Recording CRT TVs can be a challenge due to the way they generate images. Unlike modern TVs that use digital signals, CRT TVs use analog signals that are constantly changing. This makes it difficult to capture a clean, stable image.
However, there are a few different ways to record CRT TVs, each with its own advantages and disadvantages. One common method is to use a video capture card. This is a device that plugs into your computer and allows you to capture video from any source, including a CRT TV. Video capture cards can be either internal or external, and they vary in price and quality.
