I was searching for how to move Slow Motion video from my iPhone 7 to my Windows PC. All the answers were coming up using iMovie and other Apple software.

As I was not moving the video to a Mac this was not useful. I did find my old friend FFMPEG could make the move quite nicely. Using the command:

ffmpeg -i SlowMotionVideoFromIphone.mov -vf "setpts=4*PTS" SlowMotionVideoOnPC.mp4

does a nice job with the video, but I've not found how to re-sync the audio yet. That's why I am asking if anyone else has tried this and found a solution for both video and audio?

  • I'm not familiar with how to do this, but fwiw, "-vf" stands for "video filter", which is why audio is unaffected. – Wowfunhappy Dec 5 '18 at 16:53
  • Handbrake uses FFMPEG, I wonder if that might provide a better, more understandable user interface? – Steve Chambers Dec 5 '18 at 17:09
