One way is if you have an account on sims3 site. If you go to "my page" then "movies", any movies that you have made from sims3 is in that folder. You drag whichever file you want to the appropriate section. Then you go down to the next section for the audio. It has tabs and is pretty self explanitory. I know there are other ways to do videos, I would really like to learn and get into that aspect. You can also put whatever you do on the exchange from that same page.
