10 Best NDI Encoders for Broadcast (November 2026)

Buying the wrong NDI encoder usually shows up on show day. An HX encoder gets bought for a workflow that needs full-bandwidth NDI, an HDMI box arrives when the cameras output SDI, or a unit with no PoE ends up needing a power outlet at a ceiling-mounted camera position. Some devices also encode only, while others switch between encoder and decoder but never do both at once. The Best NDI Encoders for Broadcast depend on three things: the input type (HDMI or SDI), the NDI flavor (full bandwidth or HX), and how much streaming, recording and control you need on the same box.

The short answer: the Zowietek ZowieBox HDMI NDI suits anyone who wants a small, native NDI|HX3 encoder and decoder for cameras, consoles and PTZ rigs. The SZXLCOM HDMI Full NDI Encoder suits productions that want full NDI rather than HX, with a claimed latency under 60 ms. The Magewell Pro Convert HDMI 4K Plus suits studios that need 4K60 HDMI in and out with loop-through on a 24/7 device. The rest of the list covers a five-input encoder, SDI converters, a touchscreen unit with AI tracking and three Magewell streaming encoders with recording.

TL;DR: top picks at a glance

• Best overall: the Zowietek ZowieBox HDMI NDI, a 5.9 oz unit with native NDI|HX3 that works as both encoder and decoder and runs from PoE, USB-C or DC.
• Best for full NDI: SZXLCOM HDMI Full NDI Encoder, true Full NDI (not HX) with 1080p60, PoE and an HDMI loop out.
• Best for 4K60 HDMI: Magewell Pro Convert HDMI 4K Plus, accepts up to 4096×2160 at 60 fps and outputs NDI high bandwidth with loop-through.
• Best for SDI sources: Magewell Pro Convert SDI TX, converts 3G-SDI to NDI high bandwidth with up to 16 channels of embedded audio.

1. Zowietek ZowieBox HDMI NDI: Best NDI HX3 Encoder Decoder for Compact Camera Rigs

• NDI Support: Native NDI|HX3, HX2 and HX encoding and decoding
• Streaming Protocols: SRT, RTMP(S), RTSP, HLS
• Power: USB Type-C, PoE and DC output, tripod mount
• Weight: 5.9 ounces, aluminum body
• Extras: Tally light, LCD status screen, VISCA over IP PTZ control

Pros:

• The 5.9 oz aluminum body is smaller than a phone and mounts on a tripod or a cold shoe, so it disappears onto a camera rig.
• It works as an NDI encoder or an NDI decoder, which lets one unit cover camera feeds and confidence monitors.
• SRT, RTMP(S), RTSP and HLS are all supported, so the same box can feed an NDI network and a streaming platform.
• A web UI on a PC, phone or tablet controls PTZ cameras, tally, OSD and network settings.

Cons:

• Encoder and decoder modes cannot run at the same time, so a two-way workflow needs two units.
• It does not support full NDI, only the HX family.
• Feedback on reliability and audio/video sync is mixed, so test the unit against your own switcher before a live date.

Best for: A solo operator or small crew who wants an affordable, portable HDMI to NDI|HX3 encoder that can also drive a monitor as a decoder.

The ZowieBox earns the top spot through breadth rather than raw specs. It combines native NDI|HX3, three power paths (PoE, USB-C and a DC feed), PTZ control over VISCA and a tally light in a body that weighs under 6 oz. No other unit here packs that much into so little space for broadcast work on location.

Setup is simple, and the value is strong for what it does. The trade-off is quality ceiling: NDI|HX3 is compressed, so it will not match the SZXLCOM HDMI Full NDI Encoder or the Magewell Pro Convert HDMI 4K Plus where bitrate is the priority.

It is the wrong choice if the pipeline needs full NDI or if you want a screen for on-device control. In the second case the Zowietek ZowieBox Pro 4K60 adds a touchscreen and 4K60 support. Buyers who need SDI input should look at the Magewell Pro Convert SDI TX instead, because this unit takes HDMI only.

2. SZXLCOM HDMI Full NDI Encoder: Best Full NDI HDMI Encoder for Low Latency Production

• NDI Support: Full NDI, not NDI HX
• Resolution: 1080p at 60 fps
• Latency: End-to-end under 60 ms (manufacturer figure)
• Power: PoE or USB-C, 12 V adapter included
• Extras: HDMI loop out, PTZ control, tally, audio embed and de-embed, LCD

Pros:

• Full NDI means a higher bitrate and cleaner image than any HX encoder on this list at the same resolution.
• Web UI switching turns the same box into an NDI to HDMI decoder.
• PoE gives single-cable installation, with USB-C as a backup power option.
• The HDMI loop out, tally light and LCD cover local monitoring without extra hardware.

