How to extract video files from the video tape of the camera

1. By recording analog signals, computers need equipment (such as built-in TV cards) to receive analog signals. DV is connected to the computer through the video output line, which is completed by the recording software. There are many softwares available, such as audio and video, public relations, film production and even storm video. Because of the quality problem of analog signal, it is not recommended.

2. Through digital signal acquisition, the computer needs to be connected to 1394. The acquisition quality depends on the performance of 1394 card, and the price ranges from tens to thousands. After the connection, it can be obtained through audio-visual software, PR, film production and other software. DV-AVI is recommended as the acquisition format, and then it is converted into MPEG-2 format by video compression software (such as WINAVI).
