Hello! I've made my first parody and it's entitled "Hitler's Most Shocking Discovery." I Hope you liked it!

:

Hello guys yeah my name is ybitte and yes I am very inspired by many untergangers out there how they and I'm looking forward to become another unterganger.

In a few days I'll be making a new movie parody of Untergang (just planning.) Definitely a movie it will take one hour long but into different chapters, I wonder if it's alright if I make one. There would be parts from Der Untergang scenes and some from Valkyrie. I hope no copyright claims, but if there are can you guys give me some suggestion on how to deal with it? Thanks. 

Questoins:

1. Is it okay for me to make 1 hour Downfall parody but separated into different videos (which means different chapters?)

2. How will I deal with copyright claims in Youtube since I'll be uploading videos here and youtube. (only if in case it pops out.)

Thanks!!!
