Altering video altering is the cycle by which you take film that you recorded, slice and join it together to make a convincing film, short, educational video, class, or some other kind of video that you want. It is vital to have quality shots to work with before you head into the altering phase of your creation. In the event that the sum total of what you have is of low quality or doesn't convey what you had planned all along, then, at that point, you will be restricted in how viable the altering system can be.
