Toggle Two Audio Tracks During Playback?

Is it possible to post a QuickTime movie to the Web with alternate soundtracks-- so the viewer chooses to view the video with either soundtrack #1 or soundtrack #-- but still sees the same (and only) video? I'm trying to save server space b/c this project will involve a number of videos and each will be posted in high and low bandwidth versions.
Read only if you're curious as to why I want to do this -- the reason for this is to provide #1 the standard audio track for the movie and #2 the alternate track that contains both the standard audio track and audio description. Audio description provides oral descriptions of the visual information during gaps in the dialogue/narration of the main program. Folks who are sighed would choose #1 and folks who are blind or have low vision would choose #2.
Thanks for sharing your wisdom.

There are some more complicated ways to solve the problem, but a very easy way would be to make two reference movies, and have both audio tracks as external movies. Your reference movie 1 would have the video only movie and sound 1 only movie inside it. The reference movie 2 would have the same external video only movie, and the second audio only movie.
I was worried that there might be something strange about the progressive download, like would all of the first track have to download before the second one started to download, so I tested it:

Don't try the first three links at first, just the second three links. You should find that any of the three starts to play as soon as it can, while still downloading. The first three links are the actual external files, and the second three links are tiny reference movies.
The one thing your users would give up would be the ability to change tracks in mid play (that can be done in other ways though), but for your application hopefully someone won't decide half way through that in fact they are poor sighted, and should have used the other link.
One other possible advantage of the reference movie approach is that the track that is currently not being heard does not have to be streamed, which would eat into the bandwidth.

Two audio tracks

I used imovie to create hd project. Looks great played through a blue ray player and regular dvd player. Looks great on 720p and 1080p televisions.
The issue is now with sound and two audio tracks. When played through built-in television speakers, the sound is balanced between two tracks (voice over vs. music.) When played through external, amplified speakers, the voice-over is too pronounced. I need to bump up the music.
Question: I can solve the problem by creating two versions, one for built-in speakers and one for amplified speakers. But I'm asking myself, what do I need to do to create a DVD whose sound will be the same on both types of audio systems?

2.5,
They sound great even after being burned in idvd, as long as the dvd is played on either a monitor with built-in speakers or on a television with built-ins.
The unbalance happens only when the dvd is played back through amplified speakers, and that's when the music suddenly takes a back seat to the voice over.
Other than an equalizer setting difference between the different playback systems, it's hard to explain why there should be a difference.
iDVD supports only uncompressed PCM audio and although the DV specification and DVD specification support more than 2 channels of audio, I have NEVER seem any indication that iDVD supports more than 2 channels of audio. Apple has never said much about audio in iDVD. (See http://en.wikipedia.org/wiki/DVD-Audio and http://en.wikipedia.org/wiki/DV )
DVD SP with Compressor DOES give you many audio choices (uncompressed PCM and compressed Dolby) as well as support for multiple audio channels.

How to burn a DVD with two audio track?

There is a projet with the original video and a second audio track with music. I want to burn a DVD with both audio tracks. When playing the DVD you should be able to select audio track 1 (the original sound) or audio track 2 (the music). With Adobe Encore DVD it was easy to configure the two audio tracks and burn the DVD. It is posible to do the same from Adobe Premier Elements 11?
Thanks,
Jordi

Welcome to the forum.
Unfortunately, PrE does not allow for supplemental Audio Tracks, when authoring.
I use Adobe Encore for this, but it is only available bundled with Premiere Pro. I do not know if some other, third party, full-featured authoring apps., like Sony's DVD Architect can do that, but I would suspect that they can. The specifications for DVD Architect should have that information, and as it's quite common in full-featured authoring apps., I anticipate that it has that capability.
If you do go with that program, our MOD, Steve Grisetti, has written a very good book on DVD Architect, and it's available at Muvipix.com.
Good luck,

QT H.264 files with two audio tracks. Quicktime plays 2nd track first. ***?

