How do I save a copy of my video at 2x speed on my Mac or iPhone? Not just to view it faster, but to save a copy of it at 2x speed.

Thanks for posting in the Apple Support Communities Supermarette,

The ability to play, or save edits to movies may depend on the software that you're using.

If using QuickTime, the following information may be helpful:

You can vary the playback speed of a video using the forward  or rewind button . To change the playback speed while playing the video, click the forward or rewind button until your video plays at the desired speed. Playback speeds include 2x, 5x, 10x, 30x, and 60x.

You can vary the playback speed in small increments (from 1.1x to 2x) by Option-clicking the forward or rewind button  while the video is playing.

You can also choose a playback speed before you play the video. Click the Share and Playback Speed button , choose Playback Speed, then choose the speed you want.

If you want the file you’re playing to appear in front of all other windows on your screen, choose View > Float on Top so a checkmark appears next to it. Choose it again to turn it off.

Open and play a file in QuickTime Player on Mac

With iMovie, you have a lot more editing flexibility. You can learn how to change the clip speed in iMovie, here: Change clip speed in iMovie on Mac

We hope this helps!

You can't save a video/movie at 2x speed. The movie is the movie. What you can do is play it back at 2x speed and most video players will allow that.
