Blurry footage

[mihalis19]

Hello guys. I want some help.
I made my first footage and i edited it with premiere. I know i have a lot mistakes but its my first.
I shared the link in a facebook page for telling me other users better than me theri advises.
One guy told me something that i didnt noticed it, at some points i have blurry images.

0:51 at left side
3:30 at right side

Is that a focus problem of my settings?
Is that a mavic problem?

Also he told me that the horizon is not ok. Probably i have to calibrate it.

Please give me your advises

Thanks

Just looks like compression artifacts, could be casued by your editing process.
