Loses sound on imovie

I made an imovie from my new camcorder and half way through I lose sound on the DVD. I have sound on the mac when I playing it from imovie- then I send it to idvd and burn it and play it back, halfway through there is no sound. Anyone have any ideas?

Opps~ Still not fixed.

Why do I lose sound when I try to make a dvd from imovie to idvd. The sound is all there in iMovie, but when I make my dvd, I have sound for about 3-4 minutes and then its gone.

I have made a 1 hour 30 minute dvd in IMOVIE. The video and the sound are perfect. However, when I make it into a dvd on IDVD, I lose sound after 3 or 4 minutes. Any Suggestions?

Hey MichiganMan32,
I found an article that looks like it applies to that audio issue you're experiencing. Check out the following troubleshooting steps here:
Resolution
Make sure the audio track has not been muted in the timeline.
Switch to timeline view by clicking the clock button in the iMovie window.
There are three checkboxes on the right side of the iMovie window underneath the sound icon. These checkboxes correspond to the video track and two additional audio tracks. Make sure all three tracks are selected. Any deselected tracks are muted.
If you are using iMovie 3 or later, check the "Edit Volume" option to see if it is selected. If so, make sure the volume of the affected video clips is not set to its lowest level, or try deselecting the option to Edit Volume.
See if the volume in iMovie is set to its lowest setting. Directly under the Preview pane in iMovie is a volume slider. Set this slider to maximum volume.
Make sure the computer's audio is not muted.
Quit and reopen iMovie, then check the clip to see if it now plays with audio.
Check to see if any of the video clips you have imported are in the MPEG-1 format. MPEG-1 clips will lose audiowhen you export them as part of your iMovie project.
Quit and reopen iMovie, then reimport the footage from the camera. Play the newly imported footage and see if you now have audio.
If you are using an analog to DV converter instead of a camera, make sure the audio connections are good between your VCR or other analog device and the converter. Check the documentation that came with your converter for more information.
Check /Library/QuickTime/ and ~/Library/QuickTime/ for any third-party plugins. Remove them if present, log out, and log back in. Check to see if the issue persists. If not, check with the manufacturer of the disabled plugin to see if an update is available. Note: The tilde (~) represents your Home directory.
Note: "Apple Intermediate Codec" and "QuickTimeMPEG2" are Apple components. For more information about a particular plugin, select the item in the Finder and choose File > Get Info. Look at the version string of the Get Info window to see if the plugin developer name is listed.
iMovie is missing audio on import, export, or playback

I am using ALSA and Icecat. When I play any html5 audio/video it works, but the next time i click on another audio/video link I lose sound.

I am using Parabola (a fork of archlinux), Icecat 31.4 and ALSA
Icecat and firefox seem to hold onto the soundcard when I click on a new html5 audio/video link in the same tab. The next video/audio element loses sound. If I wait 10 seconds and click back to the start of the audio/video, the audio returns. I often get cpu spikes for icecat when it happens.
I have tried this with both motherboard and usb sound and I get the same problem. I have disabled extensions (addons) in Icecat, deleted profiles, reinstalled the browser and even installed firefox from the AUR and it still occurs.
I have disable gstreamer in about:config and restarted and it still occurs.
My .asoundrc is this:
pcm.!default {
type plug
slave.pcm "hw:0,0"
All my other audio applications work. I have noticed that if I use pulseaudio it fixes it, but it should work without anyway, like it used to. I think something happened after an update, but I'm not sure.
Any help would be appreciated. I know it's not a big problem, but it's really frustrating and I've had it for ages. I even switched browsers to get away from it.

*nerding out*
I am not an expert in this and if we get stuck I have found a mailing list for the alsa project that can be contacted: http://www.alsa-project.org/main/index.php/Mailing-lists
Gstreamer is disabled in Firefox as well as the os?
Since you are seeing issues with ogg files and moving video/audio combination I started to dig into file formats {sox http://sox.sourceforge.net/soxformat.html}
For ogg would the file format affect the "raw"?
defaults.pcm.file_format "raw"
Updated libraries
alsa-lib-1.0.6-8.FC3
alsa-utils-1.0.6-3
No no, here:

Is the OGG cpu intensive for your alsa architecture? [http://alsa.opensrc.org/Ogg]

Second user accont loses sound.

