Vela G Technical Datasheet

Feature Overview
Vela G is a highly integrated, multi-functional mini appliance designed for encoding, decoding, recording, playback, and live streaming, with Genlock input. It serves as a compact all-in-one solution for professional video workflows. Vela G features one 12G-SDI input and output for UHD baseband signals, along with one HDMI 4K input/output interface. It supports encoding, decoding, recording, live streaming, optical output, and audio embedding/de-embedding for a full range of mainstream international IP streaming protocols. Integrated with remote scheduling and multiple other functions, the device enables concurrent operation of multiple features. Users can flexibly combine and run different functional modules simultaneously according to on-site requirements. Fully compatible with the NDI ecosystem, Vela G supports encoding and decoding across the complete NDI protocol suite, including High Bandwidth NDI (NDI\|HB), NDI HX2 and NDI HX3 for both high and low bandwidth scenarios, as well as the latest features of NDI 6.3. Equipped with native encoding capabilities for mainstream streaming protocols such as H.264, H.265, SRT, RTMP, RTSP and TS UDP, Vela G delivers low-latency one-click live streaming and push streaming with great ease.

Features
1.Vela G supports simultaneous NDI HX2/HX3 encode/decode, recording, streaming, and optical output via a single 12G-SDI or HDMI 4K input. 2.While performing 4K 50 recording, Vela G concurrently supports NDI HX2/HX3 encoding and decoding (return feed). 3.When encoding NDI HX2/HX3 in 4K 30 and lower resolutions, Vela G enables live streaming and recording over SRT, RTMP, RTSP, TS UDP and other protocols. 4.Vela G supports video playback from local storage with customizable loop modes, and auto-resume playback after power cycle. Notes: 1.When encoding or decoding with High Bandwidth NDI (NDI\|HB), simultaneous recording and live streaming are not supported. 2.Recording is unavailable for internal live streaming, and only supported for external live streaming.

Hard Disk Compatibility	Storage Configuration & Drive Selection：The Vela device uses one M.2 drive for local storage, which need to be purchased separately by users. For stable recording performance, it is recommended to select high-performance NVMe SSDs that have passed compatibility tests as listed in the table below. Recording Mechanism & Capacity Planning：Vela supports two container formats: MP4 and MOV. Notably, while recording the main MP4/MOV file, the system automatically generates a TS stream file of the same size for backup. Note：Due to the dual-recording mechanism, the actual storage consumption is approximately twice that of a single file. Please reserve sufficient spare space when estimating hard drive capacity.
