A man in a black shirt and brown pants is jumping in the air performing a karate kick towards a man in a red shirt and black hat.
Actors who are also martial arts experts face off as opponents with the good guy in brown and black and the bad guy wearing red and a black hat.
You can not infer they are martial arts experts.
Sentence 1 does not mention that these men are actors, martial arts experts or opponents. There is not mention as to whether there is a good guy or a bad guy.
Just because a man is performing a karate kick or having a karate kick performed towards him does not make him a martial arts expert. Wearing brown and black does not make imply that the man is the good guy. Wearing a red shirt and black hat does not imply that a guy is the bad guy.
