Can I make a movie with a digital camera? I am a student of digital media. What is the video quality of digital DV camera?

My understanding is this: What are the disadvantages and advantages of the old-fashioned desktop camera in school? This is a video recorder that uses analog tapes. The recorded signal is not easy to save, and the analog signal is attenuated greatly during the copying process, and the horizontal clear line is not too high. Digital cameras also use magnetic tape, and the key is that digital signals are not easy to be lost and stored during shooting and acquisition. In the process of acquisition and production, due to the use of digital signal transmission, there is no loss in theory and the level is clear and the line is high.
