What convinces you?
The movements of the camera from before to after the UFO is spotted do not indicate fake, to me.
They are the typical movements of an unprepared average person.
In the age of computers damn near anything can be faked, especially with a little talent, planning and thought. A few good witnesses coupled with the video would convince me. Keep in mind I do believe something is out there because I saw something on 2 occasions in my 62 years that I can not easily explain.
