Object entering camera frame, not smoothly, showing up of a sudden

Hey everyone, i really hope someone can help me with this weird issue i encountered for the first time while using UE 5.
Basically i have a camera sequence already set and i noticed that one of the animated objects, as mentioned in the topic title, enters the camera frame like popping in suddenly, not smoothly like other objects. For example the first frame, the object is outside of camera, while there is a big chunk of head appearing in the adjacent frame.



It’s not like a matter of speed as the movement of the animation is pretty slow and smooth actually, and other assets entering the camera frame don’t seem to suffer the same problem.
Any clue of what could cause this and how to fix it? Any help will be muchly appreciated.
I hope it was clear enough for you to understand and thanks in advance for any help i’ll get.
