Now, what if you want to upload that video to Youtube. Youtube doesn’t recognize the mask and keeps the letterbox. How do you crop to the mask?

Can I do this in QuickTime X?

If your video isn’t the exact size youtube wants, it will process it with the additional letterbox to make it fit.

This was really helpful and worked great IN quicktime. I’m having the problem though that if I export it doesn’t save/apply the mask and if I try to upload to youtube my video goes back to having the black letterboxing. How do I fix this?

Hi Dave,

I found this really useful and would have never worked it out for myself. Thank you.

Now I’d like to know how to do the reverse (sort of). I have a video in a scaled size window of 441×248 (16:9). Now, for some reason the video seems to be in some kind of super widescreen format (it’s somewhat squished), and so I’d like to stretch the video but keep the scaled size the same (i.e. keep the window 441×248. So I need to add a letterbox. I have looked everywhere but can’t find how to do this. I have QT Pro and iMovie – and Photoshop on a trial.

Your help much appreciated.

Thanks,
Dan.
