Windows Movie Maker is a simple video editor that comes with various versions of Windows. You can easily speed up or slow down your video to get different effects. It should be noted that in some versions of this program the speed can only be doubled. You can even split and merge video clips to speed up some parts of the video and leave others as they are. Read on to find out how to speed up your videos in Windows Movie Maker!
Steps
Method 1 of 2: Windows Live Movie Maker

Step 1. Open the video in Windows Live Movie Maker
Import the video file into the program, and then drag the clip onto the timeline. If you only want to speed up certain parts, split the video at the beginning and end of the subclip to create a separate video clip.

Step 2. Click on the Video Tools tab
edit ". Find this tab at the far-right end of the navigation bar at the top of the window: to the right of the Home, Animation, Visual Effects, Project, and View tabs.

Step 3. Open the drop-down menu "Speed"
This menu is located in the center of the Customize tab: above Duration, to the right of Background Color, and to the left of Split.

Step 4. Choose how many times you want to increase the speed
The range of values in the drop-down menu is relative to the original video speed: 1x. If you choose 0.125x, then slow down the clip to 1/8 of its real speed. If you choose 64x, you will increase the video speed by 64 times. If you are unsure of which speed to choose, think about why you are speeding up your video.
- Choose the highest value (64x, 32x, 16x) if you are speeding up the video of something incredibly slow: sunset, snowman melting or plant growth.
- Set the speed to 8x or 4x to fit something very slow into a much shorter time frame of video: a snail crossing a road or a group of people building something.
- Set the speed to 2x - twice the original speed - if you want to speed up a normal scene without losing its meaning, or to fit a clip where something slow was filmed (but not slow enough to use multiple acceleration) in the desired time frame.
- If you decide to slow down your video, use a lower value for this: 0.125x, 0.25x, or 0.5x.

Step 5. Check the new speed
Watch the video and see if the faster speed matches your project vision. If not, change it. Don't be afraid to split a clip into several smaller clips, each at a different speed. When you speed up a video, you shorten its length, so it will be shorter on the timeline.
Method 2 of 2: Windows Movie Maker 2003

Step 1. Open the video in Windows Movie Maker
If you haven't already, import the video clip into Windows Movie Maker, then drag the file to the timeline at the bottom of the window. If you want to speed up the whole video then leave it as it is. If you want to speed up only a certain part of it, then you have to split the video into several clips.

Step 2. Open video effects
From the main storyboard window, click Tools and then Video Effects.

Step 3. Select "Speed up twice"
Scroll through the various video effects until you find the "Double speed up" option. Left-click on it and drag the effect onto the timeline, onto the clip you want to speed up. This will double the speed of your video clip.
There is no more accurate video acceleration feature in Windows Movie Maker than this one. If you need a program with more features, find another video editor

Step 4. Slow down the video to make it the same as before
If you make a mistake, just press Ctrl + Z or click "Cancel AutoFormat" to return the clip to its original speed. You can also turn on the "Slow down by half" effect. Go to the Video Effects tab again, and then drag the Half Slow Down effect onto the video.
