Review of software for Digital Video Editing

Until a few years ago, video editing was beyond the scope of educational institutions as to carry out expensive and sophisticated equipment is required in addition to the technical experts operate. The current situation is very different; first, a computer with a relatively affordable price can have the features and enough power to perform complex tasks that demand video editing and the other a digital video camera that can record on DVD currently available for a fraction of the value of the computer, depending on the brand and the features it offers, and the price continues to drop.

These teams open a world of possibilities to positively impact learning environments. Especially when you consider the fact that according to research, have demonstrated the production of video in interest and academic performance of students; they allow, among others, enriching activities such as Digital Storytelling or analyze real-world phenomena requiring determine variables such as position and time accuracy from a video recording.

The above are just two examples of the many ways in which the digital video can help enrich some learning. The basic equipment (camera and computer) can be practically used in all curriculum areas; therefore, the investment pays for itself very quickly. What must be borne in mind is that the need to meet certain software for educational purposes may vary. For example, in the case of the analysis of physical phenomena such as movement, a program that allows the student to mark the position of the subject or object moving in each of the frames from a video clip, in order to obtain the required information that automatically produce graphs of position, velocity, acceleration, etc.; but, for the Digital Storytelling, what is needed is an editing software that enables the mixture of photos, titles, voice, music, video and animation.
