Choppy movie, corrupted audio

My computer does not support a Quartz Extreme Compatible Graphic Card. I have an iMovie that became choppy and now has corrupted audio. Could this have happened when I upgraded from standard iMovie to iMovieHD? The iMovie may have been originally created in standard iMovie and upgraded when I opened the file after installing the upgrade. I have some iMovies created using VHS clips which are also corrupted. I have tried deleting the iMovies preferences, which did not help. The iMovie will run fine with the audio deleted. The entire movie, audio and video runs fine on my iBook G4 with the same version of iMovie.

Choppy playback, sometimes called stutter, can occur when a project contains many audio clips. iMovie 6 is a bit more sensitive to the number of clips than earlier versions, which may explain why the problem began after converting.
Here's a (long) description of the problem, offering several workarounds:

Solve my corrupted audio problem for $$ and eternal gratitude

My video project has corrupted audio suddenly. I've read about other audio problems when exporting, but all I did was save the project while editing, no export. I have the prefs set to extract audio at pasteover, which I've done a lot of for this 2-camera wedding shoot. I also have the second audio track occasionally used for background music. All three tracks (video, audio 1, audio 2) on the timeline have corrupted audio for the entire length of the project. It sounds like a helicopter whirr was added, it's very choppy. Also, both cpus are maxxed out and the process monitor shows iMovie utilizing 180%+ consistently. When iMovie isn't running, it's in the single digits. As soon as I load iMovie the cpus max out. This hasn't happened the whole project, just recently. So what changed? I don't know. I've been doing the same thing the whole time, the pasteovers, the add titles, the add background track, saving the project every couple of minutes. Each time I've saved, it looks like it's listing off different files or clips, not just the changed clips. I've tried deleting the QT movie it created in the cache and let it recreate to see if that would help, but it didn't. Would deleting the files in the waveform cache help? I've got about 30 hours into this project already and would love to resurrect this audio if possible. Either that or it's Jim Beam and call it a day. I thought this was non-destructive editing, but apparently that's just the originals? That doesn't help much when the whole project audio goes in the toilet and I'm looking at redoing this whole project. Anyone who can fix this is getting a big ol' sloppy kiss on the mouth and an iTunes gift certificate.

I've never personally seen the audio problems you describe, but there's some things I'd try before giving up. As you've probably read, it's not unusual to have playback problems in projects containing complex audio. The odds for it seem to increased in QuickTime 7.
1. Try opening the "TimeLine Movie.mov" that's inside the Cache folder of the project in QuickTime Player. If the audio plays okay there, the audio data is intact and you're seeing a playback anomaly in iMovie. (QuickTime Player may choke too, but don't conclude anything from that.)
To access the movie, Control-click on the project icon and choose "Show Package Contents".
2. Try exporting ONLY the project audio to an AIFF file, then import THAT back into the project and replace the audio you have. That will "flatten" the audio and make it much easier to play. (To be safe, on a copy of the project.)
Or if you have QuickTime Pro, you might try extracting all the audio from the Timeline movie.
To export to an AIFF file, choose File > Export, click on QuickTime, set the popUp menu to "Expert Settings", press Share, then from the top popUp menu, choose "Sound to AIFF". Choose the level of quality you want from the bottom popUp menu, then Save.
What may be going on here is that extracting audio has created MANY audio files in the project, some possibly very large. (Each time we extract audio from a clip that is part of a Media file shared with other clips, iMovie extracts ALL the audio from that Media file, not just the audio of the selected clip.) To see what audio files the project contains, look in the Media folder of the project.
If you get this solved, please say how.
Oh, and if you haven't updated to iMovie 7.1, you might try that. There were improvements in handling multiple audio tracks, I read somewhere.
BTW, it's usually not a good idea to change things inside the project package. iMovie can get pretty confused. The Timeline movie is replaced each time we save, so that's not a big deal.

Major bug-NEED HELP. Move any audio then no sound.

