I have a video to shoot in a few days and I need the best quality possible. In the movie settings the 200 Mbps Option is dimmed on every possible combination of frame rate and image size. I also tried 150MB/sec cards and a 300Mb/sec card. Neither unlocks the mysterious 200 Mbps option. What am I missing?!?!? UPDATE: Problem solved: in movie settings set the HDMI OUT to HD and the memory card to 4K then the 200 Mbps option is available.
