I am running into an issue with iMovie and the sizes in which my project is available to me. The first time I used it, the project finalized in all the sizes. I ended up going back and editing the project and now it only allows me to have the video finalized into "mobile" size; none of the others are made available 
I also went through just export, but again only "mobile" is made available. How can I get other sizes?? Want the video larger.
Thank you!
