Hi, Yesterday I took few videos with my iPhone and I imported them to my iPhoto library. I want to trim these videos to save HDD space. Some videos are about 1 minute long and the part I need is few seconds in length. I understand that trimming with iPhoto makes a modified version of the video and it still keeps the old video in the HDD. How do I trim the video and get rid of the unnecessory parts of it to save HDD space?
