IMovie Project losing audio & freezing video

About 2 weeks ago I created an iMovie Project with clips imported from a Sony Handycam HDR-CX500V. Everything worked like a charm and I even shared it via my MobileMe account. Just yesterday I tried to view the project again in iMovie and after several minutes it comes to a transition and as the cursor passes to the next clip the sounds stops and the video freezes, but the cursor keeps moving through the various clips. The MobileMe version is fine. I even went back and recovered the original version of the project from Time Machine for the day I uploaded to MobileMe and the same problem exists. So it seems to be the app and not the project, any ideas what is happening?

Hi Heather,
Sorry to hear you are having problems with iMovie. I generally don't have any issues with it (touch wood).
Have you tried removing any transitions that may be causing the problem. I'm assuming that you are seeing the same issues as the original poster. If that helps, try introducing different transitions until you come across any that cause the freezing problem.
Try setting up a new user account and running your project under that user. User accounts can sometimes become corrupted, just like preference files. To set up a new user, go to System Preferences (should be in your Dock) and select Accounts (under the System heading).
Also, you may have something installed that is in conflict with iMovie - it could be in your Macintosh HD>Library>QuickTime folder. Look for items like Perian, Flip4Mac or DivX on your system. Sometimes 3rd party components/add-ons/plug-ins for QuickTime can cause issues. But I'm no expert in this area!
Are you using an external hard drive to store your Events and/or Projects? If so, this must be formatted as Mac OS Extended (Journaled). To check the format, in Finder right-click (Control-click) on the hard drive's name, then select Get Info. In the window that opens you will see "Format" listed. If you need to reformat (using Disk Utility) be sure to back-up the disk first, as reformatting will erase the drive's contents.
Give these things a try Heather. Let us know how it goes.

Losing Audio in Video Conversion m2ts mp4

I am using a video importing device and software that creates a "m2ts" file.   I can play the created "m2ts" file perfectly using VLC.
However, neither QuickTime 7 or QuickTime 10.3 will play this file.   When I tried to use MPEG Streamclip I was presented with a pop-up suggesting I need to purchase an additional plug-in, (which I am happy to do). It suggested I go here to purchase. http://www.apple.com/quicktime/mpeg2
I tried that, but was redirected here http://www.apple.com/quicktime/extending/components.html
I have no idea if the software I need is at this redirected website.
The plot thickens.   The importing software has the ability within it to convert video file to a mp4.   I tried that because I have found mp4 to be more compatible.
Unfortunately, I lose all audio (the video is perfect) when I try MPEG Streamclip or VLC. With QuickTime 10.3 I get perfect audio and video. So, I drag the mp4 file into iMovie 06 (aka iMovie HD) and it begins converting into something. When the conversion is complete the audio is gone!
I have dumped many mp4 files into iMovie 06, and never had a problem until now.
Thanks for reading, suggestions appreciated.

I thought I would report my progress. ( I have sound now, BUT !! )
I purchased a video conversion program from the Mac App Store.   It is called “AnyVideo converter HD". It is well reviewed.
So, I dropped in my "m2ts" file. I set the conversion to "Computer MOV 720p HD". "AnyVideo converter HD" converted a 1 minute video in about 15 seconds to a "mov".   The converted file had excellent picture quality and sound, it played perfectly using QuickTime.
Then the trouble started. When I dropped this 60 second clip into iMovie 06 (set for 720p) it's conversion process took 35 minutes ?!?!   The result was flawless! However, a two-hour video conversion would not be complete until about the time Capt. Kirk joins Starfleet.

Imovie opens only audio, no video .AVI clips Samsung camcorder

I am using the SD storage with USB transfer on the Samsung SC-D363. the window opens and the files transfer fine, but video is missing. Maybe only DV tapes can be used to tranfer video to my mac?

