Slow motion video quality.

[M-FFU]

I have purchased Sony Xperia XZ premium in chrome on 7th August 2017. I am having a great time with it EXCEPT for the super slow motion camera. The video quality is so so so so bad. At first I thought it was because of the artificial lighting but then it still is ugly while filming in natural light. I browsed some of the super slow motion videos on YouTube and found out that the slow motion videos they're recording are just magnificent and clear with high quality, they aren't even using natural lighting for it. Why is my slow motion camera so bad??? Is my phone defective?? What do I do now? It is so irritating. I am desperately in need of the answer.

This is how slow motion works. It needs a lot of light as it records at higher shutter speed(higher than 1/1000s). It would produce good quality under direct sunlight.
