iMovie is the video editing/creating software on Apple (Mac) computers.
Watch this excellent video for detailed directions on the steps to create an iMovie project -- Be sure to watch this before making the video!!!
***Crucial tips to keep in mind when using iMovie:
Create a NEW FOLDER on your H-drive (or on a flash drive) for your project and save EVERY image, audio file, video clip, etc. you will use in the movie you are making AS WELL AS THE PROJECT ITSELF to this folder. You must save the PROJECT FILE and each EVENT FILE (event files include videos, pictures, music, etc) to your H DRIVE.
AVOID PLAGIARISM: Cite every source you use for your project (unless it's your own, original work) and include a "Works Cited" slide in your presentation
AVOID COPYRIGHT INFRINGEMENT: If using copyrighted materials (such as images you find online and songs) you must give credit to the sources and include a fair use copyright statement in your project
Do not steal music! Use GARAGE BAND to create music for your iMovie.