Hey..I came across what has to be a bug and it's stopped me in my tracks. I have the latest version Of Logic Pro 8. I laid some guitar tracks but everytime i try to move them to get them in synch with the grid after I move the track, there is silence. No meters visible in the MIXER..NO SOUND will play..I Undo the move and everything plays again. These are continuous audio files. Also, in this particular session now if I move any track at all same thing..All audio stops and it's as if you are looking at a blank session even though you can see all your waveforms in front of you...Now, I have out of time guitar tracks and I'm stopped dead....I tried bounding the tracks to audio and reimporting them but same thing happens...ANY TIME I move any audio, ALL SOUND STOPS.....Anyone have any ideas? Thanks.

I just purchased extra storage for my iCloud. How and where do I access it? I purchased movies and audio books to find out that I didn't have enough storage (the reason for the extra storage purchase). I have no idea where to find them now. Help?!

How do I use my iCloud???
I purchased 4 movies and 2 audio books from iTunes only to find out my iPad2 didn't have enough storage, so I purchased more storage from iCloud.
My iTunes account only shows the 4 movies that need to still be downloaded (not the two books) After purchasing 20GB from iCloud I am still receiving the "There is not enough available storage. You can manage your storage in Settings" message. I have gone to my Settings, where it shows I have the new, extra storage. I have set all the iCloud settings as shown on the Apple website. In my iCloud settings, it shows I have 17GB available out of 25GB. In my General settings, it shows that I have a capacity of 28.6 GB, while my Available is 2.9GB. (????)
I don't know why I still can't download the movies. I wouldn't know where to go (how to get to) the iCloud if I could...
Also, iTunes has sent me receipts for the movies and audio books I purchased as well. Where are they???
Thank you SO very much for any assistance you can offer me!

Cancel your storage upgrade
If you upgrade or renew your storage but no longer need it, you can cancel. If you cancel your storage plan within 15 days of an upgrade or within 45 days after a yearly payment, you can contact Apple for a full refund. After this period, you can downgrade your storage for the following year.
Note: Partial refunds are available where required by law.

The latest .key I created is huge, .... Finder shows it as 5GB. Other .key of similar slide total are about 300-500MB. There is nothing different about this one. It is just .jpg files (photos) and text. No movies, no audio. Why so big??

iMac. 2.4GHz. Core 2 Duo. 2GB SDRAM. OS - 10.9.5.   Keynote - 6.2.2 v.1878.
I just completed a keynote slide show. The Finder indicates it is 5.25GB. It is 200 slides, no movies, no audio of any kind, no special transitions. It is just photos and some added text explanations. The individual photos are each 5-6MB, with about 190 photos total. I have other previous .key's about the size in terms of the number of photos and they are showing in the Finder as taking up 300-500MB. There is nothing different with this one particular presentation. I usually organize and store my photos using .key after a trip. Photos are downloaded into iPhoto (7.1.5) and then I build a keynote presentation by copying the photos as .jpg's out of iPhoto and into Keynote, with text as notes on or under each photo. Something changed with the latest keynote in terms of file size. But I can't determined why it required 5.25GB of disc space while other .key's of the approximate same size and content are only taking 10% of that amount. Anyone have an idea what is going on with keynote is this particular instance??? I know I could compress it, but I want to understand why the last time I used keynote the file size was so huge.    Thanks for the help.

Some additional information. In looking at the package contents info, under the DATA Folder there are several entries for each slide/photo in the .key presentation. There is a long list of contents that shows each image as:
    pasted-image-1234.png
and a second list right below that identifies each image again in the .key as:
    pasted-image-small-1234.png
Both of these lists show image files of 15-25MB for each photo, even though the original .jpg photo was 4-6MB. They list/show all of the images in the .key, but DO NOT show the added text. So it appears the package contents indicates two separate .png files for each photo in the .key, but the file size for each is 3-5 times greater than the original .jpg that was copy/pasted from iPhoto. And for some reason there are two copies of each.
There is also a list for the two following image/data files:
    pasted-image-small-small-1234.png
    st12-1234.png
Both of these lists show a file size of 100-200KB for each image, and again show all of the images in the.key.
Only the st-xx-xxxx.png list of images also show the added text.
Again it appears when I created the Keynote presentation by copy/paste images from iPhoto, Keynote stored multiple copies of each image as .png file several times larger than the original .jpg.   The completed Keynote slide show is so large is almost impossible to work with. The system is so slow that routine commands are not completed, e.g., trying to "save as" into a .pdf never finishes and I have to "force quit".
Still trying to determine why this occurred with the 6.2.2 version. Any chance I can delete all but the st-xx-xxxx image list and get back to a normal file size??

