The first thing you need to do upon selecting New Project is to import the materials that you would use into the current project's Collection. These could include still photos, video files, and audio files for background music. Once you have all the materials in the collection, drag them off to the squares in the Storyboard. You can either drag the materials into their order of appearance on your video or select them all and drag them off altogether and the application will put them in their respective boxes. You can then re-arrange them later according to your preferred sequence.
Once you’re done arranging your video contents, it's time to edit it by adding video transitions, video effects, and titles and credits. If you want a faster way, you can choose to Make an Automovie where you will be given a pre-defined set of video effects and animation to use for your video presentation.

To add video transition, simply select from the available transition effects and then drag it into the smaller box in the storyboard in between two bigger boxes which holds your contents. Video transition determines the animation/effect in between the display of two contents. Video effects on the other hand, put some animation on a specific content before it progresses to further content. To add video effects, simply drag an effect from the preloaded selection and drop it unto content in the storyboard.
To make your video more professional, you may add another slide that would contain titles and credits information about your video.
To complete your video, you may want a musical background by dragging an audio into the storyboard. You can trim this audio file to make its running time fit into the length of your video. Unfortunately, you are limited to trimming the beginning or the ending part of the audio file.
