes uses as framework. It does support AAC 5.1

  • Can't TAG Mp4 files with Dolby Digital AC3 5.1

    Hi everyone, I use iTunes to TAG all my Mp3 and Mp4, I have over 100,000 Mp3 tagged with iTunes without no problem and over 2,000 DVDs concerts, TV series, etc in Mp4 format tagged also with iTunes without any problems, all my Mp4 til now have 2 channel stereo sound.
    My problem now is that I'm making some Mp4 movies with dolby digital 5.1 and this Mp4 play perfect in iTunes and QuickTime ''but'' I can't TAG them in iTunes because of the AC3 5.1, I'm sure of this because everthing made in 2 channel stereo have no problem to TAG in iTunes. If I TAG them its seems in the begining to write the TAGs but if I clear iTunes and then re-load again the files the TAGs dissapears.
    I use MAC and PC. I use Nero Recode 2 to make my Mp4. I have the last version of iTunes and QT.... I have noticed that Winamp can write the TAGs without any problems and stays there but what I need is to iTunes recognize that TAGs because I run all my libraries in iTunes
    Thanks in advance, sorry for my english.

    Anybody please, any answer can help me please... Is that no body has experience this same problem?
    If iTunes can't support TAGs with 5.1 is possible to fix this in the next update?
    Regards

  • Cannot select iTunes Audio Track 2 / Dolby Digital

    Hello,
    I have a sound card (from Maplin, CMI-8738) with digital optical output configured to use SPDIF output and connected to a Denon Surround Receiver. The sound card is outputting dolby digital fine, when I play a test Dolby Digital encoded file on VLC media player (although this doesn't play on iTunes, it proves that my system can play dolby digital).
    However, when I downloaded the movie trailer "Scrat's Continental Crack Up, Pt. 2" from iTunes, there were 2 audio tracks displayed from the "Get Info" right-click menu (stereo + Dolby Digital 5.1) but only one is selectable whilst the movie is playing - English (Audio Track 1). English (Audio Track 2), which is the 5.1 track is grey and cannot be selected.
    I'm pretty sure the second track is the 5.1 track, as I've also downloaded rental movies which have a "surround audio" track which is also not selectable.
    iTunes must have a reason to not allow access to the second audio tracks. I've also tried in Quicktime and it does exactly the same.
    I have the latest iTunes 10.6.1.7 / Windows XP.
    Any ideas?
    Martin Dye.

    See if this can help you (last part where I mention about the settings for allowing exclusive use for applications.

  • Workflow to get a dolby digital 5.1 surround, alot of confusion.

    what I have usually done with my videos is to export omf to logic , and mixed in 5.1, from there i bounce in multichannel audio file, and open it i compressor and create there my AC3 file
    is that all to get a professional accepted DOLBY DIGITAL FILE AUDIO file?
    what is real professional workflow used in feature films and main studios? I SEE hardwares around as dolby e  etc
    please help me to clear my confusion

    These are the specific specs requested by a specific facility.  They requested a quicktime with the surround sound tracks muxed (combined with the video) in this fashion.  The other DCP's I've delivered either had stereo tracks or we supplied seperate audio files for each surround sound channel.  So I wouldn't use these without talking to the facility making the DCP.

  • Dolby Digital or AC-3 from MP4 files

    I have MP4 files which I have made that have one stereo soundtrack and one Dolby Digital soundtrack. Is there any kind of plugin so that the latter can be played by Quicktime?
    I have tried VLC as an alternate player. The AC-3 soundtrack does not lock this app up (as it does with Quicktime), but VLC will not play it in surround, either.
    I've tried this with my iMacG5, my iBook G4, and my new Mac Mini. I'm using an M-Audio Transit with the Mini. It works fine for AC-3 from DVD Player but not with MP4 files with pass thru AC-3.
    Does anyone have a suggestion for any other "super tight" video encoding that will preserve multi-channel sound? (My understanding is that H.264 only supports 2 channel sound.)
    Thanks.

    In the Properties for: Built-in Output under "Audio Output" on the right I have:
    Source: Digital Out
    Format: 48000.0 Hz 2ch-24bit
    Is that OK or should I change it to something else?

  • Compressor handled Dolby Digital fine but hangs on H.264

    Hey folks
    Hopefully this is a newbie question..... I search the forums and couldn't find this answer.....
    I have a HDV movie that has been put into final cut pro.... I may have 1 or 2 holes in my audio which is fine I don't mind the silence....
    I sent the project to Compressor and chose HDV 90 minutes since it is about 60+ minutes of footage......
    Compressor handles the Dolby Digital Profession 2.0 find (in about 10 minutes) but then when it goes to H.264 6.75Mbps it litteraly takes for ever....After 11 hours it was only 40% done....
    Is this right or could I have done something wrong in the editing for it to fail?
    -David

    I've had luck with H.264/AAC from Quicktime Player 7 and Adobe Media Encoder. I've never been able to export to Android out of Compressor. The AAC flavours Compressor offers aren't to Android's taste.
    Here's the spec sheet on what is/isn't accepted.
    http://developer.android.com/guide/appendix/media-formats.html
    Also, for the record, Google supports and actively contributes to HTML5. The hang up is the video tag in HTML 5 does not specify a codec. Google is dropping support for H.264 video in Chrome when using the video tag because H.264 is proprietary, not open. This is the same reason H.264 video support has never been in Firefox. H.264 will be supported in Chrome through Flash, just as WebM will be supported almost everywhere else via Flash.

