This is the only tutorial I've ever seen for making vids, and it's by our very own tcco94.

You'll need at least:
-FSRecorder, I find it easier to record the flight first, that way I can concentrate on flying, and then when using Fraps, I can concentrate on the camera work. (also allows for more unique camera angles.
)
-Fraps (demo is free, but only records 30sec clips, which is more than enough for me.)
-Windows Movie Maker, or something similar, load your fraps clips into this and edit & add music and save to an uploadable format. (WMV works best for most.)
SimV-TV has a 500mb upload limit, but that should be plenty. I've made a 15min video with 3 different songs in it, and never got close to that limit.
There is another thread here with a link to a program that will compress Fraps clips, thus making the end result much smaller in size without hurting quality, I'll see if I can find it.
Hope this gets you started.
