The Vseebox Elite Ultra features a 4K HDR10+ video capture module with an upper limit resolution of 4096×2160 and 120FPS. It is capable, however, of keeping a 93% color gamut ratio and a dynamic range of 14 stops under a lighting-poor environment (illuminance ≤5 lux). Its two HDMI 2.1 input ports allow for simultaneous acquisition of signals from two devices (with a lag of less than 0.5ms). Paired with the AI intelligent director system, it is able to create real-time multi-camera switching effects (with the switching speed as high as 16ms). For example, during the 2023 League of Legends World Championship live streaming, a production team used Vseebox Elite Ultra to implement automatic shot switching at a three times per second rate, while the audience interactive rate increased by 27%.
The cross-platform streaming function allows for simultaneous pushing of 4K streams to five places (e.g., YouTube, Twitch, and Bilibili) with a peak bitrate of 100Mbps. Moreover, the native bandwidth optimization algorithm is able to conserve network usage up to 40%. The figures tested in 2024 show that when Vseebox Elite Ultra is applied for 8-hour live streaming under a condition of 30Mbps uplink bandwidth, the frame loss rate can be as low as 0.03% (the standard in the industry is 0.15%). Its NDI|HX3 transmission protocol is capable of supporting 4:4:4 chromaticity sampling within a local area network at a managed delay of 30ms, three times that of the standard RTMP protocol. A specific live e-sports broadcasting team has thereby minimized the synchronism error between real-time event commentary and game images to ±50ms.
As far as audio processing is concerned, Vseebox Elite Ultra contains a 32-bit /384kHz audio acquisition board, which features a signal-to-noise ratio of 127dB. In combination with the AI noise reduction algorithm, it can attenuate the surrounding noise by 35dB. At the live broadcast of the 2024 Tokyo International Musical Instruments Show, users adopted Sennheiser MK4 microphones with the XLR interface, while the harmonic distortion ratio of the true human voice frequency response curve (20Hz-20kHz) was lower than 0.001%. The product can also perform surround sound mixing at 7.1 channels with ±3° positioning accuracy of the sound field, which is 60% higher than that of the previous generation product.
Excellent hardware scalability: Integrated dual PCIe 4.0 slots for the mounting of Blackmagic DeckLink 8K Pro capture cards, with 12G-SDI input (HLG and Dolby Vision compatible). For storage, it has an 8TB NVMe SSD (read/write speed of 7GB/s) and two hot-swappable hard disk bays, which can record 8K RAW video continuously for 48 hours (1.2Gbps bitrate). A documentary team operated continuously for 72 hours using the Vseebox Elite Ultra in the Amazon rainforest. The surface temperature of the device was constantly less than 45℃ (ambient temperature 38℃), and the power consumption of the heat dissipation system was only 18W.
The intelligent assist functions are: AI virtual host creation (supporting 3D digital human real-time drive, lip sync error < 5ms), multi-language real-time subtitles (recognition accuracy 98.7%, supporting 112 languages), and intelligent camera movement algorithm (preset 200 movie-level transition effects). The instance of a specific enterprise press conference in 2024 shows that following the utilization of the auto-composition capability of Vseebox Elite Ultra, the accuracy of facial tracking of the speaker was up to 99.2%, and the response time of picture cropping was 15 times quicker compared to manual. The device also features satellite-level packet loss resilience via the SRT protocol (maintaining 4K picture quality at 30% packet loss). During its live streaming of the 2023 Arctic scientific expedition, it delivered successfully 4K60P signals over a distance of 12,000 kilometers with a latency as low as 380ms.
In software ecosystem language, the Vseebox Elite Ultra comes equipped with the Vseestream Pro package containing the HEVC encoder (which offers 50% more efficient compression than H.264), a multi-screen monitoring template (for display on one screen of 16 signals), and a cloud collaboration module (that allows synchronization of up to 10 editing terminals). Its response time of the remote control API of below 10ms and support for Tesla’s in-vehicle live broadcasting system have attained real-time superposition of image-in-picture automobile driving data (position refresh rate 100Hz). In the 2024 CES Innovation Awards selection, Vseebox Elite Ultra, based on the aforementioned functional system, ranked first among professional live broadcasting devices with a perfect score of 97.3 points.
