Choose
the medium you are going to export your film to.
You can export it to DV tape and play it from your camera through a television.
This will give you the highest quality.
You could copy it onto VHS tape to play on an ordinary video player.
(This will only be half as sharp as a DV tape version.)
You could make a DVD (though not all DVD players can play all DVDs).
You could save it as a computer file to put it on a website or CD-ROM
or send it as an email attachment.
