Friend upstairs, your understanding and explanation are outrageous.

1 What’s wrong with shooting videos with a DSLR?

It's normal, for example, Canon's 5d2. Since its launch, countless people have used it to take pictures, and there have been countless high-quality works, such as McDonald's commercials during the World Cup in South Africa, Ning Hao's short films, etc. The quality of the videos shot by the 5d2 is excellent.
