Ann Bens Apr 10, 2012 12:05 PM (in response to Greg Popp)You need to make a new matte in the Titler or Photoshop. Each black bar should be 132 pixels in height.

1. Do the math on the ratio for the footage you have, in this case 16 divided by 9 = 1.7777
2. Take that ratio and divide it by the ratio you want, in this case 2.35*, which comes out to be .7565
3. Multiply that number by 100 for a percentage, in this case it rounds out to 76%.
4. Subtract that percentage from 100%, you get 24%.
5. Divide that percentage in half, here it would be 12%.
6. Apply a Top and Bottom Crop using that percentage.
*On a side note, the theatrical standard has actually been 2.39:1 since the early 70s, even though people often still call it 2.35.

3. Re: 2.35 widescreen letterboxing
dimakop1 Apr 10, 2015 4:34 AM (in response to Jim_Simon)That's a really convoluted way to do that.
This is easier:
Take the DAR (display aspect ratio) and divide it by 2.35
4096 / 2.35 = 1742.
So actual visible area would be 4096x1742.
Then minus 1742 from 2160 (height of 4k) to get what is left of black pixels.Divide that number by 2 to get the top and bottom numbers evenly.
