View Full Version : Stuttering problem resolved

05-10-2004, 12:19 PM
Recently we had been having a severe problem with video clips of all sorts stuttering where they had not before. We originally just assumed it was the newest T[3] patch, which provided higher quality processing.

However, we happened to be browsing the forums for another video editing company and noticed that a specific service patch for XP (namely KB824141) had caused tremendous trouble to the software because the patch changed a low level paint method, which was killing the screen redraw rate. Uninstalling the patch was the original cure.

We tried uninstalling that patch on our T[3] machine and remarkably enough the Toaster is back to its happy self. All the recent stuttering we had been having are gone. If you've been having stuttering video clips lately, check to see if that patch is installed. If so, uninstalling it might help your system.

Unlike others, I haven't had stuttering problems, but that's a valuable little tidbit, thanks Joel.

I have that patch and I would guess most here with XP do. It was installed as part of the Automatic Updates. There were some security issues addressed in this MS patch (buffer over-run exploitations).

It would be best to confirm this has caused VT3 slower performance before we start recommending removing it. On the other hand, it would be great to find out this is the cause of the onset of studdering problems for some (including me).

I will ask Andrew to have a look at this.

Maybe something else.

We are currently testing this. I can tell you that it made AVID Xpress Pro completely unusable......, so I would consider it as a cause for sure.

So far, this seems to be helping in most cases.

It may help, but I can say that I have the "stutters" and our system has NO Windows updates/hotfixes, etc.

none at all? because you should have the critical updates, except the problem one.

How would I know if I have the patch. In my
Add/Remove Programs I dont see it.
So if its not there then where do I look?

>>How would I know if I have the patch.

Run Windows Update as usual.

When it gives you the choices of updates in the left window, click 'View Installation History' under Other Options.

Not sure how to remove if it's not in Add/Remove tho.

How would I know if I have the patch.
If you go into Start menu/control panel/add remove programs you will see a list of windows "hotfixes" that are installed on your system.
Look for one that says KB824141 and select remove.

The computer shows no updates installed. I have NEVER connected the computer to the internet so it would have now way of getting them nor would I think they would be needed (at least if everything is working, don't mess with it!)

Here is a test with you guys that have very fast machines
and drives can try.
(My quality is medium)
1) Place a clip in the timeline thats at least 20 second long
2) Offset the position a little up. Turn overlay on.
3) Place the noise effect under it.
4) Place a another clip in the timeline
thats at least 20 second long under that. Turn on overlay.
Position it down a bit so you can see the other clip.
5) Place a blur effect under that.
6) Now place an audio clip under that.

hit play. Wait 5 or 10 seconds. If you hear the audio stutter and
your light is greeen. Let us know.
I have changed my settings all sorts of ways and this causes
stutter. (My quality is medium)