  • How to play Dolby Digital 5.1 soundtrack in a movie with iTunes (PC)?

    I can't play Transformers: Dark of the Moon with Dolby Digital 5.1 soundtrack. It's simply greyed out, I can choose English Stereo and Hungarian Stereo. I played with the settings, but no luck. I don't know it's hardware related or else, I even try QuickTime, but it doesn't even play audio or video, just grey window.
    My PC:
    Windows7 32 bit Home Premium
    Pentium E5300
    2 GB RAM
    Geforce GT 440
    ASUS Xonar DSX
    Genius SW-HF5.1 4500

    Hi MW
    I have checked User s manuals for F10-140 and on page 32 I have found this:
    HEADPHONE (S/PDIF) JACK This jack lets you connect peakers or stereo headphones (16 ohm minimum). When you connect a speaker or headphones, the internal speakers are automatically disabled.
    This jack can be used also as S/PDIF jack and enables connection of optical digital correspondence apparatus.

  • Don't Want Dolby Digital For Stereo Outputs

    Hi, all.  Although FCP X won't natively see the 5.1 tracks of a Sony CX560, it does get the stereo version.  That stereo version seems to be a Dolby Pro Logic mixdown of the 5.1 recording though and plays nicely in surround when decoded with Pro Logic.  This of course doesn't happen when that stereo mix is encoded as Dolby Digital because when a stereo Dodby Digital bitstream is decoded, it will only play through the left/right speakers.  Unlike some other applications, FCP seems to ouput everything only as Dolby Digital, regardless of if it is surround or stereo.  So my stereo "Pro Logic" recordings are only playing out the left/right speakers.  Is there a way for FCP X to not output stereo mixes as Dolby Digital?  Or if I buy Compressor, will I have that control?  Thanks.

    For those who care about this, it appears you can't change how the audio is exported when exported to an Apple TV device.  FCP X will export audio as both an AAC stereo track and as an AC3 Dolby Digital track.  If you're trying to accomplish what I wanted to do though, and easy option is to open the exported file in QuickTime Pro 7, open Show Movie Properties, select the AC3 track, delete it and save the file.  This worked perfectly and was very easy to do.  As for the secondary Compressor question, if I decide to, I'll ask that in the other forum.

  • Disappointing - Apple TV Lacks Dolby digital

    It is disappointing that apple tv lacks dolby digital sound. What is the point of watching a home theater movie in High Def without DD 5.1 They need to resolve this issue to be successful IMHO. Any other thoughts?

    Supposedly the hardware of the Apple TV is capable of Dolby Digital and 5.1 (or even 7.1) surround sound. That is it will pass through such signals to the optical out.
    The real problem is that QuickTime (and remember the Apple TV is running Mac OS X and QuickTime) has very poor to no support for such 'high end' audio standards.
    Yes you can pass a 5.1 encoded audio file in WAV format (or possibly AIFF format) to the Apple TV and it will then pass it unaltered to the optical out, which is connected to your AV Receiver and you will get surround sound. But WAV and AIFF are audio only standards, you cannot use them for movies.
    The nearest you can currently get for video in QuickTime is to have 6 AAC channels in a H.264 file. However very few AV Receivers support this sort of audio.
    Basically QuickTime is the problem, and until it has much better support for Dolby Digital etc. there is absolutely no point improving the movie files on the iTunes Store since QuickTime (and hence Apple TV) will not be able to play them. Even the QuickTime MPEG2 component is no better.
    Interestingly, Front Row 2.0 in Leopard now has the ability to play VIDEO_TS folders (via the Apple DVD Player framework). This means you can in Front Row play surround sound and even subtitles for 'movies' stored in VIDEO_TS folders on your hard disk (that have been ripped from DVD). This works because Front Row is using DVD Player and not using QuickTime.
    Note: QuickTime even QuickTime 7.2 in Leopard has for all intents no support for subtitles either.
    All the above makes a Mac mini running Front Row a much better solution than an Apple TV (although much more expensive).
    Apple really need to fix surround sound and subtitle support in QuickTime urgently, even Windows Media Player does a better job!!
    I did read an article recently decrying Apple (and others) for leading to demise of 'audiophile' quality. That is the proliferation of MP3 and other compressed formats over CD quality sound (I personally use Apple Lossless which is CD quality). Likewise currently Apple TV and iTunes force the downgrading from movies with digital surround sound to merely old fashioned stereo.

