Video encoding: supports custom resolution (up to 8K), frame rate (up to 120fps), and bit rate, provides x264/x265 hardware accelerated encoding (such as NVIDIA NVENC), and balances image quality and bandwidth usage.

Low-latency optimization: Built-in low-latency mode, combined with adjustment of push streaming parameters, achieves second-level latency, which is suitable for highly interactive live broadcast scenarios.

Real-time effects and filters

Visual special effects: Supports color correction, blur, masking, cropping and other effects to enhance picture expression.

Transition animation: Provides scene transition effects such as fade in and fade out, sliding switching, etc. to enhance the audience's visual experience.

Multi-format recording: Output MP4, MKV, FLV and other formats, support segmented recording (such as automatic splitting every 15 minutes) and manual marking of key nodes.

Virtual camera: Output the OBS screen as a virtual device, which can be called by third-party software such as Zoom, Teams, WeChat Video, etc., to achieve the integration of "live screen + real-time interaction".

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 monitor 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 the desktop. This way you can live broadcast and do other things to prevent unintentional data leakage.

4) Slide show: add a variety of pictures by yourself and show them to the audience in the form of slides.

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

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 the 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 settings required.

⑧Preview streaming: Simulate the live broadcast screen without live broadcast. You can test whether frame skipping, bit rate changes, screen adjustment and other data are available.

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

PS: There are two red bars. The left side represents the microphone output volume and the right side represents the sound output volume. Click the red bar to adjust the output volume. 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:

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.)
