Program not responding when export 4k prores 4444 on Win11

[ootonn]

Hello, I use mlvapp 1.13 or 1.12 on Windows 11 to export 4K prores4444. The program will not respond for a period of time. Especially when dealing with long MLV,

More information needed: what are the settings, both - used in camera+type, in MLVApp receipt and export? Is any other export working?

[ootonn]

Thank you for your reply.

Camera:

• EOS M + 5K FRTP ;

Settings:

• RAW Correction:

• Debayer Algorithm:

• Details:

• Transformation:

• Profile Preset: Alexa LogC ;

• Resize: 3840*2160;

• Codec: Apple ProRes 4444 & ffmpeg Kostya

• Other settings are the default

And if I use cinema DNG, I can successfully output all of MLV.

cDNG is not processed... so that's a don't care in terms of the problem. Could you do a screenshot of your used export settings please? Is the 32bit version working? "program will not respond for a period of time" means it crashes, or you just have to wait until ready?

[ootonn]

Sorry to keep you waiting. 32-bit programs usually run longer, but eventually crash. I used mlvapp to export 50 videos all night, and only 5 videos were exported in the end. So I think the program has crashed. This is my screenshot.

Then tonight, I successfully exported all videos(ProRes RAW 4444) using the software generated by QT 5.14.2 64 bit debugger. And I noticed that there is an additional "daniel_fort ml focus pixels-2020-06-28. zip" file in the debugger folder.

Did you close the command window? This will stop ffmpeg file output, while MLVApp processes.

Did you build MLVApp yourself with Qt 5.14 now? The old focus pixel file is part of the repos.

[ootonn]

I didn't close the command window. Yes, I build MLVApp now.

In the process of using the Qt debugger, I found an error.

[masc4ii]

What is the error? Line of code?

[masc4ii]

If you mean the application output: this nvshext.dll thing is a NVIDIA graphics card driver error (google tells - I've never seen such output in QtCreator on any system). Whyever this error comes up - MLVApp doesn't use any GPU. So could be a problem with your specific system and/or its drivers.

[ootonn]

Sorry, I'm busy with my studies these days. I haven't found any other errors except program output errors. I'll export the material to see if I can find any errors.

Solution for Win11 users from Arto Holopainen: If you have export crash issues, run MLV App (I'm using 64 dynamic ver) in Win8 compatibility mode. No more crashing.

Maybe this also works for this issue.