Cons:

• Resolution tops out at 1080p60, so it cannot take 4K sources.
• It is a lesser-known brand, and the product data includes no buyer feedback to confirm long-term reliability.
• Warranty is one year, half the term Magewell gives on its products.

Best for: Studios running a 1080p full NDI pipeline that want a low-latency HDMI encoder and decoder in one unit.

What sets this unit apart is that it offers full NDI at all. Most small encoders use HX because it is cheaper on bandwidth, but full NDI keeps more detail and cuts latency, and the stated figure of under 60 ms suits live switching. The Zowietek ZowieBox HDMI NDI is smaller and more flexible on streaming protocols, but it cannot match this encode quality.

The unit is also a hardware encoder and decoder in one body, with audio embedding on both sides. Because full NDI uses much more network capacity, plan for a gigabit switch with headroom if you run several of these on one network.

Skip it if you need 4K. The Magewell Pro Convert HDMI 4K Plus accepts 4096×2160 at 60 fps and is the better fit for high resolution work. It is also a poor fit if you need RTMP or SRT output, which the Magewell Ultra Encode models handle.

3. Magewell Pro Convert HDMI 4K Plus: Best 4K60 HDMI to NDI Encoder for Studio Installs

• Input: HDMI up to 4096×2160 at 60 fps (4:4:4 8-bit)
• Output: NDI high bandwidth up to 4096×2160 at 60 fps (4:2:2 8-bit)
• Network: RJ45 gigabit Ethernet
• Power: PoE or USB power adapter
• Warranty: 2 years

Pros:

• It handles 4K60 on both input and output, the highest resolution among the dedicated NDI converters here.
• Built-in processing covers de-interlacing, cropping, scaling, aspect ratio and color format conversion.
• The integrated HDMI loop-through allows local monitoring while the same signal goes onto the network.
• It is built for 24/7 operation in a rugged metal housing, and works with OBS Studio, vMix and Wirecast on Windows, macOS and Linux.

Cons:

• It is a premium-priced unit and does only one job: HDMI to NDI.
• There are no streaming protocols such as RTMP or SRT, so it cannot feed a platform directly.
• It is larger than the Zowietek units, which matters in tight camera rigs.

Best for: Production studios, classrooms and venues that need a permanently installed 4K60 HDMI to NDI converter.

The Pro Convert HDMI 4K Plus is a pure converter, and that focus is its strength. Magewell supports resolutions up to 4096×2160 at 60 fps with chroma conversion on board, which makes it the safer choice for feeds heading to a switcher that expects clean full-bandwidth streams. Against the SZXLCOM HDMI Full NDI Encoder, it trades some portability for twice the frame rate at 4K and a two-year warranty.

It can control PTZ cameras and pass tally data through supported interfaces. That makes it a natural fit for multi-camera rooms where each camera gets its own converter and a PoE switch supplies the power.

Choose a different model if you want to stream to platforms or record. The Magewell Ultra Encode HDMI Plus adds RTMP, SRT and onboard recording but caps at 4K30 and uses NDI|HX. If your source is SDI, the Magewell Pro Convert SDI TX is the matching converter.

4. WayPonDEV Link Pi ENC5-V2: Best 5 Port HDMI Encoder for Multi-Source Streaming

• Inputs: 5 HDMI 1.4 ports, up to 4K30 input
• Memory: 4GB DDR4 RAM, 8GB eMMC
• Protocols: NDI, SRT, HX, RTMP, RTSP, HLS, UDP, ONVIF
• Power: 12 V DC, 24 W nominal
• Size: 250 x 130 x 30 mm

Pros:

• Five HDMI inputs in one chassis replace several single-channel encoders for multi-camera events.
• The protocol list is broad, covering RTSP, RTMP, HLS, UDP, ONVIF, unicast and multicast.
• It also decodes and supports mixing and director functions, plus tally control.
• It supports an SDK and a rich API, which suits custom automation.

Cons:

• Buyers report that NDI use beyond a short trial needs a separate license, which is not obvious from the product description.
• The unit ships with a preset IP address that does not fit most default subnets, and fixing it means using a reset pinhole.
• Some users find colors slightly washed, though firmware updates reportedly improve this.

