Converting
Once the flash player is installed, you can use it in conjunction with the capture utility in the Windows gaming overlay (Win+G) to record playback of the SWF file. Note that this does not work with all PC graphics hardware.
Contact systems support if you need assistance in converting legacy Flash video content.
