Steps to speed up and slow down video with Wondershare Fimora 9

Step 1: Add required video files

The first thing to do is to open the Filmora9 video editor and add your required video files. To do so, click on the Import button from the media library. The entire files on your PC will be displayed, select the required video file, and click done. An alternative and easier method would be to drag and drop your video file directly into the video editor and under “User Album.”

Step 2: Speed up / slow down with one click

From the “User Album,” drag your video to the video track on the Timeline. Right-click on the video, a list of options will be displayed, click on “Speed and Duration.” You should see a pop-up window where you can adjust the speed with the use of numbers. 1 indicates the original speed, 2 means two times the original speed, 0.5 means half the original speed. Generally, the higher the number, the higher the speed. Numbers below 1 will allow you to slow down the video. You can easily view the effects via the preview page before saving and exporting.

Alternatively, an easier and faster method would be to drag the speed slider. Dragging to the right will speed up the video, and to the left will slow down the video playback.

Step 3: Adjust the sound of the audio.

This third step is optional but useful. When you change the speed settings of a video file, the audio speed automatically adjusts to suit the new video. However, if you would prefer to keep the original audio speed sound, you can do so in a few steps. Remove the audio from the video by double-clicking the audio clip. You will find the audio clip in the audio editing panel where you can also remove background noise, fade in or out or add new audio entirely.

Step 4: Export video file.

After making all adjustments to your video file, the final step would be to export it. Click on the export button in the video editor. You also have the option to save in any video format as well as the option to save and play your video on any device you wish to: iPhone, iPod, iPad, or share directly to YouTube and Vimeo.
