OBS Studio function introduction

Multi-source recording and live streaming‌

Supports window capture, game screen, camera, picture, text, browser and other video sources, and can record multiple sources at the same time.

Supports full-screen recording, area recording and window recording to meet the needs of different scenarios.

Supports RTMP streaming and can be pushed to mainstream live broadcast platforms such as Twitch, YouTube, Douyu, Huya, and Bilibili.

‌Audio Mixing and Control‌

Built-in audio mixer supports multi-audio track recording, and can adjust the volume of microphone, system sound, background music, etc. separately.

Supports noise gate, noise suppression, gain and other filters to optimize sound quality.

Supports VST plug-ins to meet professional audio processing needs.

‌Multiple scene switching and transition‌

It supports unlimited scene switching, and can preset multiple scenes (such as game screens, camera screens, PPT demonstrations, etc.), and switch with one click during live broadcast.

Supports custom transition effects to make scene switching smoother.

‌Video Encoding and Output‌

Supports multiple video formats (MP4, FLV, MKV, etc.) and encoding methods (H.264, H.265).

The resolution, frame rate, and bit rate can be customized to meet different definition requirements.

Supports hardware accelerated encoding (NVENC, AMD VCE) to reduce CPU pressure and improve performance.

OBS Studio Features

High performance and low latency

Optimized rendering engine and hardware acceleration support (such as NVIDIA NVENC, AMD AMF, Intel Quick Sync) to keep CPU usage low even at 4K/120fps.

The built-in "low latency mode", combined with the adjustment of encoding parameters on the streaming side, can achieve second-level delay, which is suitable for highly interactive live broadcasts (such as games with microphones).

Highly customizable

Everything from interface layout to streaming parameters can be adjusted, supporting custom resolution, frame rate, bit rate, etc. to meet professional-level needs (such as broadcast-level live broadcast).

Interface elements can be dragged and dropped to freely adjust the position, size, and transparency of each source in the scene.

Cross-platform compatibility

Supports Windows, macOS and Linux systems, and experimentally supports the Windows on Arm (WoA) platform, expanding software compatibility.

How to use OBS Studio

Huajun Software Park provides you with how to use this software:

​ ​ 1. Open the main interface.

Scene: The scene is equivalent to PS drawing. The scene is the main picture and the source is the layer. You can set several different pictures.

Source: The meaning of layer is the source of the picture you want to show to the audience. Just right click on the source and add it.

​ ​ 1) Get the window: Add a single window for the audience to see.

​ ​ 2) Monitor acquisition: Single screen or multiple screens, select a display to show full screen or part of the screen to the audience (League of Legends selection)

​ ​ 3) Picture source: If you have your own logo or station logo or cute pictures, you can hang them up. If you don’t want the audience to watch your computer operations, you can delete the monitor and put the underlying picture as a desktop. This way you can live broadcast and do other things to prevent unintentional data leakage.

​ ​ 4) Slideshow: Add a variety of pictures by yourself and show them to the audience in the form of a slideshow.

5) Text source: Write some words or tips or advertisements for the audience

​ ​ 6) Video capture equipment:camera, capture card and other capture peripherals screen access port

​ ​ 7) Game source: Full-screen games must be broadcast live using a game source, otherwise the audience will see a black screen. Borderless or windowed full screen, you can directly add a window for live broadcast. (dota2, Hearthstone selection, League of Legends)

③Settings: Live broadcast program settings

④Start streaming: Start live broadcast

​ ​ ⑤Edit scene: Manually adjust the live broadcast screen, such as text and picture position adjustment or scaling.

⑥Start recording: Use OBS to record the screen.

⑦Global source: overall source, basically no need to set.

​ ​ ⑧Preview streaming: simulate the live broadcast screen without live broadcast, and can test whether frame skipping, code rate changes, screen adjustment and other data.

Note: For all games, the game source is selected first, the second is the monitor acquisition, and the third is the acquisition window.

PS: Two red bars, the left represents the microphone output volume, and the right represents the sound output volume. Click the red bar to adjust the output volume, and click the icon to directly mute the device.

2. Encoding settings such as maximum bit rate

PS: The higher the final number, the better. Generally speaking, the bit rate settings are adjusted according to the game. The following is an introduction to the optimal bit rate:

Other competitive games 1800kb/s (such as League of Legends, DOTA, etc.)

Shooting and stand-alone games 2000kb/s (such as: CSGO, World of Tanks, etc.)

Nostalgic memory: 1500kb/s (such as War of the Three Kingdoms, MC, etc.)

Game screening room: 1500kb/s

3. Broadcast settings

​​ 4. The FMS URL streaming code acquisition address is as follows: (Fill in the corresponding top and bottom and copy in)

5. Resolution, frame rate (fps) and other settings

​ ​​Try to use 720P or lower for notebooks. Please choose 720P for desktop I3 and I5. For I5 overclocking, the I7 series can be increased to 1080P. AMD please test it yourself.

ps:

Recommended settings for each game:

Other competitive games 30FPS 1920X1080 (League of Legends, DOTA2, etc.)

Shooting and stand-alone games 30FPS 1920X1080 (CSGO and other shooting stand-alone masterpieces)

Nostalgic Memories 25FPS 1280X720

Game screening room 25FPS 1280X720

​​ 6. Sound effect settings

7.Microphonesettings

​ 8. OBS interface for fools to quickly get started setting up (lol)

           Add a scene: Move the mouse to the scene, right-click to add the scene, no settings are required, just confirm.

Source: Right click, add game source, as shown in the figure:

9. After the addition is completed, enter the game loading screen and follow the above steps to add a game source. After ensuring that the server and streaming codes are filled in correctly, select start streaming. After entering the game, change the image to borderless or full-screen mode.

The above is the overall usage method of OBS Studio for your reference.
