Chapter 04 - Summary

Chapter 04 - Aspect Ratio

standard aspect ratios:

tv/computer screens - 1.33:1 (4:3 or academy standard)
16 mm film/european projection - 1.66:1
american projection - 1.85:1 (standard ratio, post 1950's)
widescreen super 35- 2.35:1 (70 mm, widescreen, cinerama, cinemascope)
high def - 1.78:1 (16:9)
IMAX - 1.43:1

How to compute the aspect ratios into storyboards:

take the aspect ratio and multiply it by the number of boards you want.

ie: for a high def storyboard with four shots - 1.78 x 4

Letterbox format presents the film as it was filmed but is cut off with black boarders on the top and the bottom. about 1.85 or cinemascope film.
Pan and scan is the reformatting of the original composition to fit the aspect ratio of 1.33:1 of TV.
