The video was shot on an iPhone.( I believe .mov format.) I tried to open it in iMovie on Mac OS but it won't open, it's grayed out. I could have shortened it, but cannot get to it. It will play in Quicktime, but I cannot edit it in iPhoto. I need to send the video through email (using yahoo, google, or aol) I have looked for compression freeware, but do not know exactly what I need for this. So what is best to use, it must be free or very cheap. Also I need to trust that it is safe to download. Thanks.
