LD_LIBRARY_PATH=Shotcut/Shotcut.app/lib Shotcut/Shotcut.app/qmelt …

profile is spelled wrong, and the .mlt XML file already includes profile information.
there is nothing else done by the export xml writer.
The export XML writer adds a
<consumer> element that contains the export settings. You can alternatively supply a
-consumer command line option, but that will take some time to teach you. Rather, you can right-click an export job and view the XML it generated, and save that to a file to run with melt or qmelt. qmelt is simply a wrapper to melt that initializes Qt on the main thread, where it prefers. This is needed on some platforms when using WebVfx (HTML filters) and/or Movit (GPU processing).
