He seems to be talking about the visual content - what is going on behind the closing credits - maybe 'closing credit sequence' would work including both the credits and the graphics.

I think this could be what you need.

A post-credits scene (also called a stinger, tag, coda, or credit cookie), is a short clip that appears after some or all of the closing credits of a movie have run. It is usually either included for humor (where it may be called a “stinger gag”) or to set up a possible sequel, as well as to encourage the audience to stay through the credits during the theatrical release.

A name for any post-credits scene. It is also known as a "tag" or "credit cookie".
Often used to provide some kind of Sequel Hook, but may also be there just as a final gift to the audience, such as a comedy giving one final joke and punchline to the audience, or a dramatic work showing that maybe the guy who made a Heroic Sacrifice is Not Quite Dead. Or maybe just answering the question of What Happened to the Mouse?. There may even be a selection of Hilarious Outtakes, or a special ending screen.
