Is drupal right for me

Hi all,
I am new to web developing in General. I want to make a website and i searched for a cms to easy my work. I found drupal and like it but I am afraid if it will do what i wish my site to be. I want to make a video sharing site where users have accounts can upload .flv videos post comments, with related video menu etc...
So if i can do this with drupal please tell me Yes or No and to what extent. and u r thanked well if you gave me links to sites like what i have discribed.
Thanks in advance..
