Help needed in posting a video

[Southsider]

I'd like to know how to post a video on a blog. i've got as far as clicking the film icon, entering the type of clip - RealPlayer and the name of the file, then I can't get any further. Please could anyone tell me what I'm doing wrong and how to put it right?
Many thanks

I imagine each website has its own method. Which website are you on?
