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 Manager”
- Select “Resource Monitor” on the tab at the bottom and choose the Memory tab.
- Click on the “Working Set” column to see the amount of Physical Memory in use by the processes.
- Start Shotcut and start the export, then monitor how much memory it uses.
