Import 720p to iMovie without clipping? I have some videos that were recorded at 720p which I'd like to edit in iMovie. They're saved as MP4s. When I import one and view it in the media browser, it looks fine. As soon as I add one to a movie project, the aspect ratio changes to... something else. The video gets trimmed at the top and bottom, and people's heads get cut off in some shots. How can I add these videos to a project and keep the entire frame? Ideally I'd have a movie project that matched the resolution of the clips. If not, can it be letterboxed to at least not lose any of the existing content?

I'm using iMovie 10.1.8. Thanks.

I'm not looking to crop, I'm basically looking to prevent unwanted cropping. In case there's any confusion, here are a couple of screen shots. The goal is to end up with a movie where nobody's head and feet get cropped out.

If I play the clip from the media browser, it might look like this:



If I add this clip to the movie, the same shot looks like this:
In the crop settings you should be able to select an automatic crop option or resize the video by grabbing and moving the edge of the video.
