...don't know why you posted these, but for beginners' sake, i have to note:
Angle on- suggest another view of previous shot
C.U. Close up
...those are camera directions and should NOT be used in a spec script... it's stepping on the director's toes to specify any transitions or camera directions... only exception is if you're planning to produce and direct your own script...
CONT'D- when a speech is interrupted by a page break, type MORE in parentheses at end of last line on first page, then CONT'D after the characters name on the second page.
... seasoned writers arrange their pages/dialog so there won't be any dialog breaks...
POV- Point of view, being viewed from characters perspective.
REVERSE POV- If POV alternates between characters in a scene.
...these are also more in the province of the director than the writer and should be used as rarely as possible and only if absolutely vital to the plot...
theres more but i dont feel like writing a how to manuel.
...or a how-to pancho? [j/k