I set up a second account for my husband and it loses sound frequently. I login to my account-the sound works, then login to his account -it doesn't. Not the mute/volume. We restart, it's fixed, hour later- off again.
I haven't tested it to see if it works if I completely logout of my account, I just thought of this as I was typing it, but is there a common problem with this? I can't find any settings to adjust, etc.
I'm not technical, but I can follow software step instructions if pointed in the right direction.
Thanks.

There you go. Since I'm the only user, but have test accounts that I rarely log into, I've disabled FUS, finding it a resource hog.

Exporting with Adobe Media Encoder CC 2014 loses sound.

So... I've been having a hell of a time with the new Adobe creative cloud when it comes to video editing. The drop of .flv format, unable to straight export .H24 formats from after effects, it's a total nightmare. Here's the issue, to export as a .H24, you now have to use Adobe Media Encoder CC 2014. The biggest issue, however, is at the end of the export, when you open the video, half of the video's sound is mysteriously GONE. Just gone. If you go back to after effects, look at the file and the audio, the wave forms are there. There's nothing that would make it lose sound. Audio is selected on export... I have no idea what's up. Editing videos for youtube was a snap in previous versions of After Effects, now It's becoming almost impossible.

I think the same problem:
Part of audio missing in mp4 AAC rendered files from Watched Folders
Probably with cached files. Try this: Adobe Media Encoder 2014.2 Part of audio missing in mp4 AAC rendered files - cache problem? - Video Production Stack Exc…

No Sound in iMovie 10 imports

Hi everyone,
i've made several screen recordings and wanted to edit them with the newest version of iMovie. The video clips are all having sound while playing them with QuickTimePlayer and VLC Media Player, but as I imported them with iMovie, the sound in the video was lost. Can you help me?
I'm looking forward to your suggestions.
Greetings from Germany.

Hey there. You might have been bitten by the
installer permissions problem. Open Disk Utility and
repair your permissions. There is also a QuickTime
7.1.2 installer available.
Finally, try forcing prebinding to run. Open a
Terminal window, and type the following:
sudo update_prebinding -root / -force
This is useful for repairing system slow-downs, but I
have also found that this will fix situations in
which I have done updates, and the applications which
depend upon modules modified in the update don't "get
it" so far as the new updated modules.
Thanks for your reply.
I've tried repairing permissions, I've now downloaded and installed QuickTime 7.1.2 and have tried forcing prebinding all to no avail!
There is still no sound in iMovie but iTunes etc. work ok.
If there's no solution forthcoming I'll be forced to reinstall Tiger to enable me to go back to QuickTime 7.0.4

Can Reliably Lose Sound Effects On 10.4.5

I found a way to reliably lose sound effects on Mac OS X 10.4.5. I will report this to Apple using Mac OS X feedback.
1) Enable Fast User Switching.
2) Login as user1 and note that sound effects work.
3) Without logging out as user1, login as user2 and note that sound effects work.
4) Without logging out as user2, go back to user1 and note that sound effects still work. Then logout from user1.
5) Go back to user2 and note that sound effects no longer work.
6) Reboot system to restore sound effects.

Hi, Richard.
One question: are you using USB speakers? Have you tested this using only the internal speakers on your iMac?
Good luck!

MPEGs with sound in iMovie

Well I have a digital camera that records movies with sound, but when I try to import them into iMovie they end up with no sound. The help manual says that MPEGs wont work with sound in iMovie. So I was wondering, is there anyway to convert my MPEG movies into somthing iMovie compatible for sound like a .mov or DV. I've tried many products but they all seem to convert the video and leave the sound out just like iMovie does? Please help me.

No Sound in iMovie Import

Hello everyone:
I am trying to import a movie from my Sony DSC W100 camera.
The movie downloads to iMovie great, but I can't get any sound. I've checked the various volume controls on the camera, computer, and iMovie and everything seems to be where it should be. (And when I play the movie on my camera, there is sound.) But not so much as a peep of sound on iMovie.
I am using the USB connection - not a firewire connection (which I don't have for this camera).
My computer is an iMac with OS 10.4.9. I'm using iMovie 3.0.3.
Any guidance or suggestions would be much appreciated.
Thanks.

