Audio problem: Tintin places part of the meteorite on the raft. When it lands, it makes a sound as if it landed on a wooden floor. The raft is made of plastic and has air in it. Not the landing sound you'd expect. (00:20:15)
Audio problem: The Aurora crashes into a ship. As Tintin and Haddock fall over, a glass related smashing sound is heard. There is no glass there to cause it. (00:11:30)
Audio problem: When Tintin first sees the telescope, he says "What?" His mouth is out-of-sync when he says this. (00:02:50)
Audio problem: When Tintin says "Maybe we should go back inside" his mouth doesn't move. (00:09:20)
Chosen answer: If Hector was seriously intent on removing King Ottokar's scepter from the glass cage holding it and launching it through the window with the camera, then Hector would have been forced to knock out the two guards so they would not have interfered with Hector's plan as soon as he removed the scepter from the glass. As for Hector, himself, was explained when Tintin was explaining how Hector stole the scepter. Tintin placed a twig inside the camera and it launched out of the camera. Hector would have placed the scepter inside of the camera, and would have been knocked unconscious due to the spring effect created when the scepter had been launched.
