FCPX dolby digital output

Hi,
I am considering buying FCPX. I saw that FCPX allows you to create a 5.1 signal from a stereo feed through audio keyframes and audio placement (L, R, C, rl, rR) of these keyframes.
But, when you do that, will FCPX export your audio as 5.1 dolby digital source or a simulated 5.1 thus a dolby surround track?? I think a home cinema receiver will need a *.ac3 signal to have a true "Dolby Digital", or else it will consider the audio as stereo. Do you need Motion to export Dolby Digital?
Has anyone experience with this? Any input would be appreciated.

Hi G.H.,
Since you use the same camera, I was wondering how you use the surround audio panning mode. I created a 5.1 surround project 1080 50p. I see 6 channels in the audio meter, but when I create >1 keyframes with the surround panning, the audio position does not shif even when a new keyframe (with another setting of my position) is reached. How did you resolve this?
Do you use 6 mono channels or do you leave 5.1 audio (standard)?
rgds,
Tom

SPDIF Dolby Digital output of K7N420

Hello,
I have two computers, and the SPDIF output of one computer (the K7N420) is running into the SPDIF input of the Live! Drive of the other computer. When I select "Stereo" or "Dolby-Surround" for the digital output in the nforce control panel of the K7N420, the signal gets through just fine. However, if I select "Dolby-Digital" nothing comes through. Does anybody know why?
The FAQ for the Live! Drive says "The Optical In and SPDIF In can accept PCM (20 bit, 48kHz, stereo)."
However, I can't find anywhere what the nforce's SPDIF output is when in DD mode. Could this be why?
Has anybody else run across this problem?
Thanks,
-Arpad

Dolby Surround was the name for the older technology, also called Dolby Prologic.
It is backward compatible, which means that if you play a DS stream to a stereo decoder, it will get only the 2 "classic" channels (left & right). If you play it to a Dolby Prologic decoder, additional infomation (hidden in the usual 2 channels) are displayed.
for more information, let me refer you to the dolby knowledge base.
Hope it clarifies the point.

PS: there are lots of interesting info on that website, take a lok if you are interested in DD, DS, 5.1...

Mac Mini - Dolby Digital Output?

I just bought a new Mac Mini (base configuration) to use as a HTPC. I also bumped the memory up to 8 GB. The mini works flawlessly. I copied my iTunes folder over and authorized the computer.
I placed the mini in the same place that I had a new AppleTV, attached it to the TV with an HDMI cable and to the receiver using a toslink to optical mini plug digital cable. Everything works great except the receiver indicates that the audio is “PCM” not Dobly 5.1. When the Apple TV was connected to the receiver in the same way, playing the same movies, it always showed Dolby 5.1.
I also tried changing the audio out to the HDMI cable and connected the receiver to the TV optical out port and I get the same thing.
Does the mini output Dolby? If so is there a setting I am missing?

There seems to be alot of issues with the new Minis
as far as Dolby/DTS pass through are concerned. In one
of the threads in this forum, there was some mention that
a simultaneous HDMI and optical connection can create
this problem. There was also some one who said an Apple
person told them that this is not possible on the new
Minis. Others have found workarounds that sometimes work
for specific apps.
When all the posts are taken in total, it just seems no one
really knows what is going on and how to fix it, other than
finding a 2010 Mini laying around in a store somewhere and
getting it.

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.

How do I get Dolby digital live or DTS connect to work?

I have the sound blaster Zx sound card and the logitech z906 5.1 surround speaker system. I am connecting to the speakers via optical cable. I figured Dolby digital live and/or DTS would sound great with this set up, only problem when I turn on either of those my speakers go silent. I set Speakers: Soundblaster Z as my default playback device but other than that I am not sure what I need to do to get it to work.

I have the z 906 speakers, not the Z-5500 in your link. The manual I already have says the z906 speakers automatically detect the digital signal. I figured the Sound Blaster card would convert an analog signal to digital since it is going into the speakers through the Optical cable, I guess I was wrong.
I have read the link about digital connections on these forums along with the notice in the cinematic tab in the Sound Blaster control panel. I believe they are both saying that I will not be able to use my music player (windows media player) in conjunction with the Dolby DTS and Dolby Digital Live, is this true?
If so then is the only way to listen to the DTS or digital Live effects is through a DVD or Blu ray disc encoded for either of those effects?
If this is true how do I test my dolby digital outputs to make sure they are working correctly?

ATV 2G, iOS 4.2 Update and Dolby Digital not playing

I'm hoping a few folks here have experienced the same issue and can point me in the right direction. I realize that there have been a few threads about this, perhaps with a slightly more pointed question I can at least get something going. To wit:
I recently upgraded to iOS4.2. Everything runs fine, except the Dolby Digial output. If I have this enabled/auto, and I select a video to play, it will hang indefinitely while it attempts to load. These movies all worked under the previous firmware version, and selecting Dolby Digital output "off" allows the movie to play as it normally had (albeit without 5.1). What changed between versions that now causes this error to occur? What do I need to do on my end to get 5.1 audio working like it was prior to upgrading to 5.1?
This is very frustrating!