I can't find any reference anywhere to a Samsung SC-D363 ..perhaps there's an error in the model name or number.
Any device which creates videos on SD storage should automatically copy them into iPhoto when you start that up with the device connected via USB.
Or, if that doesn't work, connect the Samsung and look in your Mac's 'Applications' folder for the 'Image Capture' program: that should recognise the camera and import from the SD card.
With either of those methods - but especially with iPhoto - any movies which are playable in iMovie can then be imported from iPhoto.
iMovie can play MPEG-4 videos (..mini videos which have been saved in MPEG-4 format ..see your Samsung's instruction book to find out what format the camera uses for movies..) and it can play some .avi and other movie formats. In some cases, though, you might find that the video plays OK, but there's no sound. In those cases you could try playing the movie(s) using the QuickTime program.
If your Samsung is a normal DV camcorder which also saves mini-movies to the SD card, then you'll be able to use a USB cable to copy the mini-movies, as described above, but you'll need a FireWire/DV/i.Link (different names for the same thing) 4-pin-to-six-pin cable to copy normal DV video from the camcorder to your Mac.

HDV imovie projects lose audio sync when burned in idvd

I have 80 min. HDV projects from imovie sent to iDVD, after burning them onto dvd they play fine then lose audio sync after about 60 min. or so.....

Painful in iDvd to do interviews when they happen to fall over the 60 minute mark, isn't it?
If it's of any consolation, it's more reliable in Apple's FCS2 / FCP => DVDSP.
Toast might be another option worth looking at....
Good luck on this.

1:59 project - unequal audio and video lengths - unplayable DVD

I don’t know if this is a Final Cut Pro problem or a DVD Studio Pro problem.
I have a Final Cut Pro project that runs slightly under two hours. I have successfully rendered this project several times in the past (using Compressor’s 120 minute best quality settings), and successfully used DVD Studio Pro to burn playable DVDs from it.
My most recent version of the project increased in length from around 1:57 to 1:59:15. This time, when I rendered the project, the resulting audio file (.ac3) was several minutes longer than the video file (.m2v). The extra length at the end of the audio file was occupied by a repeat of a piece of the audio from earlier in the project. The Final Cut Pro project does not have this extra audio at the end.
Because the project length was so close to 2 hours, the extra audio caused the audio file to exceed 2 hours in length. Since I didn’t actually need this extra audio, I tried to work around the problem by shortening the audio track in the DVD Studio Pro timeline window: that is, I dragged the end of the audio track in the timeline to shorten it so that is was the same length as the video track. I then burned a DVD, but a message in DVD Studio Pro’s log window said that the file was “too long for the selected media”, and indeed the resulting disk was unplayable.
My questions are:
1. What could cause this extra audio to appear at the end of the rendered audio file?
2. How can I either (a) prevent this from happening, or (b) work around the problem and successfully burn a DVD?
In the meantime, I’m trying to work around the problem another way by rendering the Final Cut Studio project using Compressor’s 150 minute best quality settings.
Thanks,

First, yes resample the narration to 48k 16 bit. You will probably be able to reconnect to the resampled files. Usually works for me. That's a simple fix and will probably solve the problem. If it doesn't, you can try to change the codec (compressor) in the sequence settings to prores 422HQ, fully render and see if that solves the problem.
Wait, just reread your original post. Export from fcp using file: export: quicktime movie NOT quicktime conversion with current settings. If that works without synch issues, use compressor to convert to prores.

Only iMovie project or any Quicktime video file in video track ?

Hi,
it's a question before to buy iLife06 :
GB3 has a video track : is it only for iMovie film ? or can I put any kind of quicktime video file ?
thanks,
Vinc26

Just a couple. I don't even remember what codecs they were. I had some movies I had downloaded off the internet and they worked fine.

Moving Aperture libraries while keeping iMovie project video links intact.

I am in the process of moving my Aperture libraries off my internal drive to an external drive. The problem I found is that by do so, my iMovie projects that were using video clips from the Aperture libraries now have broken source links. I have all my video clips managd by Aperture, not referenced.
The way I moved the libraries was simply drap the library files to the new desitination. I can see the original clips in iMovie's event library after the move and thumbnails are generated; but my project links are not updated.
My question is that is there a proper way doing this correctly so my iMovie project links are still intact after the move? Thank you in advance for your helps.

I have exactly the same question as the OP. I've been into digital photography for a while, and have been using Aperture for a short time, but have JUST started to shoot some video for fun. Video goes into my Aperture library, but I'm just using iMovie to mess around with the video. I export short clips to YouTube for the family to view. Eventually, I'll put these projects on DVDs and I know I'll have to delete them from the Aperture library for space reasons.
How are people handling this? Should I just move the video directly to an external hard drive, for example?
Thanks.

