In early August 2025, NIM Video introduced a major update to their NIM Stories tool: support for character reference images and multilingual narration based on the prompt’s language. This new feature allows you to upload up to three reference images to help keep character appearances consistent throughout a video—something I’ve really been looking forward to.
NIM Stories has been out for about a month now, and I’ve been using it regularly. It’s an easy-to-use tool for creating short, narrated videos with background music—all generated from a simple text prompt. Overall, I’ve been impressed with how quickly it assembles high-quality results. But one issue I ran into early on was character consistency. In previous stories I created about historical figures, the main character often changed appearance from scene to scene, which made things confusing.
The NIM Story creator includes quite a few useful options, such as:
- Visual style
- Image model
- Voice selection
- Tone of narration
- Captions on/off
- Background audio
- Video length (choose between 10–20 seconds and 40–60 seconds)
With the new character reference feature, I decided to test it out by making a 40-second story about William Walker, a 19th-century American who tried to take over parts of Latin America. I uploaded a single portrait of Walker as a character reference—and I was genuinely pleased with the results. The character remained visually consistent throughout the video, which really helped the storytelling feel more polished and coherent.
I’ll definitely be exploring this feature more in the coming weeks, especially since NIM now allows up to three different character references per story. That opens the door for more complex narratives with multiple people—historical debates, fictional scenes, or even simple interviews. I’d still love to see more flexibility in visual pacing and scene composition, but the progress they’ve made already makes NIM Stories feel far more usable for character-driven storytelling. Looking forward to seeing how this evolves.
