Chessgames for example is one site.
Where can I watch Masters game and control speed?

365chess is a (free) internet opening database. You don't even need to register an account. They have millions of Master games on file, although you have to dig through a few menus to find them.
Reti vs Bogoljubow (1924) New York (365chess.com)
Chessgames.com is a similar site, with no opening database but lots of Master games.
Richard Reti vs Efim Bogoljubov (1924) Richard VIII (chessgames.com)

I just can't understand what the OP meant by that "control speed".
If you are watching a video, you don't have any control over how fast the commentator goes through the game.

I can go back and watch that part again. I can even stop the video and play the moves on my board and think as much as I like.
