Some movie files will suddenly start to lag or stutter?

Any idea why some movie files will suddenly start to lag or stutter?
You start playing a file and all is ok, but then about 2 minutes in it starts to play up.
If you pause it and then press play again it will be ok for about a minute then play up again.
I thought it was down to wireless or USB cable issue, but still happens when I copy the files to the hard drive. The files are ok if viewed on a PC.

Hi
Can you post more info for better understanding?
Obviously you have desktop PC and want to watch movies from....where? YouTube, saved on HDD, external HDD?
Are video files in HD or compressed video files?

Hi
Did You ever use - iPhoto ?
Did You may be direct iPhoto to a different Photo Library
As iMovie tries to find the appropriate photo library - it can get lost if iPhoto direct it into a Library on a not connected external hard disk or to a strange location - And iMovie HANGS.
Do - When no other program is running that might interfere
• Start iPhoto - BUT NOW KEEP alt-key (option key) DOWN during the full Start-Up process
• Now iPhoto let's You select Photo Library
• Select the one in Your Account / Home folder / Pictures ! !
• Then iPhoto should start up OK
• Now Quit iPhoto
• START iMovie
Does it still hangs - then I would suspect - iMovie Pref. file
If it Run's OK - Then HURRAY !

Quicklook suddenly not working on some .mov files & most .m4v

Hi,
I'm kind of stuck here and could use some help.
Recently, I can no longer get a Quick Look view on some .mov files and many, if not all, .m4v files. They were working when I installed Mountain Lion and perhaps up until the first update. I'm not sure if this is related to the 10.8.2 update, but maybe.
What I'm noticing is that .mov files generated by Adobe After Effects, or even those perhaps converted from other formats usings MPEG Streamclip are no longer able to be Quick Looked. Also, .m4v files that were for certain converted by a 3rd party app are no longer viewable via QL. The files are not corrupt and open fine in Quicktime.
I followed the advice in this article: http://reviews.cnet.com/8301-13727_7-57355404-263/fixing-quick-look-issues-in-os -x/ with no real difference. I've also repaired permissions.
Any help or tips would be greatly appreciated. Am I missing a QL plugin?
Thanks,
Antonio

Mov file will not open on Premiere CS6 for Windows

I am a student working on a project that I started in university on an Apple Mac desktop. I decided to carry my project back home to continue with it on a laptop which is Windows...however the Mov. files will not open up on premeire pro and it is really frustrating as I have done a lot of work. How can I import these videos without losing any work or having to start again?

Premiere Pro CC freezes when processing some .mov files

I'm new to Premiere.
I just got some .mov files to be edited. I'm not sure how they were created.
When I try to do anything with them Premiere freezes and I have to force it closed and then manually kill Adobe QT32 Sever.exe in order to restart Premiere.
If I can get a clip to play, the video freezes but the audio plays.
The Media Pending screen shows in the thumbnails when mousing over the clips in the bin.
Just importing all the clips into a project will freeze Premiere.
Quicktime Player plays the files ok.
Loading the files into VideoPad results in a 4 second clip. That is, every file ends up being just the first 4 seconds when VideoPad imports it.
I do not have this problem with other .mov files from a Nikon D3100.
Any suggestions would be appreciated.

Thanks for your reply, Jeff.
The MOV files are client provided. He emailed me today that he recorded them on a consumer camera that created AVCHD files which he converted to MOV through a free utility he found on line. Sigh.
Since Quicktime Player plays the individual files he didn't know there was a problem until they were given to me to assemble into a finshed piece. As the clip numbers are not sequential, I'm guessing there was a committee who looked at all the clips and chose the ones they want in the final product and only those were given to me.
He said he could copy the original files onto a DVD (hopefully he has the entire contents of the chip so I will get all the files that were created as this knowledge base article indicates).
I tried Handbrake and what I get is a split second of live video which then freezes as the audio plays out. :-( I, too, suspect the fault is in the multiple video data types.
Thanks again for your input.

Problem importing some .MOV files into Premiere Elements 11

Hello,
I am trying to import film footage into Premiere Elements 11 and am coming across a rather confusing problem. All of the footage is in .mov format and all of it was taken on the same device on the same day with the same settings.
When I try to import the footage, some files import ok, others will not import at all and I get a message saying 'The importer reported a generic error'. It seems very odd to me that some .MOV files are OK and others are not.
This same footage can easily be imported into Premiere Elements 10 and into Windows Movie Maker - which makes me think the issue is with Premiere Elements 11.
Does anyone have any ideas on this?
Thanks

What model of camcorder is your video coming from and what format and resolution is it? Did you use Premiere Elements to get the video from the camcorder to your computer?
Have you ensured you have the latest version of Quicktime installed on your computer?

Some .mov files wont work in quicktime player(10.2) and itunes 11.