Welcome to the forums.
Looking quicking at some posted specs, your camera records in MPEG VX format (a form of mpeg1 or mpeg2?), which means that iMovie is converting that video format (MPEG) into a form it understands (DV Stream). If you open one of the iMovie clips using Quicktime, use the Movie Properties command to see if it has an audio track.
If there's no audio track, probably the video was muxed (audio and video mixed together). Typical recommendation is to use MPEG Streamclip to do the conversion from MPEG to DV Stream, but often you'll also need (to buy) Apple's MPEG plugin for Quicktime.

No sound in imovie using mpeg videos. HELP!

Hi, im a newbie, so I have lots of questions with sound in imovie.
I have a digital camrea which does the mpeg movie thing.
so when I import the movie into imovie I see the video but I hear no sound.
I know this was covered in some topics, but I being new to this I really didnt understand.
Im hoping that someone here and point me in the right direction.
Thank you.

Hi PK - welcome to the forum!
Increasingly, people with digital still cameras want to import their short movie clips created with that camera. BUT the catch is that these movies are NOT in .dv format. They are MPEGs, and if they are MPEG1 or MPEG2 then they must be converted to DV before they will import into iMovie with the audio able to play.
This conversion usually can be done with a free app. called MPEG StreamClip, but may also need another piece of software called the Apple MPEG2 Playback Component (which costs about $20)..
A search in this forum for those, will give you several threads on the issue!
Look here, for example, for more about the method required:

NOTE that iMovie was designed for DV use (a high-quality editing format), not the much lower quality MPEG footage.

No sound in iMovie 5

After upgrading to Quicktime 7.1.1 I've lost sound in iMovie 5.
Previously recorded movies have lost their sound together with any new recordings I make. Volume levels are still shown in the timeline but no sound is produced. All other applications appear to be working normally (iTunes, GarageBand, Audacity etc.).
To restore sound in iMovie I've had to reinstall Tiger together with updates to the current OS 10.4.7 and then install Quicktime 7.0.4.
Strangely this problem doesn't exist on my wifes eMac running OS 10.4.7 and the Quicktime 7.1.1 upgrade. Sound in iMovie 5 works perfectly.

IDVD burn has no sound in iMovie timeline video only

I used iMovie and iDVD to create a DVD. The DVD has an intro movie (that plays when the DVD is inserted), menus with motion and sound, a main feature with chapters, and a "bonus" short movie clip.
The intro movie, the bonus movie, and the menu movie all were dropped onto iDVD from individual .mov files. They all work fine in the disk image that I exported.
However, the main feature with chapters, which is an edited project that resides in iMovie's timeline, does not have any sound in the final exported disk image. Its sound in iMovie is contained in the 2nd audio-only track (the only one that is checked in iMovie) and it plays fine in the iDVD project.
Why is the sound missing in the exported DVD disk image, ONLY in the main feature when it works fine in the iDVD project?
It took 4+ hours to export the disk image... now it appears that time was wasted. I want to be sure that it exports correctly next time.
I have iDVD 6.0.1 and iMovie 6.0.1
Please help!

Welcome Ricky Brigante
Not exactly sure what the issue is here on why it failed to burn the audio as well but did you look thru the iDVD help menu first?
Here's the info I found and I hope it's helpful:
Preparing QuickTime movies to work with iDVD
If your video-editing application can export to QuickTime, you can create movies that you can add to your iDVD project. iDVD supports most video or image files supported by QuickTime.
QuickTime movies smaller than the standard DVD size of 720 x 480 (NTSC) or 720 x 576 (PAL) are scaled to fit the DVD window, which may decrease the image quality.
For best results, in the QuickTime export settings of your video-editing application, choose NTSC-DV with a frame rate of 29.97 or PAL-DV with a frame rate of 25. Choose No Compression for audio and set the sample rate to 48 kHz.
Not all QuickTime formats can be added to your iDVD project. For example, MPEG-1 or MPEG-2 files, QuickTime VR movies, and movies with sprite or Flash tracks cannot be added.
Note: If you drag a QuickTime movie file to an audio well in iDVD, iDVD uses the first audio track in the file and none of the video.
