Alright, my cousin and I this weekend ended up recording over two hours of video of personal interviews and a "psych session" which should make stuff very clear Socionics-wise. Except...I'm having major trouble figuring out how to do video compositing. I need to tweak the brightness/contrast/hue of a few videos (they're too dark), and I spent all day yesterday trying to find compositing software without any luck (I tried stuff like Cinepaint, Blender, Openshot, etc., but none of them want to work on my computer...

) And I'm also trying to compile a custom version of ffmpeg so I can convert my MJPEG videos my cheap-ass camera spits out into something more compatible with YouTube, but, eh, that doesn't want to work.
So if there's any fellow computer nerds out there that know anything about video compositing and Linux, any help would be greatly appreciated. (Windows help
might work too, but after banishing Microsoft from my house, it'd be quite difficult for me to get ahold of Windows again.)
