LTX Studio is a full-on video creation tool that includes a character consistency feature. It combines 3D generative technology and large language models to create a consistent look for your characters across all frames in your video. It also offers Automatic Edits to try to speed up your video creation.
If you prefer a text-to-video approach, Dream Machine AI generates high-quality video from text prompts. It can maintain character consistency and use cinematic camera motion, which is good for storytelling and cinematic projects. The service is free to use with limited video generation, so you can use it to whip up some content in a hurry.