It's a bug, it effects ALL ATV 2 units running iOS 4.2 and 4.2.1. The bug was introduced at iOS 4.2. There are various workarounds to get your DD to play. Easiest is to start the video, press down arrow, skip to end, let ATV go to menu, select video again (it will play now with DD, if it doesn't just do steps over again).
If you are not effected then you are just not doing it right, but you DO have the bug.
The bug has been logged with Apple, feel free to log it again or call and complain. There is not an issue with your ATV physical hardware. Its a software bug. It is repeatable with ANY ATV 2 unit.

ITunes rented movie not outputting Dolby Digital 5.1 audio

The problem with the downloaded movie (Real Steel HD) is
that the Dolby Digital 5.1 (English) audio is not being putput. The movie is only playing back in
"stereo" mode. When playing back on iTunes there are four audio tracks
to choose from:
1. English 1 (This plays stereo)
2. English 2 (NO SOUND) - I believe this should be the Dolby Digital track
3. French (This plays stereo)
4. Spanish (This plays stereo)
Neither of the two English tracks is outputting Dolby Digital 5.1 audio.
I have confirmed that my PC is capable of up to 7.1 surround sound and
my A/V receiver is capable of even more. I have updated both the ATI
Radeon 4500 driver and the Realtek drivers. I have tested and
confirmed that my PC is capable of outputting sound to all 5 of my
speakers and my subwoofer, HOWEVER when playing back the rented movie
in iTunes the maximum audio is stereo. I have the latest version of
iTunes installed, so that shouldn't be the problem.
I have also purchased another movie advertised as Dolby Digital 5.1
audio (The Bourne Supremecy HD) but I am afraid to begin my 24-hour
viewing period because of these audio problems being unresolved.
My question is: Are there known issues of movies purchased on iTunes
and played back on a Windows 7 PC not playing the Dolby Digital
tracks? If so, is there a fix for this via an iTunes settings change
or a Windows update patch?
From the four audio tracks that I listed above, I believe track 2 is
the Dolby Digital track, yet there is NO SOUND when that track is
selected.
Please help, as this is pretty frustrating when your movie night is ruined for the family especially after you've paid for and waited for the movie to download.

I managed to get my DD tracks working.
First had to update itunes to the latest version (10.7.0.21) to get rid of the out of sync sound problem
Then updated the realtek driver. There was an update directly in the realtek website (mine is the HD Audio): http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24& Level=4&Conn=3&DownTypeID=3&GetDown=false
After all that. I tunes wasn't allowing anymore to select the Doubly Digital 5.1 tracks (an improvement).
Then went to the windows properties for the realtek optical output and checked both options to allow application exclusive access and to have priority (http://dailykermit.wordpress.com/2009/09/11/windows-7-exclusive-device-control/)
After all this, I was able to enjoy my rental

What settings need to be adjusted to send out Dolby digital ,DTS from inputs such as Netflix to the video output via an adaptor to HDMI?

Hi. I can only stream picture and PCM out of my Mac BookPro. What settings need to be adjusted to output Dolby Digital or DTS to an HDMI adaptor had thence onto my AV Processor?

The Audio Midi Setup utility may need to have its settings updated.
That's if you have the right adapter:

FCPX, Compressor and Dolby Digital 5.1

Hi all,
I had Final Cut Pro 7 HD and gone over to FCPX.
The Apple Store in Sydney told me to burn a disc with 5.1 surround sound I should export to Compressor. Tried but no sound. is it possible to burn to disc with 5.1 from FCPX?
I've been using FCP for around 10 years but FCPX is a bit of a learning curve. Even with FCP 7 never needed to use compressor as the movies I make are mainly for friends and family but now I have to have a 5.1 Dolby Digital soundtrack. I understand DVD Studio Pro did that but it's very complicated so please, even though well versed in the old FCP, treat me as a newbie on the new version.
Basically I have footage captured with my new Sony HDR- CX190 and have imported into FCPX. I have some audio I want to dub over the top which is in 5.1 AC3 but the first export only one clip came out, not everything in the timeline and no audio so sent to Compressior and it asked for settings so added them and Compressor said the sound was 5.1 surround and I processed and it burned to DVD but no sound!
You're all probably laughing as it's probably so simple I'm overlooking something that's most likely staring me in the face:
What I need to know is once I have all of my video clips, transitions and 5.1 sound in FCPX - how the **** do I get that onto a DVD or Blu Ray disc that will play all of the footage and in 5.1 Dolby Digital?
Any help will keep me from pulling my hair out!
Thanks
Dan

Be sure you have nothing selected in the timeline, especially ranges. If you have a range selected, only that range will export.
In 10.0.6/7 in the Share menu you can go out either SD DVD or Blu Ray DVD, and if the audio in the timeline is surround sound, the dics should encode that way. But be sure the timeline/project is set for surround sound.
If this is a Project timeline, go to the Project library, highlight the project, go to the Inspector, the bottom right is a button with a wrench icon. Click that and verify that "Audio Channels" is set to "Surround".

