Downloading VideoCanvas free and the application is fully functional except that the exported movies and images are watermarked until you purchase it from the AppStore.
System requirementsVideoCanvas runs on Mac OS X 10.7.5 or later. For high-definition editing with multiple movie tracks you want to have a powerful computer, but small simple movies will work on cheaper and older computers.
VideoCanvas works with most popular video and image file formats. There is no functionality in VideoCanvas for transferring video directly from cameras, so you might need some other software for handling your video camera or DV-tapes, but you probably already have that either as included with Mac OS X or with the camera.
