I am new to this forum and English is not my mother tongue, so i would like to apologize for any grammar horror i will create.... I really do not mind if you feel the need to point out mistakes, this is how i can progress

I am an amateur writer, i wrote some short scripts for fun and to express what was boiling in my head.  I have a question if I may, i am working on a new script and i need to write a narration. I want a text to be shown and an off voice (off voice might be a bad translation from French) will read it to introduce the story to the viewers.  I know how to write the 'off voice', but how do i represent the written text un a movie script?

Thank you

Hello and welcome!  We native English speakers create “ grammar horrors” also so you are in good company, no worries.  As to “off voice”, you will see it titled “V. O.” (Voice over). Just identify who the speaker is and then place “V. O.” for what the character is saying.

Thank you kcranford. Voice Over makes a lot of sense.

Welcome to the site.

To have written text on the screen you would use SUPER: followed by the text you want to appear on screen.

SUPER is short for superimpose so you will need to establish a shot first so the reader/filmaker will know what the text is superimposing over.
It can be an actual scene or in can be black screen, either way that needs to be established first.

As an added note though, do you need to have the text on screen and a narrator reading it? Might be overkill
