Question 1

What is SDI to NDI conversion?

Accepted Answer

SDI to NDI conversion transforms traditional Serial Digital Interface (SDI) video signals into Network Device Interface (NDI) streams. This allows legacy SDI equipment like cameras and switchers to integrate seamlessly with modern IP-based video production workflows, enabling signal distribution over standard Ethernet networks.

Question 2

What latency can I expect with MMG Axis SDI to NDI conversion?

Accepted Answer

MMG Axis delivers ultra-low latency encoding of under 30ms for SDI to NDI conversion. This makes it suitable for live IMAG (Image Magnification) applications, confidence monitors, and other time-critical production scenarios where delay must be imperceptible.

Question 3

How many SDI inputs can I convert to NDI simultaneously?

Accepted Answer

MMG Axis features 4 bidirectional 3G-SDI ports. Each port can independently encode SDI signals to NDI streams. All 4 channels can operate simultaneously at full 1080p60 quality with 8 channels of embedded audio per SDI input.

Question 4

Is the SDI to NDI conversion lossless?

Accepted Answer

MMG Axis uses high-quality 4:2:2 color sampling with alpha channel support for NDI encoding. While NDI uses efficient compression, the quality is visually indistinguishable for production use. The system supports full 1080p/i, 720p, and SD SDI formats with broadcast-grade quality preservation.

Question 5

Can I use MMG Axis with my existing vMix or OBS setup?

Accepted Answer

Absolutely. Once your SDI signals are converted to NDI by MMG Axis, they appear as network sources that vMix, OBS, TriCaster, and any other NDI-compatible software can receive. But here's the real power: MMG Axis is a full Windows production PC with dedicated GPU, so you can install and run vMix, OBS, or any production software directly on the device—giving you a complete all-in-one production system.

Question 6

What network infrastructure do I need for SDI to NDI conversion?

Accepted Answer

MMG Axis includes 10 GbE and 2.5 GbE network interfaces, plus WiFi 7. For reliable multi-channel HD NDI streaming, we recommend at least a Gigabit network, though 10GbE is ideal for maximum throughput when working with multiple streams at high resolutions.

Question 7

Does MMG Axis support audio conversion with SDI to NDI?

Accepted Answer

Yes. MMG Axis extracts up to 8 channels of embedded audio from each SDI input and includes it in the NDI stream. It also features stereo 3.5mm audio I/O that can be separately converted to NDI audio, and is compatible with Dante Virtual Soundcard for professional audio networking.

Question 8

Can I convert NDI back to SDI with the same device?

Accepted Answer

Yes. MMG Axis ports are fully bidirectional. You can configure any of the 4 SDI ports as inputs (SDI→NDI) or outputs (NDI→SDI) through the intuitive web interface. This means a single device handles your entire conversion workflow in both directions.
