    When I try to crop a 4:3 movie to 16:9 by using FairUse, I click on 16:9 button and it gives me the selection in the first picture below. But when I capture the window and recrop it with 16:9 ratio Photoshop (the second picture), it gives me a whole different selection!?

    Picture 1


    Picture 2


    Which selection is the real 16:9 and how could it be different?

    Sorry, my bad English!

    Here is what I meant...

    When I try to crop a "picture" with 16:9 ratio in FairUse and Photoshop, they give me two different looks, and below are the pictures...

    16:9 in FairUse


    16:9 in Photoshop


    The Original One (4:3)

    Are you using square or non-square pixels in photoshop ?

    If you want to crop from 4:3 to 16:9, just remove exactly 1/4 of vertical size measured in pixels and leave horizontal pixel numbers as they are. This doesn't depend on pixel type: you'll further resize the result of cropping to standard numbers depending on the type of encoding (with its 'square' or 'non-square' pixels).

    I'm sorry, I have no idea what that is, I just turn on Photoshop and use the crop feature as usual. So could you show me which pic above is in 16:9?

    I just want to know how should a 16:9 video look like, so that I could crop the selection better. Thank you very much.

    To Alex_ander: "just remove exactly 1/4 of vertical size measured"

    How do I do that and still center the selection in FairUse? And are the numbers in FairUse in pixel measure? Thank you very much for your suggestion!

    Easier thing to do is set your hdtv so it fills the screen so you lose 1/4 height of your picture.

  8. FairUse is assuming standard 4:3 DVD PAR. Photoshop is assuming square pixels.

    Assuming your fair use sample is correct 433/267 is an AR of about 1.62:1. Adjust that for 4:3 DVD PAR of 1.1:1 and you get 1.62 * 1.1 ~= 1.78 ~= 16:9.
