Aspect Ratio situation, Simple Math question

[boscomattel 0]

Hi there.

I have a porblem with some footage, the client filmed in Red cam 5K , 5120X2700 which is a 1.9:1 aspect ratio I think, and when they pass me the footage proxies they convert the 5120X2700 1.9:1 aspect ratio to a 1920x1080 16:9, so the proxies have a black letter box. :S

The final video needs to be 16:9 without letter boxes, the question is WHATS THE EXACT % OF SCALE I need to add in AE to eliminate those letter boxes?

Thank you very much!!

1920 / 5120 = 0.375
0.375 * 2700 = 1012.5

1080 / 1012.5 = 1.06666666666667

 

= 106.67%

Just to clear it up a little bit, the native aspect ratio out of the camera is most likely 1.85:1, the same as super 35. I would really be surprised if it was truly 1.9:1. Also for future reference, the F55 in 4k mode also spits out 1.85 material.
