For the all new Kinefinity MAVO edge 8K camera, Kinefinity had to come up with a completely new recording media. On the Mavo LF – with its 6k resolution – the Sata SSD’s were already starting to bottleneck, and were struggling to keep up with the beefy Apple Prores codec’s, especially in 4444XQ and in higher FPS in open gate resolutions.
Just to get a general idea of data streams;
6K resolution is 2.5 times more data than 4K resolution, and 8K resolution is 4 times more data than 4K resolution.
Even though you can compress a 8k data stream; after too much compression there’s basically no 8K resolution anymore. The same goes for YouTube; When you think you’re watching 4k footage, it’s effectively not more than 2k at its maximum.
Compression will group pixels and make them act the same, so let’s not fool ourselves.
To process 8K and offer more freedom in encoding, Kinefinity upgraded their media storage to a NVMe M.2. based media card called KineMAG Nano. To assure that the full potential of these cards is enabled, MAVO Edge will feature a PCle 3.0interface which allows the whole-new KineMAG Nano to record footage at lightning speed of 10Gb/s. For those who are not too much into computer language 10 Gigabit = 1.25 Gigabyte per second.
Due to the usage of the relatively new NVMe M.2, Kinefinity was able to reduce the size of the KineMAG Nanoby50% compared to their previous media card. Thanks to the smaller form factor of the KineMAG Nano, the MAVO Edge is able to adopt the dual media slot design like KineRAW-S35, first-generation cine camera introduced in 2012.
The dual slots design of the Kinefinity MAVO edge allows for two KineMAG Nano’s to record the same clips simultaneously and form an extraRAID1.0 backup to avoid missing clips. Furthermore, two cards can record the main codec and H264 proxies separately, to make the post-editing workflow much easier. With those h264 you could opt for a so called Offline Edit.
NVMe M.2 & KineMAG Nano
NVMe M.2 is opposed to Sata ssd 2.5 inch not intended to be inserted in a traditional way. Therefor Kinefinity had to come up with a solid enclosure. Additionally, Kinefinity also offers KineMAG Nano enclosures so users could purchase and install third-party NVMe M.2 SSD on their own to save the cost for storage media.
Potentially most NVMe M.2 cards are faster than the PCIE 3 connector inside the MAVO edge can handle. To be more precise any NVME M.2. thats durable and faster than 1.25 Gigabyte per second (10 Gigabit) will be more than capable to be used inside the KineMAG Nano enclosure.
In comparison; most SSDs (like the old Kinemag) will provide Read/Write speedsi n the neighborhood of 530/500 MB/s. For comparison, a old fashioned 7200 RPM SATA drive manages around 100MB/s depending on age, condition, and level of fragmentation. A lot of NVMe drives, on the other hand, provide write speeds as high as 3500MB/s (3.5 Gigabyte or 28 gigabit).
To get an idea of how cost effective Kinemag Nano will be lets have a look at the highly regarded Samsung evo 970 NVMe M.2 card which retails for €94 euro ex. VAT. This card can write up to 2500 Mb per second (2.5 Gigabyte per second), so fast enough to be used in conjunction with the MAVO edge. We don’t know the pricing for the enclosure but it will be very cost effective since Kinefinity isn’t a company that monetizes their recording media.
Even though RAW yields more image data, because the debayering is executed outside the camera, Prores Raw is capable of being smaller in file size than its older Prores 4444XQ brother. Please note that Prores RAW HQ is not included in the picture and will be 1:3 opposed to 1:5. But as we can see the KineMAG NANO can handle Prores RAW effortless even at higher fps. So no more bottlenecks!
To round up lets do a small comparison with other companies who have their own recording media. ARRI for instances uses CODEX cards for their ARRIRAW with maximum write speed of 1 Gigabyte per second (8 gigabit). RED uses on their existing line-up (the Komodo will use CFast) the so called REDMAG with maximum write speeds of 300 megabyte per second (2,4 Gigabit). A REDMAG 480 GB retails for $1450,- and has to be used in conjunction with a Redstation ($195,-).
For now KineMAG Nano seems to be the fastest proprietary recording media around. And potentially this could even be faster with newer camera models enabling PCI-E 4.0 which can increase data rates by a number of 3.
The biggest question remains if we need 8k resolution and how we handle this amount of data and how we upgrade our computers in order to playback, edit, process and export 8K footage. Those questions will be answered in new upcoming GAFPA SCHOOL essays.
Stay tuned and Stay Save.
