Right now, .fcpxml is the only .xml format that either our Sumo 19 and Shogun 7 can generate, but there are two workarounds to convert the .fcpxml file that contains all of your switching and transition data to something that Adobe Premiere can work with.
1. Get the paid macOS software "XtoCC" which allows you to conveniently convert the .fcpxml to an alternative .xml file that Premiere can recognize.
2. Download the free version of Davinci Resolve and open the .fcpxml file in there. Once loaded and verified that everything on your timeline gets displayed correctly, you can go ahead and export your project as a Premiere .xml. After the export is completed just right click on the file that you’ve just created and choose to open it in Premiere.
