Final Cut Pro X has a pretty cool feature called Optical Flow that allows you to create Slow Motion Video without having to install any additional plugins or purchase software. We shot the Diet Coke/Mentos video below on a Canon EOS Rebel T4i at 60 frames per second with a shutter speed of 125th.
Yeah, yeah, I know… anti-climatic is an understatement for the “explosion” we were going for. Keep in mind that this was our fifth attempt and I’m not about wasting poisonous consumables. In any case, you get a nice idea how much of the video is retained even when slowing the footage down with FCPX Optical Flow.
Here’s a little insight on how we did it: After dragging the clip into FCPX, I selected the portion that I wanted to be in slow motion then highlighted it. Next, I clicked on the retime drop down tab and selected one of the slow presets. I then clicked the retime icon again, chose video quality and selected Optical Flow. The video must then render out and that’s it. Super simple and the slow motion looks fairly good considering it comes natively with FCPX. Any thoughts?
