Quicktime is not opening .mp4 files anymore

Hi, my quicktime stopped opening .mp4 files I record with my cellphone, that's pretty strange because I thought it was a problem with the phone but I can open them everywhere but in my Mac. This happen after I updated quicktime.
Does anybody knows what could it be?
Thanls

I am having a similar problem. .mp4s are not playing. Used Handbrake to create an .mp4 file. It plays fine on every system but the one I need it to play on. Quicktime 7 won't play any video, just a white screen like it is missing a codec. I haven't had this problem before, and nothing has been recently installed that would effect Quicktime. Is there an easy way to reinstall the codecs? I've reinstalled Quicktime several times with no effect, recreated the .mp4 file several times, everything else plays fine. Any ideas?

    After recent QuickTime updates fcp and QuickTime will not open .mov files captured on my FS-H200. I put this onthe quick time thread and they sent me here.

    and NEVER do a software update unless you've got a clone of your startup drive so you can restore your system to it's working state if something goes wrong.

  • Quicktime Will Not Open Caption Files??

    I tried to locate this specific issue in the dicussion forums, but did not find sometihng similar or an answer. My apolgies in advance if I overlooked a similar post.
    I have videos that I have captioned that will not open correctly on other computers (in QT), besides my own. I have added captions as a text track and made adjustments to their positioning on the screen. When others open the QT files from another computer, you can either just see the text track and the movie is a white box, or QT will simply not open the file stating this is not in a format that QT understands.
    I noticed there is additional codecs listed with these problematic files, specifically VP6F, MPEG Layer 3, Text codecs.
    My question what is the best way for me to remove or change the codec so anyone with QT can view? I have a workaround where I place the captioned QT into Screenflow and re-export, which removes the text codec and will work fine on other computers. I just want to see if there is something I can do in QT/QT Pro to avoid this workaround.
    Thank you in advance.

    Your files are MPEG-2 and you need additional software to view them in QuickTime:

    and a different application than iMovie to convert the audio portion:

  • NEW - Quicktime not opening .mp4 files

    I posted this in another topic, but want it to be seen.

The .mp4 plays in Compressor, iTunes, and, oddly enough, Full Screen mode in QT player, but not in the regular mode. Any ideas?

    These are the downloads and the settings you need in order to view/hear pretty much everything:
    Assuming you already run OS 10.4.9 or above and have Quicktime 7.2, and are using Safari 2 or 3, download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:
    RealPlayer from http://uk.real.com/player/
    Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
    Perian from http://perian.org/
    Adobe FlashPlayer from http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash
    In Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).
    In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them).
    Now repair permissions and restart.
    The world should now be your oyster!
    You should also have the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.

  • Quicktime will not open video files - QuickTime couldn't parse it: -2048

    I just purchased a new Sony handycam so that I can make movies using iMovie. However, iMovie will not import the files from my camera and although the files show up on the drive as Quicktime MPEG files (with suffix MPG) neither Quicktime or iMovie will open the files. iMovie gives an error message saying "Quicktime couldn't parse it: -2048"
    Can anyone help - I really want to open the files in iMovie so that I can make videos and I'm worried that my expensive new Handycam is a worthless purchase!
    Thanks in advance...

  • Quicktime does NOT open mp4

    Im running Mac OS X Lion 10.8.4.
    When I try to open an mp4 or mv4.
    Since these file types should be compatible with both QT 7 and QT X players (assuming the MPEG-4/AAC and/or H.264/AAC data was not encoded using a proprietary or hybrid codec and the files are properly terminated), either something is wrong with your computer or the file itself. Post or upload a sample file for examination.

  • Quicktime won't open .mov files anymore

    I have a MacBook Pro with OSX 10.5.8 and Quicktime Player 10.2. Since upgrading to OSX 10.7, I can no longer open most video files I have collected with a .mov extension. These files open fine in Real Player or VLC.  Quicktime, however, won't open it with a message that a required "codec" isn't available. I've noted that some in this situation have found Quicktime Player 7.6.6 in the Utilities folder. I don't have a Quicktime Player in the Utilities folder.

  • Can not open PDF files anymore

    My computer recently installed the latest Adobe reader and now I cannot open any PDF files, it looked like it is going to open, then closes. Does anyone know what the problem would be?  I do have Norton 360 on my computer.

    What is your operating system?  What is your Reader version ("latest" means nothing)?

  • E50 not opening zip files

    I have an e50 and a week ago I updated the software of the phone from the Nokia web site. The current version is 06.41.3.0. I am not sure but since then my phone does not open zip files anymore. When opening them from an email attachment it says the object is not supported. When opening them from the phone or mem. card it says unable to open. When trying to start the Zip Manager app. - nothing happens, just throws me back in the office folder.
    Does anyone knows what is going on. Is there something wrong with the phone or just I do not know haw to work with it. All the rest supported files I can open /pdf, doc, xls, ppt/
    Thanks in advance
    Vassil

    A .zip file should open in StuffIt Expander when you double-click it; if not, open the StuffIt Expander application in your /Applications/Utilities/ folder and drag the file into the open StuffIt window. If you don't have StuffIt Expander on your computer, you can download it for free.

    I have the same problem. I'm using Mavericks OS and latest iMovie. Both downloaded last week. I save the movie into File (as directed) and  QuickTime

    I would like to be able to edit MP4s in CS5.  I can not open the file. What am I missing?

    According to the publisher For GoSystem Tax, the 32-bit version of Internet Explorer 8, 9, or 10 is required.  Which means it can't be accessed from an iPad.  This seems weird.  I would recommend you contact the publisher.

    But again, it would be better to restore. Also, 3rd party software does not always work flawlessly.
    To fix the error that came up, along with getting your music to show back up properly (without the risks of 3rd party software), you need to restore your iPod. If all of your music is on your computer/in iTunes, you won't loose any of it.

    If the iPod was just not showing you the songs even though they are there, the first option would be better. However, since you are getting the chkdsk error, you should/need to restore your iPod.

  • Quick time player 10.3 won't open .mp4 file

    I purchased an .mp4 file, downloaded it and tried to play it.  QuickTime Player 10.3 opened automatically.  QuickTime Player error message appeared stating that the application could not open the file.  I went to the Apple Support page that lists files that QuickTime should open and .mp4 was right there on the list.  The file appeared to try to "convert" into something else and then disappeared from the screen (when I clicked on "Tell Me More").
    Any ideas on how I can play the file?

    Try with vlc, if this doesn't show your video them the file may be corrupt.