From my PC how can I see what is stored in my cloud? Reason is I want to move an audio books from my Ipad to Iphone. I am new to the Apple products.

I am new to apple products. Have a Window 7 PC, I phone 4s and Ipad . I want to move an audio book purcahsed on the Ipad to my I phone so I signed up for the cloud because it said what I described above would be possible. How do I do it? Also, how can I see exactly what is in "my Cloud" and selectively downloard the bits and pieces of what is in m cloud to a particular device. Thanks in advance to anyone and everyone.

Thanks pvonk, I will try downloanding the book from the Iphone right now.......
Just tried to download and it wants me to buy it again? Is there some way around this? I guess I thought that was the whole point of the cloud, buy it once and access from any of your devices right?
Also, I have logged into the icloud.com as suggested and will plink around there for a bit and try to understand. It is just all so dang different that what I am used to; Apple's way, that is.
Thanks again for the Icloud tip and if you know of a way to download without making a 2nd purchase I would sure love to hear it!
Geez. one other thing (I guess I am complaining) but I bought more space in the cloud, they took my cash fast enough but have not yet increase the size of my storage space yet? Is Apple sometimes slow to get internal stuff done?

I have FCE 4.0.1 and running OS x 10.7.5 when i burn my movie the audio from my movie clips don't come through . My Sound effects and music can be heard. I export to Quicktime movie, make it self contained then open IDVD for an intro and burn it.

First I export to Quicktime movie, make it self contained then open IDVD for an intro and burn it. everything sounds great in preview but then ( once again)I lose my audio from my movie clips.

Try Mixing Down the audio before export.

I cannot find the eMac install disk, and I haven't been able to get it to start up from my 10.3 CDRm (holding down option or c), though I read something somewhere about these not being able to start up from system folders earlier than those they shipped with. I've dealt with this sort of thing several times before, and it always seemed to work to simply use target disk mode.
It definitely won't start up fromt the 10.5 DVD-R, and I'm pretty sure I tried putting the MBP into TM to use its optical drive as well, but it didn't work. But it's worth trying again, and I appreciate your input greatly.

Video choppy after adding audio

This is my fourth year creating a basketball highlight video for the local high school and I have a new problem I haven't been able to solve. I've imported clips from the past 5 games using iMovie HD and everything worked great. I recently added a song for background music (same thing I've done previous years) and now when I play the video it is real choppy. The audio plays fine.
I've seen previous posts regarding this topic suggesting exporting the video with sound track and re-importing. I can't do this because I'll have to go back later to shorten or lengthen clips depending on how the rest of the season goes. I also read you can solve it going back a version in QuickTime, but I can't do that with 10.4. I have playback set to Standard under preferences. I'm using an external firewire drive with 30gb available. iMovie is stored on my internal drive. I've ran all the recommended maintenance on my mac. Does anyone have other suggestions?

Same problem here. Do you have a lot of audio clips? I'm working on a project with around 40 audio clips, and I find that if I delete half of them (no matter which half), the choppy video is gone. Very frustrating, and I hope there's an answer soon which doesn't require buying a new computer.

COMPAQ Windows XP

Hi, Did you ever find a solution? my issue is that I can't hear the music when I import a music track in a certain way.
WORKS - If I add a music track where you see it in the background in all green
WORKS - If I add a music track in all green and then move it where I want (pin it) and it turns purple.
DOES NOT WORK - if I drag a music track onto the clip where I want it to start. iMovie 11 help calls this "attach a sound clip to video". The track appears as a green bar below the video.
I've used this method several times before and haven't had a problem. I find dragging the audio to the exact clip much easier than pinning.
Any suggestions would be appreciated.
thanks!

