very nice job for your first video!!!

It was a good length, too. Not too long to bore the viewer but long enough to show different aspects of the dive - a bit of topside, a bit of reef, a bit of fish, a bit of divers. It was nicely organized, also.
I do have a couple of comments to help you.
1. Slow down with your movements. Topside and underwater, try to go as slow as you physically can, this takes practice but you will see a big difference. I think this is the hardest thing that about underwater videography and it is what everyone needs to work on.
2. Panning is okay if scene is static, but you don't want to pan when the objects are moving, like people walking, etc. Also, don't pan too much! The first part of the video you pan left, then follow it with a pan right, then a pan left again. That is just too much movement for the viewer's brain and can make them seasick! :shocked2:. Let people walk in or out of the frame instead of you moving the camera. And don't put 2 panning shots back to back. Make sure you have a static shot or two in between.
3. I really liked the shots underwater where you are spinning around the other divers. (Dolly shots) That is a good example of what I was saying about panning - diver stationary but you move.
4. Have fun!

You said that you spent most of the time just enjoying the dive and that is GOOD. You don't have to shoot video of every little thing, be a good safe happy diver first, videographer second. That is my rule!
