Hey guys! Please acknowledge that I realize this question is really stupid so please dont be mean, but I wanted to make a OTH fan vid but I don't know where people who make fan vids get the clips or how they get them all put togethr with the audio.

It's not a stupid question.
Here's how I do it: I downloaded the program Freemake Video Downloader.
Then to get clips I download full episodes from watchseries.eu. These have to be converted into avi, which you can do with Freemake Video Downloader.
Once you have the episodes you can open them with windows live moviemaker. It's not as cool as sony vegas, but if you're new to this you should use windows live moviemaker.
To add music you just have to click the button that says 'add music'.
I hope this helped and good luck with your fan vid :)
