HDMI capture card is an expansion hardware that can be installed in a computer using an HDMI interface. It is mainly used to capture audio and video signals from various devices. In the scenario of PS4 game live broadcast, the capture card receives the game screen and audio output by PS4 through the HDMI interface, and then transmits the signal to the computer through the USB interface. The video capture software on the computer (such as OBS) will receive and process these signals for live broadcast or recording.
When choosing an external HDMI capture card for PS4 game live broadcast, you need to consider the following parameters:
1. Resolution and frame rate: For PS4 game live broadcast, a capture card that supports 1080P60fps is usually sufficient. If higher image quality is required, a capture card that supports 4K60fps can be sele-cted.
2. Interface standard: The HDMI interface should support HDMI 2.0 or higher to ensure transmission bandwidth and stability. The USB interface should support USB 3.0 or higher to reduce transmission delay and improve image quality.
3. Loop-out function: The loop-out function allows the captured images to be directly output to another monitor or TV, which is very useful for players who need to watch the game screen and perform live broadcast operations at the same time.
4. Power supply method: Some capture cards require external power supply, while others can be powered by USB interface. The selection should be determined according to the actual situation.
5. Brand and model: There are many brands of capture cards available on the market, such as UGREEN, AVerMedia, Elgato, Acassis, etc. When choosing, you can consider factors such as brand awareness, user evaluation, and cost performance.
