when I was using a nano flash,you could record without “media” in the camera.. but only by activating record at the nano flash .. I bought a remote cable eventually.. as a real pain when mounted on the handle when hand held..
Although TC rec activation with media in camera was much easier.. and gave a back up too..
I wouldn’t use HDMI if I were you.. totally crap .. always breaking.. BNC SDI out is better if that camera has it..
But I wonder for your purposes .. why not just go with the internal recording to SxS cards.. ? a very tried and proven system of recording.. ??
Thanks for your response,I tried ex too.. I must be doing something wrong then.. I have the explorer and preview windows open..download clips to a folder on desktop.. that folder opens with all the clips.. then I select all and go to the export pull down list.. I want to make all the clips into one movie file.. I guess I have to have some other editing software to make one movie file out of all the clips..
