Recording Devices Atomos Samurai and Ninja Blade

The Atomos Samurai and the Atomos Ninja are external recorders.

The Atomos Samurai and the Atomos Ninja are two of the recorders in the Atomos Blade series that can record full HD signals at up to 30fps. The most striking interconnection difference is that the Samurai has an HD-SDI interface, while the Ninja offers an HDMI port. So the choice of recorder will depend on which type of camera and output is providing the signal. 

The devices measure around 5 inches with a 1280x720 pixel resolution IPS touch panel screen. The screens on both devices can be used for monitoring the output. The devices weigh about 700g, including the batteries and storage media, and are suitable for rigging on small cameras.  Both devices can use relatively cheap and ubiquitous 2.5" SSDs installed in disk caddies docked to the recorder. Normal 2.5" HDDs with 5400-7200 rpm are also compatible. However, SSDs are preferable to HDDs due to the higher throughput and greater resilience to shocks or vibrations. 

The Atomos Ninja Blade is often paired with HDSLR cameras , although these often only offer a Micro-HDMI output. This interface may not be suitable for day-to-day production use, due to its mechanical design; frequent plugging and unplugging can cause loose connections. When using a Ninja Blade via HDMI, it is advisable to pay attention to the cable connection. 

The signal is 4:2:2 which is stored as a 10-bit or 8-bit sample, depending on the camera used. The material is then presented in edit-friendly ProRes or DNxHD , both of which offer many options in post-production.

Depending on how the output ports of the cameras are configured, it is possible to connect the Samurai or Ninja with a data rate up to 220MBit/s and encode using these devices so that the recordings are compatible with virtually any workflow, rather than the native recording format of the camera itself.   

In addition to the recording and monitoring functions of the Samurai and Ninja devices, they also provide built-in signal measurement tools including a waveform monitor, a vectorscope, a luma / RGB Parade, Focus Peaking, Zebras and a False Colour Mode.
