If you have a lot of old VHS tapes or DVD discs, it is easy to convert them to files on your computer. With a video grabber, the TV signal from your old camera or VHS player enters the computer which converts the image to a file. If your device has an RCA output or can use an RCA adapter, you can convert the image or audio signal to a digital file.
If you want to stream or do let's plays, you may also enjoy a video grabber. Connect your Xbox, Playstation, Wii or a fourth game console and record your activity on the screen. Some models can also be used with your desktop computer. The quality is also improved significantly, so you can now record in Full HD or 4K at 30 or 60 FPS.
