It totally depends on what framerate you want to shoot. Roughly just add a zero to your framerate EG: 25 fps = 250megabit, 60fps = 600megabit Then divide by 8 to get megabyte which is what the class rating is. EG: 30fps = 300megabit = 37.5megabyte/sec So a v30 wouldn't be enough but a v60 would be MORE THAN ENOUGH, BABY!!!
There are two other use cases for CF Express type A (which I use every week for 3-4 months): 1. Shooting longer than 12 hours continuously on a Sony a7S3 at 4K60 fps at 200 Mb/s. To do this, you need two 1TB Type A Cards which will give you 13 hours with no overheating outdoor at 75 deg. F. The cost of 1TB CF-A is $500 (total $1000) whereas the cost of comparable v90 SD card is twice that of CF-A (you need 4x512GB (@$500 ea. or $2000) because there is no 1TB v90 SD card); you can get v60 1TB SD card at $300. With this CF-A VG200 card I can shoot 600Mb/s 4k60fps if needed. 2. Shooting longer than 8 hours continuous on Sony A1 at 260 Mb/s 8K30 fps. At 520 Mb/s 8K30fps I get 7.5 hours. The A1 will overheat in 40 minutes in sunlight 75F unless you have a fan like this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IFqYIwcExS4.html I'm switching over to CF-A (after 3 years now) because of the flexibility of getting the highest resolution when needed or the longest runtime. Cost as of Feb 2024 is better than v90 which is limited now to only 512gb per SD card.
Thanks so much for this video! I'm purchasing a second camera soon and hadn't heard of this brand before. I'll check them out before purchasing memory.
