Imovie issues

Unfortunately I have been facing some problems with uploading clips to IMovie. I have been editing everything on my own laptop so I am going to try and put  my movie on a memory stick and put it on the school computer, then try to upload it to YouTube and my blog that way. However, because of this issue I have been unable to show progress of the making of my short film as I needed to continue with the editing to get it done as soon as possible.
