What kind of tape camera did I use before? How to change the shot video into the current CD or save it in the computer? thank you

First, if the old analog video tape is used, an acquisition card needs to be added to the computer to convert analog information into digital signals and collect them on the computer; Second, if you are using a tape digital video camera, you can capture directly if there is a 1394 interface on the computer, otherwise you can buy a 1394 interface card (it is very cheap, you can buy it for about 100 yuan) and install it on the computer to capture. Third, after collection, you can use video editing software (novice recommended "Sound Shadow") to edit, score, subtitle, transition special effects and other processing of video files and then burn them directly into DVD.
