"Making movies on the iPad is one of those activities that I often see in schools. I love to watch how quickly even very young students can produce a professional looking movie. It is a great way for them to illustrate what they have learnt. Normally I would say that editing movies on the iPad is best done using iMovie but it is not exactly cheap, especially if you have a raft of other apps you want your students to have. Here are a couple of apps for editing movies that do not cost the earth. Many of these apps also contain features found on the more expensive apps."
