Correcting Cinemascope Without Fully Stretching the Format
Hi
Is there any way to take 2:35:1 footage into after effects and warp it so it fits a regular 16:9 aspect ratio?
The problem I am facing is that there is quite a spherical object that I can’t have warping, but it’s central enough to warp the further out areas of the Cinemascope…
You see a similar effect being used to refit 4:3 into 16:9 on most HDTVs… This works horizontally though… So how would I go about doing it vertically?
Thanks

There is no way to “warp” the footage that will look correct.
Fitting 4:3 aspect ratio into 16:9 is done by centering the image in the frame and adding black bars to each side, or by scaling the image beyond the frame and cropping the top and bottom of the 4:3 to see the central part of the original image.
To fit 2:35.1 into 16:9 aspect, you could invert the strategy and add black bars to the top and bottom, or scale the image and crop off the sides.

Yes, Chris
That is what I want to do
Luckily my footage is primarily shot on 10mm & 15mm lenses so distortion will go largely unnoticed.

Well, if distortion is acceptable….
Mesh warp is one way to do it. Set up a 2:35.1 comp with your footage, add mesh warp, then drag individual points on right and left side out to the edge of the frame. You may want to slightly spread them vertically to give a more spherical image.
You’re almost tripling the width of your image, so you could also experiment combining mesh warp overlayed on top of an enlarged and blurred copy of your footage.

I published an AEP to do a non-linear stretch from 4:3 to 16:9 a while ago, which you may be able to adapt to your needs:
