PYXIS 6K: Blackmagic RAW bitrate & storage per hour

The Blackmagic PYXIS 6K records Blackmagic RAW. Maximum sustained write speed: 1000 MB/s. Figures per sensor mode and compression level at 24 fps — video only.

6K Open Gate (6048×4032, max 36 fps)

6K 16:9 (6048×3408, max 46 fps)

4K DCI (4096×2160, max 60 fps)

4K UHD (3840×2160, max 60 fps)

Content-dependent codecs (constant quality, VBR) vary their data rate with scene complexity — the figures above are typical values, and actual rates range around them.

Cards and recording time

The PYXIS 6K sustains up to 1000 MB/s, so its media has to keep up with the mode you shoot. At the highest rate in the tables above (336 MB/s) the recording times per card are:

Offloading a shooting day

90 minutes of takes come to about 1.8 TB. Over USB 3.2 Gen 2 (10 Gbps) that is 36 min for a single copy — double it if you verify with checksums, and multiply by the number of backups.

What hardware it needs

Playing this back in real time means sustaining 336.26 MB/s of reads. One hour of footage is 1.2 TB, and that is what has to travel every time you copy, back up or archive it.

Any card or drive rated below 336 MB/s sustained will drop frames on playback, whatever its peak speed says on the box.

Times are for a single copy without checksum verification. Verified offload reads back what it wrote, so it takes roughly twice as long.
