Problems in video editing. Because we interviewed 3 people and each person was interviewed more than 10 questions when the video editing in the beginning, our video have length More than 10 minutes.At first, we still do not know the length of the video was defined, we asked the teacher to make sure.the teacher said length video is 5 minutes so we edit video again and The problem we found is that the voice of those interviewed were not clear. Our solutions are accelerating their voice to be even more.
