If there is no IMDb entry (
but please, only then), you can create an 'internal' movie title:
In the
upload form, next to the field "IMDB ID" there is a link "Add new movie".
Click on this link and do a search.
At the bottom of the search result list, click on the button to add it to the database.
You can now upload using this movie ID.
Please, make sure the movie title is spelled correctly and the year of release is given.
