Ok, I figured it out...
But now, my SD card isn't working.
I tried shooting at 720 and it started but it was missing a bunch of frames so I wanted to cancel it. I did so by flipping the video switch to camera on my 5d3. Then I took my sd and put it in my laptop and it didn't read it. Placed it back into the camera and the camera read it so I did a format on my camera. Put it back into my laptop and it still isn't reading it. Restarted the computer and did a format of the card(in camera) still nothing. Any ideas?
