I was under the impression that when you shot at the other ratios, you merely used that part of the sensor and not creating a squeezed version of the footage.
Anyways, we were shooting 50fps at 1.85 and when I pulled in the footage in Premiere, it's squeezed in top/bottom.
The reason we chose that format was because we want the 50fps from the get go. Second we wanted to get as close to full HD as possible since we can just upscale afterwards without any significant drop in quality.
Is there a setting we forgot to put on or something. Like a "disable anamorphic" or something similar?
No, there is no such setting. 50/60p is always squeezed.
