Choppy Audio in iMovie Transitions

I'm editing some video for a keynote. I am putting three different movie clips together and trying to use Transitions. Every time I drag a transition between two movie clips the transition audio is very choppy, sounds like crap. Anyone else experience this? Fix?

Andrew replying to another Andrew
I "think" I figured out why when you apply the transitions the audio becomes choppy.
I was just doing this today as well. My video was recorded in 720i on my camcorder, but when I was importing it into imovie I chose the quicktime format to edit my video. So I think it was because imovie had to compress your higher quality video and that's when the sound and transition failed to work together.
So I realized that if I chose the format 720i to edit my video (matching the quality that it was recorded in) there were no audio issues and you do not have to extract the audio from it.

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.

IMovie moving audio clips when transitions are added

iMovie moving audio clips when transitions are addedI have some video clips that need simple fades to black added at the end. However, whenever I add the fade out transition, iMovie does something insane. Instead of the last two seconds of video fading to black and the last two seconds of audio fading out, it seems that a random two seconds of audio from elsewhere in the clip is tacked onto the end and faded. This problem is nuts and I am having no luck finding a solution. Does anyone have one? This has happened with other transitions, but I’d settle for just getting a fade to black to work properly. Is this only a problem with Intel machines?

The problem that you describe has come up frequently on this forum. There are lots of things people have tried, but no solution has been found, other than the workaround of extracting the audio, as Klaus 1 mentions, and manually adjusting the fade out. Some feel that it is an intel machine problem, but that is not clear.
For more information on this issue, try using the search function of this forum, typing in "audio echo with transitions", or some other appropriate search words. You might find of interest the information contained in the following post:

TS2289 Audio in iMovie 11 files but missing in sections when shared to iDVD. The movie and audio plays fine in iMovie but my burned iDVD movie is missing some audio .

I imported a movie into iMovie 11 from a Canon Vixia HFR 300 SD card with no problem. I have a new iMac running OsX 18.8.4 I think. I added chapter markers and shared it with iDVD. And burned it to a DVD. Towards the end of this 30 minute movie the sound just stops. I do remember some screen came up when I wanted to burn DVD that said something was wrong with files but I couldn't figure what do to fix it and allowed me to continue. Any ideas?

Hi
Either the problem is in iMovie or in iDVD
two notes
No Audio in iMovie
Most common origin is use of audio from iTunes.
Work around -
• Select needed audio to one new playlist
• Copy out this as an Audio-CD .aiff (not .mp3)
• Use this in the movie-project
Other origins are
1. strange / alient file formats as -
• .mp3, .avi, .wmv etc
• Convert them into .aiff 48kHz 16-bit and use this
2. the Mac is set wrongly in regard of midi -
• Close iMovie and other programs
• Start GarageBand
• Make a new GB-project and play some notes
• Close GB and Save
• Now try iMovie again
3. No audio when playback in iMovie 1 to HD 6.
a. in iMovie pref. - deselect ” Playback via Camera”
b. in System preferences - see that Audio out is not set to zero. Mine often does this
without me knowing why.
4. iMovie’08 & 09 & 11
• Toggle audio-scimming by cmd-K
Stuttering audio and video
1. FileVault is ON - Turn it off
2. More than 50 audio files in a movie-project
Mix down to one audio clip
3. Project is stored on one (USB) external hard disk - should be a FireWire one
4. the External hard disk is not Mac OS Extended formatted - but
UNIX/DOS/FAT32/Mac OS Exchange and this will not work for Video.
5. To little free space on internal boot hard disk.
I go for a minimum of 25Gb free space when project is imported and edited and this goes for
4x3 SD Video. For 16x9 HD my guess would be about 5 times more at least.
Neither Mac OS, iMovie or iDVD can address any other hard disk than the boot drive for it’s
scratch files. (Unlike Final Cut Express/Pro where You select scratch disk/s)
6. Network storage - DOESN’T WORK
No audio on DVD disc.
Most common origin.
1. Imported audio from iTunes.
• In iTunes copy out as an Audio-CD .aiff (Same as played on standard Stereo CD - no .mp3)
• Use this in Your movie project
2. Low - Free Space on Start-up/Boot/Internal/Mac OS Hard disk makes it hard for iMovie to work as intended.
Down to 1.3 GB and it doesn’t work - especially audio don’t migrate over to Media Browser
(iM’08 & 09)
3. Material in iMovie’08 & 09 - Shared to Media Browser and here selected as Large
large.m4v. It silenced out this project in iDVD. By making a slight alteration - provoking it to ask for a new Share/Publish to Media Browser and here selecting 640x480 - and audio was back when a new iDVD project was created including this movie.
Minuscular - - 176x144
Mobile - - - - - 480x360
Medium - - - - 640x480
Large - - - - - - 720x540 960x540
HD - - - - - - - - 1280x720
4. Strange audio formats like .mp3, .avi etc.
• Change them to .aiff. Use an audio editor like Audacity (free)
5. Main audio is set to off in System Preferences - Does this by it self - Don’t know why
Cheque Audio-Out resp. Audio-In
6. 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.
7. 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’s Disk Utilities application
•OR burn with Roxio Toast™ if You got it
Yours Bengt W

