This entire video was filmed (and uploaded) in XAVC 4K 4:2:2 10bit at 24fps. It was recorded entirely on a Sandisk Extreme Pro V30 SDXC card. No new CF Express Type-A, no V90 SD cards. Just the good old classic. Before you swap all your cards out for hundreds of dollars of upgraded SD cards or new CF Express-A Cards, consider what you normally film and you may find that these "old" cards will handle 80% of the work you throw at them. Summary: V30 Cards are Capable of XAVC S (H.264) and XAVC HS (H.265) At 4K, 4:2:2 10bit at 24, 30, and 60 fps. V60 Cards are Capable of all that AND XAVC S (H.264) and XAVC HS (H.265) At 4K, 4:2:2 10bit at 120fps It's only for the XAVC 4K S-I (all Intraframe recording) that the V90 and CFExpress-A cards are necessary. You can do quite a lot with your old V30's that served your previous cameras well. No one paid me for any of this nor gave me anything for free. I paid for all of this with my hard earned money.
