Video Tearing - Wake Up Apple

So far every mpeg4 video that I have played in Quicktime has major tearing. From iTunes Tv shows at 320x240 24fps to 480p/720p HD Movie trailers, they all tear.
My system can play back Full 1080p HD WMV trailers, and HD mpeg2 transport streams beautifully.
When is Apple gonna pull their heads out and fix this

Again, it's not a blanket problem with QT since the videos play without tearing on my Dell with lower specifications than those of yours. So it must be something related to your specific configuration or system. The fact that other players work doesn't rule out a problem with the video drivers or with the QT installation. So I'd once again suggest checking out those possibilities, particularly the video drivers. If a driver update doesn't help, you might try completely removing QT and reinstalling.

  • Video tearing on my 24" iMac

    I have been having an issue with my 24" iMac for the past couple of months and I was wondering if you have heard of this issue before. I am getting what I guess would be described as video tearing. On occasion, and with no obvious pattern to it, I will get a weird horizontal line of noise that goes across just a certain open window, not the entire screen. I have been able to take screenshots of this, but I don't think I can post those in the discussions.
    Anyhow, it happens in Firefox, Word, Mail, etc. There does not seem to be any program that is immune to this issue, and it doesn't happen all the time. It appears to be quite random.
    I have checked the Apple Support site and the only thing I found were some old discussions about a tearing issue with previous generation iMacs. If I remember correctly, they were pretty old iMacs. Nothing about this issue in the recent past.
    The video tearing sometimes goes away if I scroll up/down the window, and sometimes it doesn't. Though, more often than not, it goes away by scrolling.
    My machine is coming up on a year old next month, so if I need to use my warranty, I need to do it soon.
    Have you heard about this issue at all? Any help would be greatly appreciated!
    My system specs are as follows:
    24" Intel iMac purchased 9/06
    2.16 GHz Intel Core 2 Duo processor
    1 GB 667 MHz DDR2 SDRAM
    I have not upgraded the hardware in anyway.
    Thanks again for your help!

    Hello lizardsrdizzy!
    Did this video tearing issue for sure just start happening, or did you just notice it for the first time? I ask only because this sounds like the known Apple/ATI issue that many of us with ATI video cards have had, but only eventually noticed.
    HOWEVER, since you do NOT have an ATI video card, I'd definitely recommend you need to pursue this flaw immediately within warranty/AppleCare.
    http://docs.info.apple.com/article.html?artnum=86823
    I strongly recommend adding AppleCare to maintain the value of your iMac, either for your own use, or for eventual resale. Considering the original cost of your setup and the still rather high cost of replacing a 24-inch display, at full cost AppleCare will be a bargain and that cost will either be fully returned to you the first time you need to use it, or when you resell your iMac. Discounted it's available from Amazon and various Mac sellers.
    If you need to get a bigger bargain, occasionally they show up, but give yourself time to find one on eBay, and refer to my recent post here:
    http://discussions.apple.com/message.jspa?messageID=4980575#4980575
    Best of luck, and please return to let us know the resolution of the matter.

  • Video tearing on iMac (Late 2006)

    Hi,
    My iMac has been suffering from what i think is video-tearing and horrible refreshrate for a week now. I'm thinking hardware problems.
    The video-tearing mainly comes up when the screensaver goes on but it's still annoying.
    The refreshrate is always bad.
    I have the iMac(late 2006) 2.16GHz with 2GB ram and the ATI Radeon X1600 with 128MB VRAM.
    What to do?

    Same Model, same problem here. Much worse i think, picture cuts in half, fonts break. Happened after some update back in March. I was away for some time not using it but now few updates later still no resolution, Display looks fine in XP (bootcamp)

  • Why is it that each time I upgrade my iPad, half of my apps won't work properly but worst of all my email won't send after the latest "patch" today, wake up Apple I am a new user and getting sick of this problems

    WHy is it that each time I get an upgrade some of my Apps won't work when they did with the previous version. I have just upgraded to v7.01 and now I cannot send email, wake up Apple and get it right as I am a new user of Apple technology and not impressed.

