In addition to hardware encoders, OBS also allows users to configure bitrate settings, which control the amount of data used to represent video per second. Lower bitrate settings can reduce CPU usage but may result in lower video quality, while higher bitrates will consume more CPU resources but deliver better video quality. Finding the right balance between bitrate and CPU usage is crucial to achieve optimal performance.

Setting 1.1: Bitrate

The bitrate setting determines the amount of data used to represent video per second. Lowering the bitrate can significantly reduce CPU usage, but it may result in lower video quality, especially in high-motion scenes. On the other hand, increasing the bitrate will consume more CPU resources but deliver better video quality. It is recommended to experiment with different bitrate settings to find the right balance for your specific streaming or recording requirements.

To adjust the bitrate in OBS, navigate to the "Output" tab in the settings menu and locate the "Bitrate" section. Here, you can enter your desired bitrate value in kilobits per second (Kbps). Keep in mind that higher bitrate values will require a faster internet connection to maintain a smooth streaming experience for viewers.

Furthermore, OBS allows for bitrate control during live streaming by using the "CBR (Constant Bitrate)" or "VBR (Variable Bitrate)" settings. CBR maintains a consistent bitrate throughout the stream, while VBR adjusts the bitrate dynamically based on the complexity of the content being streamed. Choosing the appropriate bitrate control option can help optimize CPU usage while ensuring a smooth and high-quality streaming experience.

Setting 1.2: Keyframe Interval

The keyframe interval, also known as the I-frame interval, determines how often a full frame is sent in the video stream. This interval plays a crucial role in video compression and affects both video quality and CPU usage. A longer keyframe interval results in better compression but can increase CPU load, while a shorter interval may reduce CPU usage but result in larger file sizes. It is essential to find the right balance to minimize CPU usage without compromising video quality.

In OBS, you can adjust the keyframe interval by navigating to the "Output" tab in the settings menu and locating the "Keyframe Interval" section. Here, you can set the keyframe interval value in seconds. The recommended value is usually between 2 and 4 seconds, but it may vary depending on your streaming or recording needs.

By optimizing the video encoder settings, such as using hardware encoders and fine-tuning bitrate and keyframe interval values, OBS users can significantly reduce CPU usage and achieve smoother streaming and recording experiences.

Setting 2: Audio Encoder

In addition to video encoding, OBS also employs audio encoding to compress and transmit audio data during streaming or recording. Similar to the video encoder, OBS offers several audio encoder options with varying CPU usage levels.

By default, OBS uses the AAC audio encoder, which provides a good balance between audio quality and CPU usage. However, if CPU usage is a concern, OBS allows users to switch to alternative audio encoders like MP3 or FLAC, which can offer lower CPU usage at the expense of some audio quality.

To change the audio encoder in OBS, navigate to the "Output" tab in the settings menu and locate the "Audio Encoder" section. Here, you can select your preferred audio encoder from the dropdown menu.

It is important to note that while using a lower CPU usage audio encoder may reduce overall CPU load, it may also result in a slight compromise in audio quality. It is recommended to test different audio encoder settings and choose the one that strikes the right balance between CPU usage and audio quality for your specific streaming or recording needs.

Setting 3: Scene Optimization

OBS allows users to create multiple scenes that can be switched during streaming or recording to present different layouts or setups. However, having too many complex scenes with multiple sources can increase CPU usage. To optimize CPU usage, it is advisable to simplify or optimize scenes by reducing the number of sources or resizing and cropping them to eliminate unnecessary rendering processes.

To modify scenes in OBS, navigate to the "Scenes" section in the main OBS window. Here, you can access each scene and make the necessary modifications to reduce CPU usage. This may involve removing unnecessary sources or adjusting the size and position of sources to minimize the rendering workload.

By streamlining scenes and minimizing the number of sources, OBS users can effectively reduce CPU usage while maintaining a smooth streaming or recording experience.

Setting 4: Hardware Acceleration

OBS supports hardware acceleration, which can offload some of the CPU-intensive tasks to the GPU, resulting in lower CPU usage. Hardware acceleration utilizes the capabilities of the graphics card to handle certain computational tasks, such as video decoding and rendering, rather than relying solely on the CPU.

To enable hardware acceleration in OBS, navigate to the "Advanced" tab in the settings menu and check the "Use hardware acceleration when available" option. This will utilize the GPU for certain operations, reducing the CPU load and improving overall performance.

It is important to note that hardware acceleration may not be available on all systems or may have limitations based on the hardware and GPU capabilities. Users should ensure that their system meets the requirements for hardware acceleration and test its effectiveness in reducing CPU usage.
