Sudden onset of Magix MEP lock up when using 3D title templates

Jack-Douglas wrote on 11/28/2020, 6:33 AM

I have a project that I have I've been using the 3D animation basic template as the date for that clip scene. Now suddenly when I use this same template MEP freezes and I have use task manager to close the program. I have completely removed MEP and all the files/folders associated and reinstalled/updated with no resolution of the problem. I have rolled back recent window 10 updates, also to no avail. I have also tried adjusting the MEP video graphics settings to different graphic processors. The problem occurs with all 3D templates.

Hi Jack and welcome to the user to user Movie Edit Pro forum.

Have you checked with Intel and nvidia that your UHD graphics drivers (not game drivers) are up to date?

For Intel that should be 27.20.100.8935

For the nvidia it should be 27.21.14.5206.

Hi

. . . . For the nvidia it should be 27.21.14.5206 . . . .

For the GeForce GTX 1060 the Studio driver is version 457.30 - see here.

The 4 sets of digits are the required standard Microsoft internal reference numbering system for drivers, they indicate (in order)

27 = Windows Display Driver Model 2.7 - can, but not always, also indicate the Windows version.
21 = DirectX rev 21 (12.1)
14 = Base number
5206 = Build number

Intel use these as reference number for their drivers, however Nvidia do not they have their own version numbering system for drivers in the 3.2 digit format, the individual components of the drivers have to have the Microsoft referencing system.

Hi John.

I wasn't aware of that. I have been going by the driver update support.

I have now started installing that driver and for now my desktop display has gone nuts but has not yet fully installed.

Hi Ray

OT however

. . . . the driver update support . . . .

All that really shows is if you have a Windows version compatible driver, if the first 2 sets of digits were any thing else on a Win 10 PC eg 10.10.xx.xxx then I would be very worried as this is a Vista driver and could indicate the drivers have been hacked to get installed.

AFAIK the MS numbering system is specific to drivers only so the installers know if the driver being installed is compatible or not and if it is the current version.

Hi John.

I uninstalled the last driver for the nvidia card and then ran the nvidia installer. It ran to see if it was compatible and then installed with an 'instillation complete' message. Then I restarted windows.

On opening the driver reporting sections in various parts of Windows for verification I still get this.

I'm using Magix Movie Edit Pro Plus Version 20.0.1.73. I have rolled back my NVIDIA driver to an earlier version, but it is a game ready driver. I will try the recommended studio driver. I should also mention that after I close MEP with task manager, I'm left with this error message:

Hi Jack.

It would seem your shut down problem with MEP and the problem with the 3D graphics are related because the X3d.exe is a Xara related problem that controls the animated 3D graphics section. This could mean a corruption of the MEP installation.

Please await the others replies first though as I may be wrong and if I'm correct you may need additional guidance from the others as how to safely do a complete uninstall of MEP without producing more problems.

While closing the unresponsive MEP today, I saw this process running: Bridge32_v103 (32 Bit). It is a Magix associated process, but I wonder if the 32 bit would create a conflict with my 64 bit system. Forgive me if this sounds wrong. My knowledge base is limited.

Very doubtful as a lot of various parts of some applications still run at 32 bit. Web browsing sections for instance are likely to be 32 bit.

Problem solved. Uninstalled all Magix applications, performed PC search for all Magix files, folders, etc. Found some that I did not find on previous reinstall, deleted them, rebooted, and then reinstalled MEP. Now the 3D title templates works perfectly. I saved the project I was working on as a HD video file and now will begin where I left off. Thank all of you for your input and suggestions. Hopefully this will not happen again.
