What is a 4K-HDMI Encoder?
An HDMI encoder is a device that captures high-quality video and audio from an HDMI source (like a camera, gaming console, or computer) and converts it into a digital format for live streaming or recording. It supports 4K resolution, delivering crisp, detailed visuals that make your content stand out.
How Does a 4K Encoder Work?
- Input: The encoder receives uncompressed video and audio signals via HDMI.
- Encoding: It compresses the data using codecs like H.264 or H.265 to reduce file size without sacrificing quality.
- Output: The encoded data is sent to a streaming platform (e.g., YouTube, Twitch) or recorded for later use.
