How to slow down a video

Slowing down or speeding up a video

Slowing down or speeding up a video

With the information window

  1. Double-click a video clip in the project overview. You can also select one or more video clips or a range of images and then double-click to open them.

  2. Do one of the following:

    • In the Clip section of the Inspector, move the Speed ​​slider left to make the video play slower or right to make the video play faster. The further you move the slider, the greater the change in speed.

    • In the fields to the right of the Speed ​​slider, type the percentage of normal speed for the clip or set the duration of the clip in seconds.

    If you see the Convert Entire Clip button instead of the Speed ​​slider, click that button. Certain types of video (such as videos recorded on iPhone or H.264 video from a flip camcorder) must be converted before speed changes can be made. After converting the video, you can use the Speed ​​slider as described above or specify the percentage of normal speed.

If you change your mind later and want to undo your changes, you can always open the Inspector and reset the speed or direction of the clip. Then click on "Done".

With the menu "Clip"

  1. First you have to select one or more video clips or a range of images in the project overview.

  2. Do one of the following:

    • To make the clip play more slowly, choose Clip> Slow Motion, then choose the percentage you want. Available percentages are 50%, 25%, and 10%.

      The Clip menu is located at the top of the computer screen in the light gray menu bar.

    • To make the clip play faster, choose Clip> Fast Forward. Available multipliers are 2x, 4x, 8x and 20x.

      If one of the options cannot be selected, it means that the video clip is not long enough for this increase in speed. However, it can also mean that your video needs to be converted. Certain types of video (such as videos recorded on iPhone or H.264 video from a flip camcorder) must be converted before speed changes can be made. Double-click the clip in the project overview. If the Information Window that appears shows a Convert Entire Clip button, click the button. Then choose Clip> Slow Motion or Clip> Fast Forward.

If you later want to undo the changes you have made, you can do so at any time by double-clicking the relevant video clip, or by selecting one or more clips or a range of images. In the Inspector, drag the Speed ​​slider to reset the speed of the clip, and then click Done.

If you move the pointer in the project overview over a video clip whose speed has been changed, you will see an icon on the left edge of the clip (see the following examples) that has the following meaning:

  • Rabbit looks to the right: the clip has been accelerated.

  • Turtle looks to the right: the clip has been slowed down.

  • Rabbit looks to the left: the clip is played backwards or both sped up and backwards.

  • Turtle looks to the left: the clip plays backwards and slows down.
