Great work and impressive videos!
I am always interested in details about posted videos, like build, lens, mm, card, settings etc.
For people interested in anamorphic, have you considered crop mode at something like 1328x1494 up to 1360x1530 with a 2x anamorphic lens?
That would be 16:9 with high resolution and at current maximum bitrate. Vignetting should be less than at 1584x1056 non crop mode. The quality may get higher, but you would get more zoom effect than the non crop mode.
I do not own any anamorphic lens, and would like to know more about them. It would indeed be nice to have that discussion at another thread.
