So you are saying that we should shoot h.264 YouTube ready? or 720 by 480 DVD format? Do you understand why Black Magic and digital camera have the RAW format? Acquisition. That is, you have one chance to capture the image, so you better do it right. Even Kodak says editing should be performed in the digital world and that's exactly the same reason for BMD and Alexa and RED to have a RAW code. You should grab a book and stay away from you tube "filmmakers" channels you old "been around" digital man.
That's true. They are afraid of shooting film so they lie to themselves saying film is death, it doesn't look good, is not 4k. Happily I see where things are going. They did it before and they are going to do it again. Back in the day cinema invented 1:85 when tv appeared. They said it was dead then; it wasn't. Cheap fx like wipes and circle dissolves.. Pros stopped using those as soon as they were available to masses. Now everyone is a DP, a Cinematographer or a Filmmaker with a t2i. Everyone "can" shoot digital... But not many people can shoot in film. with by the way is better than ever before, and just ready to keep going after 120 years of being around.
And you are shooting another 5D M7 vs BMPSC 8k noticing how the zeiss lenses look "sharper" compared to the rokinon ones... The modern "filmmakers"
