I've seen the two seasons on Crunchyroll but this looks like content I've never seen. If this is from other seasons, do you know where I could watch it?
I didn't immediately recognize the scenes with the Egyptian and Japanese magical girls.
There's a movie series - Puella Magi Madoka Magica: The Movie - that's something of recap of season 1-2. The "Rebellion" arc is a season 3, of sorts, that officially ends the series. Some of those scenes might be from there.
Actually, there's also apparently a 4th movie in the works, the trailer for which has been out for a while.
