Extended data:
Under the current technical conditions, the latest European and American movies appeared in the domestic pirated market three days after they were released in China. This kind of piracy recorded by cinemas is called "gun version" in the jargon of disc lovers.
"Gun version" usually refers to movies pirated from cinemas with digital cameras. Sometimes a small tripod is used, but most of the time it is not available, so the camera will shake. Because the sound is recorded from the camera's own microphone, the audience's laughter and other sounds are often recorded, especially comedies. Due to these factors, the image and sound quality is usually poor. But sometimes it's a good thing that the cinema is empty, and it will record better sound.
