Main application:

1, Digital video information can be captured and stored and played out

2,Many video capture cards can acquire audio while capturing video information, allowing the audio and video sections to be simultaneously saved and synchronized when digitized.

 3,The video signal is collected into a computer and saved on the hard disk as a data file
It is an essential hardware device for our video processing。Through it, we can transfer the video signal captured by the camera from the camera tape to the computer, and use the relevant video editing software to perform post-editing processing on the digitized video signal.

For example, cutting the screen, adding filters, subtitles and sound effects, setting transition effects, and adding various video effects, etc. Finally, the edited video signal is converted into standard VCD, DVD, and online streaming media and other formats to facilitate communication.
