Audio tracks vanish on export

Relative newbie here with a bit of a puzzler on my hands. Recently, when I try to export a video from my project (H.264 codec, 720x480, approx 20 mins in length with estimated file size of about 460 mb) the video seems to export just fine, no error messages or anything. However, the file size is only listed as being 392 mb. Sure enough, when I check the exported video there's something missing: my entire second audio track. The audio in track 1 appears to have come out without a hitch and it's perfectly synced and everything but the audio on track 2 doesn't appear to have made it. I've checked around my project settings and track 2 isn't muted or anything like that and I can hear the audio just fine when I preview in the timeline but for some reason it just disappears on export. I've never had this problem before and I can't seem to find anyone else on the internet who's had it either.
Anyway, this is only now showing up as I'm working on the last section of a lengthy project so this is unbelievably annoying. If anyone can help I'd be very appreciative.

Okay, update: I've managed to determine that the problem is not with track 2 but with that one particular audio file. Here's the rub though: I import that exact same audio file into a new project and it exports just fine. Also, I've been using that same file for the past 3 weeks with no issues at all and I don't recall ever changing my settings. So since the audio file itself clearly isn't corrupted and simply doesn't appear to export correctly my new question is: where can I look and what settings can I adjust so that the file exports correctly in that same project again? I could theoretically salvage some of my work but it would take hours of editing the same footage in a new project and I don't really want to do that.

How do I control the number of audio tracks in an exported QT movie?

I am at a loss. I have 59.94 fps DVCProHD files that I want to trim and to export in the same format. The original clips have two tracks of audio, but the exported tracks have eight tracks of audio. I normally use an 8-track audio card, but nothing I do seems to prevent the 8-track export: I have selected "stereo downmix" in the audio mixer tool and set the audio playback device to "Built-in Audio," to no avail. I want the exported files to have the same two audio tracks as the original, not two plus an empty six. There seem to be no controls that allow me to specify this. Can anyone explain to me what is going on and how to change it?
Thanks.

Hello Robert,
It might be that your sequence is set to output 8 channels. try this...
Go to Sequence>Setting> and go to the 'Audio Outputs' tab. Here, change the 'Outputs' to 2.
You might also want to check the track-assign buttons on the timeline, ctrl+click on the auto assign square (just to the right of the little padlocks) and go to the Audio Outputs. Check that each track is assigned to 1&2.

Unwanted raw audio track in MP4 export - how to avoid?

Dear everyone,
I recently had some trouble with audio in an iMovie project and exported it to GarageBand, where I did all the audio post production (= three additional audio tracks with voice over, music etc).
Everything went fine, and I exported the GarageBand project using "Share" "Export Movie to Disc" using the "Full Quality" settings to retain the original movie quality.
Now here's the odd thing:
The resulting MP4 file has two soundtracks. Soundtrack 1 is the original, uncompressed sound from the movie's DV clips, soundtrack 2 is the mixdown audio track from GarageBand.
I have tried several playback devices (e.g. a Samsung TV), and it will default to the original track, which I do not want.
Long story short:
How do I get rid of the unwanted original audio track in the MP4 file exported from GarageBand? Can I get rid of it right in GarageBand, or would I need QuickTime Pro or another tool to do it later?
(Again, to clarify: The exported MP4 has two separate audio tracks (shown e.g. as "English 1", "English 2" on a USC-capable TV set. I need to get rif od the raw audio track 1.)
Thanks.

Even the most verbose description has room for misunderstandings.
So, to clarify:
I do actually use the original audio in the GarageBand project. In some clips, it is muted, in some, I add fades.
This is all fine and dandy and part of the mixed, mastered audio - which is exactly as I want it when exporting said MP4/MOV file for example to iDVD. The DVD has the proper soundtrack, and only that.
The problem is that in addition to this correct, GB-mastered audio, I get the totally raw audio as a separate audio track, which is per default played by a Samsung TV's internal MP4 playback engine or a WD TV.
(And I mean "audio track" in the context of the MP4 file, not as in "a GarageBand audio track".)
I hope that clarifies the issue.
Thanks

Adding several audio tracks to quicktime export setting .

