  Capture cards are used to connect external video, audio signals, or other peripherals to a computer or streaming device and transmit them as part of the live content. Here are a few main reasons to use capture cards for live streaming:
Capture cards
  High-quality signal acquisition: The acquisition card can be connected to professional cameras, high-definition cameras, audio equipment and other external devices to ensure high-quality signal acquisition of live content. Compared to regular cameras, professional devices provide higher image quality and clearer audio input, helping to provide a better viewing experience.
  Multichannel signal capture: Capture cards often support multiple input channels, which means you can connect multiple cameras or other external devices at the same time to capture video or audio from different angles, adding variety and richness to your live content.
  Real-time transmission: The capture card can transmit the captured video and audio signals to the computer or streaming media server in real time. In this way, the live broadcast platform can receive signals in real time and forward the content to the audience, enabling the audience to watch the live content in real time.
  Low latency: Using capture cards to transmit signals can achieve low latency, especially for scenes that require timely interaction in live content, such as live games or online Q&A, low latency is very important.
  Multi-platform compatibility: Most capture cards support common live streaming platforms and streaming services, such as Twitch, YouTube, Facebook, etc. This allows livestreamers to seamlessly push the captured signal to different platforms.
