Ferrari want to establish whether there is enough evidence to lodge a protest that, if successful, could overturn the result of the world championship.
The footage, from Vettel's on-board camera, appears to show the German passing Toro Rosso's Jean-Eric Vergne in a yellow 'caution' zone.
If that is the case, and any protest was upheld, it could mean Vettel would have 20 seconds added to his total race time. That would demote him to eighth place and make Alonso world champion by one point.
