Some codecs will reduce the file size a lot, others can increase it massively. I'm not up on the exports options in Filmora but if you check your cameras codec and export to the same one, and keep general settings the same (1920x1080p etc), you'll probably be fine.
thanks! not noticing a loss of quality but i'll check the codecs. so many little things to learn
