iMovie 11 bug?

[computerpro3]

This is pretty strange, but it's extremely possible I'm just doing something wrong since I'm new to Mac.

I'm trying to edit some footage of the Baltimore Grand Prix. I have a shot of the starting grid roaring by and want to trim it from over 1 minute down to 16 seconds. So, I go ahead and trim it down and then try to export it to Finder.

The original footage is 1920x1080. If I export it at 1920x1080, NONE of my edits are saved and it comes out as a 450mb 1:23 long file. If I export at 720P or something else, it comes out properly as a 16 second long, 30mb file.

Any ideas or is this just another instance of Mac "Just Not Working?"

Can you confirm if this is isolated to one mac? Do you have a 2nd to test with? Do you have all the latest updates for iMovie installed?

This is my only mac. I do have all the updates installed.

Have you done this before?
