Flash Video Lag?

Dec 12, 2011 7:52 PM

I've been experienceing a kind of "Lag" in video playback.

After about 10-15 minutes into the video, the video playback starts to lag behind the audio.

The audio plays fine, at it normal speed, while the video will become out of sync and you can notice that the mouth of the people in the video are moving far slower than the audio playback.



System Information


Operating System: Windows 7 Ultimate 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.110622-1506)

Processor: Pentium(R) Dual-Core CPU T4400  @ 2.20GHz (2 CPUs), ~2.2GHz

Memory: 4096MB RAM

DirectX Version: DirectX 11


Display Devices


Card name: Mobile Intel(R) 4 Series Express Chipset Family

Manufacturer: Intel Corporation

Chip type: Mobile Intel(R) 4 Series Express Chipset Family

Display Memory: 1759 MB

Dedicated Memory: 128 MB

Shared Memory: 1631 MB

Current Mode: 1600 x 900 (32 bit) (60Hz)

Driver Version:


The issue (lag) is happening in Firefox 8.0.1 and Chrome 15.0.874.121

(I do not have IE installed so am not aware if the issue exist in that browser)


I have tried all the steps here: tain_Flash_videos

None of those have resloved the issue.


Notes: This issue is occuring on 2 other laptops in home. One running Windows Vista, the other is running Windows 7 same as the laptop from above.

There is a 4th laptop, running Windows 7, which is not experienceing the "Lag" issue: But I believe that is due to Flash 10 being installed instead of Flash 11 like the others.


I will be downgrading the flash version on one of the problem laptop to see if that will resolve the issue.

    Could you provide a link to a video where the problem you described occurs?

    From multiple sites, including YouTube.




    I seem to have resolved the issue...

    Adobe Flash Updated to a x64 but Firefox is not available in x64.

    So I just uninstalled the x64 version of Flash, and manually downloaded/installed the x32 version


    Videos are play all the way through with No lag that I've noticed as of yet. Have checked 5 videos (each about 30min)


    Firefox x64 is currently under development. There's a third party version of Firefox x64 available called Waterfox, download from here:


    However, because it's not an official Mozilla release, it might be prone to bugs. If the 32-bit version of Flash works for you, then I would stick with it if I were you. You know the old saying, "If it works, don't fix it".
