HEVC causing Magix to crash when exporting - ucrtbase.dll error

BrenyC wrote on 9/5/2025, 5:23 AM

My Movie Studio 2024 program has been working fine since I installed it. nothing has changed, no new programs or updates and then started crashing. First disc I burnt to worked fine, did another shortly after and crashing part way through encoding.

I have worked out it is not necessarily a Magix problem as it also did the same thing on another version. I have understood it is HEVC, as when I export as HEVC I get the same result. I import files into Magix, export and one will crash, sometimes I export the same ones in after restarting and works fine. If I export via any other format there is no issues.

I have searched online finding it could be Microsoft Visual C++redistributable, so I uninstalled those and reinstalled from Microsoft. - I reinstalled the HEVC file - I made sure windows was updated - I have tried using different drives - I have uninstalled and reinstalled Movie Studio 2024 and still the same issue - in every crash when I restart this is no crash log to display, reporting to Magix also shows no text. Any ideas would be much appreciated. Thanks.

As you have discovered, urctbase.dll is a core Windows file.

Searching for suggestions for how to correct the problem led to various web pages offering possible solutions but most seem to suggest that running system file checker is a good place to start. If you're not sure how to do this this Windows page gives full details.

Hi

. . . .  'UCRTBASE.DLL error'  . . . .

This could be a display driver issue, last time we saw this issue it was with an Intel integrated GPU, are the graphics drivers for the Intel UHD 770, and, if you have a discrete graphics card, eg Nvidia, AMD or Intel also installed, which model is it and are its drivers also up to date?

Note: If you have a Nvidia GPU you should be using the Game Ready Drivers, Magix recommend these in preference to the Studio drivers.

Hi John, once again you, along with others, have managed to get to the bottom of something for me regarding Magix!

I do have Intel UHD 770 and Nvidia GeForce RTX 4070. I updated Nvidia as suggested and no change, I then went to Intel's site, got it to detect the processor and there was an update and I think it has fixed the issue. Before there would be about 1 in every 15 files tested would throw up the error, I just went through about 100 files and no error. I will test more extensively with trying to burn another bluray tomorrow, that was faulting every time.

Hope this will help other in the future. Just strange how suddenly it decided not to play nice.

Brendan.