I've been experimenting with H.264 (AVC) and my DVDs. Using Handbrake, I ripped a DVD to MP4 (H.264) and including the director's commentary as the second track.
When I play the MP4 with Quicktime Player, it plays the director's commentary instead of the main soundtrack. VLC, however, correctly plays the first track (main movie audio track) and it allows me to select the second track via a menu.
To get Quicktime to play the proper track, I have to open "Movie Properties" and manually uncheck the second track. This was never a problem with DivX/XviD encoded files with two audio tracks; Quicktime Player correctly played the first track.
Why does Quicktime ignore the first audio track in MP4s (but not AVIs) and is there a way to correct this?

I do have QT Pro.
H.264 files are usually saved in a MP4 container. That's what Handbrake, ffpegX, and D-Vision create, anyway.
The "Choose Language" option is greyed out (unavailable) when I open this H.264 MP4 in Quicktime. If I try to change the settings in "Movie Properties," it says that I must save it with the .MOV file suffix.
It makes no sense to me that Quicktime Player can correctly identify the main audio soundtrack in a XviD file with an AVI container but not in a H.264 video with a MP4 container which Apple has been touting as the latest, greatest thing. Even VLC, an open source product still in beta, gets it right.

How to distinguish between two audio tracks on AppleTV?

Ripped movies with two audio tracks (AAC, 2-ch and AC3, 5.1) show both of the audio tracks as "English" on AppleTV. How do I know which one is the 2-ch or 5.1? Is there a way for Apple TV to show "English (Stereo)" and "English (Surround)"? I use Handbrake to rip DVDs, sometimes MP4Tools to convert audio, and Subler to tag them.

It is definitely possible to maintain separate sets of settings for two or more
publish connections of the same publish plug-in.
Without more detail on what exactly your code looks like, it is difficult to say what's not working right.
The contents of 'exportPresetFields' should be maintained on a per-connection basis.

Cutting two audio tracks in synchrony with video, question

I had to chop my movie in two because it did not fit on one DVD. This forum suggested that you make a complete second copy and delete the second half of one, and the first half of the other copy and burn your DVD with the respective halves. No problem with the first half, I deleted the video and had to go back and individually delete the audio tracks and everything stayed in synchrony. The problem arises when trying to delete the first half of the movie and not being able to use the play head to delete audio and video simultaneously. The audio of the first half of the movie is preserved, and if I delete the audio one track at a time it will shift the audio in relation to the video. I thought there would be a way of chopping off the video and audio tracks at the same point without the tedious task of trying to put everything back in sync "by hand". I have two audio tracks so it might be tricky to cut at the end of one audio track, without getting the other out of sync. Thanks for suggestions.
Mike

Hi Mike:
Perhaps the easiest way is to export the entire movie back to DV tape and then re-importing to imovie. That way, the entire movie is now combined into a "flattened" version. Meaning the audio and video are combined together into one video track, making it possible to split the final version in two.
Pain in the neck, but much easier that doing it one clip at a time.

Why video with two audio tracks imports like one track (main)?

Ok, lets face one simple thing that is incredibly stupid in Premiere CC:
- I make video with two audio tracks (screencast with system sounds and microphone, separated)
- Import it to Premiere CC and see only one audio track, system sounds!
- What should I do to see both of them?
- Why Sony Vegas don't make me to go to support forums and make them both visible without extra actoins?

Great first post!

You could have read the Premiere Manual or watched the Adobe TV Tutorials or gone to edit school instead ...

Two audio tracks in APT via Handbrake

Hey there...
I encoded one of my DVDs, using Handbrake.
Basically, I chose the AppleTV presets... except for the audio setup.
Here, I set up a second audio track (number one being english, with the second one being german).
So, Handbrake created a mp4 file as it was set up to.
I transferred that file to my ATV, using iTunes.
Now... everything works great. Except for the audio settings.
When I play that encoded movie in iTunes, I can choose either the one, or the other audio track as I like. On AppleTV however, it would just play using track 2 - which is weird for one.
I can't change the tracks, like you would be able to when you rented a movie in the Store...
Is there a special setting in Handbrake, that allows ATV to recognize that there are two audio tracks in the mp4? Or is there another workaround?
Thanks a bunch in advance!
Mark

sometimes i'd rather be. they have the better content in the US ITMS
What about music CDs? Are you allowed to convert them to mp3 and listen them on your iPod ?
yes, that's different.

