Operating system

64bit Windows 7 or higher

CPU

Modern 64bit CPU with at least SSSE3 support (i3-8100 or better recommended).
Full NDI (not HX) streams are recorded with minimal CPU usage, without any transcoding.
NDI|HX sources are transcoded to the full NDI's codec, which entails higher CPU usage.
Please use the free Trial version before buying, to check if your CPU is sufficient to record as many sources as you want.

GPU

Dedicated or integrated GPU supporting OpenGL 4.0 or higher.

Storage

Multiple high-capacity HDDs or SSDs may be required, in general:One 1080p60 source needs up to 25 MB/s of writing bandwidth and up to 90 GB per hour of recording
One 4Kp60 source needs up to 50 MB/s of writing bandwidth and up to 180 GB per hour of recording

You can verify the performance of your drives with appropriate software (look for continuous writing speed).

Network

Multiple aggregated 1Gbit ports or one 10Gbit port may be required to record more than four 1080p60 or more than two 4Kp60 sources.

Additional software

NDI|HX driver is required.

For playback and transcoding VLC and tools based on FFmpeg are recommended.

Compatible editing applications include After Effects® CC, Premiere Pro® CC, Prelude® CC, and SpeedGrade® CC.
Adobe® Creative Cloud® membership may be required. NDI Import I/O for Adobe CC plugin, a part of NDI Tools, is required.

Recording sources with varying parameters

NDI sources are captured without any transcoding or processing. Because of that, whenever a recorded source changes its parameters (resolution, frame rate, or the number of audio channels), the recording is stopped and a new file is started. This can affect recordings from Skype and vMix Call, which are known to change the resolution of their NDI outputs during calls.

Such recordings can be easily synchronized in Adobe Premiere Pro® by following this video guide: How To Sync Video and Audio To Timecode In Premiere Pro.