  • I would like to connect my Apple TV to my receiver using an HDMI cable and pass thru dolby digital. I do not have optical inputs on my receiver.

    I want to connect my Apple TV to my receiver using an HDMI cable. This should allow me to pass thru high definition video and simultaneously decode Dolby Digital material with an HDMI connection from my receiver to my TV without the use of an optical cable (my receiver does not have an optical input). I am unable to decode 5.1 material and don't understand why this is not working. In the audio setting I have Dolby Digital output turned on.

    Welcome to the Apple Community.
    Are you sure the content you are playing has Dolby Digital.

    hi sotim01,
    Thanks for posting!
    1. Uninstall all components,
            Open Device Manager and Uninstall your Conexant audio under Sound and ganing controllers (make sure to place a check under delete driver software for this device)
    2. Open Control Panel Uninstall a program and highlight the dolby component and an Uninstall button will appear.
    3. Open your C: drive and Delete any folder that says drivers if non then continue with the next step
    4. Download this Driver for installation
            Conexant Audio Driver  
    Install it and continue
    5. Open Drive C: now and you should have the Drivers folder back.
          Open that, Open Connexant Open Dolby Gui,  then you should have Dolbyaa for Advanced audio.
    Restart your PC and there you go!

  • ATV3 - I need to enable dolby digital for optical surround sound (netflix and home movies), but when I do this it stops audio coming through TV speakers

    I have a cinema sound receiver connected to Apple TV via optical cable.  When I have dolby digital set to Auto it doesn't come through as dolby digital when watching movies on netflix and iTunes (home movies).
    If I set Dolby Digital to ON it works as expected, but the sound stops working through normal TV speakers (via HDMI).  This is the same for netflix and home movies.
    I tried 16 bit setting, but it made no difference.
    Any advice on how I can get this working - meaning Dolby Digital always on for when I turn my surround sound on and sound through speakers for normal operation?
    Obviously I can change the setting when needed, its just a pain.
    Thanks in advance.

    Hello everyone, 
    here is the friendly and signed driver installation method to enable Dolby Digital Plus in your Encore internal speakers only. This is not an official driver, there is no control panel for Dolby Digital Plus or various sound effects, but tested and has much better and richer surround sound quality as before with factory driver. I guess, this driver tweak can work with any Bay Trail tablet also.
    How can you upgrade Encore sound drivers:
    1. Download signed driver package and extract.
    2. Open Device Manager.
    3. Upgrade your Sound, Video and game controllers
    - Intel SST Audio Device
    - Realtek I2S Audio Codec
    one by one with "Have a disk" method.
    4. Double click enabledolby.reg file and add to your registry.
    5. Restart, and enjoy better sound quality.
    Thanks.

  • G510 Dolby Digital Plus Advanced Audio doesnt work driver problem with Windows 8.1

    Hi,
    my Lenovo G510 has Windows 8.1 64-bit.
    In the system menue of Hardware and Sound I can see two entries:
    1) Dolby Digital Plus Advanced Audio
    2) Dolby Digital Plus Advanced Audio (32-bit)
    Clicking on the first entry a control panel appears. Does this mean that Dolby Digital Plus Advanced Audio is always running in the backround? There is no entry in the systray.
    Clicking on the second entry this error message appears:
    Your current installed version is 7.3.2.2 of the Dolby Digital Plus audio driver. The software needs the driver version 7.5.1.1. Installe a correct combination of driver and software.
    What to do with this? I searched for a solution and drivers but couldn´t find anything.
    Thanks for your help.

  • Media Encoder PCM or Dolby Digital Settings change preset????

    I am about to Encode a 2 and a half hour project from PPRO 5.5 into Media Encoder.
    If I set my format to H.264 Blu-Ray and my Pre set to 1440 x 1080i 29.97 High Quality, My audio automatically sets to PCM Audio? Why?
    When I use the H.264 Blu-Ray with my Pre set to 1440 x 1080i 29.97 High Quality, and I Press the Dolby Digital as my audio instead of PCM, my Preset changes to Custom. (1440 x 1080i goes away)
    Why is this? Is that what is supposed to happen?
    I had read that Dolby takes up less space without losing that much quality.
    I'm trying to encode this file to about 15GB with keeping the best quality Audio and Video I can.
    PPro CS 5.5
    Media Encoder 5

    Jim,
    In case you missed it, his program is 2hours 40 minutes, so in that case, space is at a premium and I would go for the Dolby.
    It is normal for Media Encoder to create PCM audio, that is OK, Encore will TRANSCODE it to Dolby later and shrink it down.
    Edwurd, please see you other posting for more info about encoding size
    Thanks
    Jeff
    Jeff is right.
    Let Media Encoder make the .264 and .wav files and have Encore automatically transcode the pcm to ac-3 (since it's licensed to do so and AME is not). Don't multiplex them into a mp4 or mov container; it'll make it blu-ray illegal (even though Encore will allow you to import it).
