I've decided that vidding would be my preferred method for expressing my utter devotion to Sebastian Stan and all things Marvel Cinematic Universe, so what super cheap software does one use to vid? Please don't tell me to google because that results in a grab bag of irrelevant information, resulting in my simulating the gif below.

Also, with that, there are some vids on youtube that I absolutely adore but the sound is not stable; I adore them anyway but I'd like to avoid that pitfall if possible, preferably with the cheap software I'd use preventing that automatically.