I am trying to add several tracks of music to a quicktime movie , created using the export option from iPhoto, but it will only play one track even though I selected 4 tracks and made them default .
Any genius out there ?
Thank you

Are any of these tracks DRM tracks from the iTunes store? That will certainly kill the process. Others have reported similar issues but there's not been a one size fits all fix.
There is a workaround but requires a little extra work. Join the 4 tracks into one new track with either Garageband or another audio editor like the free Audacity. Then add the new track to iTunes and into the slideshow.
You can search this forum for "slideshow music" to get other posts on the subject and some possible solutions to try.

Adding multiple audio tracks to a multicam file

I am editing a multi cam production- and have 8 different audio tracks- separate from the movie files. I have made a multi cam file but any ideas on how to add all 8 tracks of audio to this multi cam file- then edit- and then question no. 2: how do I then export all edited audio tracks separately for my sound engineer to mix them? Thanks a lot

Hi Tom- thanks for your response I´m not quite sure if you get me right... I have made a multicam file- consisting of 4 cameras- and now I want to add 8 audio tracks that are not connected to any of the cameras- but that were recorded seperately- and have all these 8 tracks lying underneath all the camera angles- being synced up with the cameras internal mics- but I want to edit the 8 audio tracks and finally export them. Thanks

I've been using Ringtone Maker to add ringtones to my iPhone. The app is now telling me my music I bought from the iTunes store is not exportable. I downloaded a new app called Ringer and it says my song "has no audio tracks". What am I doing wrong?

never mind. i think it just makes you review the information -- it looks like you have to click through everything.

How can I export an audio track with just the effect signal without the audio?

I want to export dry audio tracks and their effects signals as separate tracks. For instance a track with a reverbed snare would be one track with the dry snare and one with just the reverb.
I know from people who use Reason that it's just a box you need to tick, but I'm struggling to find out how to do it in Logic. Surely it must be a way?

I don't remember Reason being that straight forward, but the obvious way to go, is to mute all sends and bounce.
Then solo the reverb channel, in aux, checking it isn't shared by other sources, and bounce. You should have a dry and a reverbed signal, at your convenience.

How can I export an audio track

I have made an audio track with three songs in GB and now I want to export it and use it as a track for a Keynote slideshow.
How can I export it as AAC or similar?

Media Encoder CS6 Not Exporting all Audio Tracks From Premiere

I'm working with DSLR footage, 2 Channels of .WAV audio from an exernal recorder (H4N), and a 1 channel .WAV Music track. 3 Channels total of .Wav audio.
I can export from Premiere Pro CS6 to H.264 just fine, but if I try to send it to Media Encoder, it only track 3, which has the music.
I can't figure out this issue, and haven't found an answer on any forums. This problem effectively makes Media Encoder useless to me, so I would prefer it to be solved, rather than find a work around.
Thanks in advance for your help!
Mark

I'm having the same problem. But even worst.
For the test, I take a 10 min .mov or mp4 file, simply modify the "scale", and hit the export.
a 10 min file is taking 4 hours to render.
This is on a:
2012 MacBookPro i7 2.3Ghz, 16 GB 1600 DDR3, SSD disk. - Mac OSX 10.7.5
and a:
2011 iMac i7 3.7Ghz, 16 GB 1333 Mhz, 7200 RPM HD - Mac OSX 10.7.5
The CPU stays at 90% idle the whole time.
I know this is an old thread, but maybe someone could give me a hand.

Please help. My audio track is too low after exporting movie made with Premiere Pro to YouTube.

Hello. My crew and I recently completed post-production on an independent film. We used Adobe Premiere Pro 5.0 for video and audio editing. We had a very low budget for production, so we didn't have the best audio equipment to record sound with. So in editing, we had to do quite a bit of sound mixing to minimize background/ambient noise and interferences/distortions caused by large electrical appliances in some indoor scenes, such as taverns and cafes. We managed to clean up the audio, and the audio ultimately sounded great. However, when we exported the film to YouTube, the entire audio track sounded low. To hear the film at an adequate level on YouTube, the volume has to be turned all the way up. I'm wondering what can be done to export the film to YouTube and maintain strong, optimal audio volume/quality. Any help would be greatly appreciated. Thank you and take care.

