Posted on by Optical flow, and it’s less sophisticated cousin, Frame Blending, are techniques that Final Cut Pro X uses to smooth playback of extremely slow-motion clips. The problem with slow-motion created using software (as opposed to that shot by the camera) is that the slower the video plays back, the more jerky the images appear. This is caused by not having enough frames to smooth out the movement.

For normal or fast video, this isn’t a problem. But for clips running at 20% of normal speed, or less, it’s a big problem. This week’s online training () shows how to create speed changes in Final Cut Pro X. The video below is an excerpt from this webinar and illustrates what optical flow is, when to use it, and how to apply it. Advanced Level Pure Mathematics Pdf there.

Final Cut Pro has never been good at slow motion. The introduction of FCPX has now brought Optical Flow retiming within the app -so what does video at 1% of original.

NOTE: Be sure to view the video at full screen so you can see the subtle changes that frame blending and optical flow add to the playback.

I would very much disagree with the fact “optical flow was designed for speeds below 15%”. In most cases, even in the example you show here, it degrade the picture quality enormously making is close to useless. I’d rather say it’s completely up to the shot when this should be used and how good it works but I rarely recommend a client to push slow-motion further down than 50% in post. In extremely good cases perhaps 25% – and even then a lot of shots start to enter the “time warp effect” when using optical flow. It’s all about the shot and what works and not, you can’t really put a number to it and mostly retiming in post gives odd side-effects. Larry a lot many of us are facing a problem in understanding the basic concept of fcpx.everything has to be kept in control all the time.clips keep falling apart,snapping and getting disturbed.kindly write a small write up about how one should approach fcpx, how should one just replace concepts to be able to do exactly how they worked earlier.because by changing the interface.same needs of editing won’t change.plz tell us how to think to use this interface.and if you have written something like this.kindly let me know the link.Thanks.
