Spectator camera glitch

Hi, I’ve got a strange glitch when using my specator camera linked to any character. The character starts shaking during the move. I’m attaching a video to show what I mean.
Spectator is pretty similar to the character actor as well, there is nothing changed in term of different movement setup or similar.

Video recorder in editor from the listened server view.
Would be grateful for any help or suggestions! Thank you!
