One of the most exciting use cases is the ability to build consistent AI characters that appear
seamlessly across multiple video scenes. Whether you’re developing a brand mascot, a
virtual influencer, or an animated e-learning avatar, the challenge remains the same:
how do you keep your character’s look, voice, and personality consistent from start to finish?
1. Start With a Detailed Character Prompt
Begin by creating a character bible with all the details: appearance, clothing style, personality,
and tone of voice. When using AI video generation tools like Runway, Pika Labs, or Stable Video Diffusion,
feeding in a structured prompt ensures your character looks the same across scenes.
