Red Bull's Mark Webber accused Hamilton of causing him to hit Toro Rosso driver Sebastian Vettel by speeding up and slowing down behind the second safety car.
However, a FIA a spokesperson confirmed to Deutsche Presse-Agentur dpa that an official investigation had not been opened although this could occur Friday. A penalty has not been ruled out.
The footage appeared on YouTube footage but has since been taken down and replaced with the message: "This video is no longer available due to a copyright claim by Formula One Management."
Hamilton leads team-mate Fernando Alonso by 12 points in the drivers' standings with just two races remaining and victory in Sunday's Chinese GP in Shanghai would ensure the 22-year-old becomes the youngest driver and the first rookie driver to win the title.
