Datavideo NVS-35 Overview

Simultaneously stream up to 1080p60 H.264/AVC video to two web destinations such as Facebook, YouTube, Twitch, Amazon Web Services, and others with the H.264 Dual Streaming Encoder/Recorder from DataVideo. The encoder has one HDMI input and one 3G-SDI input with a maximum resolution of 1080p60, and it can input analog audio for embedding via its RCA and 3-pin XLR inputs. It is capable of two simultaneous streams via its Ethernet port using common protocols such as RTMP/RTSP and SRT in H.264/AVC encoding format.

You can simultaneously record your stream to an SD card via its built-in card slot for editing and archiving. It is also compatible with dvCloud, an optional subscription service that allows you to manage your streams and record H.264 programs over the Internet. It allows you to encode in a variety of resolutions from 128 x 128 to 1920 x 1080, and it also supports vertical streaming to accommodate smartphone streaming clients.

Simultaneous Streaming and Recording
Simultaneous live streaming and recording in H.264 format is supported, suitable for a variety of applications.
Multiple Input Configurations
HDMI and SDI video input is supported; XLR and RCA audio inputs are provided.
Direct Recording to SD Card
Support for FAT32, exFAT, and NTFS file systems and continuous recording without file size limitation.
Dual Streaming
Simultaneously live streaming to two platforms such as YouTube and Facebook.
Vertical Screen Streaming
Viewers using a smartphone to watch the video stream may prefer vertical orientation. The NVS-35 offers a vertical screen streaming function and you can easily create a vertical-oriented video with a few basic settings.
Selectable Audio Output
Optional embedded audio/external audio/mixed audio with wide compatibility.
SRT Streaming Protocol
Streaming RTMP over unreliable, low-bandwidth networks can cause issues. With dvCloud, you can now replace the RTMP protocol with SRT, which will fix most streaming issues you may have. SRT is better than RTMP because it handles problematic networks more efficiently.
Workflow with all Datavideo Products
Datavideo's wide range of encoders, cameras, and hand-carry switchers are fully supported by SRT and dvCloud. Datavideo encoders and dvCloud provide reliable streams over unreliable networks. By using a Datavideo encoder and dvCloud together, you can utilize SRT (instead of RTMP) on the initial problematic connection or "First Mile." After your video stream reaches dvCloud, you can depend on dvCloud's reliable, high-bandwidth network to deliver the stream to your favorite destinations, like Facebook and YouTube.
Compatible with dvCloud
Get the most out of your streaming hardware using dvCloud. The NVS-35 is seamlessly compatible with Datavideo's dvCloud service. This subscription service give you the possibility of sending your stream to multiple destinations at the same time without having to have multiple hardware encoders. You can also record your production on the dvCloud platform in H.264 format. After recording, you can directly use this recording to upload it to your favorite content platform.

Datavideo NVS-35 Reviews

Configuration Was Difficult

By James
Rated 2 out of 5
Date: 2025-04-02

After much trial and error, I was finally able to get the device to connect to my destination, only to have it fail to connect when coming down to the wire at production time. The web interface fails to connect reliably and the login screen doesn’t always appear when the user is logged out. As a highly-experienced user, I was frustrated time and again; I can’t expect my low-tech video operators to deal with this on a weekly basis.

The Datavideo H.264 Dual Streaming Encoder/Recorder has no recording with the USB, it is for Firmware updates only. The SD card Does not need to be UHS-II.
