In iMovie 11, how do I export at my custom resolution/aspect ratio?

[Doju]

I see a few posts that say it will also export at the aspect ratio you imported at, but how?

I recorded a portion of my screen with Quicktime's screen recorder, and it came to a resolution of 680x812. I imported that into iMovie, as well as a 640x812 image at the end, but when I go to export, I only get this screen, where none of them are the resolution of my video, and it puts black letterboxing on the sides:

How do I do it?

Also, how do I get it to not degrade video quality?

I don't think iMovie can do that, you need something like FPC X for that.

This is accurate so far as I can remember but I haven't used iMovie in awhile. It tends to only allow the things that people would commonly do so gives basic dimensions. If I recall there are other export options though. I can look for you when I'm on my own computer.

As far as quality is concerned any changing of the size / compression is going to hurt your quality. Chances are compression already occured when you recorded your screen.

There's no need to double post. I put this in your post in Applications:

Use the Export Using Quicktime option from the Share menu. From the popup box, click on the Options button and then select the Size button. You'll find the Custom option there.
