Once you have edited your movie, you need to share it. There are a number of ways to do this.
1. If it is small enough, you may be able to send it as an email or message straight from your phone or computer. It is hard to do this with larger files though.
2. You can upload it to a cloud service such as dropbox, google drive or copy and then share it with other users. This is more secure than some other methods, and good for large files.
3. You can upload to a video sharing site such as YouTube or Vimeo, and then send the url link to someone. If you do this, it is a good idea to set a password or make the video private.
