This section is about electronic devices. For the music video by Weezer, see. Special electronic circuitry is required to capture video from analog video sources. At the system level this function is typically performed by a dedicated video capture device. Such devices typically employ integrated circuit to convert incoming video signals to a standard digital video format, and additional circuitry to convey the resulting digital video to local storage or to circuitry outside the video capture device, or both. Depending on the device, the resulting video stream may be conveyed to external circuitry via a computer bus (e.g., PCI/104 or PCIe) or a communication interface such as USB, Ethernet or WiFi, or stored in mass-storage memory in the device itself (e.g., ).
The USB 2.0 Video snap shot adapter with audio can capture High-quality video and audio file direct by USB 2.0 interface without sound card. The installation is very simple and the external power is not necessary.
