1dx Mark II 4K corrupted footage In: FOOTAGE Posted October 18, 2017 I just got a brand new 1dx Mark II, I’m using a SanDisk cf card, not a cfast card. I recorded a lot of 4K footage, and about half of it came back corrupted - I could view it in the camera, but not on the computer. Anyone have any ideas on how to fix this? Can I get the footage repaired? I can’t find anyone else who has had this problem so far.
