Loss of audio when exporting

When exporting to quicktime I am losing all the audio attached to the movie , also the clips appear greyed out and only show the contents of the clip when I scroll over them, and I seem to be missing the clips in the events browser, am I missing something painfully obvious?

am I missing something painfully obvious?
Probably not. Have not experienced such problems myself, but it sounds as if the project file has somehow been corrupted and some pointers referencing source data have been lost/orphaned. Not really sure what you can do about it either at this point.

No audio when exporting from mpeg to flv

We have two PCs with Premiere Pro and AME installed, and just upgraded to CC. On one computer exporting works fine, on the other one, I'm losing the audio when exporting from mpeg to flv. I have used the same preset as on the other computer (that works) and also tried other presets that came with AME.
I can't figure out why this wouldn't work on one but works fine on the other? Anyone who knows?

How are you determining that the FLV has no audio? Are you playing it back in VLC Player or importing it into Flash?
Also, do you see a full range of formats on the system where you don't hear audio? If some formats are missing this might be a licensing issue. Also check if AME recognizes audio on the MPEG source (hover over it in the queue and look for audio info in the tool tip).

Corrupted audio when exporting in Soundtrack Pro 2.0.2

Hello, I am a sound designer and have been evaluating Soundtrack Pro 2.0.2 as an alternative to Pro Tools (I work with video editors who use FCP). The program has been working well until I have tried to export my work.
I have created a project containing audio of the same sample rate as both the project and the computer's hardware - 48kHz (eliminating a problem already highlighted by others) and using no DSP. Although realtime playback is fine, the exported audio contains blocks silence as well as wrongly mixed levels.
I have noticed firstly that the problem changes depending on where the loop markers are set. The problem is sometimes eliminated if there is a reasonable amount of silence at the beginning and end of the region being exported. Secondly, I notice that fades are not being exported correctly - either being exported as silence or as full level (as if there is no fade applied).
I have also tried using Soundtrack Pro version 1, and this exports fine. It's worth noting, however, that this version of the software does not allow the user to apply fades to the audio (without opening and editing the waveform itself).
Any help/suggestions would be greatly appreciated.

I know the problem you mean - the plugin settings are lost when exporting. I think this is a separate issue that has been fixed. An example of the problem would be when adding a fade to a sound, and then exporting. The fade portion of the sound would export as silence, but the rest of the sound would export fine. Very bizarre, and if no-one else is experiencing it, possibly it is to do with my machine. Unfortunately it makes the software unusable for me. My colleague, who is running the same setup as me, has exactly the same problem.
The main thing I like about Soundtrack is the ability to add effects non-destructively to each sound, and then go back and edit each effect later on. Also, the video display is good- showing you the video at the beginning and end of a sound when moving it, plus also where your mouse pointer is clicked. It has the potential to be a very good program.
Pro Tools HD is very good but very expensive. I know some people who don't like it, so I think its down to personal preference. It is used in every professional studio I have worked in, making it good for compatibility. You also won't find nasty bugs like the one i've described in Soundtrack - they've been developing the software for a long time. Personally, I find Pro Tools very quick to work with and very stable. Also, I would recommend Pro Tools LE if you're not going to be restricted by 48 tracks and lack of surround mixing.

Loss of audio in export.

I am experiencing a very frustrating sound issue. Any audio captured on my mini dv camera (sony HCR7 and sonyDCRtrv60e) via an external mic (RODE NTG2), while present on playback to the tape through the camera, and present on import to FCE, disappears when exported out of FCE. Audio captured to the camera's on board mic, however does not disappear.
One thing that Ive noticed - which may or may not help to isolate the problem - is that when viewing the footage through FCE, sound captured using the external mic is present if using apples external speakers, but if I unplug these and use to internal speaker, then this sound dissapears, while all other audio remains.
Whats going on??

What is your source, sequence settings and export setting. Which version of PP?
Prefebly a screendump of the export settings box.

Problems with audio when exporting to movies

Hi All,
I teach sequencing and one of the projects is to score a short piece of music to film. Logic Pro 9 is great for this (though beat mapping isn't the most friendly of functions) and my students (most only 16-18 years old) have made some great projects.
Right the question is what are the best settings to use when exporting the audio to movie? Some students don't get any sound when bounced or some are getting the oprginal with the new audio (doubled).
To assess and store student work we use vimeo for video projects and the wierdest thing is that when uploaded these bounces (the ones that worked) have no sound at all.
Never had these issues with Logic 8 and just wondering if anyone has any ideas on how I can resolve this?
Thanks and happy new year.

I've used flip4mac for about a year and have had no problems with it. I mostly use it to export preview versions for windoze people. The quality is very good, though it takes significantly longer to export than a similar-quality quicktime movie.