Best for: Event and house of worship teams that want several HDMI feeds encoded centrally and are comfortable with some network configuration.

The ENC5-V2 is for anyone who counts inputs before anything else. Five HDMI ports and 4GB of RAM give it the muscle to run several streams at once, which neither Zowietek model can match. For teams planning an even bigger rack, a 16 channel encoder is the next step up in density.

It is less polished than the Magewell range. Setup needs more network knowledge, and the NDI license point means the effective cost can be higher than it first looks. Input is limited to HDMI 1.4, so 4K is 30 fps at most.

Pick the Magewell Ultra Encode AIO if you need SDI as well as HDMI, or the Zowietek ZowieBox HDMI NDI if you only need one source and want a far simpler setup.

5. TBS TBS2602 SDI Encoder: Best NDI HX2 SDI Encoder for Basic IP Distribution

• NDI Support: Native NDI|HX2
• Input: 1 SDI channel
• Codecs: H.265 and H.264 High Profile, dual stream H.264
• Outputs: Dual stream RJ45
• Power: 12 V, 2 A, 0.44 kg

Pros:

• It brings SDI sources onto an NDI|HX2 network with a single, simple device.
• Both H.265 and H.264 are supported, with a dual stream H.264 output for a main and a lower-rate feed.
• Protocols include HTTP, HLS, RTSP, RTMP, RTP and UDP in addition to NDI.
• The use cases span IPTV, digital signage, campus broadcast and recording systems.

Cons:

• It has no PoE in the specifications, so every unit needs its own 12 V supply.
• There is no loop-through, tally or PTZ control listed.
• Specs are sparse, and the resolution limits are not specified.

Best for: Schools, hotels and small venues that need to push one SDI source onto an IP network without paying for a premium converter.

Check current price on Amazon →

This is a straightforward SDI encoder with NDI|HX2 added. It does less than the Magewell Pro Convert SDI TX, which offers 16 channel embedded audio, PTZ control and PoE, but it covers a wider list of streaming protocols. Its roots are in distribution work, so it makes sense where the end goal is an IP video system. Anyone building that kind of setup might also look at a 4 channel IPTV encoder for multi-source distribution.

For serious live production it is the wrong tool. Without PoE, tally or listed resolution limits, the Magewell Ultra Encode SDI Plus is the better option for SDI work that also needs streaming and recording.

6. Zowietek ZowieBox Pro 4K60: Best Touchscreen NDI 6 Encoder for AI Tracking and Recording

• NDI Support: NDI 6 with NDI|HX3 and HX2 encode and decode (no Full NDI)
• Resolution: Up to 4K60 HDMI input and output
• Display: 3.42 inch TFT touchscreen
• Power: USB-C, 12 V DC or PoE, 10 W without DC out
• Recording: USB-A drive, TF card or NAS in MP4, MOV or TS

Pros:

• A touchscreen and a tally light allow direct control without a computer.
• It supports 4K60 with a zero-latency HDMI loop-out and dual-stream encoding (4K60 main plus a 720p sub-stream).
• Built-in AI edge processing provides single and multi-target tracking on supported PTZ cameras.
• Audio is strong: a mic input, line-in, headphone output and up to 8 channels, plus simultaneous recording and streaming.

Cons:

• It does not support Full NDI or NDI|HB, and cannot encode and decode at the same time.
• At 6.9 oz it is heavier than the original ZowieBox, and it is also the more expensive of the two.
• AI tracking works best with Zowietek's own PTZ cameras, so third-party camera users may see fewer benefits.

Best for: Houses of worship, lecture capture and event crews who want a self-contained encoder with a screen, recording and PTZ tracking.

On features alone, the ZowieBox Pro is the most capable Zowietek product, and it rivals the Magewell Ultra Encode line for streaming and recording. It sits at sixth because it is a newer, more expensive step up from the Zowietek ZowieBox HDMI NDI, and many broadcast jobs do not need the extra functions.

NDI latency is quoted at 2 to 3 frames, with an NDI Bridge for remote production and an open API for automation. Its multi-destination RTMP and SRT streaming makes it a solid choice when the same feed must reach NDI and several platforms at once.

If you need Full NDI, it is the wrong box: use the SZXLCOM HDMI Full NDI Encoder or the Magewell Pro Convert HDMI 4K Plus. If you need SDI, the Magewell Ultra Encode AIO is the nearest alternative.

