Best GPU Servers for Live Streaming on YouTube with OBS Studio

Introduction

OBS Studio is a free and open-source software for video recording and live streaming. OBS Studio allows users to capture and mix multiple video sources, including webcams, game footage, browser windows, and more, into a single output stream that can be recorded or broadcast live to a variety of platforms, such as YouTube, Twitch, and Facebook. It is a popular tool for content creators, streamers, and gamers.

When it comes to live streaming on YouTube with OBS Studio, a powerful GPU server is essential for handling the demands of high-quality video encoding and transcoding. This is because video encoding and transcoding require a lot of processing power, and a GPU can significantly speed up these processes compared to using a CPU alone.

GPUMart offers a variety of GPU hosting options, including dedicated servers, virtual private servers, and cloud-based solutions. Their servers are equipped with powerful NVIDIA GPUs, which are commonly used for machine learning and other high-performance computing applications. GPUMart is known for its high-quality hosting services and excellent customer support.

Install and Configure OBS Studio

Download and Install OBS Studio
We use the most cost-effective Express GPU Server with Quadro P620 for our streaming test. First visit the OBS Studio official website to download and install the software, Windows system is recommended. A screenshot of the installation is shown in the figure below.

OBS Settings

Choosing the right OBS settings can make a huge difference in the quality of your recording. If your settings are too low, your video may be blurry, pixelated, or choppy. On the other hand, if your settings are too high, your video may be too large, take up too much space, or be difficult to upload and share. Finding the right balance is key.

Auto-Configuration Wizard
If you're new to OBS or just want to get started as quickly as possible, follow the steps in the Auto-Configuration Wizard. This wizard will automatically test your system and attempt to find settings that your PC can handle. This includes streaming or recording, resolution, bitrate, encoder, streaming provider and more. You can always modify the settings manually later.

Bitrate and Internet Speed
As you manipulate your bitrate settings, it is essential to consider your internet connection. Your internet speed must be at least double your OBS bitrate if you want to produce a high-quality stream. Otherwise, you’ll run into buffering issues. You can search “internet speed test” on Google and click “RUN SPEED TEST” to test how fast your internet is.

Youtube Bitrate Recommendation
Live Streaming Bitrate Calculator is a tool that helps you calculate the recommended and maximum bitrate for your Live Stream in order to make sure that your viewers can watch your stream without buffering or lag. Using our bitrate calculator you can get the accurate video bitrate and audio bitrate required for live streaming and video hosting.

OBS Studio Live Streaming Test Report

We used the express GPU server with Quadro P620 provided by GPUMart to conduct live streaming tests for different resolutions, 1080p, 1440p and 4k.We use a 4K Video file for testing, and the details of the file are as follows. Attached download from here.
4K file details

Test 1 - 1080P 60 FPS 10000 Kbps Live Streaming

1. First set the Media Source, as shown in the figure below, click Media Source.
Bind Youtube Streaming Service
2.Select a local 4k video file, remember to check Use hardware decoding when available.
select media file
3.Open the Settings interface, modify the Streaming Video Bitrate under Output to 10000 Kbps, the Audio Bitrate to 160, the Encoder to Hardware (NVENC H.264), and the Encode Preset to P5: Slow (Good Quality).