Garbled audio when exporting movies using iMove 09

Hello,
Whenever I try to export my Movie using iMovie 09, certain scenes have garbled audio.
The scene play properly within iMovie 09.
It also has the same garbled audio when I try to share it to iDVD.
Any suggestions?

There is a well known audio glitch in iMovie '09. If making speed changes to your project, such as slow or fast motion, you must use only the presets shown on the speed slider. These are: 12.5%, 25%, 50%, 100%, 200%, 400% and 800%. Do not use custom speeds, by manually entering your own percentages.
If you don't use the presets, you are highly likely to see audio problems in the exported project. As you have noted, the glitch appears only in the export but is not evident in preview (within iMovie).
The only fix (other than going through a convoluted process) is to adjust all custom speed changes to the presets. This is a nuisance, of course, as you may have to resync the video and audio where you have added voiceovers or music tracks.

No audio when export to flash

When I export my presentation to Flash, the audio is gone. Any ideas? No such problem when exporting to QuickTime Movie...

No audio when exporting to h.264 (mp3 - aac conversion fails)

Using QuickTime Player Pro 7.5.5 on OS X 10.5.6:
I have a video file (video format: On2 VP6, audio format: MPEG Layer 3 mono) that I am attempting to export for high-quality YouTube.
When I export to H.264 my only audio export option is AAC-LC. But the resulting mp4 file has a silent audio track. I've tried different settings on the audio (mono/stereo, different data rates) but that makes no difference.
Is there a way to successfully export the audio when using the H.264 format?

Thanks -- it's too bad QuickTime Pro doesn't properly handle this. I successfully used iTunes as a workaround as well (I exported the audio track to a standalone mov, opened in iTunes, exported as an MP3, then added back to the video in QuickTime Pro).

Distortion in audio when exporting HDV to tape

I'm having trouble sending a native HDV project back to tape. The picture looks fine on the export, but the audio is severely distorted. It's not overmodulation. I have a -10 limiter on the audio master track, and the VUs on my deck don't show anything like any clipping. But the sound it's making is similar to clipping. Any ideas? Thanks,
Stu
system specs:
Dell Precision PWS390
Intel Core2 6400

Howard,
Thanks for the reply. It's hard to describe the sound...it actually reminds me of the sound a 16mm projector makes when it loses its loop, sort of a strobing distortion. As for constancy, no it's definitely not constant in the sense that, say, ground loop hum is constant. It's "attached" to the sounds as the play back, so that when the timeline is very quiet it's hardly audible, but when you get any sound at all, it comes up. I know that might sound like clipping, but I don't see how it could possibly be for a few reasons:
1. There's a -9 limiter on the audio master track.
2. It sounds perfectly fine both in timeline playback and when exported to Encore.
3. The VUs in the original source clips, the timeline, and the deck on output all show clean levels with no clipping.
I'm wondering if it's related to my deck, but I haven't had a chance to check that yet. I'll try outputting to the camera when I get back in to work on Monday, but if you have any other ideas as to what the cause might be, I'd be happy to hear them. Thanks.

Compressor 3 no audio when export mpeg 2 ts

I imported a .mov files to compressor 3, but there are no audio when I export Mpeg 2 TS(by default setting)...
(1) I can hear audio on preview
(2) export no matter extentions m2t or mpg , no audio.....

the mpeg2 files mux (mix) the audio & video together in one stream.
To work with the files in FCP, you must demux them. The application MPEG Streamclip can do this for you. Google it, it's free.

IMovie9 places random audio when exporting!

I have a problem that seems absurd. Forgive me for not being too technically inclined.
I have spent countless hours editing a movie with music overlaid as well as audio grabs moved etc. It looks great on screen - usually.
Sometimes when played back it loses some of the original sound. If I go to the audio of that clip and basically do nothing but check it and hit 'done', it returns.
More confusing is when I export. I have tried exporting to iDVD and Toast to put it on DVD and for some reason it places random audio. There will be a car scene with music that I placed and suddenly there will be voices or waves crashing from a totally different source. There is no evidence of this audio when I check the project.
Another problem is that it refuses to remove audio when I have reduced the volume to zero, for example when I have fast motion and don't wish to hear the squealing sound. My only solution is to detach the audio and delete it. This is a problem that is frustrating but can work around. The first issue is my main issue as it makes all my efforts worthless.
The management of the audio seems quite random and uncontrollable during export.
Does anyone have any ideas or experiences
Thankyou

Of course that's always the way
As soon as I posted the question I found the possible answer.
Speed changes not on the marks like 200% or 400% cause the problem. I have many at 80%. Exactly where I want it and if I change to 50% (looks crap) or 100% (kinda pointless) it will stuff up my timing completely.
Wonderful. Starting to dislike iMovie. hmm

No Audio When Export

I'm using Final Cut Express 2.0.2 on an iMac G4 with OS X 10.4.8. I have a two minute film I'm trying to export into an .wmv format to put on the web, and each time the finished project has video but no audio. I've mixdown rendered the audio, I do hear the audio when I watch the clip on FCE (and I get audio levels), I've tried restarting the computer -- I'm not sure what else to do. I've done this a million times before and never had any problem like this. I've looked on help pages, too, but have yet to find anything else I might try.
Help!
i GHz PowerPC G4 Mac OS X (10.4.8)

FCE is using Quicktime Pro to export to WMV. And how am I listening to the files -- after I finish the export, I've tried playing the files in both Quicktime and Windows Media player, but I get no sound from the speakers. I've tried plugging in my headphones to see if I could hear the file that way, but no luck.
Thanks very much.

