Most funny thing I've heard thus far: you won't play a  game if your computer commits a false-positive virus check.

Take no offense, and give none.

happened to me to, but indeed humorous

this is exclusively for patreon subscribers, as the title says

eventually, it will be a public release, but this is spoilers in the form of a devlog

creator maybe wants the current progress to be known but not release freely yet

cost money to do so :P

let's be fair here, if they were a way to get the scenes, it would already be posted; BUT as much as I'd like to help you on this, you'll have to do some research, as the others said.

Either way, there are most likely several people who have gotten all the scenes, like me. Unfortunately, I have not seen whether 20/20/20/20 mode has such a scene in it. This game is relatively hard and  most people who play it would not want to share their progress. 
Most scenes can be unlocked after night 6 by losing to each animatronic (except g freddy) once.
Honestly speaking, just play the game. It's easy to beat night 6 once you learn each mechanic.

i don't think you can

Each character moves on interval. For instance, Freddy moves about every 25 secs on night 3 from when she starts her laugh. This can be delayed by watching her like in FNaF 1. 

Not a problem really. Stay off cams and use timers (i.e., a stopwatch) to survive efficiently. The 0.0.7 version made it pretty easy for timing Foxy and Freddy. I haven't been playing much since the update, but it should still work.
