The recording resolutions on the BMCC6K are not very friendly towards shooting with 1.33x anamorphics. I spent sometime this afternoon going through the reductions I can use for capture to deliver 4K and 2K anamorphic video. One is forced to discard a lot of height on the captured video. The BMPCC4K is much more efficient in that regard.
Option A
Thanks to the SLR Magic APO original primes having an image circle of 46.3mm, I would just barely be able to capture 4K anamorphic 1.33x squeeze shooting 4838x4032 for good quality colour 4096x1716 deliverables.
Option B
With room to spare, it’s easier to capture 1.33x anamorphic 4096x3072 for 4096x1716 deliverables.
Option C
For 2K, I’d efficiently capture 2112x1184 for 2048x858 deliverables.
I’ll have to test these to see if I can discern any quality difference particularly between option A and B.
I’m used to capturing Super35 which uses the sweet spot of my primes. Option A will take me right to the corners of the image circle of my primes; if that looks bad, option B will work well.
Now I think I need to pray for one software change regarding anamorphic selection. Currently BMD assumes some default squeeze factors such as forcing a 2x squeeze in the menu selection if the aspect ratio is 4:3 or 6:5. I need less AI and more common sense: please let me set the squeeze factor I want for any resolution. I’m hoping they’ll do that at least for the newly designed BMCC6K. I know several people want more choices for squeeze such as 1.5x, 1.8x; I’m supporting that as well as making the squeeze user selectable.
Thank you BMD for these great new cameras and the new functionality!
