Hi Carrie, you could easily use a HDMI to SDI converter. Black magic makes a very small one that I used on my first rig. Also I believe the C100 (~3lbs) is light enough for the Pilot, as long as don’t add too many accessories. Arms like the Pilot really like to be on the heavier side of their range. I would usually add weight to the camera until I got fairly close. I don’t recommend going over the weight limit though, because there are parts that can fail if pushed too far. Hope this helps. http://Blackmagic Design Micro Converter HDMI to SDI (with Power Supply) BMD-CONVCMIC/HS/WPSU https://www.amazon.com/dp/B01EIOP0QC/ref=cm_sw_r_cp_api_glt_fabc_2PJ0TK9DSBTCRKPDDK9N
