When we first unboxed the YoloLiv YoloBox Ultra, we expected another compact all‑in‑one streamer – what we got felt more like a broadcast control room in tablet form. The Ultra is billed as the ultimate horizontal/vertical NDI live streaming equipment, and after spending focused time with it as a switcher, monitor, encoder and recorder, we can say it truly aims to consolidate a lot of production muscle into a single 4K device. From multi‑destination streaming to ISO recordings and cellular bonding,it’s designed for creators who need professional features without hauling a truckload of gear.
YoloLiv - a lively team out of Hangzhou - has clearly built this around their mission to “make pro video accessible.” The YoloBox Ultra picks up that thread: intuitive enough for a novice to start a clean stream, yet deep enough for us to route NDI sources, enable SRT, and tweak ISO outputs for post. We put it through mixed scenarios – event livestreams, vertical social feeds, and multi‑camera set ups – and appreciated the adaptability of horizontal and vertical streaming modes (note: not simultaneously), dual 4G dongle support, Wi‑fi/Ethernet, and optional five‑link cellular bonding for challenging networks.
This review will walk through what worked, where the Ultra surprised us, and the tradeoffs you should weigh if you’re considering it for streaming to Facebook, YouTube, Instagram, TikTok or RTMPS endpoints. We’ll cover setup, live performance, connectivity options, recording capabilities, and how the YoloBox Ultra fits into real‑world productions – from weddings and sports to church services and social‑first broadcasts.

Detailed Insights from Our testing and Practical Recommendations for Streamers and Creators
In our hands-on testing we found the unit delivers the kind of reliable, pro-level output YoloLiv promises: true 4K switching, monitoring, encoding and recording in a single package. The built-in flexibility – 4G LTE, Wi‑Fi, Ethernet and support for dual 4G dongles – meant we could keep a steady stream during both staged indoor shoots and chaotic outdoor events. Highlights from real-world sessions include:
- Sports and live events: clean motion handling and low-latency switching when paired with SRT/NDI (note: these integrations may incur extra fees).
- Weddings and corporate streams: ISO recordings gave us discrete feeds for polished post-production edits.
- Remote field work: cellular bonding (up to five connections) kept streams stable in areas with flaky single-carrier coverage.
- Multi-platform output: use Live Streaming Mode for up to three horizontal destinations or Vertical Mode for two vertical destinations – just remember both modes cannot stream simultaneously.
We appreciated the product vision – make pro video accessible – because the hardware felt designed to let creators scale from one-person setups to multi-camera teams without a steep learning curve.
For creators looking to get the moast from our testing: prioritize ISO recordings for any session you plan to edit,and build a network stack that combines Ethernet + Wi‑Fi + at least one USB modem for best resilience. Below is a quick reference we used when preparing shows:
| Scenario | Recommended Mode | Network Setup |
|---|---|---|
| Studio interview | Live (horizontal) | Ethernet + Wi‑Fi |
| Outdoor sports | Live (horizontal) | 2x USB modems + 4G LTE |
| Social Reels/TikTok | Vertical Mode | Wi‑Fi + 1 USB modem |
Practical tips: enable ISO at the start of every shoot, test SRT/NDI remote links prior to go-time if you plan remote production, and switch to bonding when single connections show packet loss. If you want a turnkey purchase after comparing setups, grab yours here: Buy on Amazon
Pros & Cons
We put the YoloBox Ultra through its paces and came away impressed by its ambition – a single device that aims to be a mobile studio. Below are the strengths and trade‑offs we noticed as we tested its vertical and horizontal workflows.

Pros – What we liked
- All‑in‑one production: We loved that the Ultra combines switching, monitoring, encoding and recording into one 4K device - it truly replaces several pieces of kit for mobile crews.
- Vertical & horizontal workflows: The dedicated vertical mode is a real advantage if you produce for Instagram or TikTok; switching orientation is simple and purpose‑built.
- Robust connectivity: With Wi‑Fi, Ethernet, LTE and options for two USB modems, we found it resilient in mixed network conditions – and cellular bonding (when enabled) can keep streams stable in the field.
- ISO recording for post: Recording each input separately gives us creative control in post‑production, which is essential for event and multi‑camera shoots.
- YoloLiv ecosystem: Integration with YoloCast and other YoloLiv tools makes it easier for us to scale a workflow or add remote contributors.
Cons – Trade‑offs to consider
- No simultaneous vertical+horizontal streaming: If your production needs to push both formats at once, the Ultra’s mode separation is a limitation – you must choose one orientation per stream session.
- Extra costs for pro features: NDI, SRT and advanced cellular bonding aren’t always included – we had to factor in additional licensing or service fees to unlock full remote‑production capabilities.
- Heavy files & workflow demands: ISO and 4K recordings are fantastic, but they create big files and longer edit times.Our post workflow needed more storage and time planning.
- Learning curve: For absolute beginners, the depth of features can feel overwhelming. While the interface is accessible,mastering multi‑destination routing and bonding takes practice.
- Destination limits: The ceiling of three horizontal or two vertical destinations per mode may be restrictive for users who need many simultaneous outputs without using additional encoders or services.
In short, we see the YoloBox Ultra as a potent, portable studio that trades some simplicity for professional flexibility.For creators and small production teams who value all‑in‑one capability and are cozy with optional add‑ons and post‑production workflows, it’s a strong contender. For those who need always‑on simultaneous vertical+horizontal distribution or want every pro feature included out of the box, there are important caveats to weigh.
