SHORT ANSWER: Use the Crop effect and set top to "90" and "91" or
vice-versa...
LONG ANSWER: Since 16:9 is a ratio, and the image size is 720 x 486, you
have a natural relationship you can use to create a true 16:9 matte.
Using simple algebra:
16/9 = 720/x
720*9 = 16x
6480 = 16x
6480/16 = x
405 = x
486 - 405 = 81
Split 81 into two equal top and bottom masks... Hence, use the Crop effect
and set top to "90" and "91" or vice-versa...

Subject: OT: 16:9 Help....Square guy in Letterbox Quag
Clients......I just love 'em.
Cut a :30 spot standard def for air. Tons of large images pan & scan and
some 35mm film. Mastered on Digibeta Standard Def 4:3.
Client wants to have their spot "Run in a Movie Theatre". Crazy.....I know.
Anyway, the Encoding facility naturally prefers Hi Def Masters, but will
accept a Standard Def 4 : 3 Master with 16 : 9 mask 480i. Exposing my
ignorance here, but how can I be sure that I am creating a true 16 : 9
Letterbox mask in DS. In Graphics, I typed the letter "I" in a font that
when sized to 525 fills my entire screen top to bottom. If I tell it to be
480 size, will this relate to the mask size?
BTW, I did try to create a new sequence in 16 : 9 and although the images
looked OK, the standard 35mm film did not.
ANY suggestions would be very much appreciated.
Thanks....Rick at naked eye
a very wet Rick thanks to Hurricane Katrina !
