A 90 second tutorial on exporting 1080p widescreen (16:9) footage to Cinemascope aspect ratio (otherwise known as Panavision or Anamorphic Scope – 2.35:1 ratio).
In this example, I used 100 pixels on the top and bottom. TRUE 2.35:1 aspect ratio would be 132px on top, and 131px on bottom (or vice versa). The final output would be 817px tall.

☞ ASPECT RATIO CONVERSION METHOD:
To convert from any aspect ratio to a wider format (such as 2.35:1 or 1.85:1), all you have to do is
DIVIDE the WIDTH of your SOURCE footage (1920 in this example) by the final aspect ratio desired (2.35 in this example).
2.35 = 817 pixels tall
Your final output would be 1920×817.
✏ To find the amount to crop off the top and bottom, subtract your pixel number (817px here) from your source footage height (1080px) and divide it by two. If it is a decimal number (such as 131.5), even it out to whole pixels (i.e. – crop 132px from top, 131px from bottom).
✏ Here are some examples of aspect ratio conversion methods. These are all assuming 1920×1080 footage. If your SOURCE footage is 1280×720, your width would be 1280; if your SOURCE footage is 720×480, your width would be 720; and so on.
☞ 16:9 to 2.35:1 / Cinemascope / Anamorphic / Panavision Aspect Ratio:
SOURCE footage width (1920) DIVIDED BY 2.35 = 817px tall
Crop 132px off top, 131px off bottom.
☞ 16:9 to 1.85:1 / Academy Flat / “Flat” Aspect Ratio:
SOURCE footage width (1920) DIVIDED BY 1.85 = 1038px tall
Crop 21px off top, 21px off bottom.
As a ‘bonus’, here is the method for converting your 4:3 aspect ratio video to regular 16:9 widescreen (assuming 640×480 footage):
☞ 4:3 to 16:9 Regular Widescreen Aspect Ratio:
SOURCE footage width (640) DIVIDED BY 1.778 = 360px tall
Crop 60px off top, 60px off bottom.
