When I try to export an edited video to mp4 and save, my pc uses 100% CPU and blue screen crashes… I do not know what to do and it is very aggravating.
That is not the fault of Shotcut. It is more likely a problem with a driver or your hardware such as bad RAM. If you need to turn down the CPU usage in the Export panel turn off parallel processing in the Video tab, and set the number of threads in the Codec tab.