Has anyone experienced the loss of audio when using Apple TV when it has been working fine?

I can't get any audio through my reciever when using Apple TV. It's been working fine until a week ago. I've check my reciever, unplug the TV, and Apple TV as described but nothing. I switch to my Direct TV input and I can get audio when not using ATV. I've tried most everything I've read on blogs but nothing. One of those "pull your hair out" issues. Any direction would be appreciated. Thanks, Vince

Hi there Vfall!
I have some information for you that can help you troubleshoot this issue:
If you can see video but can't hear sound
If Apple TV is connected to a receiver, make sure the receiver is turned on.
Make sure the input setting you've selected on your receiver matches the input you have your audio cables connected to. See the documentation that came with your receiver for more information.
Make sure the volume on your TV or receiver is turned up and isn't muted.
Check whether you can hear sound while playing video only. Also, check whether you can hear audio feedback while clicking through menu options.
If you're connected to the HDMI port on your TV and Apple TV, make sure your TV supports audio through its HDMI port. The HDMI ports on some older TVs support only video.
If you are using HDMI audio, try disconnecting and reconnecting the HDMI cable.
If you're connected to the HDMI port on your TV and Apple TV, make sure your TV is setup to receive audio from HDMI. For some TV's this is automatic, but for others there is a choice between digital and analog (for HDMI audio, choose digital). Read more about HDMI audio.
Try the other audio outputs on Apple TV to see if they work.
If possible, try using different audio cables.

**Missing Audio when Exporting to HD**

Hi,
I have been trying to find a solution to missing audio for sometime and there are many discussions on this forum regarding this topic. I have an external drive and in the past I have lost audio, I guess because the event and the project were on different drives, I have resolved that. Also, the problem that I have is not related to the speed of a clip or that I have more than 10GB in my events (I don't). There have been other audio issues and I have always been able to resolve them but this one has me stumped! I thought that perhaps the graphics card was not up to the task but this has just happened and now I am confused.
I have just completed a project that was only 3 minutes long 403.5 MB. The movie was imported to iMovie from my video camera and listed as an Event, I also used movie clips and stills from iPhoto, I added titles and transitions. I then exported the movie to Media Browser (mobile size) so that I could import it into Garage Band to make an soundtrack. I then exported the soundtrack as an AAC to iTunes (as I have read that there are issues with MP3 and audio missing). I then opened iMovie and dragged the soundtrack into my project and republished the completed project to Media Browser in the HD size. No problem all works well, I was really happy! Onwards I thought and get another 2010 video finished, wrong!
On my next project I have done everything that I have described above, this time the project is only 349.8 MB (smaller). The audio on the HD size has failed. I have copied all the files onto my desktop and reimported everything. I have tried exporting using Quicktime or as a Movie but still no audio. I have found that the 'consolidate media' is grayed out when I have all my clips in the project editor, because they are all on my hard drive. As soon as I add the iTunes track that I have exported from Garageband the consolidate media option becomes available. If I select this I then get the message that the iTunes track cannot be copied as it is not on my hard drive! It is on my hard drive (I disconnected all external drives so that there would be no confusion!).
I cannot understand how the first project worked and the second smaller project failed using the same process! I thought that I would share this information with the forum in the hope that perhaps a solution can be found. I am able to publish the second project to my mobile me in the large and mobile sizes, it would be good to have the HD size for a DVD. There seems to be no logical pattern to the audio disappearing on export. Your thoughts or help would be very welcome.
Kind regards,
Watchthebat.

In Soundtrack if you have selected to use only channel 2 of a stereo file (right click on stereo file and select mono->channel2) you will hear channel 1 when you export. Its a massive bug.
Could that be the source of your problems? The bug can certainly create exported mixes that sound like stuff is missing.
There's a recent thread around here about this.

Loss of Audio when opening Motion project in FCP

I have a 2 minute video I put together in Motion. When I then open the file with FCP the video looks great but the audio is not exported. When I save the file I state to save both audio and video. Any suggestions?
Thanks

Oh dear, I feel like such a noob now
EDIT Figured out what CTI and Match Frame is
and how do I check for .pek files?
Thank you for your time
