Is there a rough estimate of the memory required to export an file with roughly an hour of 1 mp4 and 1 mp3?

See my response earlier this eveing to another Memory query:

You are runing low on avaliable memory

How much memory Shotcut/ Melt uses depends on lots of things. How many filters are you using? How complicated are these filters? How much keyframing are you using? How many transitions? How many tracks? How many clips? What resolution are you exporting to? What resolution are your clips? What codec are you using? are you using “parallel threads”? Are you using “Hardware Encoding”? … The only way to know is to try it and see. On your windows system: Reboot Use Ctrl Alt Del and choose “Task M…

How to Reduce Memory Usage

Here are ways to reduce the memory usage in general: Save and restart Shotcut Close other browser tabs. Close other applications. Reboot (does all of the above). Here are ways to reduce the memory usage of your project: Reduce the resolution of the Video Mode. Reduce the number of tracks. The number of tracks will increase the amount of caching to prevent files from being closed and reopened repeatedly from one frame to the next. Here are some ways to reduce the memory usage while editing: …

HELP : Export failed with exit code 3

Another thing to do (mentioned by me elsewhere) on tight memory issues is to encode outside Shotcut: in Shotcut, start an export job and stop it right-click the job and view XML save XML with .mlt or .xml extension (It now includes a <consumer> element that contains the export parameters including file name.) close Shotcut open a command line window run like /path/to/qmelt /path/to/xml from step 3 (how this is done exactly depends on OS)
