Blackmagic Design Introduces a $895 4K Disk Recorder / Monitor

Blackmagic Design just introduced their first 4K disk recorder / monitor, challenging the Atomos Shogun recorders with a high resolution 1080p display and SDI / HDMI connectivity at an impressive pricepoint of just $895.

After Atomos surprised us with yet another version of their high end HDR disk recorder, the Atomos Shogun Inferno, Blackmagic seems to be right at their heels with the new Blackmagic Video Assist 4K. What is interesting about this 4K SDI / HDMI recorder is mainly its price of $895. In comparison, the original Atomos Shogun is still $1495.

Video-Assist-4K_LeftSideAt this point, I should also mention that the while the Blackmagic Video Assist 4K shares the SDI and HDMI connectivity of the Shogun, the Atomos has gone through a year’s worth of numerous firmware updates that have made it a very feature-rich tool. Just like the original HD Video Assist, I presume the Video Assist 4K is still very basic in terms of its features.

If you’re searching for basic functionality though, the Blackmagic Video Assist 4K looks like a pretty interesting deal. It also offers a few nice features: it records directly to affordable and compact UHS-II SDHC Media and can even record to both simultaneously for a quick backup solution. Also when one card is full it switches over to the next card for continuous recording.

There are also 2 mini XLR connectors for audio, including 48V phantom power for microphones and last but not least LANC control and HDMI and SDI rec-trigger: a very important feature when you’re working in the field and want to be quick as a single operator shooter.


The 6G SDI input will enable recording from some of Blackmagic’s new cameras for a higher data rate. In comparison, most other camera manufacturers still use 3G-SDI that cause problems when working with 4K footage, degrading external recordings like on the FS7.

  • 7 inch LCD touch screen with 1920 x 1200 high resolution monitor.

Now if you could get BM size with Atomos brightness that would be something. Or get rig of the monitor altogether.

Hope this one handled highlights better than the 5inch

Jason Fisher-Jones August 24, 2016

The highlight issue has been bothering me on the five inch. Could this be fixed with firmware?

Firmware update is certainly recommended. Let us know if this fixed the problem though. Thanks

Jason Fisher-Jones September 3, 2016

My firmware version is 2.1, which I think is the latest. But still the highlights are very clipped.

great article and interview

Evan Shaw April 19, 2016

I could be wrong but just like the Video Assist it does not work with cameras like the Canon 5D mark iii that have clean HDMI out but no audio and need an input and lag correction. Atomos has this ability. BM does not it appears once again. I wrote to them about this and they said it would be corrected. Hmmm.

Evan Shaw April 19, 2016

I may have to take that reply back, there is a work around it appears. My bad.

Well, an important difference with the Atomos Shogun Assasin is that you record on an SSD reorder, not an SDHC card.
