Now that you've got your files on your computer and into a timeline in Windows Live Movie Maker, it's time to begin editing. Woo!
You can drag the files around in the timeline to set the order you'd like. This will help you create a coherent storyline and help you rearrange the video clips into the order you want. If you want to cut a clip, or shorten it, click on the place on the clip where you want to cut and a line will appear where you clicked. You can then click 'Edit' and use the 'Trim' or 'Split' tool to perform the action of your choice. Play around, anything you do can be reversed and you never edit the actual original video files, just copies of them.
If you choose trim, you can then choose your start and end points in the preview window on the left using the play bar below the video. Choose 'Save Trim' to save your changes. This tool is helpful to sort of trim the fat at the beginning and end of clips, or if there is a mistake, in the middle of a clip. It's easy to just cut it right out!
