So I currently own a Panasonic hmc-150 and backup video to an external dvd recorder in live time to hand the client a dvd right after the shoot. Though for an upcoming shoot, I would like to use a Panasonic GH5s, which records, even at its lowest 1080p settings, much bigger files than the much older Panasonic hmc-150, I would guestimate at about 3-4 times bigger files when both cameras are set in their lowest bit rate/resolution settings.
My question is, will I be using more dvd's if I use the GH5s? Or does the external dvd recorder (Sony DVDirect VRD-MC5 DVD Recorder) downconvert any signal coming from a camera at a uniform size? I would prefer using the GH5s, but I don't want to use more dvd's in order to do so.
