YouTube video plays in the left upper corner of the screen.

Very well. The problem is that since the update for Firefox 37.0.2 I have problems playing video on and sometimes In Youtube I play a lot of videos show only now in the upper left corner of the screen and the size of this video does not change even in full screen. There's the size of a small tile. I tried to disable add ons, and virtually everything suggested on various web sites. On new grounds, videos and games returned backwards and forth like the occasional video, but the video question on Newgrounds is not as bad as the issue that Firefox has with some of the games.

I tried the games on Internet Exploder and exact same videos and I get these questions. It started to happen after the update to 37.0.2.

I use Windows 8 (COMPLETELY up to DATE) and I have the latest version of Flash. I managed to narrow it down to a problem of Firefox and many others still reported in various sites addressing this issue as a bug in Firefox. I agree with this observation. Even my video drivers are also updated. My computer uses the Intel 4600 drivers.

Features model relating to this issue:
ASrock Z97 Pro3
Intel graphics (onboard)
16 GB of RAM

If a right click on the drive on YouTube shows a pale menu mentioning the HTML5 player, which uses built-in features of Firefox. If she mentions the Flash drive, then it uses the Flash plugin. It would be useful to know the next steps.

It is a standard orientation which addresses the most common issues with the Flash Player plugin. I'm sure you've seen some of it before, but just in case:

(1) If you have any recorders/downloaders who interact with Flash media to ensure that they are as up-to-date as possible, or disable them temporarily.

(2) turn off hardware acceleration in Firefox and Flash

(A) in Firefox, uncheck the box here:

"3-bar" menu button (or tools) > Options > advanced > General > "use hardware acceleration when available.

Which takes effect the next time you exit and restart Firefox.

(B) in Flash, right-click in the press and choose settings, then the first mini tab and uncheck the box to use hardware acceleration. More information in this article from Adobe technical support:

(3) turn off mode protected (Windows Vista and later)

The functionality of the safe_mode of the Flash player plugin has security benefits, but there seem to be some compatibility issues on some systems. There is a hidden for this parameter:

(A) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

(B) in the search above the list box, type or paste the flash and make a pause so that the list is filtered

(C) double-click the preference dom.ipc.plugins.flash.disable - protected mode to change its value from false to true.

It cannot take effect until all the Flash was discharged for a few minutes, or you close Firefox.

  • Whenever I play youtube videos, they shake from left to right and to go at different speeds.

    I have windows 7. A couple of days, I went to play youtube videos and they all shake from left to right and go at different speeds (very erratic). This ONLY happens with videos from youtube (HTML5). When I play other videos(non-HTML5), they play very well. Also, the sound on youtube videos are fine, only they do not match the mouth (s) of people talking. The mouth move faster. I've checked all my plug-ins and everything is up-to-date. My firefox browser is also the last version. I did a malwarebytes scan and it came up with nothing. All the settings on the youtube videos are also where they should be. It happened for about 5 days. Can someone help me?

    Thanks Guigs. I followed your instructions and found out it was a 'acceleration hardware problem' that was the origin of the problem. I unchecked the box and YouTube videos play very well! Thank you for taking the time to help me.

    Thanks for the follow-up.

    Missing in this equation are the Premiere Elements version you were using and the operating system on which it is running. But...

    The Act is accomplished. But... Up to now, and after that you went ahead and moved to version 12, we now learn what Premiere Elements version you were using. We don't yet know the operating system involved.

    You said first Elements 10. First 10 Elements is affected by a problem serious display known if the computer uses an NVIDIA GeForce video/graphics card card. In this issue, the only cure is to roll back the version of the driver about may 2013. The description of the problem and how to make the rear roller are described in one of the messages at the top of this forum. What video/graphics card your computer use?

    On another front, Adobe will release a new version of Premiere Elements any day now. Not one, but Adobe knows the function defined for the new version. This type of information is announced at the time of the release of the new version.

    So the solution to the problem you presented in this thread could have been...

    1 roll back the version of the NVIDIA GeForce driver for all may 2013 if possible (Windows 8 or 8.1 64 bit, maybe not possible)

    2. move to a different version of Premiere Elements (which you did)

    I offer the foregoing for consideration so that you can review your decisions. We are pleased to learn that the first items 12/12.1 works for you.

    Please do not hesitate to ask questions and seek clarification, but do not forget that the answers are in the details.

  • video covers all the screen


    I downloaded a video clip (MP4 360 p) from Youtube

    When I change in pre 10, her height is OK, but the width is too small and so left and right there are black vertical bands. Magnification is set to 'Fit '. If I put a magnification of 75% or 100%, then the video covers the entire screen, but at the expense of resolution.

    is there a way to stretch the screen width while leaving the height the same?

    What is your setting of PrE 10 project?

    What are pixels x dimensions in pixels of this video from YouTube? If you do not know, you should be able to find that in pre with Rt-click > properties in the project Panel, or you can run this video through G-Spot, or MediaInfo (both free of the folder info utility).

    The black stripes are a sign of a mismatch between your Source of the layer (the YouTube video) footage, and the setting of the project frame size.

