CPU usage accelerates causing serious increase of macbook temperature especially when playing videos. What can be the reason?

Increased electrical current through the CPU components, coupled with the intrinsic resistivity of all conductors and semiconductors, results in the generation of energy in the form of heat. From a microscopic point of view, the energy transfer results from collisions of the electrons which carry the current.

Whether the resulting increase in temperature is "serious" depends upon how high it is. How high is it?

And how to escpe this problem?

Don't play the videos.

kewl ;)

also he can try to go superconductive mode...

more video - more compressing/decompressing - more calculations - more operations on CPU - more power to CPU - more heat from CPU. Nothing you can do exept clearing vent hoses from dust and everything preventing airflow

just take a look from top and bottom at wide hole where screen is attached when it is half-opened. is it dusty? If not - forget it, its okay. If yes - show it to somebady at genius bar and ask him how to clean cooling system. I can do it myself but can't recommend it to you by yourself.
