I have several projects and inventions the development of which I would like to chronicle on YouTube, however I'm also aware of the risks in doing so as anyone viewing the videos would be able to steal the concepts shown before any formal patent is filed. Ideally I'd like to release most of my work under some sort of open source license that allows non-commercial and educational use.
My question isn't about what license would cover this, but rather: What license, if any, could I release the videos under that would immediately protect their subject/contents?
I can find many licenses that protect the videos themselves, but none that cover the subjects shown in the video. I would imagine something along those lines exists, as the videos themselves would also serve as proof of original development. I've tried finding information on this myself but can't quite seem to find exactly what I'm looking for, I hope someone here may be able to help me.
