How would one go about making something like THIS in HitFilm 4 Pro?

HoldMySoda Posts: 85 Just Starting Out*

I still have HitFilm 4 Pro and I should probably upgrade at some point, but it's too expensive for me at the moment, so how would you say I could create an effect like that?

Meaning, even after a few years of using this software, I have no idea how to add text/images/whatever in a way where it blends into the original as if it were actually there as see in the gif. I don't even know what that technique is called/what to search for, which is why I never bothered before.

Any tutorials you can point me towards? Thanks.
