Hi, I'm up for this show and need to know what I'm talking about.
It's a feature, they want to shoot at 2.35:1 aspect ratio, my question is what does the red actually record? Is the 4k frame a standard size, so to get 2.35:1 you just throw out the top and bottom? If so does it stay that way through the work flow, like when you color correct to a 2k DI are you matting out the top and bottom, and then to make a 16x9 pan & scan I'm zooming into a much smaller, in pixel hight, section of the 2k frame?
I'd much rather look like a newbie here than in front of the client!
Starting from build 17, the RED offers both options.
You can shoot with anamorphic lenses and use the full sensor or you can shoot with ordinary leses and crop out the top and bottom.
If they want to go for that specific look of anamorphic, like very different kind of lens flares and bokeh, you can keep the image anamorphic all the way through ( the projector will do the unsqueeze) or you could resize it to square pixels.
If you are limited to 2K in post, staying anamorphic will retain much more vertical resolution.
Hope this helps,
