I apologize for any mistakes in my translation.
I'm not very experienced myself, here are the recommendations I can give.
1- looking back from the car ahead; This is so wrong, this is what gave me the most headache.
2- shaking the camera too much; yes it can be funny and fun to do it once in a while but it's bad when done too often.
3- Changing players frequently. The man who goes on his way alone in the 15th row, make sure no one cares
4- We would like to watch the front one, but if the front one has lost a lot of difference and is advancing alone, we should not show it, the camera should be in the rear one among those advancing collectively.
5- exaple, the 1st is very far, the 2nd is in the future, 3rd-4th-5th. The person is close to each other and they are in competition, you should have us watch the competition through the 5th person.
Someone who knows can correct me if I'm wrong.
