Troubles with video downloads

So I used my camera to film our next episode "Colorado Smith and the Sandals of Jesus."  The video itself was filmed easily except I have to do a voice-over in one scene and I have to upload the video on a computer and I am very illiterate in computers.  Usually some other members of the Big Smile Productions edit the videos and put them on DVDs.  After this episode I'm leaving all the video stuff to them.  I have another scene where the camera wasn't stopped from it's recording in time and I have a couple of bloopers I want to put after the movie itself.
