A movie edited with a computer cannot be rewritten to the card or played
back with the camera.
Playback and Editing with a Computer
If you want to use commercially-available software to play back or edit the
movies, be sure it is compatible with MOV-format movies. For details on
commercially-available software, contact the software manufacturer.
You can play back movies on the
camera's LCD monitor. You can also edit
out the movie's first and last scenes, and
play back the still photos and movies on
the card in an automatic slide show.
To play back or edit a movie, use pre-
installed or general-purpose software,
compatible with the movie's recording
format.
