Funny how we all talk about the URSA Mini Pro 12K having a lot of resolution for Super 35mm. Yet, 65mm Film is scanned at 12K uncompressed. That's 500 MB per frame, 11.72 GB per second, 703.12 GB per minute, and 41.20 TB per hour.
So, I'm wondering what would 65mm Sensor Size URSA end up being resolution wise using the 12K sensor from Blackmagic? I already did the math for the IMAX 15-perf size and got 31,822 px by 22,055 px. That means that the height for the IMAX would be the same as the width for 65mm 5-perf. So 65mm URSA 22K!
Oh, I like that. Now, I'm going with the original URSA body size to house this sensor. It makes the most sense. And, this is a beast of sensor I'd love to see. It would be more specialty for sure. But wouldn't it be incredible?!
And, with BlackmagicRAW the file sizes might be a bit more manageable. But you're going to need really fast media to store that data. Either fast SSDs or CFExpress. With the URSA Size you could do SSDs that get 2,000 MB/s Write Speed. Still, is that fast enough? Uncompressed 12K is after all 500 MB per frame! So that would only be 4 frames of uncompressed 12K with that 2,000 MB/s SSD.
Either way, just for some fun thought I'd share this all. Who else would love to see Blackmagic tackle a large sensor like a 65mm?
