MEP Plus 2014 - MP4 export "Cancelled due to an unknown error"

MarcE wrote on 9/15/2013, 10:42 AM

Just built a new PC and freshly installed a new copy of MEP 2014 Plus. Whenever I try to export a movie as MP4 using GPU acceleration I get a dialog telling me that the export was "Cancelled due to an unknown error".

OS: Windows 8

CPU: i7-4770 / RAM 16GB

Motherboard - Asus z87i Pro (z87 chipset)

GPU: NVidia 760 / drivers 326.8

I read about problems with this in MEP 2013 but it always used to work for me with that on my old system (Windows 7 / i7-930 / GTX 580).

Is there anything I can do to provide debug logs? Are there any known workarounds, apart from disabling GPU acceleration? 

The motherboard does have an integrated GPU on it, which is disabled in windows. I wonder if that's causing a compatability problem?

Hi

When you say GPU acceleration, are you referring to the reference in the program settings and export dialogue that refer to GPU acceleration of transitions and video effects? These are different to selecting Cuda or Quicksync hardware rendering and experience has shown that they can conflict with the CUDA rendering at export. On my machine with MEP2013, if these are selected then CUDA rendering is slowed from optimum.

Try with all references to acceleration disabled in the program, other than the tick next to Cuda or quick sync in the Export > advanced encoder settings section.

Did you use an unmodified MPEG4 Export template?

Might be worth swopping the GTX580 into your new machine and see if anything different happens, also.

Hi

. . . . The motherboard does have an integrated GPU on it, which is disabled in windows . . . .

It will be - as soon as you plug in another graphics card the onboard is disabled.

If you are willing to experiment, pull the NVidia card and test using the integrated HD4600 graphics and OpenCL / Quicksync.

I have a similar spec machine to yours and have found no advantage using CUDA on a seperate graphics card compared to the HD4600 with which I am achieving an average render speed of 43 fps for mp4 export if mixed video and still images,  rising to 53 fps (mts files to AVCHD or mp4 export).

Interesting that you tried dumping the second monitor - I found dual monitor working with a NVidia card to be a bit of a pain with MEP - the HD4600 works perfectly with dual monitor - this is the second reason I dumped th NVidia card.

Thanks for the suggestions

@John - I have the 760 for other reasons - I do a bit of gaming on the box as well, it's not just a dedicated video station. FWIW dual monitors (DVI) have always worked flawlessly for me with NVidia cards, but I don't use any of the monitor / display management tools because they're usually more hassle than they're worth. 

@SceneStealer - I just went through all the options and disabled everything I could find that looked related to GPU Acceleration, then did an export with hardware acceleration ticked in the advanced settings. Same situation, just the error dialog.

And yes, I did use an unmodified export template. It doesn't matter which template I use, they all fail in the same way. 

When I get some time to try messing with the innards of the box I'll try both pulling the GPU and swapping it for the old 580, to see what that does.

I could also try reinstalling MEP 2013, which I know used to work.

The only other difference between the setups - and this is something I can't do anything about - is Windows 8 vs Windows 7. I'll try a lot for the sake of getting it working, but flattening the machine isn't an option.

So after doing some more digging I land up on the tech specs page for the MainConcept video encoder Magix use and see this little gem in the small print

"Boards with Kepler architecture are not supported."

Huh. That means any NVidia card for the past 2 years. If that's not an out of date spec sheet then it kind of sucks - looks like I need to either find different software or swap to a Radeon :-(
