An encoder is a software or hardware component that converts video and audio signals into a compressed digital format that can be streamed over the internet. In OBS, an encoder is used to compress and transmit the video and audio data from your computer to the streaming platform. OBS supports several different encoders, including x264, NVENC, and AMD VCE, each with its own advantages and disadvantages.
When you start a stream in OBS, the software captures the video and audio from your computer and sends it to the encoder. The encoder then compresses the data using a specific codec, such as H.264 or HEVC, and sends it to the streaming platform. The amount of compression applied by the encoder can be adjusted to balance the quality of the stream with the available bandwidth and processing power of your computer.
An encoder is a critical component of any streaming setup, as it determines the quality and efficiency of the stream. Without an encoder, the raw video and audio data would be too large to transmit over the internet in real-time. OBS provides several different encoders to choose from, each with its own strengths and weaknesses. By selecting the right encoder and adjusting its settings, you can optimize your stream for the best possible quality and performance.