7. Magewell Ultra Encode AIO: Best Dual HDMI and SDI Encoder for Multi-Destination Streaming

• Inputs: HDMI up to 4096x2160p60, SDI up to 4096x2160p30
• Codecs: H.264 or HEVC
• Streaming: Up to six destinations (RTMP, RTMPS, SRT, NDI|HX2/HX3, HLS, TS over UDP/RTP)
• Network: PoE, Wi-Fi, 4G USB modem support
• Form Factor: Rack mount, about 3.6 lb, 2 year warranty

Pros:

• It accepts either HDMI or SDI, or both together in picture-in-picture or side-by-side layouts.
• Up to eight text, image or clock overlays are available for branded output.
• It records to SD card, USB or network drives while streaming, with loop and scheduled recording.
• The front-panel LCD, web UI and API allow flexible control in a rack.

Cons:

• At 3.6 lb and with rack ears, it is bulky next to the compact Zowietek units.
• SDI input is limited to 4K30, while only HDMI reaches 60 fps.
• It is premium-priced, and NDI is HX only.

Best for: Streaming teams who need a rack-based hardware encoder that combines HDMI and SDI sources and sends them to several platforms at once.

The AIO is the all-in-one of the Magewell family. Dual-input mixing means one device can handle a camera and a presentation source without a separate switcher, which neither the Magewell Ultra Encode HDMI Plus nor the Magewell Ultra Encode SDI Plus can do.

Its NDI|HX2 and HX3 output is just one of six possible destinations, so it fits workflows in which NDI is one feed among many. If NDI is the only goal, the Magewell Pro Convert HDMI 4K Plus is more focused and cleaner in bandwidth terms.

8. Magewell Ultra Encode HDMI Plus: Best Compact PoE HDMI Encoder for Streaming and Recording

• Input: HDMI up to 4096x2160p30 with loop-through
• Streaming: RTMP, RTMPS, SRT, NDI|HX, HLS, TS over UDP/RTP
• Storage: 128 GB internal, plus USB and network recording
• Network: Gigabit Ethernet with PoE, Wi-Fi 802.11 a/b/g/n/ac
• Size: 4.2 x 4.2 x 1 inches

Pros:

• The 4.2 inch square body is small enough to sit behind a display or on a camera cage.
• 128 GB of internal storage lets it record without any external media.
• PoE, Wi-Fi and support for 4G/5G USB modems cover fixed and mobile deployments.
• Overlays, scaling, cropping and de-interlacing handle branding and format fixes on board.

Cons:

• Encoding is limited to 4K30, below the 4K60 of the Pro Convert HDMI 4K Plus.
• NDI is HX only, so it is not a high-bandwidth NDI device.
• The data lists no tally or PTZ control, unlike the Pro Convert models.

Best for: Remote and mobile crews who want a small HDMI encoder that streams to platforms, records locally and also offers NDI|HX.

This is a smaller, simpler sibling to the Magewell Ultra Encode AIO. It drops the SDI input and the mixing, and in return gets a body a fraction of the size with PoE and built-in storage. Compared with the Zowietek ZowieBox HDMI NDI, it has more recording capability and a longer warranty, while the Zowietek has tally, PTZ control and decoding.

It is a good fit for a camera position where the job is to deliver a platform stream and an NDI|HX feed from one source. For a strict NDI-only studio install, the dedicated converters are the better pick.

9. Magewell Pro Convert SDI TX: Best SDI to NDI Converter for 24/7 Broadcast Rooms

• Input: SD, HD and 3G-SDI, up to 2048×1080 at 60 fps
• Output: NDI high bandwidth
• Audio: Up to 16 channels of embedded audio
• Network: Gigabit Ethernet with multicast and VLAN support
• Design: Fanless, PoE or USB power, 2 year warranty

Pros:

• It converts SDI to NDI high bandwidth, so quality is closer to the full NDI end of the market than the HX models.
• 16 embedded audio channels stay in sync with the video.
• PTZ control works through NDI or VISCA over IP, with tally support.
• Fanless construction is made for continuous operation in broadcast, education and worship spaces.

Cons:

• Maximum resolution is 2048×1080, so 4K SDI sources are not supported.
• It does not stream to platforms or record, since it only converts to NDI.
• Few specs beyond the feature list are available, and no dimensions or weight are listed.

Best for: Broadcast rooms with SDI cameras or routers that need clean, dependable NDI conversion on a managed network.

