Why can't we take some efforts to appreciate That person's efforts to take such a video instead of flashing too much of hatred by pointing out silly silly mistakes and demotivating the efforts of him.

A silly mistake will neither cost him or others too much. Nature of human is to make mistakes. Are you Artificial Intelligence?!
