I did not find this in any searches that I did, but it may already be answered and someone can point me there. I have a 5D3 running ML on 1.2.3 firmware. I would like to record to a video capture card, without actually recording to the CF card in the camera. Recording in H.264 to the CF card stops at 29:59 (I am aware of the limitation). Is there a way to do this? Essentially, open the shutter and have it output continuously until my battery dies? I appreciate any help here that will get me beyond the 30 minute limit, without going to a larger CF card AND recording raw (not an option).
