Supers - Titles, Signs, etc.

A Super is something that is superimposed over another thing. Sub-titles are supers. But, for your purposes, a Super is more likely some descriptive text like a time or location or a translation.

Supers are written with Action elements.. For example:

INT. PENTAGON, WAR ROOM - DAY
SUPER - 10:15 Zulu, Present Time
The council gathers around the table.

What this means is that when we cut to the War Room, the words"10:15 Zulu, Present Time" will appear on the screen over the image of the council gathering.

Another example:

Marty looks at the sign which is in Arabic.
SUPER - Do Not Enter. Death Penalty Enforced.
                    MARTY
          This must be the place.
He walks in the door.

 

Titles

Some writers like to indicate when the film's title sequence should start and end by writing:

BEGIN TITLES
END TITLES

My opinion? Don't bother. Let the director decide where the title sequence happens.