    Good luck


  • Are preferably looking to keep the focus of the timeline in place after the playhead to play off the screen

    Hi all
    I think I used to have this setting put in place in a previous version of PP, but I can't remember where it was. I would like to be able to keep the focus of the timeline in place and leave the playhead to play off the screen. At the moment if I'm working on a section of the timeline, as he plays and the playhead leaves the window it will pop the update so that the playback head is located near the left side of the window and away from the section, I was working on.

    Is there a setting to turn this off? I really prefer monitor me my position of the window. Thank you!

  • videos and images are turning to the left upper corner of the screen

    can someone tell me how to solve the problem?   Videos and commercial images flashing in the upper left corner of my screen to the place where they are supposed to be.  But the controls for videos, play/pause, volume, etc. are in the empty box where the video is meant to be.


    Check the following if you use IE9.

    Open windows control panel, open Internet Options and click the Advanced tab.  Under the graphic acceleration, make sure you there is not a tick against 'use made instead of GPU Rendering software.  If it is, uncheck the box and click on apply to save the change.  Restart IE.

    If the above doesn't help (or does not), download the latest installer of Flash Player and save it to your desktop.  Then, close all browsers, open windows control panel, open programs and features and uninstall Flash Player, if it is displayed here.  Once completed, restart the PC.  Now, double-click on the Setup program on your desktop to reinstall Flash Player.

    Another option is to download and install Firefox as a temporary measure, as the latest version of Adobe Flash seems to work OK with that - you may need to run the installer of Flash again after installing Firefox.

  • Videos YouTube are pushed off the screen to the right by an ad, how to fix?

    When I click on a link to a youtube video, the video appears for a few seconds in the correct location of the site, but then an ad square appears on the side left forcing the video screen to be pushed all the way to the right and off the screen. The video will be displayed on the right side of the column of the videos ' read popular. " Sometimes, a scroll bar appears at the bottom of the window, because the page is now much broader, which will allow me to scroll right to see the video, however, sometimes the scroll bar does not appear and I see only the left edge of the video.

    I reinstalled Adobe® Flash® Player, which did not help and I also have the latest version of Firefox. This began to happen quite recently... maybe a week, there is or not.

    The reset Firefox feature can solve a lot of problems in restaurant Firefox to its factory default condition while saving your vital information.
    Note: This will make you lose all the Extensions, open Web sites and preferences.

    To reset Firefox, perform the following steps:

    1. Go to Firefox > help > troubleshooting information.
    2. Click on the button 'Reset Firefox'.
    3. Firefox will close and reset. After Firefox is finished, it will display a window with the imported information. Click Finish.
    4. Firefox opens with all the default settings applied.

  • No youtube videos play in Firefox, but I can play them using Safari and I have made no change in my system.

    On November 29, 2012, I could no longer play youtube videos in Firefox. They play well in Safari. I have made no change in my system, Flash is up to date (and has been; this has not changed), and RealPlayer is not active. What can I do to fix this? One minute, he was working; the other, it wasn't.

    I have only one computer.

    I have reset Firefox instead of making the diagnosis, which seems to have solved this problem, but now I have more Ad Block Plus. I can't wait to see what I have to do to get Firefox the way it worked before.

    Thank you.

  • Not all YouTube videos playing

    When I access my Youtube playlist videos, I can't see all of the videos through my DVD player that I can on my computer. What are the rules that determine what I can see using the YouTube videos DVD player?

  • Downloaded videos play only the sounds

    My son works on a project and makes a few digital video on a SD card.  Downloaded to his laptop and mine (Vista) and it is in the .mov format.  It will be important on his computer and mine with the sound, but no video is there.  Uploaded to photobucket and we can see the video and hear the sound.  We tried opening both Windows movie maker and Windows media player?

    The .mov file format is a video format MPEG 4, released in 1998 and is used in Apple's Quicktime program, which is similar to Windows Media Player Media Player. As WMV (Windows Media Video) format .mov is connected with Quicktime

    Google for a free video converter and convert your .mov file formats supported by Windows Media Player.
    Here is the link to show you what formats are accepted by WMP:

    Suggestion only: always choose the wmv format, most foolproof format.


  • No message signal to s-video input on the screen - how to remove it?

    I pressed a button on my monitor by mistake, and now I have a blue box with the message "no s-video input signal" on the screen at all times.  It's annoying because it's in the upper right corner, covering the buttons I use to close, reduce and optimize windows.

    I tried right click but nothing happens.  How can I get rid of this error message?

    Hi AnneHotmail,

    1 What is the message appear after you restart the computer?

    2 are you able to show display on monitor other than the blue message box?

    3 is this a laptop or desktop?

    I suggest that you restart the computer and check if it works.

    If restarting does not solve the problem, then check and ensure that the monitor is connected correctly to the computer.

    Also try the method below and check if it works.

    (a) turning the computer off.

    (b) disconnect all cables from their bottom or the sides of the monitor (particularly the power cord). Unplug the power supply cord releases all their reset circuit locks

    (c) press and hold the power monitor for 5 seconds button

    (d) plug the monitor power cord

    (e) turn on your computer and check if it helps.

    If the previous step fails, then you will need to consult the manual of the monitor to restore its default settings or contact the supplier of the monitor.