As Jeff of Safeharbor noted, you really need to check the audio meters in Prpro with your "final" project. I found that I could have a sound level that played fine on my computer, but ... on exporting to a DVD ... was way low and required a very high setting on any other computer or a tv to be able to hear. I hadn't actually looked at the audio meters. On checking them ... yeah, the peak was down about -18, the main content of the talking-heads was below that. After raising it with PrPro's audio tools, the sound was fine.
I'd bet your sound is showing low on the meters ...

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 do you export separate audio tracks for Pro Tools?

I need to give separate audio tracks to my sound mixer but am confused on how to do so in FCP X.
So far I've:
Set the dialogue roles and stems for each character
Then I went into Master File>Settings
Selected:
"Format: Audio Only"
"Audio File Format: Wav File"
"Roles as: Audio only as separate files"
"Dialogue"
Sara
"Stereo"
And when I export and listen back to the wav file, there is either no audio or I hear select dialogue.
The only thing I can think of that I am doing wrong, is that each characters dialogue is not on the same track like the picture below. The tracks highlighted is of one character's dialogue that I am trying to export onto one linear track to export into Pro Tools.
Can tracks be assigned in FCP X? Or is there a crucial step that I am forgetting tthat explains why the audio for each character is not being exported.
Thanks!

If you're dumping audio for ProTools, you should be able to export XML for use in PT. Haven't done it myself, but the option's been there for a while now. You should be able to find instructions easily.
If you want to stick with making Roles work, I suggest making sure the roles are assigned properly to each clip. Kind of a super pain in the neck, to go one by one, but ... that's the way. There are key commands for the three default roles, but if you've created custom ones then it's more time consuming. Is that 'Sara' one a custom Role that you've created?
My only thought is you have compound audio clips there. Maybe go in and set the roles on the individual files inside the compound clips. Dunno...
The visual organization shouldn't matter (one track above another). That's the X way.
((In your picture, you say you have some files selected. When I select, I get a yellow border; yours are light green and dark green. What is that?))

Exporting a project with multiple audio tracks changes the loudness level regardless of export format

I recently had to submit a TVC and discovered that premiere was changing the loudness level after export, when the TVC failed the quality check.
I checked the audio loudness of other formats that I had exported and the same thing had happened the audio loudness, it had changed.
After a bit of troubleshooting I found a workaround. I mixdown all of the tracks in adobe audtion to one track and then imported it into premeire.
Once I did this the audio loudness was not changed after exporting.
Workflow for when it didn't work.
I used edit in adobe audtion for the audio tracks from premiere.
Matched the audio to the loudness level I wanted, and then saved each track.
Export from premiere.
To Check Audio Loudness
Bring in exported file into new premiere project
Edit the audio in adobe audtion.
Drag the audio file into match audio to check loudness level.
I am using
Adobe Premiere Pro CC v8.1
Windows 7 on PC
Please fix this adobe.

What did your Broadcast Quality Control pick up on?
Audio Levels and Loudness are two different things in this regard.

Urgent help!! In 'export audio to movie' the final option to disable the original audio has disappeared. I am no longer allowed to deselect the audio tracks. Any ideas why Logic has stopped this?

Greeting all
I'm creating a movie with a new music track and follow the appropriate steps as in the manual:
Choose format options for the bounced audio file, and click OK.
In the dialog that appears, enter a name and target folder for the movie, and click Save.Another dialog opens, allowing you to choose which of the original movie’s audio tracks should be used in the new movie.
Select the audio track that you want to retain in the new movie, and click OK.
The QuickTime movie is exported to the selected folder; it contains all selected audio tracks, plus the part of your project that is encompassed by the start and end points of the QuickTime movie.
However, this final dialog option 'select the audio tracks of movie to keep in new movie' has disappeared!!! For some reason Logic goes straight to bouncing without the offer to remove the original audio. My final movie ends up with both sets of audios. Any ideas please???
Best
Juan

It is still there and Logic did not remove it.
Did you do some trouble shooting.
Try to load a different video (with different codec) to see if it is video file related
Try a new (empty) project to see if it is project related
Try to remove Logic preferences (move the original back if this wasn't the problem because the file contains other info you might not want to lose)
Hope that helps

We can not see your computer, your settings or even know what your source files are because we are not in the same room as you are!
We cant see what you are doing wrong ...so you will have to tell us a lot more and show us some screen grabs of your settings.
