Took an mp4 video and added a black fade to the beginning and end of it and then when I export it, the video quality is noticeably grainier and almost 4X the original file size. So worse quality and 4X more megabytes. Tried tweaking every setting I could think of that would be responsible for it but can't figure it out. Here's a screenshot of the settings I'm using. I have 1280x720HD selection for resolution because when I select "Current dimensions" it exports it as smaller than current and I don't understand why -- I know because I open the original file and it's bigger than the one I export from iMovie. Using iMovie '09 version 8.0.6. Would really appreciate your help to solve this!