    That's one of the weird things.. it recognizes it maybe 10% of the time. And usually, only after I do the two-button reset. Problem is.. since it won't charge above 2%, anytime I try to do a restore or anything like that using iTunes, my device shuts off and I lose whatever progress I'd made.
    So, an update... after reading through a bunch of similar complaints (there are literally 1000's of them so there's NO WAY this isn't somehow ios7 related, thanks a lot APPLE ) I decided to try a restore in recovery mode. After 3 hours and several disconnections... I ended up having to just set it up as a new iPad, as the restore did nothing. Weirdly though... as I was doing the restore in recovery mode.. I noticed I'd gotten up to a 10% charge.. higher than it's been since September, so after setting it up as a new device, I turned it off and plugged it in using the wall charger. 2 hours later and I was up to 38%. Still not great, as my iPad, before ios7 could've fully charged twice in the amount of time it took for me to now get 28% more of a charge. And that's with a fully cleaned out device.. so that really ***** and I'm now more confused than ever.
    But I'm gonna leave it overnight charging and see what I come up with tomorrow. Sadly, when I paid $600 for it in February, I never expected to have to play "wait and see" with it...

  • [Solved] Minimalist setup with no video tearing

    Hello all,
    I maybe jumping the gun a bit here (as I still have other issues with flash and can't really test properly - see here), but here goes.
    After lots of reading and experimenting, I came to the conclusion that I really like the minimalistic approach of using Openbox and adding stuff as I need (Tint2 etc.).
    However, It also came clear pretty soon that should I want to make things look a bit nicer (that is, using some sort of composite manager), I will most likely end with screen tearing to some degree, using one of the non-opengl composite managers (xcompmgr, cairo commgr, compton).
    That is when I came across the option of using Compiz as a standalone WM, with no DE, which should solve the problem of tearing and still remain pretty minimalistic.
    Compiz, however, if I understand correctly, is going through some development "difficulties" this days (mainly used in-house by Ubuntu).
    Bottom line, my options, as I'm aware of, are:
    1. Openbox + no composite manager - should have no tearing, as minimalistic as it gets, a bit rough.
    2. Openbox + some composite manager (most likely compton) - will probably have tearing, still minimalistic, a bit nicer.
    3. Compiz 0.8.8 from repos - not sure, actually, except from the fact that I will probably not have video tearing and that it's a bit outdated as the 0.9.x line is considered stable by Canonicial.
    4. Compiz 0.9.7 (or 0.9.x should I feel adventurous) - I think I've read somewhere the 0.9.x line isn't really suited to be used as a standalone WM, something to do with the absence of Emerald (not too sure, though).
    Any input regarding those 4 options is highly appreciated, Adam.

    Doesn't matter what video card you have. OpenGL is OpenGL. Older cards support older versions of it, but it should still be enough for basic desktop effects.
    I was thinking of using a script that kills (or pauses) the composite manager if the media player window is fullscreen, since video tearing is more noticeable in fullscreen videos than windowed. Maybe adapt this script? Bah. I'm too lazy... Right now I can't be bothered with eye-candy. I used to have the tint2 clock set to right click and left click. One killed xcompmgr and refreshed the desktop and the other one started it, and restarted tint2 (for the true transparency to kick in). It's doable but I kinda gave up on it and went with vanilla Openbox + pseudo-transparency in tint2, guake and aterm because that's the only 3 programs that I wanted transparency in. And I can live without shadows. Easier on the resources too.

  • Can I stream the sound from a video running on my apple tv to my wireless speakers using airplay?

    I have living room speakers connected to an airport express and available via airplay from my computer, ipad2 and iphone which is great for playing music. My question is, can I use those speakers to play sound from videos running on my apple tv? For instance if I use airplay to run a video on apple tv from my computer or iOS device, can I have the audio play on my speakers connected to an airport express? It would be amazing to be able to use the speakers simultaneously with the apple tv as they are both on the same home sharing network. Possible?

