I agree with @Hudson555x. You are more than likely running out of memory. Not only is a single process (running .exe) limited to 3 GB RAM on 32-bit, which is very limiting for video editing, your entire system only has 3 GB RAM! Export in Shotcut runs in a background process. This means when export starts the operating system itself is taking some RAM, Shotcut UI is taking a fair amount of RAM to load itself plus your project, then the background export process (qmelt.exe) needs to load the same project and spend RAM. Ways to reduce RAM usage:
- Reboot
- Close all other applications
- Limit your project (Video Mode) resolution
- Export outside of Shotcut:
- start an export
- stop it
- right click export Job and view its XML
- save the XML
- close Shotcut
- run cmd.exe
- cd C:\Program Files (x86)\Shotcut
- qmelt \path\to\save\xml
