![]() ![]() It’s important to note that “ultra fast” uses the least CPU power while going down towards “medium” uses more CPU. In most cases, it is sufficient to keep the CPU pre-configuration at “very fast”, but if you have a CPU with enough power, you can also try out more powerful options here or reduce the utilization, if your CPU is not that new anymore. However, the game itself usually needs some bandwidth, so a maximum of 60% of the total upload should be reserved for streaming. However, you can always change the bitrate during the stream, if viewers are having issues watching.įor the buffer size it is recommended to set the same value as you choose for “Bitrate”. Often a bitrate between 22 is recommended, which leads to a worse image quality of the stream. This may prevent viewers with a slow internet connection from viewing your live stream if you have chosen a bitrate that is too high. ![]() This means that viewers can’t independently reduce the quality of the broadcast. ![]() Please keep in mind, however, that your channel will not have “transcoding” options available in the beginning. Your Bitrate should never be more than 60% of your internet upload speed. If your internet connection is strong enough, you can choose up to 3500 in the bit rate box. The other quality options have no effect because the quality factor depends on the bitrate or the maximum bandwidth. This function keeps the bitrate and therefore the quality, constant (If you are using a different platform and nothing else is explicitly recommended, you should use CBR there as well). However, since x264 encoding has the most stable performance anyway, it should not be changed.įor Twitch, CBR (Constant Bit Rate) should be selected as the rate control method. OBS supports different encoders if the corresponding technical requirements are met. Note: Never pass on your stream key and change it immediately if you accidentally showed it to the public! You should copy it from your Twitch Dashboard and paste it in OBS on this page. Besides that, you need your stream key for Twitch which you can find on Twitch on your Dashboard > Settings. Most of the time there are several servers that can be used, so you should test them and find out what works best for you. There are some simple tutorials on the Internet that show how to use Open Broadcaster Software, including more in-depth tutorials designed to cover every aspect of the application.First select the platform of your choice from the list and then choose the closest possible server. In the middle there is a secondary transition button, allowing for transitioning to the non-active scene in the left window using user-defined “quick transitions”. When in Studio Mode, there are two canvas preview windows, the left one for modifying and preview of non-active scenes, while the right window is for preview of the live scene (“Preview” and “Program” respectively). The user interface can be switched to a variety of themes, including both dark and light themes, depending on what the user prefers. The upper section has a live video preview, used to monitor and edit the current scene. The control panel has options for starting/stopping a stream or recording, a button to transform OBS to a more professional Studio Mode (see below), a button for opening the settings menu and a button to exit the program. The mixer panel lets the user mute the audio, and adjust the volume through virtual faders, and apply effects by pressing the cogwheel next to the mute button. Scenes are groups of sources like live and recorded video, text and audio. The main user interface is organized into five sections: scenes, sources, audio mixer, transitions, and controls. Advanced users can choose to use any codecs and containers available in libavcodec / libavformat as well as output the stream to a custom ffmpeg URL. ![]() Multiple tracks of audio can be encoded using the AAC codec. Transmission of data is primarily done via the Real Time Messaging Protocol (RTMP) and can be sent to any RTMP supporting destination, including many presets for streaming websites such as YouTube, Twitch, Instagram and Facebook.įor video encoding, OBS Studio is capable of using the x264 free software library, Intel Quick Sync Video, Nvidia NVENC and the AMD Video Coding Engine to encode video streams into the H.264/MPEG-4 AVC format and the H.265/HEVC format. Written in C, C++ and Qt, OBS provides real-time source and device capture, scene composition, encoding, recording, and broadcasting. OBS Studio is a free and open-source software suite for recording and live streaming. ![]()
