Exported movie has choppy audio

the whole animation plays smoothly when previewed on FCP X. But when I export it, the sound becomes choppy. I got the sound effects from FCP X sound effects.https://www.facebook.com/photo.php?v=10150667439902717&set=vb.50603525802&type=2 &theater

Apple did not want to become the next Napster to go down "lawsuit lane"....... then Apple came out with the AAC, telling us it was for better quality than of mp3, but also behind the scene, they were also imbedding songs on their site, with "copyright" features that prevented user from other computers to share and or play songs not purchased ligit.
Apple did not develop the AAC format. From http://en.wikipedia.org/wiki/AdvancedAudioCoding
AAC was developed with the cooperation and contributions of companies including Dolby, Fraunhofer IIS, AT&T, Sony and Nokia, and was officially declared an international standard by the Moving Pictures Experts Group in April 1997
For details of the improvements over mp3, have a read of the above link. I suspect the reason Apple chose the AAC format is the lower licence fees and the better quality and lower bitrates.
AAC's (like mp3 and wmv) can be DRM protected, and this is the format that most of the tracks sold in the iTune store use.
So mp3 are safe with iP4. But as you upgrade to iP5 or 6, and iTunes 6 or 7..... I beleive iTunes becomes smart and prevents you to even play mp3 or use them with Quick time if they have the DRM (copyright feature) I have encountered this problem before when I attempted to upgrade my iTunes.....and immediately, I reverted to iTunes 4.2... and it allows me to put songs on my QT files.
This is untrue. You can use DRM protected material with later versions of iPhoto and iTunes, within the limit of the DRM, of course. And you can use any unprotected material.
There might be other reasons (beyond my knowledge) why mp3 and or mp4 (AAC) do not play in QT in higher iTunes version.....
They do play, perfectly well. It sounds like you have a problem, but it's usually sorted out by having the latest version of iTunes and Quicktime

Imovie exported to mp4 choppy audio on PC QuickTime player

When I created a mp4 file from imovie, my client with a PC who has a QuickTime player hears choppy audio. It won't even open in his Windows Media Player bc of Codec issues. Then QuickTime plays it but audio is all choppy. It plays fine on my Apple. What am I doing wrong? If I create a QuickTime file, which I'm doing now, is there a special audio setting I should change so this will work on a PC?
Thanks!

When you export out of iMovie are you doing it using Share> Export QuickTime file or Export Movie? Believe it or not, you can export to Movie and rename the file extension from .m4v to .mp4 and get that to play on any Windows machine with Windows Media Player installed. It maybe a simple matter of saving it out to Movie, renaming it and sending that one along to the client, see if that one works better.

Movie Has No Audio

I'm new to the iPod scene, and am ripping a few movies from my DVDs to stick on my iPod. I've done 4 movies so far. 3 worked great, but 1 has no audio. It's the problem described here:
http://docs.info.apple.com/article.html?artnum=302588
Except that the file in question isn't muxed, from what I can tell. I opened it in QuickTime and clicked "Show Movie Info" like the article says, and QT says the movie is MPEG4. It doesn't say "MPEG1 Muxed" or "MPEG2 Muxed."
I used DVD Decryptor to rip the DVD. After ripping, I can play the VOB file in Windows Media Player with no problems (after renaming it to .MPG). But after converting it with Videora, the audio is gone. I've tried both MP4 and H264. Same results.
What the heck?

Am I better off just springing for QuickTime Pro? Can Pro convert the VOB files to an iPod-readable format?

When I export my project, the exported .mov has green and grey bits in it?, When I export my project, the exported mov has green and grey bits in it?

I am using Final Cut Pro Version 6.05.
What I mean by green and grey bits is that in the exported footage randomly some scenes will be replaced with a green or grey screen instead the footage. The audio remains the same.

Hello Russ,
I have FPC X 10.1.3 and Yosemite. Thanks for your concern but i solved my problem. I created new library and copied event in new library.
Everything is back to normal now. The share button lives again.
kindest regards

MPEG-2 movie has no audio.