Hi,i have quicktime player version 10.2 on my os x mountain lion (10.8.2).i am using macbook pro.the problem is i cant play some .mov files on quicktime and itunes 11.i can play this files with other media players such as vlc and quicktime player 7.My real intention was to create a playlist which includes some .mov formatted files on my itunes's sidebar.i have imported some files with the same format to the itunes without any problem but i cant these files.i even cant see these files in finder's preview.and also,i have tried to open this files in my wife's macbook pro,with os x 10.7.5,it opened and played well.
when i try to open these files in quicktime 10.2,the quicktime windows pop ups at the same time.it's trying to open and play files but cant.

Hi,when i use contextual menu's " get info " on .mov file,these things are written:
Dimensions:880x660
Codecs:Sorenson Video 3,MPEG Layer 3,PNG.
While I personally would like to know if the PNG track is being used for the display of a PNG image in the background or foreground or for Motion-PNG video, it probably makes no playback difference here... (I.e., if you have QT 7 Pro installed, it would be nice to get a look at the "Properties" window.) However, if you regularly export to "legacy" codecs like Sorenson or Motion-PNG, then you will need to re-enable your legacy audio and/or video codecs which are, by default, disabled for export use under Mountain Lion.
Basically, this looks like a legacy file (i.e., Sorenson/H.263 video with MP3 audio is a common FLV file codec combination). Since legacy codec support is, in general, being dropped from QT, I would normally recommend keeping both the Perian codec component package and the QT 7 player installed to handle older content which may or may not play in the QT X player any longer.
If these feedback is not enough,can u pls suggest how i can get more information about compression type and codec component of those files ?
If a file will not open in any media player, then the Finder's "Get Info" may provide the most basic information. If a file opens in a media player, then the best thing is to use that app's media information window (window may be called Inspector, Media Info, Clip Info, etc.) to provide additional information. One handy, independent, dedicated utility gor general use would be the free MediaInfo app which can be downloaded from the internet. Since most of my video content targets QT, iTunes, iPod, iPhone, iPad, and TV use, I normally prefer opening files in QT 7 Pro and examining the content as depicted in both the "Inspector" and "Properties" windows as depicted below:
And also,is there any way to see which codec components i have in my quicktime player ?
Apple "Pro" Editing and third-party add-on codec compnents are normally stored for global use in the "~/Library/Quicktime" folder. Here is the configuration for my system:
System, add-on AppleProResDecoder, and older QT 7 MPEG-2 Playback Component are all stored for blobal use in the "~/System/Library/QuickTime" folder as seen here:
Codec components can also be installed in similar folders for "local user" use in each user account but this practice seems to have generally ceased with the release of Snow Leopard.
Suggest you check to see if your wife's third-party configuration includes the Perian codec component and your system does not since this is the codec which my sytsem defaults to for the playback of Sorenson/MP3 MOV content as seen here:
Good Luck!

My iPad mini is unstable. It will suddenly start jumping around apps and go to the search feature where random keys flash. I've restored it to factory twice. No change. Any ideas?

My iPad mini is unstable. It will suddenly start jumping around apps, flashing, won't stay on app I was using. I've restored to factory twice. No luck. Any ideas?

I have had exactly the same problem now with two mini iPads. Everything was tried; 1) restarting; 2) restoring factory settings etc. NONE worked. Eventually Apple agreed to replace it. I have had the replacement now for two to three months and exactly the same thing is happening again. So off to Apple tomorrow to get another replacement.
I am quite a heavy user of the iPad so wonder if this is something to do with the fault.
It is so frustrating as sometimes reset works, and then after 10/20/30/40 minutes (you pick) it goes unstable again.

Quick time movies (.mov) files will not play in Iphoto 11.

Quick time movies (.mov) files will not play in Iphoto 11. The thumbnail of the movie shows but when selected only a exclamation mark appears. I rebuilt the library, thumbnails, permissions etc. I also found the movie files in the iphoto database intact and working. Please advise.

You're welcome.
Well believe it or not, that's exactly what the exclamation point means. Search the forum. I've been doing this a while.
Next, I have no interest, commercial or otherwise in Library Manager, I have no shares in the company that makes it. I didn't make it. It's not my software. You could give those guys a million dollars and I'll get nothing from it. I and other expereinced users have recommended it thousands of times on this forum for this problem. Amazing how often it works. Of course, a quick search would have told you that already.
Another: Believe it or not you can use the Rebuild Function of Library Manager for free. You don't need to purchase it for that purpose.
Y'all have a nice paranoid day now.

+I've tried some suggestions online, but most suggest that the problem is with available media--I don't think that's my problem. Any suggestions?+
You don't have enough media.
Move your IN point a few seconds into the clip, and then drop it into the timeline.

