Have you ever tried to slow down footage only to see your result is choppy or not what you were hoping for? Thankfully in Final Cut Pro X there’s a new feature called Optical Flow that gets rid of that problem.
How does Optical Flow work?
First let’s go over how exactly this neat feature works. Instead of duplicating frames or blending them together, Optical Flow creates new frames in between the current ones. This gives an extremely better-looking result!
How can I apply Optical Flow?
It is very easy to use the Optical Flow option in Final Cut X. First, select the desired clip. Now, click on the re-time icon (as seen in the picture on the right). A drop-down menu will appear giving you various options including slowing it down and speeding it up.
You will now notice a colored bar appear above your clip in the timeline. Depending on your re-timing selection it will be orange (slowed down), green (normal speed), or blue (sped up). If you were to play back the clip, it may look like what Final Cut 7 would produce. Fear not! Go back to the re-time icon and go to video quality followed by Optical Flow. Now comes the fun part: waiting! It might take a bit, but your Mac is hard at work analyzing and producing stunning results.
If you don’t like FCPX’s three timing options, just click and drag the colored bar at the top of the clip. You will now notice the percentage of the re-timed clip go up or down.
