Body: <p>I created a timelapse video from iMovie software and set the time to 0.1 second for every image. But the final output is not satisfying. It seems a bit slow video. I need the clouds to move faster, but they are moving slowly. It is total of 30 second video. I need it to be 15 second video, so that I can get a desired effect. But I cannot change the setting lower then 0.1 second in iMovie. Any suggestions?</p>

  In iMovie you can change the speed of a clip by selecting it in the timeline and then clicking on the icon that looks like a speedometer:
  
  [![enter image description here](https://i.sstatic.net/zKEfJ.png)](https://i.sstatic.net/zKEfJ.png)
  
  Then click on the "Speed:" popup menu and choose "Fast" or "Custom". The "Custom" setting lets you choose how much faster to make it (like 200%, or 50%).

  You can use [ffmpeg](https://evermeet.cx/ffmpeg/), a command line program, to double the video speed:
  
  ```
  ffmpeg -i input.mp4 -vf setpts=0.5*PTS output.mp4
  
  ```
