Your email address does not show in your post. There are a couple of different ways to get a large video from your phone.

Depending on your phone, you may be able to plug it in to a computer via a USB cable(sometimes your charger doubles as a USB connector cord). If you can, it is just a matter of finding the video and saving it to your computer.

You can also upload the video to a Cloud service such as Skydrive or another Cloud service, and provide open access to others via a link to the Skydrive folder.

Let me know if those options are not helpful, and thank you for offering your video :-)