How to move large audio files to deskop from iPhone?

How can I move large audio files from my iPhone 4S (IOS7) to my iMac (OSX 10.5.8)?
I can not use:
- iTunes (will not install high enough to this ol'mac to work with IOS7)
- cloud-servers
- email, iPhone will not mail that big files...
- image transfer program (will not work with audio files)...
- etc.
Is there any cable that will work? Can I modify my iPhone? Is it possible to move back from iOS7 to iOS6?
This is kind of a big issue for me because I make long interviews with my iPhone but now I do not know how to move the files from my iPhone to my iMac for editing and pubishing.
All ideas are welcome (except buy a new iMac)! Thanks in advace!

8 bit / corrupted audio files on re-opening a song

See the post below. I'm having this exact problem with the latest version of Logic Pro on my intel mac. Is there a solution for this mentioned somewhere already? Please let me know soon.

"8-bit" Corrupted Audio Files On Reload?
Posted: Aug 18, 2005 10:45 AM
A day after a recording session with my band the other night, I re-opened the song and recieved an error message "What kind of file is this?" and then another... something about the file being "8-bit" and unusable. This is the bass track from a very good session with my band and I'd like to try and recover it. Does anyone know how this happened, how to recover the file, and how to prevent it from happening in the future? Any help would be greatly appreciated.
More info: When opening the file in SoundHack, it says that it is a "Headerless" file. Setting the header to 24 bit linear and saving a copy results in an extremely distorted and unusable file, but you can kind of hear the recording in the background... sped up.

Hello and thanks to all for your replies. Oh and I did in fact copy somebody else's post. Sorry for the confusion.
I had a backup of the song on another disk with which I continued with my mixing. I am not worried about that particular song now. I am just worried that this might happen again.
About my sound/sample library, I just deleted the folders which had corrupted files and copied back from my backup disks.
Dropping corrupted file in a new .lso doesn't work. Haven't tried moving preferences yet but will do. I didn't have a mac before I bought an intel mac.
Can someone explain why this happened in the newest version when this was supposed to have been resolved in an earlier version? Isn't the latest version a cumulative one?
There's one other thing that also happened with me this week. I think it's related:
I had a Logic project open which was set at 96/24 and I had some audio done in it. I tried to open Reason rewired to Logic because I wanted a drum beat from Dr.Rex. Reason was set at 44/16. I tried to open some of the samples from my sound library. The files played just fine but later on when I checked, the folders which I went into looking for that drum beat got corrupted. In fact, it corrupted everything under root folder. It shouldn't have touched my samples at all, right? Why should this happen when I'm trying to just read samples or files?

OMG - Help! Why can't I freely move an audio track?

I'm not a novice to iMovie '11, but this is the first time I've had to sync an audio track to the video. Basically, it's a music video. The audio track is the song. I need to sync the video to the track, and the video will be cut into numerous clips. Before Apple totally screwed with the interface, I could have two audio tracks which allowed me to freely move the audio to any point in the video. And it laid out the entire "song" so that I could just keep adding video clips to it and know where the heck I was in the audio. Now when I add an audio track, it gives me a tiny clip of it - I can't extend it to see the entire thing. When I try to add it to existing video in the timeline, it only goes to the end of the video - I can't extend it or move it to sync up. It's locked in place. Am I going to have to go through and edit the audio and the video down exactly before they sync up? That's gonna take me forever. At this point, I wish I could go back to iMovie HD where I could get this down in a straightforward way. I don't get the new system at all, and I've about had it.