No audio from videos that I drag to a project?

I'm trying to make an iMovie project of music videos, but I just dragged a .mov file onto the iMovie project and while the video loaded successfully, it doesn't have any sound. Is the file format? Or something in iMovie?
Thanks,
John

Hi John
Play Your .mov file with QT-player.
- plays OK then save it as streamingDV and import this (may be You need
the pro upgrade of QuickTime to do this)
not playing OK -
- Did You change the name on the .mov file ? restor original name and retry.

I'm trying to record audio and video simultaneously using iMovie and an external mic and the computer is picking up the audio but when I replay the video there is no sound. Any ideas?

Can't get iMovie to record audio and video at the same time using the built in cam and an external mic.

iMovie works best with uncompressed audio. If your track is MP3 or AAC, you may get better results by converting your track to the AIFF format and then using that in iMovie.
You can do this in iTunes. Go to iTunes/Preferences and click the General button. On the General page, click the Import Settings button. Choose IMPORT USING: AIFF ENCODER.
(note: remember what you changed it from so you can change it back later, before you import another CD)
Now, in iTunes, select your track. Then click FILE/CREATE NEW VERSION/AIFF VERSION.

Updated FCP 5.1 to 5.1.2 - Audio and video now out of sync

I just noticed in my software update that FCP needed to be updated. So I updated the program.
Now when I open exisiting projects the audio and video are out of sync even though they appear perfectly in sync in the timeline. Has anyone else had this problem? The problem also persists when cutting clips in the timeline. I will use the razor tool to make the cut and I cut the clip on a ceratain frame in the timeline and then in the viewer the clip was really cuts a second or two later. Does anyone know what is going on?
Very furstrating to say the least. Any help is much appreciated.
Thanks,
Clay

I am still wondering why you're recommending that I use an external drive for this project.
Because the internal has more than enough to do running Mac OS X and the applications. It is constantly writing files. While DV video is at the lower end of the scale, it is still asking a lot of the drive's read and write head.
I always used external drives, but we had many problems with delays and processing problems.
At the very least, you should be using FireWire external drives. USB is no good for video as it delivers data in packets, not the sustained stream that video needs. The drives must also be formatted as Mac OS Extended. Windows FAT 16 of FAT 32 formatted drives have file size limits of 2 and 4 GB respectively. Anything larger is segemented and can cause problems on a Mac.

How can I incorporate several video and audio clips into one iMovie project?

Hello all. Basically, I'm trying to solve a problem before it becomes one. I'm going to put together a short iMovie project for a thank-you dinner. Several people from out-of-town will not be able to make the dinner. I want to give them the opportunity to "speak" by having them put together a short video or audio clip. I then need to gather up all the clips and put them together in one iMovie project. I guess I'm looking for some assistance in terms of format, what types of files/formats to use, etc. I've done a few movies (mainly from still pictures -- glorified slideshows with music). But, I'm still a relative neophyte when it comes to the computer world. Any assistance would be greatly appreciated. (feel free to point to a "How to " tutorial if there's a good one out there).
Thanks.

your problem will not be the process of 'glueing stuff together'
follow advice given here
http://www.apple.com/support/imovie/
under 'Getting started' or follow the 'Video' tutorials ...
the real task is, to make all clips readable for usage in iM ...
before making you a technician on video-codecs:
download and install the free tools Mpeg Streamclip and Perian.org
you have to relaunch your Mac after doing so...-
BEFORE adding any of your external sources into an Event, use Streamclip to manually convert to DV, or if source is HDef, to Quicktime/Appleintermediate.
the resulting files should import flawless into iM, proceed as usual.
iM 'swallows' a lot of formats, so it could be this manual conversion isn't needed ...
don't hesitate to come back here, if probs occur ...

