Part 2:Speed Up a Video on iMovie for Mac [without Changing Pitch]

iMovie for Mac brings even more flexibility to desktop video editing, but iMovie 10 completely rewrote the script when compared to iMovie 9. First, iMovie was written for 64-bit systems, which was a game-changer and in line with Apple's strategy of completely doing away with older 32-bit applications. iMovie 10 also brought in a new library file system, which is very similar to the one in Final Cut Pro X.

With regard to speed control, the whole approach was changed, with the newer version being far more intuitive, especially when changing speed of multiple parts of a video clip. You can see from the following steps how it's become much easier with the newer version.

Speed Up a Video on iMovie iMovie 9 & iMovie 11

Step 1. Import video to iMovie.

Select a video from the Event Library preview area and drag it to the Project Library on the top left. Select the project and hit the 'i' key to bring up the Inspector pane.

Step 2. Find the speed control feature.

Here, click Convert Entire Clip to process the video, then move the slider to the right when you see the speed controls.

Speed Up a Video on iMovie iMovie 10

Changing the speed of a video in iMovie 10 got much simpler, as you'll see.

Step 1. Import video and click Speed icon.

Add a clip to your timeline and simply click the Speed icon.

When you see the speed controls, you can choose one of the presets or choose a percentage.

Step 2. Fine-tune the video speed.

After you do this, you'll see either a rabbit icon or a turtle icon on the video clip, which indicates whether the video has been sped up or slowed down.

You'll also see a slider for that clip, which you can move left or right to fine-tune the speed.

If you don't want the audio track to be sped up as well, select the checkbox that says Preserve Pitch after clicking the speedometer icon in the first step above.

Note: You may have noticed that the pitch has been changed. To preserve the pitch of the original audio, check the Preserve Pitch checkbox.

4Practical Tips You Shouldn't Miss!

1. Speed up part of a video clip with iMovie

If you have a long video, and you just want to speed up a part of it, you can create a range by holding down the R button while selecting the relevant portion in the timeline.

After that, click the speedometer icon and choose Fast from the speed pop-up menu. You can also select Custom to apply different speeds to different ranges. This will keep the speed change of the first range the same when you add new ranges. To add new ranges, hold R again and select a different range, and repeat the speed change actions. Click outside the range to exit the speed pop-up menu.

2. Speed up video without changing pitch in iMovie

As we saw in the steps for iMovie 10, if you select the Preserve Pitch checkbox, your audio will continue to play at the same speed as before you made the speed change to the video. This is useful if you want the old audio but want a faster video. Of course, you need to keep in mind that the audio track will stop playing when the video is over, so you'll lose the end bit. To avoid this, you can trim the edges of the audio track to match the duration of the video clip after speeding it up.

3. Change the video speed but not audio

This requirement is slightly different because, if you want to speed up just a portion of your clip, you will still want to retain the audio at its original speed so the other parts don't go out of sync. For this, just right-click a clip and choose Detach Audio. You can also use the (⌥⌘B) shortcut for this. If you want to adjust the audio after the modified clip, just use the Split function to split the audio track at that point and adjust it to sync with the remainder of the video.

4. Reverse Video Clips in iMovie

Reversing a clip, or playing the clip in reverse, is equally simple in iMovie 10. Similar to the checkbox for Preserve Pitch, there's a checkbox that says Reverse. Tick that box and play the video, and it will play from the end to the beginning. Again, as with the previous tip, if you want to retain the audio as is, you can detach it from the video before applying the reverse effect.
