You can trim the beginning and end of a video so your movie shows only the part of the video you want. For example, if you have a video with a few black frames at the beginning, you could trim the beginning of the video so the black frames don't appear in your final saved movie.
When you trim a video file in Movie Maker, the original video file isn't affected. All the video footage remains in the original video file.
On the Home tab, in the Add group, click Add videos and photos.
In the Add Videos and Photos dialog box, open the folder that contains the photos or videos that you want to add, select the video files and photos, and then click Open.
Click the video that you want to trim.
To select multiple photos and videos, press and hold the Ctrl key, and then click each photo and video you want.
Under Video Tools, on the Edit tab, in the Editing group, do one or more of the following:
To set a new start point for the video, drag the slider underneath the preview monitor to the point that you want the video to start, and then click Set start point.
To set a new end point for the video, drag the slider underneath the preview monitor to the point that you want the video to stop playing, and then click Set end point.
Click a trimmed video in your project.
Under Video Tools, on the Edit tab, in the Editing group, click Trim tool.
Do one or more of the following:
To make the trimmed video play from the beginning again, click the start trim handle underneath the preview monitor, and drag it to the beginning of the video.
To make the trimmed video play to the end again, click the end trim handle underneath the preview monitor, and drag it to the end of the video.
On the Trim tab, in the Trim group, click Save trim to save the changes you made and to close the trim tool.
To quickly trim a video in Movie Maker, play the video you want to trim, and then press the I key to make the current point the start point, or press the O key to make it the end point.
If you trim part of a video that has a caption, the caption is trimmed too.