Sarah, I think what is happening is you are creating a 'background audio' clip. What you can do to delete that background clip first is to go to the Project Browser on the timeline and click the colored area behind the video clips that designates the audio track. When you see a yellow highlight around the whole audio section (it will be colored in either green or purple) hit delete.
Now to drag the audio clip into the timeline you will first need at least one video clip sitting there to act as an anchor for your floating audio track. Drag the audio and drop dead center on that video clip. iMovie will understand that this is fundamentally different than a background track and give you a floating title bubble you can drag left and right as needed. And depending on the length of the song you should be able to see the whole thing if you need it by using the zoom slider underneath the Project Browser window, lower right.
When you need to cut down the length of a video clip, first select the whole thing by holding CTRL then clicking on the clp. Then drag the left/right edges of the video clips where you would like them to matchup in the beat of the song. The handles on the sides can then be used to Trim Clip to selection, to shorten the length. With the clip highlighted and the selection handles dragged into postion go to Clip Menu>Trim to selection

Corrupt audio file prevents me from opening Logic project file

Hello,
I've been running Logic 8 for a couple years off my MacBook and have never encountered any significant problems of file corruption until recently.
The issue I encountered is this:
I've been producing a lengthy track in an on-going Logic project file for some time and after completing a recording session I saved and started deleting excess track copies to clean up my arrange window. Upon doing so Logic unexpectedly crashed.
After attempting to reopen the project file, it started its normal process of loading its respective audio files, but now it hangs on one particular audio file indefinitely (I'll refer to it as 'audio file x' for ease of reference), freezing and crashing Logic as a result. All of this project file's auto backup files are also incapable of being opened without giving me the same result and crashing Logic.
I have no way of opening this project file and getting at my most recent saved sequence!
I've tried removing this corrupt 'audio file x' from the project's audio folder and dragging it to the desktop, but this had no effect and I still can't open any recent version of the project file.
Older saved copies of the current project file do still open though (most likely because they were saved prior to the corruption caused by this suspect 'audio file x.') When opening an earlier iteration of the project, I get a message '1 invalid audio region found' (I assume referring to the corrupt suspect 'audio file x' that I removed to the desktop) but the project file is still able to open.
I realize I could import the audio files from the most recent version of the crashed file to an older project version and reconstruct things back to the way they were, but it would take me a lot of time and I'm hoping there may be some way to recover the un-openable project file by getting it to stop looking for this corrupted 'audio file x' on startup.
When I click 'show package contents' of the Logic Project file, I notice two items labeled 'displayState' and 'documentData.' From my troubleshooting I've come to the basic understanding that the 'documentData' file contains all the sequence data and settings for its respective Logic Project file.
I think the 'document data' of the unopenable project file in question may be corrupt because whenever I replace it with the 'document data' from an earlier Project file version, the file is able to open. This doesn't do me much good though, because it's document data from an earlier iteration of the project and I need to be able to get at the current sequence I had right before my file crashed.
Is there anyway to open a project file without letting it load its audio files? Or is there anyway I could get inside the 'document data' file to delete the reference/pathway in its audio bin to the corrupt 'audio file x' its hanging on?
Any insights would be greatly appreciated. I'm hoping there's some way I won't have to repeat a couple days worth of work. Thanks for your help!

After further troubleshooting I've realized that the suspicious audio file that prevents the project file from opening is actually not corrupted itself. I can still play the audio file in other media software like Quicktime, etc. with no problem.
This leads me to believe the problem opening the project file lies solely with the corrupted 'documentData' file.
Does anyone have any ideas about how I could somehow open this project file and delete the reference of the troublesome audio file from the project's audio bin?
Well... it really sounds like the project itself is corrupted, that's one of the reasons all project files won't load from a certain point on.
Try this.
Reboot the Mac.
Open the Applications folder and boot Logic from it's icon.
As soon as the Logic Logo/graphic window appears on the screen hold down the control key. You will see a message pop up that says something like "Launch the Core Audio Driver" there will be yes/no choice available... select NO.
Go to the File menu and selct "open" go find your project file and see if it will open. If it does.. delete the audio file in question... however.. I would also look at any plugins you recently installed and are possibly using in this project...this sounds more like a plugin problem rather than an audio file problem, but that's just a gut feeling.
Anyway, if it opens delete whatever you suspect and save under a different name.
Reboot Logic and see if it can load the project.
