Can AppleTV play multiple audio tracks in a movie?

I recently discovered (pretty much by accident) that iTunes and the iPhone supports multiple audio tracks in a single m4v video file. So I've started ripping my DVDs using Handbrake with both the main audio and the commentary track.
In iTunes and my iPhone I can swop between the two at will, but I cannot find any information on how or if it's possible to switch audio tracks on the AppleTV. Does anybody know?
I'm using an AppleTV 2 with up to date software and iTunes 7.6.2 set up to sync.

this same question was asked in the last 2 days (and may even be still listed on page 1).

however, the answer is no.

How to play multiple audio tracks simultaneously?

Hi there,
I am having problem with playing multiple audio tracks. I want to play 2 or more audio tracks at exact time (without delay) - is it possible? how can it be done?

So, essentially, you're trying to take a recording of say, a singer and a guitar player, and end up with the singer in one file and the guitar in the other. Got it.
[http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/solutions/Merge.html]
That sample will merge multiple input files into a single file. Because you want to play the files together rather than save them, just take the sample and strip out all of the DataSink stuff, and add the following line right after the Processor "outputProcessor" is realized...
outputProcessor.setContentDescriptor(null);
So, it'll make the following revision to the code:
     // Create the output processor
     ProcessorModel outputPM = new MyPMOut(merger);
     try {
         outputProcessor = Manager.createRealizedProcessor(outputPM);
                    outputProcessor.setContentDescriptor(null);
         outputDataSource = outputProcessor.getDataOutput();
     } catch (Exception exc) {
         System.err.println("Failed to create output processor: " + exc);
         System.exit(-1);
     }That'll make the outputProcessor play the file, as if it was a Player object. You won't have any visual controls, but if you need visual controls, then don't do that, and just create a Player object to play the outputDataSource.

Movie Playing multiple audio tracks & echoing

I have a movie that is in a symbol that i want to play after a set amount of time by using setInterval. The function works - but when it shows the symbol and plays - it plays multiple audio tracks at the same time - sounding like an echo and or a 1-2 second delay on the same audio track. It also seems the audio starts playing on the main root without actually triggering the playhead of the video symbol.
Following is the code i am using for both timer and the video. Any pointers?
// interval
         var timer = setInterval(onTimer,10000);
         var mysymbol = sym.getSymbol("btn1_video");
         // function
         function onTimer() {
            // clear last interval
            clearInterval(timer);
            // action
            sym.$("btn1_video").show();
//and on on the movie symbol timeline trigger:
var vid = $("<video width='818' height='460' autoplay='autoplay' preload='auto' controls='controls' id='videoID'>" +
"<source src='video/testvideo.m4v' type='video/mp4' />" +
    "<source src='video/testvideo.webm' type='video/webm' />" +
   "<source src='video/testvideo.ogg' type='video/ogg' />" +
   "This browser is not compatible with HTML 5" +
"</video>");
sym.$("btn1_video").append(vid);

You identified the problem. I thought that you had to highlight the first song to get the playlist going, but all that does is make the first song repeat itself. Thanks for the guidance.

Adobe Premier Pro CS4 can't play mpg audio track - any fix?

Hello
I need some help about Premier Pro CS4:
I'm using Mac OS X 10.5.8 and adobe premier CS4
I Imported a video file .mpg to timeline, but the audio track is'nt vilible or playable, it's just like it doesn't have any just like.
The file came from DVD, after demultiplex, using Vob2Mpg (open source software), this operation produced a file with mpg extension - the file that does'nt work.
I looked in the web and some say that it works on adobe premier CS3
Anything that can fix this, any solution?

Snow Leopard iTunes 10.5 will not play multiple video tracks in QuickTime .MOV files

I recently discovered that Snow Leopard iTunes version 10.5 won't play multiple video tracks in a QuickTime .MOV file.
Both video tracks appear and play correctly when playing the file in:
- QuickTime Player 10 or QuickTime Player 7.7 on the same Snow Leopard machine
- iTunes 10.3.1 on another Snow Leopard machine
- iTunes 10.5 on Leopard or Windows 7
So I think the problem is iTunes 10.5 on Snow Leopard (although I haven't been able to test iTunes 10.4).
First test file is two 640x480 video tracks side-by-side (total dimensions 1280x480):
http://160.94.17.23/demo/two-video-tracks-1280x480.mov
All I see is the first (left) video track, and not the right one. iTunes "Get Info" command incorrectly reports the video dimensions of the file as 640x480.
Second test file is two 640x480 video tracks played one after another (duration of 10 seconds each):
http://160.94.17.23/demo/two-video-tracks-640x480.mov
All I see is the first video track, and although it reports the correct file duration (20 seconds), the second video track never appears -- it simply freezes on the final frame of the first video track for the last 10 seconds.
Anyone else see similar behavior? Unless I'm missing something, I suppose I should submit this as a bug to Apple.

