What is a video capture card?
Video capture card (Video Capture Card), also known as video capture card or video card, is a hardware device that inputs external video signals into a computer and converts them into digital signals that can be recognized and processed by the computer. Specifically, a video capture card can receive video data (sometimes including audio data) output from video devices such as ana-log cameras, video recorders, LD video disc players, and televisions, and then convert these data into a digital format that can be recognized by the computer and stored on the computer's hard disk for subsequent editing, processing or playback.
Functions and features of video capture cards:
Signal conversion: Converting ana-log video signals into digital video signals is the most basic function of a video capture card.
Data storage: Store the converted digital video data on the computer's hard disk to form an editable and processable video data file.
Editing and processing: Through the video editing software on the computer, you can perform post-editing processing such as cutting, adding filters, subtitles, sound effects, setting transition effects, and adding various video special effects to the video data files stored on the hard disk.
Format conversion: The edited video signal can be converted into standard VCD, DVD and online streaming formats, which is convenient for dissemination on the network or playback on other devices.

Notes on replacing the video capture card driver
Before uninstalling the old driver and installing the new driver, make sure your computer is connected to the Internet so that you may need to download additional components or updates during the installation process.
If you encounter any problems when installing the new driver, please consult the user manual of the video capture card or contact the manufacturer's technical support team for help.
After installing the new driver, restart the computer to ensure that all changes can take effect.
If your video capture card is installed in your computer through a PCI or PCI-E slot, then before replacing the driver, you may need to uninstall the old driver on your computer, then shut down the computer, unplug the power cord, open the case and unplug the old video capture card (if you plan to replace it). However, please note that this is usually not a necessary step for replacing the driver unless you need to replace the hardware at the same time.
