Q: Audio on keynote exported quicktime videos cuts out at 50 seconds?

Follow up on my last followup. I had two Keynote 6.5 presentations that displayed the audio problem we have been discussing. The first of them somehow "fixed" itself and I was able to hear audio to the end in the "Play Recorded Slideshow" mode and export the slides with audio to Quicktime. On 11/20/2014, I upgraded my mid-2011 MBA to Yosemite 10.10.1. Today, 11/22/2014, I played the remaining problem presentation in Keynote 6.5 and it seems to have "fixed" itself as well. I was able to hear audio to the end in the "Play Recorded Slideshow" mode and export the slides with audio to Quicktime.

I don't know if this had anything to do with the Yosemite upgrade or not. My first problem KN file fixed itself before the upgrade. The second one afterward. When I upgrade the OS, I always clone my machine first using SuperDuper! and fix permissions before cloning.

In any case, the audio was obviously recorded for my entire presentations and this is a playback issue.

Happy to share one of my files that suffers this problem.  We need this problem fixed ASAP!!!

This solution worked for me!  Thanks.

Same here.  No sound after 50 or so seconds, but when I export to 09 the audio works.

I found this discussion because I was having a similar problem. I created a "promotional video" in Keynote. I recorded a narration and music background track in Garageband, which I exported to an .mp3 file. I then selected my soundtrack (.mp3) in Keynote. To get the slides' transitions to sync with the soundtrack, I clicked the "Record" button in Keynote. I clicked the mic mute button right before I clicked the round red "record" button so it wouldn't record any background noise.

When I exported it to "Quicktime", I realized the video was missing the audio. After hours of agonizing over the problem, trying all sorts of things, I contacted Apple support (I still had a few days left of free Apple Care ). The help agents were very friendly and helpful, and they helped me narrow down the issue. I am really excited to have the problem solved!

My problem was muting the mic when I recorded the timing. I guess by muting the mic, I was also muting the soundtrack too. If you want to record the timings without recording background noise (and the clicks of your keyboard buttons ) go to your "System Preferences"-->"Sound"-->"Input" and turn your "Input Volume" (the mic icon) all the way down.

THE KEY IS THIS: DO NOT MUTE YOUR MIC INSIDE KEYNOTE IF YOU WANT AUDIO OUTPUT TO YOUR QUICKTIME VIDEO. This completely solved my problem. Hope it helps you!

If this doesn't help, I highly recommend calling up Apple Support. Click here for contact information. If you have not activated your complementary, free "Apple Care" (might be 30 days-90 days), now's a good time to do that and take advantage of the opportunity to get your problem solved. If you already activated it and it's expired, you can still call them up and talk to an actual person (). They will listen to your problem, and tell you if you need to pay the $29 fee to continue forward towards a solution.

This problem has NOT been fixed.  Some of the proposed work arounds do not seem to work.   This should be an obvious address, folks.  Recorded sound STOPS are approx 50 seconds.  "play recorded slideshow" in KN and it costs off, so not an export issue. Yosemite 10.10.1 KN 6.5

Did you read my post right above? I am curious if it makes sense, and if it at all helps or not.

ITM78 - I did NOT click on the mute button on the recording.  I DID try your suggestion to turn down the input, and I DO have a soundtrack.  Audio still cots off at around 50 sec.

This should be an obvious address, Apple folks. This issue raised some time ago.

Recorded sound STOPS at approx 50 seconds.  "play recorded slideshow" in KN and it costs off, so it is not an export issue or a QT player issue.

Per itm78, I tried made sure not to click mute on the recording (I do use soundtrack).  Also turned down input.

Audio cuts off around 50 sec - KN player (of recorded only, DOES play in runtime render) and export has cut.

Issue seems the recording process or the artifact/file/package that is created in the recording.

MacBook Air - Yosemite 10.10.1 KN 6.5

I have identically the same problem using KN 6.5 under OSX 10.10.1 using an iMac. I tried the suggestions on this thread, but the problem remains. The file I'm working on is about 8:30 in length, has only 16 slides with recorded voice over (that seemed to go well), but audio fails during playback inside KN  at about 50 seconds +/- with the same thing happening when I export the file to Quicktime(i.e., no audio). The KN file size shows 16.2 MB, so it is likely that the audio is recorded. I just can't get at it either with KN or with an export.

Does anyone know the status of a fix and whether Apple is aggressively addressing a fix?

Check what TarqTeles said about packaging on page 1 about packaging. I wonder if this helped solve my problem.

Tarq - excellent - this solved the issue.  And thanks to itm78 as well.

I found a workaround by changing to format type of the Keynote I was trying to export back to "package"

Just go to File > Advanced > Change File Type and change from "Single File" to "Package"

Great! I wonder if this would solve the issue for everyone in this discussion. Everyone with this issue should give TarqTele's tip a try (Just go to File > Advanced > Change File Type and change from "Single File" to "Package"

Tried the suggestion:

File > Advanced > Change File Type and change from "Single File" to "Package"

It works!  Both on KN replay and when exported to a quicktime file. Full audio throughout.

Many thanks for the advice.