Isn't it possible to create a self-contained MPEG-2 movie with audio and video? Each time I import a self-contained Quicktime movie created in FCP into Compressor and encode a MPEG-2 movie using the MPEG 6.2Mbps 2-pass setting, I never get any audio.
The long version of this story is I have to get a 4.5G Quicktime movie file onto a DVD and it won't fit. It's in 960x720 HD. If I could just do a little compression to trim off a G or so all would be fine. Each time I try a "Quicktime conversion" compression option it makes the movie 4:3.
Thanks!

Isn't it possible to create a self-contained MPEG-2 movie with audio and video?
Yes,
Compressor presets>Formats>Mpeg2>Programme or Transport Stream.
(Ignore Elementary stream)
Hit page 183 of Compressor's manual for more info.

Quicktime export = choppy audio first 5 to 10 seconds

When I export a composition to a Quicktime movie file using the default settings, I get a file that has choppy audio for the first 5 to 10 seconds and then it smooths out and plays just fine.
However, when I shift everything forward on the timeline by 10 seconds and then export the composition, the audio plays just fine once the movie starts playing.
It seems like up to the first 10 seconds of the audio get corrupted on an export. I've tried all different combinations of Quicktime export settings and get the same results. I'm pretty sure it doesn't have anything to do with the audio file itself; I'm only using high-quality .wav files.
Details:
After Effects v8.0.2.27
QuickTime Pro 7.4.1
Windows XP SP2
Core 2 Duo, 2GB RAM
Any ideas?
Thanks,

OK, tried the suggestion from Jonas on avoiding 'Export' and used the render queue instead and... Viola! Worked like a charm.
I went back and scrutinized the differences between the two and found the problem; the export settings were set to 44.1khz for the audio vs. the 48k for my render queue setting. I changed the audio to 48khz for the export settings, tried it again, and this time the problem was gone.
Thanks again for the tips and ultimate solution.

Exported movie is not the movie I see in FCP

Hi there,
In a Project which was created by another cutter, I export a .Mov from FCP.
The exported movie has the same edits but some of the content is displaced/shifted.
I tried a lot of things to solve the problem.
I checked if the imported footage was some kind of strange
I threw away all the render files of the Project
I opened the original captured footage and saved another .Mov
and (re)connected it
I used FCP-Rescue
none of that worked out for me.
In this Project, the cutter made a lot of speed changes to the clips.
Could this be any hint?
Or could it be anything with the tape?
And:
When I opened the project first I had to Lip sync some parts of the edit.
But as I said everything looks fine, when I watch it in FCP.
Any Ideas?
Cheers,
Shahin

In my experience, this has only happened when media has been moved from its original location.
Provided you're not working with a long sequence, my advice is to match back your edits and splice the in again. This will assure a mirror export of your sequence.
Good luck,
Mario

Quicktime Export Fails to Recognize Audio in MPG1 files

When exporting MPEG1 to any other format with QT Pro, audio options are greyed out ('No Audio in Original'), and, predictably, the export file has no audio.
VisualHub exports MPEG1 with audio just fine. But I've paid for QT Pro, and not VisualHub.
This has to be a bug in QT, right? MPEG1 is, unfortunately, still pretty common, and I would think Apple wants users to be able to put whatever video they have on their iPods.
Thanks in advance.
QT 7.1.3
OS 10.4.7
NB: Is it possible for moderators to retroactively edit topic subjects to be much more specific? The more likely a visitor is to find her topic answered, the fewer new topics there are, less repetition, etc.
Even better, consolidating the most common questions into 5 or 10 stickies would save visitors much time, and the people who answer these questions, exponentially more time.

