In which case use in Larvel OOP?

guys. In my project I have model and controller for posts. Where in post major field is picutre.

Now, I must have to type of post - where major picture and major video.

How I understand - I must create major model and controler for post with basic mehod and extend from it VideoPost and PicturePost.

It's correct? Or maybe exist other way to realize it?
