Cubase freezes when exporting "video"

Hello everyone :slight_smile:

I’ve had a very weird issue for about 2 weeks now. When I try exporting a project by going to “File” → “Export” → “Video…”, my Cubase istantly freezes and nothing happens so I have to restart the software. This happens litteraly every time I try it, do you have any ideas why this could be happening ? Until now I’ve never had an issue exporting in video format so I don’t understand why this did suddenly occure.

Thx in advance !

Generate a DMP file and share it via Dropbox or similar service, please.

Once Cubase becomes frozen, open the Task Manager, right-click to Cubase and click to Generate DMP file.

If this doesn’t work, use Microsoft ProcDump utility to generate a DMP file, please.

  1. Please download ProcDump64 from Microsoft (~650kB) and extract the archive to a local folder on your harddisk.

  2. Run Command Prompt (cmd) as administrator (right click and select “run as administrator”)

  3. Navigate (in the Command Prompt) to the folder with the extracted procdump file.
    For example:
    cd C:\ Users \ \ Downloads \ Procdump
    Note: the dmp file will be written into that folder.

  4. Launch Cubase/Nuendo. You can work as usual. At any time, change to the command prompt and start procdump, to monitor Cubase/Nuendo for unexpected behavior (see next step).

  5. Launch procdump64 via Command Prompt:
    Cubase 11:
    procdump64 -e -h -t Cubase11

Nuendo 11:
procdump64 -e -h -t Nuendo10

The -h option will write a dmp file in case of an application hang. This might kick in too early sometimes, in case some action takes a little longer. Feel free to skip the “-h” option, if you are only up for fetching crashes.
The option -e will catch exeptions and the option -t terminations of the application.

  1. Prodump is now monitoring the Cubase/Nuendo process and will write a crash log, in case Cubase/Nuendo crashes or hangs. Perform the action that causes Cubase/Nuendo to crash and send us the generated crash dmp.

ZIP and share the DMP file via Dropbox or similar service, please.

Hi Martin !!

Thx for you answer, as I was reading through your message I had cubase freezed after starting “export video” in the background and when I went back to Cubase, the window opened ! So I tried again, and the issue seems to be, that for a reason I ignore it suddenly takes around 4-5 minutes to open this window, very strange

Do you have any ideas why this could be the case ?

Thank you Martin


Sorry, I have no idea. But it sounds familiar to me. I think I have read something similar here on the forum already. Please, try to search for it.

Hello Martin !

I made a DMP file for you, in hope that it will help you understanding my issue !

I launched Cubase and directly after that, tried “export video” and as usual it freezed and I did the DMP file.

Thx !!


I have never seen DMP like this. It seems like a problem with font type character. There is something like UTF8 is invalid…

What language do you use in Cubase, please? What is your system language, please?

Hi Martin !

My language in cubase is english, and my system language (I think you mean of my computer system ?) it’s french !
