HT3775 why won't quicktime play .mp4?

why won't quicktime play .mp4? I just downloaded a 1.2 gig mp4 video that won't play.

Thanks. I just found it strange that it was one of many files that I ripped from a DVD ( part of a box set of a TV series, and all the others were fine so far. Funny that this one in particular was causing a problem.

  • HT3775 Why won't Quicktime play a .mpeg file?

    I have a .mpeg file and can not get it to play.  I am so frusterated!

    Try installing Perian. It helps quicktime play lots of different formats.
    Or, try VLC. It plays lots of video formats.
    mpeg isn't one specific format. The video can be encoded in lots of different formats and still be called an mpeg. You have to find something that can play the particular codec that was used to encode the video.

  • HT3775 Why won't quicktime player work? I own Mac Book Pro with Retina Display and connote get the quicktime player to open or play quicktime movies?

    Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.  Select Preferences/com.apple.quicktimeplayer.plist. Move the .plist to your desktop.
    Open the application and test. If it works okay, delete the plist from the desktop.
    If the application is the same, return the .plist to where you got it from, overwriting the newer one.
    Thanks to leonie for some information contained in this.
    You might need to redo the View settings after an update.

  • Why Won't QuickTime Play Video?

    Hi,
    I use a Power Mac G4; run Mac OS X 10.4.11 Tiger; QuickTime 7.6.4.  Why won't QT play the following video:
    www.globalwebsupply.com/images/mdsmarttool.asx  ?

    I use a Power Mac G4; run Mac OS X 10.4.11 Tiger; QuickTime 7.6.4.  Why won't QT play the following video:
    www.globalwebsupply.com/images/mdsmarttool.asx  ?
    1) The Advanced Stream Redirector (ASX) format is not supported by QT X.
    2) The Advanced Stream Redirector (ASX) format is not supported by QT 7 without third-party support such as the Fil4Mac WMV components.
    3) Even the Flip4Mac WMV component only "supports a small subset of the ASX file format."
    On my system:
    1) Trying to play the file directly in QT X using the "Open Location..." option returns the fillowing message, "The movie 'mdsmarttool.asx' can’t be opened because the file is not in a format that QuickTime Player understands. The file may be damaged or may not be a movie file that is compatible with QuickTime Player."
    2) Trying to play the file directly in QT 7 using the "Open URL..." option returns the following message in the "Inspector" window, "Movie Unavailable."
    3) Trying to download the linked file does nothing. (Aborts action without any message.)
    4) Trying to open the URL in Safari returns the following message, "The operation couldn't be completed. A Microsof Media Server (MMS) error was encountered. (-19160) Try again. If the problem persists, contact the website administrator."
    Based on these results, it would appear that there may either be an access problem or a file type support problem.

  • HT3775 Why doesn't QuickTime play audio for some avi videos?

    Why doesn't QuickTime play audio for some avi videos? Is there a download to help resovle this.
    I am running Mountain Lion, I have also installed flipformac, divx, and vlc. They are working fine.

    You can only use QuickTime Player 7 to play that 12 year old format.

  • Why won't Firefox play mp4 from my website using xplornet satellite?

    I can play mp4's on my website using Firefox and dial in. When I try and use xplornet sattellite it doesn't see them .It will open wmv. If I use Explorer and teh satellite I can play them. Many people with different operating systems and browsers can play them.
    What do I have to add, change or do for Firefox to play mp4 from my website? We have loaded the latest Firefox and it still doesn't work. It ha sto do with the satellite and Firefox. We must be missing some plug in, add on or something else.
    thank You

    Hello,
    I think the problem is your OS. Firefox supports playback of H264 encoded video (mp4) but only where the ability to decode the stream is already included in the Operating System or in the hardware.
    This means that it will work for Windows Vista and above but not for XP since XP doesn't include the decoder.
    ''"To avoid patent issues, support for MPEG 4, H.264, MP3 and AAC is not built directly into Firefox. Instead it relies on support from the OS or hardware. Firefox supports these formats on the following platforms: Platform Firefox version Windows 7+ 21.0 Windows Vista 22.0 Android 20.0 Firefox OS 15.0"''

    I am not sure but it may work if you install the VLC plugin: https://wiki.videolan.org/Windows/#VLC_Plugin_for_Firefox_.28Mozilla.29
    If you have control over the site then I suggest using a different Video format which is not patent encumbered. The webm format is one option:

  • My mac won't read my external harddrive's videos that I took with my Nikon.  Half the videos won't play, and those are .avi files.  WHY won't they play anymore and how can i retrieve them?

    My mac won't read my external harddrive's videos that I took with my Nikon.  Half the videos won't play, and those are .avi files.  WHY won't they play anymore and how can i retrieve them?

