To cut a video file into two pieces, play the video file and pause it at the place you want to cut it. Then, click the "Split" button below the video playing area, or press Ctrl+L. You can do this either in the timeline or in the "Collections" area.

To upload picture files, such as for a slideshow, click "Import pictures" and follow the same procedure. To reduce or increase the length of time a picture plays, drag the ends of the picture file in the timeline

To add a music or other sound file, click "Import audio or music". Drag it to the "Audio/Music" area of the timeline
