I prefer using video clips to communicate and advertise. If you want to play with it and toy around with the movie maker, just use "test" just to see what you look like. I hate to be blunt but I have to be if I am going to be honest....
I highly doubt several hundred strangers care when you make a video clip that says "Look at me!" "I'm dancing guys, Im dancing!" "Whoop dee doo!" with your character posing/whatever. I certainly don't care and especially since there is a test button where you can see what it looks like without needing to show it off to everyone else, if you're just playing with it you should use the "Test" button instead.
If it is that important to someone that they have to show it off to their friends or something, they can learn to use a free-trial video-making/screen recording software, and upload the video to Youtube or something. I can almost guarentee you can probably do a LOT more to it (editing and camera angles) than you could just playing with movie maker if you try.
I just find it frustrating when I see video clips that say "Hi
" real quick and then cut out when I'm busy looking for something. Was posting that really necessary? Was it even that funny? No. And I again, I doubt anyone cared. Its frustrating when movie-maker has become the key way of communicating in Fluorite at a distance, and yet people still fill it with "silly stuff." Yes, its a game, yes you can relax, be goofy, whatever and no I cannot speak for the majority and can only speak for myself but in my personal opinion...do it to your friends in close range or through whisper. Not strangers who will probably be more annoyed than amused.
Just my two cents.
