The left one. I mean the slowmotion effects, while other parts go faster, make sopme parts black/white etc

Bump for you dreetje!

I see no strange effects.
You make content... so you should know that already.
It's just some video/photo superpositions. The other stuff is just fast/slow efects.

any editing software can do that... including windows movie maker that comes for free with Windows.
