The cameras I'm using are pretty high quality, so that's the main reason the video looks good.
As far as rendering video for the internet, it's always a trade-off of low file size(to save disc space and bandwidth) and quality. One of the reasons the video has no sound is to make the file size smaller. All you hear is the bait tank pump anyway.
You can download a free media encoder from Microsoft to render the WMV files if you're interested.
I've got lots more video, but the big wave season in Hawaii is a busy time for
my real job, so it's putting a little crimp in my creative flow.
