8K...
Yes and raw.
It allows for using normal quality digital camera lenses and a 4k output. It allows hand held shooting and huge amount of PC controlled stability and cropping as needed for straigtening horizons, pespective correction, shake removal, etc with zero quality loss with a 4k output. It works really well!
BUT you need a camera that can write 120fps 8K raw data, and a card that can allow a rediculous data write speed. It literally writes at a continuous 700MB per second continually! So almost a Gigabyte per second!
When it comes to crunching 8K raw, and doing image stabilisation etc on that data you need a SERIOUS machine with super fast drives, and at least a 3080Ti card. Mine is 128GB fast ram, 3080Ti, 4x 4TB 7GB per second write speed, and its overclocked to hell, runs all 32 cores at 5.1GHz continually and it bogs it down!
The resulting files are great. I only experimented a bit, but its literal movie quality output.
My camera card in the Z8 gives me 2 something minutes at highest data rates.
And it is this PRO 2tb card. Which really is a NVMe drive on the inside. It doesent slow, but literally burns your fingers.
https://www.newegg.com/sabrent-2tb/p/0D9-001Y-000B8Its rated for 1.8GB per second write speed... in a card! And it really can right to the end.
So 8K has its uses, even by you. Once you try the 8k raw and see what editing that it allows with the pro version of Davinci Resolve or similar you would be amazed. Remember the aim is a perfect 4k output. It allows you to throw away 3/4 of the pixels. So huge gains in post zooming, stability, and exposure with raw. etc.
Just like your photos. You shoot 45mpixels. But you dont alsways use all the pixels in the output. But with movies that offers even more opportunities with stability etc. And high speed shooting. So I can do crazy frame rates if not rw, or if 4k raw.
Yes. Where does it all end?