For SDI work this is the equivalent of the Magewell Pro Convert HDMI 4K Plus: a single-purpose converter with processing, PoE and a strong reputation for continuous running. Its high bandwidth output beats the NDI|HX2 on the TBS TBS2602 SDI Encoder, and the 16 channel audio and PTZ support are far beyond it.

Note that SDI runs over coax, and it is good practice to keep cable runs short and well terminated, with fiber or an optical cable for longer distances. It is not the right choice for streaming to platforms or recording. For that, the Magewell Ultra Encode SDI Plus is the matching device.

10. Magewell Ultra Encode SDI Plus: Best Compact SDI Encoder for Streaming and Local Recording

• Input: 6G-SDI up to 4096x2160p30
• Codecs: H.264 or H.265 (HEVC)
• Streaming: RTMP, RTMPS, SRT, NDI|HX, HLS, TS over UDP/RTP
• Storage: 128 GB internal, USB and network recording
• Network: Gigabit Ethernet with PoE, Wi-Fi 802.11 a/b/g/n/ac

Pros:

• It is the compact SDI answer for 4K30 sources, in a 4.2 inch square body.
• Streaming to multiple destinations runs alongside local recording on 128 GB of internal storage.
• The kit includes a power adapter, USB cable, Wi-Fi antenna and a T-bracket for mounting.
• Overlays and video processing support branded output without extra gear.

Cons:

• NDI is HX only, so it cannot match the Pro Convert SDI TX for quality.
• There is no HDMI input, so it does not suit mixed-source setups.
• No tally or PTZ control appears in the specifications.

Best for: Crews with SDI cameras who need to deliver platform streams, local recordings and an NDI|HX feed from one small unit.

The SDI Plus is the mirror of the Magewell Ultra Encode HDMI Plus, with the same storage, network and protocol options on an SDI input. It supports 6G-SDI connectivity and gives HEVC encoding for bandwidth-efficient contribution links.

It ranks last because most of this list is better aimed at NDI as a primary goal. Choose it for streaming first and NDI second. If NDI quality matters most for SDI sources, the Magewell Pro Convert SDI TX is the better pick, and if you need both input types, the Magewell Ultra Encode AIO covers them.

Buyer's Guide: How to Choose the Right NDI Encoder

The core trade-off is between NDI quality and everything else. Full NDI and NDI high bandwidth look better and respond faster, but they need serious network capacity. HX encoders are smaller and cheaper on bandwidth, and they usually add streaming and recording features, at the cost of some image fidelity.

Before choosing, check these project details:

• Source connector: HDMI sources suit the Zowietek and SZXLCOM units, while SDI sources need the Magewell SDI models or the TBS.
• NDI type: Full NDI or high bandwidth for studio quality, HX for efficient transport across weaker networks.
• Resolution and frame rate: 1080p60 is enough for most shows, but 4K60 needs the Pro Convert HDMI 4K Plus or the ZowieBox Pro.
• Power: PoE removes outlets from camera positions, and most units here support it.
• Extra jobs: Streaming to platforms, recording and PTZ control each narrow the shortlist.

NDI Flavor: Full, High Bandwidth and HX

Full NDI is offered by the SZXLCOM HDMI Full NDI Encoder, which claims latency under 60 ms. The Magewell Pro Convert HDMI 4K Plus and Magewell Pro Convert SDI TX produce NDI high bandwidth streams, which sit at the same quality tier for studio work and need a gigabit network built for them.

HX variants are used by the Zowietek ZowieBox HDMI NDI, ZowieBox Pro 4K60, TBS TBS2602, and all three Magewell Ultra Encode models. They compress with H.264 or H.265, which keeps bandwidth low and allows Wi-Fi or remote links, but they add a little latency and some softness on fast motion.

Input Type and Resolution

HDMI is common on cameras, consoles and laptops, and it is the input on the Zowietek, SZXLCOM and WayPonDEV units. The WayPonDEV Link Pi ENC5-V2 has five HDMI ports, but they are HDMI 1.4 with 4K30 at most. For 4K60, look at the Pro Convert HDMI 4K Plus, the ZowieBox Pro or the Ultra Encode AIO (HDMI only).

SDI is the professional standard for long cable runs and locking connectors. The Magewell Pro Convert SDI TX supports up to 2048×1080 at 60 fps, while the Magewell Ultra Encode SDI Plus supports 4K30. The Magewell Ultra Encode AIO is the only unit here that takes both.

Power and Network Setup

PoE is the most practical feature for broadcast installs. It means one cable for power and data, and the Zowietek, SZXLCOM and Magewell units all support it. The TBS TBS2602 and WayPonDEV Link Pi ENC5-V2 rely on a 12 V supply, which is easier to work with in a rack than at a remote camera.