Scrubbing audio cuts out while editing iMovie project

Hello,
I put all of the clips, nearly an hour, in the project, and am editing just by deleting what I don't want. I keep losing audio while scrubbing. Would having less video in the project window fix that? It came back just now by restarting iMovie, but cut out again.
Thank you

Hi
and welcome to forum
*No audio on DVD disc.*
Most common origin.
1 Imported audio from iTunes.
• In iTunes copy out as an audio-CD .aiff
• Use this in Your movie project
2 Strange audio formats like .mp3, .avi etc.
• Change them to .aiff. Use an audio editor like Audacity (free)
3 Main audio is set to off in System Preferences - Does this by it self - Don’t know why
Cheque Audio-Out resp. Audio-In
4. Ed Hanna
Had the same problem; some Googling around gave me a kludgy, but effective fix
Downgrade Perian from recent versions back to version 1.0.
That worked for me, and so far I haven't encountered any deficiencies—except it takes more advanced versions of Perian to enable QuickTime to handle subtitles in .srt format—that I have noticed.
5. GarageBand fix.
In this set audio to 44.1 kHz (Klaus1 suggestion)
(if this don’t work try 48 kHz - me guessing)
Before burning the DVD.
• Do a DiskImage (File menu and down)
• Double click on the .img file
• Test it with Apple DVD-player
If it’s OK then make Your DVD.
Burn at x1 speed.... (or x4)
• In iDVD 08 - or - 09
• Burn from DiskImage with Apple Disk Util tool
• OR burn with Roxio Toast™ if You got it

Once I finish an iMovie project and I publish it to various destinations (Dropbox iTunes YouTube etc) do I need to keep the original raw video on my MacBook or can I archive it to an external hard drive.

I have now finished 3 iMovie projects and have learned how to prepare them for sharing through various media like Dropbox, iDVD YouTube iTunes etc. but I now have produced a huge number of related files which are filling up my hard drive to the point that I can't import any further raw video until I archive or delete many of these files.
What files do I need to keep on my MacBook in order to be able to keep these various shared locations functioning, and what should I delete or archive?

iMovie works best with uncompressed audio. If your track is MP3 or AAC, you may get better results by converting your track to the AIFF format and then using that in iMovie.

No audio with copied imovie project

I copied my imovie project from my time machine backup to another my mac mini. I put it in the imovie projects folder and I can open it up in imovie, but the audio isn't playing. It seems to be there. I can see the green area around my video and see the names of the songs, but I can't hear anything. The volume is on. I can play songs from itunes.

I'm trying to help a teacher with an iMovie '08 problem and this seems to match the problem we are experiencing, but I don't understand how to implement the answer given. (I'm a newbie to iMovie '08 so please forgive the basic nature of this question).
This user's iMovie project is in /Users/kate/Movie/iMovie Projects.localized/Blah Project
The audio clips are showing (and some have two layered audio clips: narration and background music).
One of the audio clips does play, but I can't see any settings difference between the ones that don't play and the one that plays. I'm assuming it is because the audio files are missing (as the answer was above). But where do I find out what relative path the project is expecting? And how might I find the missing sound files? (I have no idea how this project was created or where the user might be storing things in a non-standard way).
Basically, I need more detailed instructions on how to get the filenames of the clips and the relative paths so I can copy the correct things where the need to go (if this is indeed my particular problem).
Thanks for any assistance!

Can't burn imovie with idvd & can't keep the audio and video clips to ancho

Two questions:
I've been working on a series of short digital stories in iMovie and have been trying to put them on a dvd. Using iDVD wasn't successful. Couldn't get them loaded into the map on the DVD theme page. So I dragged finally gave up and dragged the iMovie filesinto the DVD icon on my desktop and burned them. But now I have to drag the iMovie file from the DVD onto the harddrive before I play them.
I would like to have all of the short movies in one DVD.
I would also like to have one longer iMovie file but I'm having a devil of a time making all of the files, audio, video, photo, etc. stay in place while I'm working on each section. Perhaps this isn't feasible?
With thanks for any help you can give me. I'm a novice at this program but enjoying the challenge.
I'm using a borrowed machine...2 GHz G5 with 2 GB DDR SDDRAM
Powerbook G4 Mac OS X (10.4)

Were you dragging the project file into the right place? Try a simple theme like the Portfolio Colour theme under the iDVD3 collection. By the way, the simple thing first, I hope you were using iDVD5 not iDVD4.
There can also be problems if the iMovie projects were created in iMovie4 and converted to iMovieHD. If this is the case load each one again. Make some simple change, undo if you wish, then save again.
In any case try using file > Import and note what happens. I think this (old fashioned) way is easier than gragging in the projects. You can tidy them up later.