I have the same problem, i tried re-installing, converting it to AVC H264 but none seems to work so far

Can Flash play multiple audio and video files at the same time?

Hello,
I would like to create a web-based client/application that
can play multiple a/v files or stream multiple a/v files at same
time. Is this possible with Flash, without the use of RTMP? If yes,
can you please provide an example. Thanks in advance.
Regards,
Nilang

You never edit within a clip. The purpose of opening a clip is to make sync adjustments, audio equalization, color correction, stabilization, things that you might want do overall to the master clip before you edit it. You edit the portion of the clip you want from the browser into a project. There is really very seldom any need to open a clip into the timeline.

[SOLVED] Single audio source (can't play multiple audio sources)

Hi,
I have been having this problem in my arch laptop for a long time until I decided to put an end to it. I am using Gnome 3 and pulseaudio, and whenever an app "grabs" the audio, it won't release it, meaning no other apps can play sound. Even when one firefox tab grabs the audio (for instance, Gtalk notifications, youtube videos...) no other tabs can play it. I can avoid the problem if I reload the tab, or close the app.
Is it a weird problem? Is it related to pulseaudio? I haven't found information related to this.
Thank you.

Multiple audio tracks playing at the same time?

Does the Adobe Elements 12 allow us to have mulitple audio tracks playing at the same time? Is there a limit to the number of tracks?
Thanks!

Hi Jennifer3211,
Yes you can play multiple audio tracks simultaneously. The maximum no. of audio tracks can be 99.
Thanks

Adding Multiple audio tracks

Hi people.
How can I add multiple Audio tracks on a video which then can be switched on a DVD remote control?
Please help.
thanks in advance.
J.

jagthandi,
I agree with you on the separate purchase of Encore. It's a great authoring program. Until CS3, it was sold as a stand-alone, though was also included in the CS2 Production Studio, which is how I came by it. Adobe began integrating it more and more closely to Premiere Pro, so that became more of a "module," than a stand-alone. As of CS3 it only came bundled with P-Pro. Good on one hand, but not so good, on the other. Having used it for many years now, I would be loathe to use any other authoring application.
It seems that Sony has done similar with their DVD Architect Pro, only bundling it with Vegas Pro.
What this means is that there are now few full-featured authoring applications in an affordable price range. DVD Studio Pro being one of the few, and its interface is not as clean as Encore's. It offers potentially more power, but you have to do some basic programming to use that power. At the top of the list is Sonic Scenarist, but at around US$50K, complete, it's not really an option. Also, its interface takes years to learn.
So very glad that I have Encore2. I will likely never part with that program, as it does 99% of what I would ever want from an authoring application. That last 1% can usually be done with some creative workarounds.

Can quicktime play an video track with multiple alternate audio tracks?

Hi,
If I have a video track with multiple alternate audio tracks (say different languages), can a user select the audio track of his choice and play in Quick time?
Thanks,
Apurva