LG Tone HBS750 A2DP Choppy Audio

My setup:
MacBook early 2008
Mac OS 10.6.8 (can't upgrade)
LG Tone Pro(HBS750)
Problem:
Choppy Audio with the A2DP (stereo audio) bluetooth profile on my LG Tone Pro HBS750. It seems to have trouble connecting properly with this profile. It will connect and give good audio for the first thing i click on. like the first youtube video or the first text I select to have read to me. They work ok in stereo. but if I play another video or something else it goes all choppy. I then have to stop using as audio device and then reconnect stereo. every time i want to listen to a new audio source it doesn't want to play properly. when it connects properly it will play several audio sources at once. but if I try to do it consecutively it doesn't want to work. it's all choppy. This is only on the stereo setting. if i use mono it works perfectly. but the sound quality *****. I'm wondering if it's my OS being too old. my headset isn't broken. it plays on mono. it just seems like A2DP implementation in MAC OS 10.6.8 is not compatible with my headset.
what I've tried:
pairing the headset
disconnecting and reconnecting
Power cycling the headset.
Reboot my computer.
delete and pair the headset
exchanging the headset
pairing the headset
connecting the headset
disconnecting and reconnecting
power cycling the new headset
rebooting my computer
delete and pair again
nothing seems to work. I spent good money on this headset and want it to work. Thanks for your time.

I had the same issue with choppy audio coming out of my bluetooth headset. I had the issue with Maverick and it seemed like it just got worse with Yosemite. What I discovered is that the fix for the problem can be as simple as just replacing or recharging the batteries in all the bluetooth devices attached to your Mac. In my case, the batteries in my Magic Mouse was very low. I replaced the batteries to fully charged ones and the choppy audio from my bluetooth headset went away.
If you want to see what state the batteries in your bluetooth devices are in, just open up System Preferences and then click on Bluetooth. Each bluetooth device in the Devices list should have an icon showing the charge left in the batteries.
Good luck!
[Update]
Well, I guess I spoke too soon. It wasn't the fact that I changed the batteries in the Magic Mouse to new ones that fixed the problem. It was the fact that I had turned off the Magic Mouse when I was replacing the batteries that made the problem go away. As soon as I turned on the Magic Mouse and had it connected again, the choppy audio returned. Turned off the mouse and the problem disappeared. So, it's definitely the Magic Mouse that's the issue, at least in my case. Fortunately, I also have a Trackpad so I can always turn off the mouse when I want to listen to audio through my bluetooth headset and just work with the Trackpad. Oh, well. Sorry for the misinformation.

How to solve the choppy audio playback in Macbook Pro 2011 ?

Hi All,
I bought used 2011 Macbook Pro 2.3 GHz Intel Core i5 and ugrade its RAM to 16GB and OS to Mac OS X Lion 10.7.4. It had very choppy audio with the last version of the OS and 4 GB RAM as well. Now audios in each and every player/ browser is completely choppy.
Does Apple know about this issue ?
Is there a permanant solution for this problem ?
I don't want to loose my temptation for Macproducts bacause of these type of issue. Please help ...

