Erin,

I think what HappyCamper was suggesting is that if you make sure you video camera has a stabilization
See Link: http://thewirecutter.com/reviews/best-video-camera/

What it means is the video will not be jump or shaking when your looking at it.

As for posting video on TER, I think you can post short Gif's but not  full length videos. You can post link to the videos, but you have done that before so I don't think that is what you are looking for,  I did find a few site that host adult Video that might help, but you will need to do some more research on them.
