File Conversion

I have worked for nearly 2 hours trying to figure out what I can do to get this video "embedded" into my blog. So far, the program I was asked to download in order to convert my video caused my screen to go blank and I lost all work I had open on my screen at the time. The program scared me and I do not like downloading programs I am unfamiliar with. Aside from this, the link on our work page to help us learn how to convert did not show up. It kept telling me the link was disabled.
