what movie does bella turn into a vampire

In the Twilight Saga: Breaking Dawn - Part 1, Bella turns into a vampire after giving birth to her half-vampire, half-human daughter, Renesmee. Edward tries to transform her into a vampire, but she lies completely still, unreactive to his venom. Her mind flashes with memories of her human life, and we see that her veins are being coated by venom to freeze her to be forever eighteen, but on the outside that is unclear. In the movie adaptation, Bellas transformation is almost peaceful. After her transformation, Bella goes on a hunting trip with Edward and meets hunters. After mastering her self-control, Edward brings her to her daughter. Their happiness is cut short when the Cullens vampire cousin, Irina, mistakes Renesmee for an immortal child, a forbidden creation in the vampire world, and reports it to the Volturi.