    No. But, are your speakers only connected to the AE or are they also connected to an amplifier?
    You would need to use a Toslink cable to go from the Apple TV to the speakers/amp.
    I don't use this or know a lot about it, but it is wildly popular, inexpensive and may be of help:

  • Horizontal video tearing in xfce and ion graphics (nvidia)

    Hello all,
    I have arch + xfce running no problems, but there is significant horizontal video tearing when I play videos (in vlc or firefox/flash). I have already enabled 'Sync to VBlank' within the nvidia-utils control panel. I think the problem arises from the xfce monitor settings window that only allows the frequency output to the monitor to be 50Hz. Can someone confirm this and/or offer advice?
    Thanks again,
    DF

    Since Devotedfollower is using a nvidia ion card he will get the best results without compositing at all.
    If you want to use a nvidia card along with compiz without tearing, I found these additional steps to be necessary:
    put
    Option "TripleBuffer" "True"
    under Section "Device" in your /etc/X11/xorg.conf (if you don't have one, run "nvidia-xconfig" once as root)
    put "nvidia-settings -l" into your startup applications
    install and launch ccsm, open up the general options and look for a tick called "Sync to VBlank" and activate it
    within these general options there is a tick called "recognize refresh rate" (or something alike); deactivate it
    try playing around with the refresh rate slider (I got the best results when using the exact refresh rate for my display or something higher)
    Note that these steps are only necessary if you really want to use compiz on nvidia cards. They worked with several GTX cards for me. Don't know about your ION though.
    My netbook has an ION but it was one of the first ones. As far as I can remember it had no tearing on xfce without compositing but on compiz it had a bit tearing at the top of screen even with all the steps above.
    Nevertheless I wish you best luck!
    P.S. Tearing has always been a huge problem on Linux for me. After a lot research I found compiz being the only compositor able to almost eliminate tearing. So the only choice for nvidia users to get rid of video tearing is either to use no compositing at all (which results in teary desktop graphics) or to use compiz along with vdpau...

  • Video "tearing" on monitors

    I am using Premiere CS5.5.  I have a GTX 460 card with the MPE GPU acceleration turned on.  I am using the DVI output from the card to my GUI monitor and the HDMI output to a second computer monitor (Samsung - supposedly hi-def, though I know this is not the same as a true hi-def production video monitor).
    I am still working with a lot of SD footage.  It seems like anytime there is significant camera movement in an SD clip, there will be tearing somewhere across the middle of the image.  This is true in my source monitor, my program monitor and my second full-screen monitor.  The location of the tearing can vary with each playback.   If I look at the same clip with the VLC player, I don't see the tearing.  Is there something I can do in Premiere to stop this from happening?
    J. D.

    DVI/HDMI Monitoring is a smart solution and has a lot of benefits (e.G. GPU processed video can send directy out to the monitor) but also has drawbacks becaus sometimes you are at risk of occasionally stuttering (SDI framebuffer cards are more stable at this currently) and you have to set the screen refresh rate for yourself (50Hz, 59,976Hz, 60Hz, 48Hz...)
    --> Video tearing is a thing that should not occour on a modern computer with a GTX 460.
    Do you also have video tearing with VLC media player or Windows Media Player?
    --> You have to check you Video driver settings to get rid of the tearing I think...
    I don't have any video tearing with my Nvidia Cards exept one really old 8400GS in a server...

  • My Late 09 Macbook has a loose video cable. Will Apple fix it for free?

    The screen randomly freezes up unless I push the screen slightly forwards or backwards. I'm assuming that this is due to a loose video cable. Will Apple fix it for free? I've tried disassembling it but I can't seem to locate the right screwdriver for some of the screws.

    And even if it was in warranty, disassmbling it may have voided it.

  • Video tearing

    Lately I've been noticing quite a bit of video tearing on my 3g iphone. It looks like the kind of video tearing one sees when connecting a computer to a tv. I don't know how else to explain it.

    Can you describe this a little better? I have a Mac Mini connected to a tv and video plays fine.

  • Fix for video tearing ATI Radeon HD 4200 using Catalyst Driver??

    Hey guys, as the title asks, is there a fix for pretty serious video tearing that I am experiencing on my ATI Radeon HD 4200 video card? I'm using the proprietary driver (catalyst, built from AUR) and would prefer to use that one or, if need be, radeonhd driver as I need HDMI sound output.
    Below is my xorg.conf.

    Select the iTunes library on your computer from the Sources menu in Apple TV and then you can stream. If streaming is not smooth and your router has a multicast setting, try increasing the multicast bit rate. To return to the synced content on your Apple TV, select the Apple TV logo at the top of the Sources menu.
