FAQs
How many minutes of 12k video can be recorded with a 256GB memory card?
A 256GB card in the Blackmagic PYXIS 12K provides approximately 17 minutes of recording time when shooting in 12K DCI at 24 frames per second (fps) using a Blackmagic RAW 8:1 compression. Recording times vary significantly depending on the resolution, frame rate, and compression ratio selected.
What is the difference between CFexpress Type B 2.0 and 4.0?
The main difference is speed. CFexpress Type B 4.0 cards utilize the PCIe Gen 4 bus which delivers twice the bandwidth (up to 4 GB/s) compared to CFexpress 2.0 Type B cards that utilize the PCIe Gen 3 bus (up to 2 GB/s).
CFexpress Type B 4.0 cards are backward compatible with CFexpress 2.0 devices, meaning a 4.0 card will work in a 2.0 camera or reader, but the performance will be limited to CFexpress 2.0 speeds. Similarly, a CFexpress 2.0 card will perform at its peak in a CFexpress 4.0 device.
Are CFexpress Type A cards compatible with the Blackmagic PYXIS 12K?
No. The Blackmagic PYXIS 12K is not compatible with the physically smaller CFexpress Type A cards, only the larger CFexpress Type B cards are supported.
Where can you find the Blackmagic PYXIS 12K specifications?
Full specifications for the Blackmagic PYXIS 12K can be found on Blackmagic's website.