Dolby Digital 5.1 playback for output, now missing in iPad

Just last week i got new some movies from iTunes for playback on my iPad 2, including the HDTV. However since last 2 days i'm unable to find the 2 track option that appear during the usual playback on the iPad. There now seems to be no option where i select the DD 5.1 for output playback. (BTW the movies are encoded with Dolby Digital 5.1)

Can anyone please help me on this, if you guys can check is the 2-track option available while watching movies on iPad 2... or is it just me who is unable to find it despite these movies being encoded in DD 5.1

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.

Any cards support simultaneous dolby digital live and analog 2 channel output?

I am searching for a sound card that can output both dolby digital li've and 2-channel analog at the same time. I'm not sure if any of the Creative Labs sound cards can do this.
My Denon receiver outputs 5. in my main home theater room, but outputs only 2 channels to a separate room. I want to be able to play music in both rooms simultaneously. Unfortunately, the digital signal (which feeds the theater) is not converted to analog internally within the Denon receiver to output to the other room. The other room must receive an analog signal.
That is why I am looking for a sound card that can output both at the same time.
Does such a beast exist?

My computer updated to Widnows 8.1, now my sound blaster does not work. Everything else works (DVD, CD, Speakers, etc.) but I have no sound.
I'm not a tech person, a PC user and depend on my surround sound system.
I'd appreciate any help possible.
Thank you.

Dtt3500 and Audigy Gamer, digital output only 2 channel unless its D

Ok I recieved a response concerning my last comment but unfortunatly it did not answer my question at all. I have a DTT3500 and a sound blaster Audigy Gamer hooked up with the digital out to the /8 din adapter. I try the advanced 3d demo that came with the Audigy software and I only hear the front 2 channels, no center and no rears. The demo where you move the little icons and sound moves along with it. I have 5. activated in my windows control center along with audioHQ and digital out only is selected. my DTT3500 has 4./5. digital selected along with dolby digital/pcm audio and digital in. I am not getting the effect of multisurround at all. My center works and my rears work because playing music I can use all 5 speakers. When I use the analogue outputs I hear multisurround from the advanced 3d demo but my center doesnt work. The analogue setup sounds better but without a center channel its useless to me. Am I doing something wrong? I am using the adapter and digital DIN, what gives? The only reason I noticed I wasnt getting surround was while playing games nothing comes from behind you even on 5. games. The goldmine demo doesnt even work right, when the bird flys behind you it disappears but there is still sound from the rears. Analogue fixes this without a center but the manual and setup say to use the digital din. Do I just have a setting wrong? I would like to experiance the full capacity of multispeakers in my games.

Dennis,
With these speakers the connection that I would suggest would be to use the Digital out on the back of the sound card into the DIN Input on the DTT3500's. This will require a converter cable for /8'' Minidin to standard DIN which can be purchased from here:
http://us.creative.com/products/prod...0&product=0375
You will also need a standard DIN cable (one should have shipped with your DTT3500's).
This should give you 5. with digital output only enabled on the Audigy.

Digital Output Stopped Working

My new 1.66 Intel Core Duo Mini has been flawlessly passing digital audio to my receiver from VLC and EyeTV for close to a week. But I played a DVD for the first time today with Front Row and ran into a huge problem.
While there was no trouble playing Dolby Digital from Front Row, now I can't get any sound through the digital output outside of Front Row. VLC is silent and EyeTV needs to manually change over to "system sound output" for anything to get through. And then it's in stereo, despite Dolby Digital showing up as the soundtrack in EyeTV.
I combed this forum but couldn't find this specific problem. I saw someone recommended flashing the nvram as a possible solution to problems with the digital output but wanted to see if anyone had any other ideas.
1.66 Intel Core Duo 1GB RAM Mac OS X (10.4.6)

On a somewhat related issue: My Mac Mini 2007 won't output audio, via toslink mini adapter. It shows up in the Midi output as working and I see the red light from the cable. But when I put in a regular mini audio cable, and "move it around" in the headphone slot I get sound if it's just in the right place. Is this some sort of short in the headphone jack inside the Mini? Does this need to be replaced or is there an easier solution? Comments appreciated!