Does quick time/ safari have this capability?
QT (i.e., the QT structure embeded in current Mac OS/device IOS versions) has the ability to switch between alternative audio tracks assuming the file is properly encoded and the compression format is supported. QT 7, QT X, iTunes, and similar app player GUIs can switch between such tracks during playback but the QT plug-in cannot. In a similar manner, devices like TV can switch between such tracks but an iPhone cannot just as an iPhone can select "Chapters" but the QT browser plug-in cannot but an iPhone file programmed with both chapters and alternate audio tracks can be played back through a TV device and access both chapters and alternative audio tracks.
What I want to use is one video track with alternate audio tracks in a set level manifest and play this using HTTP Live streaming. I'm using the manifest mentioned here :
http://tools.ietf.org/html/draft-pantos-http-live-streaming-07#section-8.7
Since I do not use playlists, I am not familiar with the approach in your example. If I want alternate audio and/or video tracks, I create standalone video files with these features built in. Nor do I use RTSP if that is what you mean by "live streaming" of content. If I want to "stream" the content, I use "Fast Start" files programmed to open in the QT player app which supports these features or create reference or QT Media Link files that do the same thing.
As you mentioned, Safari on my iPhone is playing the default/first alternate audio track mentioned but not giving an option to switch tracks.
Neither Safari nor the Video app GUIs on your iPhone have a built in switching option. The only way to switch to alternate audio tracks is to do so with QT 7 Pro or possibly iTunes before loading or streaming the video file. (Am still speaking about a standalone file here and not a programmed playlist/RTSP switch.)
However Quick time on my Mac machine only plays the audio with the the video stream and not the alternate audio track.
The QT player app GUI only switches between tracks that are stored as part of the standalone file. Basically, QT files may contain up to 99 individual data tracks. In alternative audio videos, multiple audio tracks are added to the file by an editor like QT 7 Pro but only one track is designated as "active." All other tracks are designated as "inactive." The QT player GUI allows the viewer to select which audio track he or she wants to hear and then turns off the current audio track and turns on the selected audio track. Otherwise all active tracks would play simultaneously.
Is there a way to switch tracks on my iPhone on Safari?
As previously noted, the default track can be manually changed by QT 7 Pro or, I believe, iTunes (used to have this capability) before actually loading or streaming content.
Does quicktime have this capability?
As far as I know, only with regard to stand alone files programmed with multiple alternate tracks. I am not a HTML, HTML5, or Java programmer so I assume there may be web alternatives here but they would be beyond the scope of my expertise.
Do you know any free player that can do this?
Again, I don't use either playlists or RTSP so I've never had a need to look for/use alternative players that might meet your needs. I simply find it easier to build files that work correctly in current player app/device GUIs already having these capabilities.
Or the very last option, can I build a player to do this? If yes can you suggest where/how I start?
Once again, I assume this might be possible but not part of my experience since, for my part, easier work flows are available.

Multiclips and multiple audio tracks playing at the same time

I've only just taken delivery of my first ever mac (only ever used PC) with FCP, and I'm loving it already! Done lots of reading and viewing of video etc etc, and it's not as daunting as I thought it might be. I have one question the books don't seem to answer, and I can only find one reference to this on this site, with no definitive response. FCP5 probably doesn't work this way, but just in case someone knows different......
I film and edit motorsport (karting) programmes for television in the UK, using multiple cameras. I usually lay all the video and audio tracks on the timeline, (synched) lock the audio for each (as it is engine noise, and I want it playing without abrupt changes at cuts as each kart passes each camera, whether in shot or not) then cut the video tracks and delete those video segments not required.
The most exciting aspect of FCP5 for me is the multiclip editing facility, which I have found very easy to learn and is going to save me hours of work! However, I want to know if there is a way of having each audio track from each camera used in the multiclip laid down on the timeline when you import the multiclip to the timeline from the viewer, in order that I can play each audio track from each of the cameras at the same time.
I know how to cut from angle to angle, leaving the audio from the selected angle as the one audio track playing, but I want all of the tracks to appear in the timeline and play at the same time. I know there's a bit of a workaround by locking the video and importing each audio track from each clip independently, but if you do have to re-synch one of the multiclips, this means the audio is not then synched with the original clip, which will have had an in point set before being imported in as part of a multiclip.
I can understand why you might want to keep audio from one camera only playing over the whole multiclip, or to switch between audio from each, but in my case I prefer all audio to play at the same time. The workaround is still do-able for me as I'm only talking about engine notes, which if they are a few frames out is not very noticeable at all, but I would like to know if I'm right in thinking I cannot do it the way I would like to?
Wish I'd used FCP from the start, but glad I've got it now.....especially with the 30 inch screen! It's 4.40am, been going over 19 hours straight and I'm still making comments like...."WOW, that's brilliant"...every half hour!

How can I edit imported audio track? After selecting and deleting region and joining remaining parts, it keeps playing the track with the deleted part! What am I doing wrong?