Thank you for the answer. The information was useful, the tone was not what I expected. When I asked whether more specific headings could be encouraged, I meant it out of sympathy for the moderators/answerers, not to incur their ire. Perhaps it would have been better if I'd left out the editorial comment.
I searched for 'audio', which I thought was a more technical term than 'sound'.
I read the indicated specs for QT above. The MPEG shortcoming is not laid out there clearly in any sense. MPG is not listed as an export format, so from that I would conclude QT can't export to MPEG1.
It is clear in the Apple article. For it to be 'clear' to anyone right away, it should be added in one sentence to the relevant help section of QT: 'QT will not export files with some codecs because of their proprietary neature.'
Or it should be in a pop-up message as soon as you try to export an mpg: 'Because mpeg is ownded by someone else, export will only render video'.
I believe I asked a valid question, and provided a specific account of my problem, so this post will be useful for future browsers.
Because VisualHub dealt easily with mpg, I thought QT must too. I was wrong.

.Mov files in CC : The File Has no Audio or Video Streams

I recently updated premier to CC , since i have issues iimporting any .mov files at all.
The specific ones Im trying for my current project are exports from AE , rendered lossless animation .mov , worked fine in CS6 , will play in quicktime and other generic's but always getting the The FIle Has no Audio or Video Streams message when trying to import into a project.
Quicktime is updated so I can't understand why the won't play, is this a CC bug ?
i go back to cs6 on my other comp they open fine...
Ive seen a few topics on this none with a resolution and most of those where from cam's, this is an export from AE, anyone able to help this is stopping me from working atm ......

I can verify that Apple screen recordings without audio do not import into any Adobe premeier.
Details on screen recording from Gspot v2.70a:
H.264
qt : Apple QuickTime (.MOV/QT)
File Type: QuickTime (.MOV)
Mime Type: video/quicktime
Len: 1:03.083
Frms: 1,521
Qf: 0.153
Frames/s: 20.000
wx: 1280 x 800
sar: 1.600 (8:5)
However Apple (MAC OSX) screen recordings WITH audio will import.
I would think this should be fixable with hotfixes...
If you (adobe staff) have access to macbook pros 2012 or 2013 models, open quick time pro, do a screen recording, make sure no audio is recording, just your screen movements.. then export to 1080p video (mov is only option).. then on a windows PC try to import that file into adobe premiere. The file will play perfectly fine natively in windows with any player so long as a H264 decoder is available on that system... the problem here is Adobe Premiere. Not the users system.
Edit:
To help those with this issue.. just make sure when you render your mov that you have ANY kind of audio in it.. and just remove the audio track once imported into premiere. I know it's frustrating and you would think something as simple as not having an audio track wouldn't break premiere but alas... we have to work around the shortcomings until they decide to fix it.. just like the VFR issue in premiere.

Video on Exported Movie Freezes During Playback, Audio Continues

This is a reoccurring problem I've found in some of my exported movies. After successfully exporting a project (in full quality), I view the movie in QuickTime player, where, somewhere in the middle of the movie the visual freezes and stays frozen on the same frame for the remainder of the movie. The audio however doesn't skip a beat and continues normally. The playhead in the QuickTime player continues without interruption as well. The location (or frame) where the movie freezes is always the same every time the movie is played. If you attempt to skip over the freeze spot by clicking later in the timeline, you'll successfully move the playhead forward to where you want but the visual is still frozen on that frame and the audio is fine as well. This suggests to me iMovie rendered the movie to a certain point and then, for some reason, rendered a still frame for the remaining duration.
The movie plays normally in the playback/preview within the iMovie app. itself.
The only clue I have is it seems to have this problem after a slow or fast motion effect is used. The frozen frame is generally the last frame in the clip that has a slow motion effect. If I go into the project and move the end of the clip forward to erase the troublesome frame, export, and view, the movie is completely normal until it hits another special effected clip.
This is truly a hassle and the poor solution I've found to fixing it ruins the synching I've put a lot of work into.
Help would be greatly appreciated. Thank you so much.

I have had the same problem on multiple movies. I'm going to submit your post to apple feedback & I suggest you do the same. Have you found any solution? http://www.apple.com/feedback/imovie.html
I think the problem is related to running out of memory/virtual memory, so on another post I saw rebooting & shutting down other programs before rendering suggested.
Exporting in a smaller size worked for me, but I didn't create this movie to watch in postage stamp size. I'm a new mac user - what happened to apple's promise of things "just working"?

H264 AUDIO movie has no sound in Quicktime.

