We can record videos using a digital camera as well as a video camera. But everyone advices to use Video Cameras for recording videos. But do you know why video cameras are recommended?

1) Digital camera's use low bandwidth storage formats as they have less memory. As a result it stores highly compressed and poor quality videos. But video camera use high bandwidth storage formats that have better quality
2) The optical lens of digital cameras are more suitable for capturing still images. So it is very difficult to capture videos with motion.
