Neat project though you might want to consider hiding the old UI in the flash game and binding things to hotkeys so you can play through the animations as you record them. Of course this will require some knowledge of actionscript and using a flash decompiler like jpexs flash decompiler.
I actually considered doing this idea with Zone's Midna game as it's my personal favorite but unfortunately I'm too nit picky about things and considered doing stuff like moving the animations over to spine, flash to unity animation porters(didn't really have any luck with that), and lots of other goofy stuff. Kudos for finishing something I couldn't and keeping it simple.