Hi.
I have a movie file which was playing the video, but no audio in Quicktime 7.6.2. I opened up the movie properties and saw under the name column a heading "English 5.1" Under the format it is listed simply as "sound". In the movie inspector it only lists the video format (h.264 704x480 millions) and no audio format... which is obviously why Quicktime is not playing the sound. However I opend the movie with VLC and Divx players and they played the movie with the audio with no problems. Mplayer also played it with the sound. I have ffmpgx so I used it to check the source format for it and it listed it is as a matroska (.mkv) container (which I knew), the video as h264 yuv420p 704x 480, but the audio was isted as "h264, 24000 Hz,5:1" I've never seen a h264 audio format before! Is there a codec I am missing to play it? I already have the most recent version of Perian (1.1.3) installed. Am I missing a codec? Can quicktime not play this format? Any input or ideas in general? I could use ffmpegx to export it to another audio format, but I'm just wondering why the original audio format does not play in Quicktime.
Thanks in advance!

AAC-SBR is also known as HE-AAC:
http://en.wikipedia.org/wiki/High-EfficiencyAdvanced_AudioCoding
QuickTime does not, to the best of my knowledge, natively support HE-AAC, or a least only supports it in a MOV or MP4 container (I've read contradictory information on HE-AAC support). I haven't found a QuickTime codec plugin that would allow QuickTime to play an mkv file with HE-AAC audio, so unless someone else here has further information, you'll probably have to convert that file to a different format to get it playing in QuickTime.
Regards.

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.

Export all tracks as audio files in LPX has suddenly ceased to function correctly

I have been working on a project for the past three months, which requires me to work from home ,then export all my tracks as audio files and take them into another studio. This is because my collaborator's DAW of choice is now Nuendo. So far, this has proved to be a very successful approach to our workflow, until today. As an example , I have a cue with 96 tracks. When I came to use export all tracks as audio files, the usual window came up, defaulting the destination to the bounces folder in the Logic song. However, this time, instead of the expected and correct number of tracks to be saved ( 96 ) , the total was 25 !
I tried this with a few other recent Logic songs and the same thing happened. None of us can figure it out. I had to manually, and individually, bounce each track separately, which was very time-consuming. A clue, though….. I tried exporting the tracks one at a time. So, the first one was, say, piccolo rips. It did that fine . The second track was Alto flute runs, but when I came to export, Logic seemed to think it was still the piccolo rips! This implies that the reason why I'm experiencing reduced export files is because Logic is thinking that many of the tracks are actually duplicates, so it's stopping them from being exported. That's the only explanation I have. However, I don't have the answer to the reason for this. I'm running the latest version of Logic.
Has anyone clue as to why this has suddenly started to happen and how it can be fixed please? I'm thinking I might just trash the Logic app and reinstall.
Many thanks for any help.

First of all you are welcome...
I have to say... I suspect something has changed even if you are not directly aware of it.... between the time it did work and now that it doesn't for you... Be it for example... an update to a plugin you are using.. or even a new/different plugin you are using now that you didn't use before...
I checked with one of my clients a few minutes ago, who does regular, several times a week, large project stem exports to see if he has ever had or heard of such an issue ( in case it one of those odd bugs that only rears its head every now and again..) and the answer was no, not at all...
So all I can recommend is to create some testbed projects.. using different combinations of Plugins, creation of tracks methods.. templates etc.. until you uncover the root cause of the issue... because i suspect it may well be something unique to your system, config or work method that is causing this problem..
You might also want to check with the guys at
http://www.logicprohelp.com/forum/index.php
..and see if David, Jordi, Eric or one of the other regulars there, have ever come across such a problem.. I did a quick cursory search there and found nothing at all but it was a very quick look/see type of search...
Maybe CCT, Pancenter... or Edgar here.. might have an idea or two, too...
Finally, Can you also state your current OS X / Logic version please...
Cheers..
Nigel

My movie has clips that have some extracted audio that I would like to use for the menu music in iDVD 11. Does anyone know how to do this? Copy and paste does not seem to work.