After selecting and deleting region, and joining remaining parts, it keeps playing the track with the deleted region!
What am I doing wrong?
How exactly are you doing this?
When I cut out a part of an audio region, then drag the remaining parts together, so they are touching, the track will skip the cut out section when playing the file. Also, if I select the remaining parts of the region and use the command "Edit > join regions". This will create a new audio file with the cut out part deleted.
You should see this prompt, when you are joining the regions:

CS3 Multicam Multiple Audio tracks, only audio from Cam 1 plays

In Premiere CS3 I have 4 Cam edit I have all tracks, video and audio on main timeline. I also have audio from a DAT recorder on a seperate audio track. Everything is sync'd. I created my multicam edit sequence and nested my edit sequence into it. How can I get the audio track from the DAT to work on the nested sequence? It seems that the only audio I hear is that from Camera 1. What I would like to have is the audio from camera 3 AND the DAT recording. It is a live music performance and I want the audio captured from the House mixer which is really clean but I would also like to have the audio from oner of the cameras for ambient house sound. You know, sing alongs, yelling and clapping. After all, it IS a IVE performance. Any suggestions?
Greg

Hi,
See also my posting on the issue "Multicam is extrmely slow".
In short:
Make a timeline with all sources and sync them all, make sure everything is ok.
Then make a copy of this timeline and disable all video except one (for reference). Name it "Sound"
Move all soundtracks of your first timeline down to free soundtrack one.
Drag the sound track of "Sound" to track 1 of the first timeline. Then go on with the normal method for multicam (new timeline "Target", drag Source on it and enable multicam)
Any adjustmentsa needed in the sound can now be done in one place; Time line "Sound"
For performance reasons it might me better to drag the sound track of "Sound" directly to "Target" and disable soundtrack 1 (from Source). Disadvantage then is that removing parts from this multicam timeline needs the same removal from the soundtrack (on 2).
Hmmm, now I am writing this, can I unlink in Target the video and soundtrack and link soundtrack 2 to videotrack 1? Have to try that.

Is it possible to retain multiple audio tracks when exporting?

While ripping my DVD collection, I've wanted to add a purchased RiffTrax (see www.riftrax.com) to the movie as another audio track. I've been successful, but it took the following steps:
1. Encode the movie using Handbrake, open the resulting m4v file in Quicktime Pro
2. Also in Quicktime Pro, open the Rifftrax aac file I created and add it as another audio track in the m4v
3. Save the m4v as a Quicktime mov file
4. Use Handbrake again to encode the mov file into an m4v file, including my added audio track
The reason I have to do step 4 is because if I were to export an m4v file directly from Quicktime Pro, it would compress all of the audio tracks into a single audio track. It would save a lot of time if Quicktime could export multiple audio tracks, at least when exporting to formats that can handle them. Does anyone know if this is possible?
BTW, if anyone wants more details into how I create the RiffTrax aac, just ask.
- Jake

I've answered my own question, it was a lot easier than I thought. After the first encoding by Handbrake, there's really no difference between calling it a mov file or m4v file. I can change the file extension at will and there's no need to do an export that mashes the audio tracks. It's only AppleTV that needs to see the m4v file extension, Quicktime and iTunes doesn't seem to care one way or the other.
Thanks for letting me think out loud.

How to quiet multiple audio tracks

I have 6 seperate video tracks (multiple angels of the same event). I used the suggestions given to me before on how to synch up all the footage. My problem is I can't figure out how to silence all but one video track so I can mark where the synch spot is (an air horn). When I click the green button next to the audio track, it unrenders the audio, so that isn't an option. I only need the audio to mark the synch spots, then I can delete it as I have a tape of just the audio through the PA system. Any suggestions?

I think rendering the audio has to do with the way I import to FCE. This is how I bring video into FCE because it seems to be the only way I can get it to work. I run my video camera through a digital coverter which runs a firewire into my Mac. I then import the video into imovie. After that is done, I do a drag and drop of the imovie into FCE. I have to render the audio because it just beeps if I don't when I play it back in FCE. I tried using the video capture in FCE but it keeps telling me it is unable to capture (my gues is the cameras are too old and the digital converter in not compatable with FCE or Mac). So once the video and audio footage is in FCE, if I click the green button on the left hand side, my rendered audio becomes a red line. However, I can click the same button on the upper video portion, and it drops the video out so I can see video clips on the lower levels and not just the first one on top. So that's why I render the audio. I can see all twelve audio tracks already. Tom- would making the change you suggest still help? Great book by the way also.
