How can you change the field of view / FOV on the Ps4 in COD (Black Ops 3)?

I'll show you that with the following link:

This guy plays on the console (PS4) and definitely doesn't have the standard field of view that is determined by the game itself. He changed it. Now I wonder how is that possible?

Maybe he is playing with controller on PC?

He plays on the console, look at the comments I asked him, but he didn't answer the question of how he changed his FOV

What should the comments tell me?

That he may not be playing on the PC but on the console

Where is it?

As I said in the comments. Have to filter by "newest" and scroll further down.

Just googled. On the PS4 you can't change the field of view https://gamefaqs.gamespot.com/boards/145061-call-of-duty-black-ops-iii/72808931

Yes, I already know that it is not possible. That's why I'm so amazed why it's possible with him. I also googled afterwards and most of the posts about it were 4-5 years ago. Maybe they changed that in time and I didn't notice anything, so I ask

Then have a look?

I'm about to find out or what do you mean why I'm asking this question here?

hes using pc gameplay and then showing the closing app on ps4.
