to see if they have the housing. if they do, it should work.
as for editing, all i can say is it's about expression. you express through editing of your feelings about a certain shot or shots. there's no real trick to editing, but there are some keys.
1. the most important thing isn't editing, but camera work. get the angles. use a chase boat from different angles. don't limit shots to towboat shots.
2. always have the camera on to get all the shots. you don't want to end up saying, "damn, i should've had the camera on."
3. keep the camera steady. use both hands to film. for land shots, use a tripod.
4. don't use the lcd screen.
5. keep your pans as smooth as possible.
6. it's best to film in the mornings and late afternoons. avoid filming in the middle of the day.
7. use good music. you can have the sickest footage in the world, but if the music isn't good, you'll lose the viewers.
8. practice filming. practice editing. once you're done, practice filming some more and practice editing again.