Exe file will not start using a Measurement studio 2013 component

Hello,
I use Meausrement studio 2013 with visual studio 2012 and vbnet on windows 7.
On a new project (windows form application), i use a form and a ScatterGraph component. I compile, no errors and it works fine.
Now, i try to start this application on a another Windows 7 station. (The framework 4.5 is installed on its station).
The exe file is in a directory with the natrional Instruments dll files.
The exe file will not start, no errors.
PS: Before, with Meausrement studio 2010 and visual studio 2010 all worked fine.

Hi, virgule
It sounds like you are using the "Publish" feature in Visual Studio (a.k.a., ClickOnce) for deployment, is that correct? If so, unfortunately ClickOnce is not supported by Measurement Studio components.
If you are looking for a good way to deploy Measurement Studio applications, I would highly recommend upgrading to Measurement Studio 2015, which ships with Measurement Studio Installer Builder. You can read more about this here: http://www.ni.com/white-paper/52669/en/
If you cannot update to Measurement Studio 2015 and are using Visual Studio 2013, NI recommends using WiX for creating your installer. More information on WiX deployment can be found here: http://digital.ni.com/public.nsf/allkb/764B727C9BD2C4C686257C970053D059

Hello. I have some .mov files that I am able to open with Quick time on my pc but not on my mac. I even tried downloading quick time 7 but still no progress. Is there anything else I can do?

I can not open my.mov files on my mac. I would like too. I use to b able to look at them but for some reason i can not. I tried downloading quick time 7 but i have had no luck. Is there a way for me to open them? I just finished updating my system software so maybe that had something to do with it? Please help.

drrbr1,
Mavericks changed how media was handled on OS X. Apple moved away from the old Quicktime frameworks (that were started in the 80's IIRC). Now the OS uses AVFramework. It is why Quicktime X (QTX) & Quicktime 7 (QT7) can play different formats.
QT7 used a series of codec plugins (encoder/ decoder) to add support for formats that Apple never supported (like DIVX, WMV, Ogg audio etc). Many users installed plugins like Perian to add these codecs via a simple installer. Perian may still work on QT7 apps, I haven't tested Perian on 10.10. Perian is clearly out of date & abandoned now, see perian.org or see the site of the old codec.
AVFoundation & QTX has no ability to add extra codecs - you get support because the format is correct for AVFoundation to play, you get a dialog that converts the movie or the third option is that AVFoundation can't convert & simply chokes & doesn't allow playback.
Apple have nothing to fix. The reason the movies don't play is because the new framework uses 64bit for everything. The older codecs are not 64bit & since Apple didn't write those codecs they won't fix them either. It may seem like I'm apologising for Apple, but it isn't entirely their fault, things move on.
I'm afraid you need to work out what codecs you have contained in the files (.mov is just a wrapper around the data - the codec is the key to reading the data). mediainfo can help with that
https://mediaarea.net/en/MediaInfo
It will list the details of the codecs - from there you need to find an app that will convert to a supported format.
It sounds like you have a sound format that is not compatible with AVFoundation - that means all apps the rely on AVfoundataion no longer play those files (Finder & iMovie use AVFoundataion).

Mov files will no longer play -how to convert them to a playable format?

Okay, I read Steve Job's "Thoughts on Flash". Fine I get it.
So how do I convert an older Quicktime, flashbased mov file to something playable?
I have a mov file I need for an assignment for school and I been trying for a month to convert it to something that I can listen to. (It's a quicktime mov file but it only has audio.)
I've been trying to convert it on a PC since most of the programs I read about for file conversions were PC only programs. Six tries no solutions. (See my posts and requests for help in the PC Quicktime area of Apple discussions.) All give error messages and say they cannot convert the file.
So... are there any format conversion programs (free) for Mac that will convert this file to something playable? I have the ibook G4 with 10.3.9 I can try on. (The G4 tower just died - power supply is toast)
I am so frustrated and running out of time. Thanks for any ideas or help.

So let me see if I understand this.
I would attach an external hard drive to the computer via usb.
I would put a copy of the OS 10.3.9 on the external hard drive with an install of Quicktime 7.2 (still flash capable)
Then use a sound recording program to record to a different format.
I didn't know you could successfully have a second OS on an external drive without problems. Anything in particular to be careful of, or to do or not to do? Do I have to start up the laptop with the external drive disconnected and then connect it after start up?
These won't fight with the current OS on the laptop? or the current Quicktime install on the laptop?
Question: can I remove the hard drive from the just expired G4PowerPC and put it in a case and attach it by usb to the laptop? I'm pretty sure it's Quicktime version is 7.2 and I have a paid for copy of sound studio on that hard drive. The G4 hard drive is used to being the master drive vs the slave. Do I have to move the jumpers or is there something else I have to do? It's got OS10.3.9 and OS9 on it.
I don't know if my mov file has any enabled clicks or not. How would I know or find this out? What would this look like or how would it behave?
Thanks for the idea.