Two Audio Tracks From Zoom H4n

I'm relatively new to video production, and I just got a Zoom h4n to get better audio for my videos shot with a dslr. I plugged a cheap dynamic microphone into it and recorded using mono mix (so I could use the mono track as a stereo track) When I loaded it up in Premiere and synced it to the video track, the audio from the h4n comes up as two audio tracks. If I mute one of the tracks, sound still comes out of both speakers. Can anyone explain what the second track is for?

Two tracks, meaning one clip on A1 and one on A2? I've never seen that from the H4n. Even 4 track mode creates two separate files that you'd have to add to two tracks individually

Beginner question: Two audio tracks become one - how to undo?

I know this surely is a beginners' problem, i hope for a quick reply anyway. I've imported material I had before logged with AVID Liquid, into Premiere CS4. In order to get video and audio together I had to put video and audio in a new sequence by hand. I then loaded this seqeunce into the source monitor to be able to cut my material (one video track, two audio tracks (one from a directional mic, which I don't always want)) from there. But when I paste a clip in my editing sequence I only get video plus ONE audio track in the stereo track. But I need both audio tracks because sometimes I'm going to delete one of them. So my question: How do I get video and BOTH audio tracks from one sequence to the other?
Thank you very much, you've had much patience with me with similiar questions.
Niklas

To do what you want, you won't be able to work with the media as a single clip. You'd have to go into the sequence with the video and two audio tracks, and pick out what you want from there instead of the Source monitor. Make your cuts, laso the clips you're using, then do a Cut/Paste from the main sequence into the edit sequence. Make sense?

When downloading video into FCP my two audio tracks are locked together.

When downloading HD video into FCP my two audio tracks are locked together. Channel one will not separate from channel two. Not good. One channel is my miked talent, the other abient. Any suggestions? I cannot find the problem. Sequence settings? Preference settings?
Help!

I think you mean "importing", not downloading.
Downloading is when you copy a file from an Internet server to your computer.
Channel one will not separate from channel two.
Any suggestions?
Select the two tracks and choose Modify > Stereo Pair
Or you can just use the keyboard shortcut option-L

You Tube videos that have two audio tracks?

When I view videos on my Mac there are two audio tracks with them. If I pause the video, an audio track is still heard, but I can't seem to control it. Any thoughts?

Vinay,
This is weird, but I don't know if it related to the Audio label issue. There seems to be no rhyme or reason to where the which audio track is used when I place an item into a video track. In this project I am using .mts files for my video and the audio has been going into Audio 2, except for the one marked in the image below, which is in Audio 3. When I tried to move it to Audio 2, it slipped up to Audio 1. This is throwing me off, because I have background music in Audio 3 and want a different audio level.

How to not overlap two audio tracks?

Hi, I use Adobe Premiere and I recently I had a problem with Action! (a video recording program) if you register the microphone and the stereo, Premiere overlaps the two audio and is not making me hear my microphone. I also tried to click the check mark on recording program (split audio tracks) but Premiere not divides. How can I create two audio tracks divided on the same record?

Are you saying that if you walk up to your Mac, iTunes suddenly opens?
At any rate, you should be using two different accounts on the Mac, each of you logging into your respective accounts, if you don't want common syncing.

Ripping the background using two audio tracks

I have two audio tracks for a show. One is in English the other in Japanese. Both have the exact same music and sound effect. But different voices. Is there a way I can perform an operation that leaves me with the background audio alone?

Do you know of any program that can do such a feat?
Audition does what's possible (see Durin's answer) as well as any software can. If you are dealing with mono files, then SuiteSpot's answer is the gospel truth - and that goes for all available and unavailable software.
Basically, you have to have some means of isolating a particular part of something in a unique way - this is how the Center Channel extractor works. The thing that this does is to say that a signal that's only in one location in a stereo field can be isolated - just by its position, nothing else. So if you have a mono voice superimposed on a stereo background then the mono voice can be isolated. But because it's by position, then anything else at the same spatial spot will also be eliminated - and almost inevitably this will mean that part of your music track will be extracted as well, so it's not going to be perfect.
Please, just don't believe everything you hear on CSI (or any similar crime show). What they purport to be able to do forensically simply isn't possible in the way they appear to claim.
