The breakthrough feature is single-image character consistency: upload a reference photo and the model maintains that character's appearance across generated clips. For narrative filmmakers, this solves one of the biggest pain points in AI video. Before Gen-4, every generation was a roll of the dice on whether your character would look the same. Now you can build stories with recurring characters.