Network design matters as much as the encoder. Full NDI and high bandwidth need a managed gigabit switch with multicast and VLAN support, which the Pro Convert SDI TX explicitly handles. Wi-Fi on the Ultra Encode line is convenient for backup paths, but it is not a replacement for wired NDI.

Streaming, Recording and Control

If the feed must also reach YouTube or another platform, choose an encoder with RTMP and SRT. The Zowietek ZowieBox Pro 4K60 and the Magewell Ultra Encode AIO can stream to multiple destinations at once, while the pure converters cannot stream to platforms.

Recording and control are the other differentiators. The Ultra Encode HDMI Plus and SDI Plus have 128 GB of internal storage, and the ZowieBox Pro records to USB, TF card or NAS. PTZ control and tally are provided by the Zowietek units, the SZXLCOM and the Magewell Pro Convert models.

Frequently Asked Questions About NDI Encoders for Broadcast

What Is the Difference Between Full NDI and NDI HX?

Full NDI uses a high-bandwidth, low-latency codec that preserves more detail, as on the SZXLCOM HDMI Full NDI Encoder. NDI HX uses H.264 or H.265 compression to cut bandwidth, as on the Zowietek ZowieBox HDMI NDI. HX suits constrained networks, while full or high bandwidth NDI suits wired studios.

Which NDI Encoder Is Best for 4K Video?

The Magewell Pro Convert HDMI 4K Plus accepts 4096×2160 at 60 fps and outputs NDI high bandwidth at the same resolution. The Zowietek ZowieBox Pro 4K60 also handles 4K60 HDMI using NDI|HX3. For 4K SDI sources, the Magewell Ultra Encode SDI Plus supports up to 4096×2160 at 30 fps.

Do I Need an SDI or HDMI NDI Encoder?

Match the encoder to the output of your cameras and switchers. HDMI suits the Zowietek, SZXLCOM and Magewell Pro Convert HDMI 4K Plus. SDI sources should use the Magewell Pro Convert SDI TX or the TBS TBS2602, and the Magewell Ultra Encode AIO takes both.

Can an NDI Encoder Also Stream to YouTube or Twitch?

Some can. The Magewell Ultra Encode AIO, HDMI Plus and SDI Plus support RTMP, RTMPS and SRT alongside NDI, as does the Zowietek ZowieBox Pro 4K60. The Magewell Pro Convert models only convert to NDI, so they need a computer or switcher to send the feed to a platform.

Does an NDI Encoder Need PoE?

It is not required, but it is very useful for ceiling or remote camera positions. The Zowietek ZowieBox HDMI NDI, SZXLCOM and Magewell models all support it, so a single Ethernet cable can carry power and video. The WayPonDEV Link Pi ENC5-V2 and TBS TBS2602 need a 12 V supply.

Can One ZowieBox Encode and Decode at the Same Time?

No. Both the Zowietek ZowieBox HDMI NDI and the ZowieBox Pro 4K60 run in one mode at a time. For a two-way link, use two units, with one as the encoder and the other as the decoder.

Final Verdict: Which NDI Encoder Should You Buy?

Best NDI Encoders for Broadcast for most small crews and studios start with Zowietek ZowieBox HDMI NDI: it is a 5.9 oz unit with native NDI|HX3, encoder and decoder modes, SRT and RTMP output, and PoE, USB-C or DC power. Its main weakness is that it supports HX only and cannot encode and decode simultaneously, with mixed feedback on reliability.

For alternatives by use case, the SZXLCOM HDMI Full NDI Encoder is the pick for 1080p60 full NDI with low latency. The Magewell Pro Convert HDMI 4K Plus is the choice for 4K60 HDMI in permanent installs, and the Magewell Pro Convert SDI TX does the same job for SDI. The Zowietek ZowieBox Pro 4K60 suits crews who want a touchscreen, recording and AI tracking.

The specialist picks are narrower. The WayPonDEV Link Pi ENC5-V2 handles five HDMI feeds, the Magewell Ultra Encode AIO mixes HDMI and SDI for multi-destination streaming, and the Magewell Ultra Encode HDMI Plus and SDI Plus pair compact bodies with 128 GB of storage. The TBS TBS2602 is a simple SDI to NDI|HX2 route. If you are still undecided, pick by your source connector first, then by whether you need full NDI quality or streaming features.
