When Jonas flees through various terrain and weather conditions at the end of the movie, his wardrobe changes a number of times to where he finally wears a thick winter parka. All the while he never has a backpack or bag or anything with him and the baby when he initially flees on the motor bike. And where could he have even gotten a spare parka from anyway, since the whole society was climate controlled to perpetual summer-like conditions?
When Jonas and the Giver walk home from their first meeting, they pass by some people assembling a tree. From this point on, the shot is flopped (Giver on Jonas' right, and the brake lever and swing arm of the front wheel fork of the bike on the left side). The image stays mirrored until they separate, when Jonas asks about the one before him.
