Sorry for the delay, SpaceEngineer
Well if you could just write something like
"I give permission to Christian Leonard for the commercial and non-commercial use of footage from my program - SpaceEngine
<Signature> "
Tha would be great!
Thanks a lot

I don't know when I'll start producing the next episode, or what it'll be about, but it's certainly an ambition of mine to do it soon.
Again, any suggestions as to what I might focus on, are greatly appreciated!
Take care, SE community!