But I have read now that apparently 16 GB is a bit too much for my computer to handle since certain components act as bottlenecks for whatever info/data and I don't end up utilising the full 16 GB..
The OSX will use as much RAM as it needs and is available for the given situation. 16 GB RAM will not be 'too much' in any circumstance.
Is spending $250 on a SSD worth it? Will it mean my RAM is more effective?
An SSD will allow for faster processing. Whether the costis worth for its benefits it is for you to decide. It will be able to swap data into the RAM faster but that does not make the RAM 'more effective'. As I said, the OSX governs RAM usage as required.
Or will my CPU still be hindering everything and I should just accept I wasted some money?
The CPU does not 'hinder' anything. It simply processes the data that is sent to it by the OSX within it specification limits. I am not certain that I understand your thinking here.
Basically: is it worth trying to upgrade & is it possible to get more out of my 16 GB RAM
That decision is yours based on what you feel you need and your bank account.
Ciao.

How to add audio to iMovie on the iphone?

The speak recorder on the iphone is ok to record audio. But how do I get those recordings into imovie on iphone? Its the latest imovie (2.0?) on iOS7 on iphone 5.
Thanks for any help
Erland

Thanks for looking into this. I am probably unclear here...
What I hope to do is to get audio recording fra the that speach recorder app that comes with iOS. The recordings can only be exported through mail, messages and dropped with Airdrop.
Hmm maybe with itunes in some way.
I would like to use speach recorder and then import that audio into imovie, not the audio effects that are with imovie.

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.

How to i trim audio in imovie 11

I just separated audio from an imovie clip, and now need to slice the audio in various places and and place back into the video. HOW DO I TRIM AUDIO in imovie 11. The old imovie was easy, I can't seem to find out how. Thanks.

There are several ways to do this.
First go to iMovie/Preferences and make sure the Advanced Tools are enabled.
The simplest way would be to select the frames of video in the Event that contain your audio and drag to the project. Drop it on the approximate frame (in the project) where you want it to start. A pop-up menu will appear: choose Audio Only.

Audio in imovie

when i share movie to itunes some of the audio track plays back very quiet.

If you want to increase the volume of the audio in iMovie, you can click on the audio bar below the video and drag up.

Choppy audio in iTunes 6

Only when listening to iTunes do I experience choppy audio; Whether its podcasting, songs chosen from my Library or radio streaming. I've uninstalled, then re-installed iTunes but to no avail.

try this:
http://docs.info.apple.com/article.html?artnum=93610
I've tried everything suggested, but still have the problem. My iPod Shuffle plays all the music flawlessly. All the ripped files play just fine in Windows Media Player. But the audio is so choppy as to be unlistenable in iTunes. In addition, other audio (MSN Messenger, GoogleTalk, ...) has now been corrupted and cannot be used due to choppyness. All this started as soon as I installed iTunes. I've tried updating iTunes, the sound card driver, Divix, ....
Any other ideas?
Thanks!

No USB Audio In Imovie

I have been trying to use my Logitech USB headset for recording audio in iMovie for over two days now,
I change the settings in System prefs and also in imovie but i can only record audio through the internal mic on my 24'' imac. Is anyone else running across this problem?

philaken wrote:
I do not have the "Audio Only" option when I try to Export the file. In Options, the only format I have is Linear PCM. The options I have for Export are Sound to Wave, Sound to AU, Sound to AIFF. None of them imported.
As mentioned, the "Audio Only" option is in QuickTime X (there are only 2 options: movie or audio). I'm not sure what version of Mac OS you are using, but QT X is part of the OS. QuckTime 7 provides a range of audio options, as you indicated. It's surprising that an export in the AIFF format didn't import to iMovie.
Sorry to hear you are not having any success. I'm a little vague on this, but some time ago I recall having a problem with voiceovers not playing. What I think worked was to click on the Project Library, then click on another project and wait until it loaded in the Viewer (no need to actuaaly open it by double-clicking). Then re-open your current project. If my memory serves me correctly, the voiceover then played properly in the timeline. Give this a try!
I noticed another thread where the poster is having a similar problem to yours. I'll post a link in that thread to this thread. Hopefully something here may help that user.

New Lenovo T430 Choppy Audio Playback of MP3s only in any program

Hello,
I am trying to troubleshoot a choppy audio playback problem with MP3 files on a Lenovo T430. The sound "skips" at regular internavls (about once a second). I have tried the following with no success:
1. Windows sound troubleshooter.
2. Playback through WMP 12.
3. Playback through VLC.
I was suprised to find the playback poor through VLC. Sound is fine when playing a youtube video. Any ideas on what next steps I can take would be greatly appreciated. Thank you.
Dave

Can you post the configuration of your T430? I've seen issues in similar systems configured with RAM amounts of 4GB or less and using a HDD and ExpressCache running Windows 8.