    What exactly is your problem? Is it, (a) your Mac doesn't read your external disk, or, (b) you can't retrieve your videos, or, (c) you can't play them, or, (d) you were able to play them at one point, but not any more.
    What version of Mac OS X are you using, what app are you trying to play your videos with, what happens when you do, and what error messages, if any, do you get?

    Why won't Itunes play my music on my windows laptop?

    I was on the same boat, bud! I saw you had the exact same problem as I did and decided to come back to help you out.  On another apple discussion page, a user--Charlicharli-- posted a link to download and everything seems to be fine now.  Apparently we had to check with Lenovo.  We were looking in all the wrong places for the fix!

  • Why won't videos play on my new iPad 2 14gb? They either constantly buffer, stop and I have to press play again, play sound only etc.

    Why won't videos play on my new iPad 2 14gb? They either constantly buffer, stop and I have to press play again, play sound only etc.

    Thanks .Ralph.  The problem is only on the iPad 2only.  I have an iPad 1 as well and it never had the problem.  The only videos that I have tried are you tube and the tutorials on apple.com.  I have absolutely no problem on either of my laptops or desktop PC's.  Only the iPad 2.    I am a new Apple user, so not very familiar yet with the product, but this is an absolute deal breaker for me.  With Apple's reputation I was not expecting any such problems and it is beyond my skill set to solve it.  Very frustrating.  Again, no problem with you tube videos.  I don't watch movies, so am not a Netflix member and haven't tried that yet, only you tube videos and apple.com tutorial videos.  I have to watch those on my laptop.  Again, I found a fix to the you tube problem.  It was a link to a site.  www.youtube/html5.  html5 video player trial that you click on and once done, the videos on the you tube app started working great.  They were doing the same thing as the tutorial videos prior to that.  No such luck with the other web videos, at least the ones that i have tried. Hope this is enough info and understandable. You might check out the html5 site.  I didn't thoroughly understand why, but it worked.  You may understand it better.  I am a proficient user, but far from an I.t. Pro.  I have read Many posts with similar problems, but no simple solutions and the ones I did try didn't work.  Speed tested well.  Channel is set to auto and always different than neighboring networks, usually channel 11.  Tried disabling QOS as suggested....no good.   I am completely stumped.   Any help is greatly appreciated.  Thanks very much for you time and helpful info.

  • HT3775 why can't i play .wmv file in quicktime even after i download codec from windows? can anyone help me wit this please!!!!!

    why can't i play .wmv file in quicktime even after i download codec from windows? can anyone help me wit this please!!!!!

    Have you done the obvious things to try to fix it: quit Quicktime then start it back up again, log out then back in, reboot.
    Edit: Just read one of your later posts. If VLC won't play it, this is unrelated to Quicktime and Flip4Mac. Are you sure these wmv files are okay?

  • WHY WON\'T QUICKTIME HOME MOVIE PLAY ON TOUCHSMART

    Why won't a quicktime home movie play on touchsmart 310
    This question was solved.
    View Solution.

    Have you installed the quicktime software from Apple? There are other players that may also have the required codecs to play the video.
    That is what is required in order to play a quicktime movie.

  • I thought quicktime plays .mp4 files

    I downloaded quicktime to play a file extension with a .mp4 extension and quicktime says it wont play and there is nowhere to download nothing to make it play. How do I play .mp4 extensions? I tried downloading like 20 programs that are suppose to play .mp4 files and none of them worked.

    I have the same problem, When I download video from the net they are mp4. They would play at one time and now they don't. I have qtpro

  • Why won't quicktimes and mpegs import into iTunes?

    I'm trying to make a playlist of videos in iTunes. Several of my movies won't import when I drag and drop them. Some were created in Final Cut Pro 7 as basic MOV. One is an MPEG I received frome someone. Why won't they import?
    thanks

    Sorry, I assumed that you were shooting RAW + jpg.  What I think you are now saying is that you have a shoot in which some of the files were shot in RAW and some in jpg?  In that case, I don't know why it would only import RAW on the first go round and jpgs on the second. When I have mixed files (I shoot only RAW, but panoramas  are by definition only jpgs), they all import on the first try. In fact, even video files come in at the same time.
    If you did shot RAW+Jpg then you could either check the box, in which case you will see two files, or uncheck it, in which case you will see one (with the other hidden). But since that's not the case, that check box doesn't apply to you.
    Right.  Most of my shots are jpegs.  But on rare occasions, I want a RAW file so I hit the RAW button on the X100 and then shoot RAW for one shot.  This last import I had 10-15 RAW shots and they would not import along with all the jepgs.  This happens everytime I have mixed file formats.  Very frustrating.
    Thanks for trying!
