I’ve talked before about slow motion with Final Cut Pro X and optical flow. Here is another example, this time shot on the 5D Mark II which maxes out at 30fps. The footage was slowed to 10% using FCPX retiming feature and optical flow. This example is by UK-based photographer Timothy Cochrane. I contacted Tim and he informed me that this was shot at 25fps 1/60 shutter at about 400 iso and f4.
