Atomos Announces AtomOS 4.0 With Support For Avid DNxHD

Atomos, the creator of award-winning field recorders Ninja-2 and Samurai, announce that AtomOS 4.0 will support the Avid DNxHD production codec in addition to Apple ProRes. With immediate effect, Samurai owners will be able to download this new update, absolutely free of charge from the Atomos web site.

AtomOS version 4.0 for Samurai allows encoding to Avid DNxHD in the following formats: High – 220x/185x/175x Mbps (10-bit); Medium – 220/185/175 Mbps (8-bit); Low – 145/120/115 Mbps (8-bit). The firmware has been extremely well received by customers who have been invited to beta test it following a successful preview at IBC in September.

The Ninja and Samurai field recorders allow the recording, monitoring and playback of pristine, 10-bit uncompressed images straight from your DSLR or camcorder directly to Apple ProRes or Avid DNxHD.


The AtomOS 4.0 pre-release firmware for Samurai is available for download from the Atomos website with immediate effect. It is a full working version – the term ‘pre-release’ is used because it will be further updated to support Ninja-2 in late November.
