I got some footage that was shot anamorphic 4X3 at 2.8k resolution. The request was to unsqueeze, which results in a 2.66:1 ratio. The request was to deliver 2.39:1 ratio, or 1920 x 803 by cropping the sides.
I created a new 1920 x 1080 deliverable that decoded the picture with anamorphic, using the color tool for framing and added a 2:39:1 mask.
In the color tab, when I opened the footage, I still had to set the aspect slider to 1.5 for it to look close to “correct” (as opposed to too tall and stretched). I adjusted the zoom slider to 0.85 since the edges of the picture should have been off the left and right edges in this scenario. I did not adjust H or V center settings.
My question: how do I use Cortex to exactly deliver what was asked instead of guessing and eyeballing? I tried to do some math regarding ratios but nothing I came up with looked remotely correct.
