I'm trying to use Sora to create a short explainer clip for a new meeting tool we're launching. I want a friendly animated character to guide the viewer through it.
But when I generate different scenes, the character's face, clothes, and even hair color keep changing slightly between shots. It breaks the flow. Is there a specific way to describe the character or a setting to lock it down? I'm not looking for perfect Hollywood CGI, just basic consistency.
You're hitting the fundamental limitation of these generative video tools - they don't have a persistent "character" model. Each generation is its own interpretation of your text. I learned this the hard way on a client project last year.
We tried for weeks to get consistent characters across a training series. What finally worked wasn't better prompts, but a shift in approach. We generated a single perfect character image in Midjourney, then used that still image as the *primary visual* and animated around it with simple motion graphics. The "character" was mostly static while other elements moved. It's a compromise, but it maintains consistency.
For your use case, if you're set on using Sora for the whole thing, you'll need to accept a looser style guide. Describe your character in exhaustive, almost annoying detail for every single shot prompt, and even then expect variations. It's less about a "setting" and more about brute-force iteration until you get clips that are close enough to cut together. Honestly, for a product explainer, you're probably better off with a traditional animation tool or even a template-based service.
Migrate once, test twice.
That's such a great hack, using a static Midjourney image as the anchor! I ran into something similar making an email course. Trying to keep a "host" character consistent in different scenes for each lesson was a nightmare.
But what about the character showing basic expressions? For a friendly guide, a smile or a raised eyebrow would really help. Did you find a way to add subtle facial animation to that still image, or did you just keep it completely static?
Yeah, the character consistency issue is the main headache with these tools right now. I don't think there's a magic prompt word or setting that will "lock" a model for you, unfortunately.
What's worked for me is to generate the character once, get a frame I like, and then use that exact image as a reference in every subsequent prompt. You have to describe it as "the same character from before, with the same green sweater and short black hair," and even then it's a gamble. It gets you closer, but you'll still see drift over several scenes.
For a short clip, you might get away with it if you keep the descriptions super repetitive and specific. But for anything longer, the static-image-as-anchor method the other user mentioned is probably your most reliable bet.
Prompt engineering is the new debugging
The advice you're getting about reference images is optimistic. You can describe that "green sweater" until you're blue in the face, but these models don't understand persistent objects. You'll still get drift, just slower. It's baked into how they work.
They're great for generating variations, not for maintaining a spec. For a product launch video, why introduce that risk? The "friendly guide" turning into a different person shot-to-shot makes your tool look sloppy, not innovative.
Use Sora for b-roll or abstract transitions. Hire a freelance animator on a platform like Fiverr for the character. The total cost and headache will be lower than fighting an AI for consistency it can't deliver.
trust but verify
You're discovering the core problem. It's not a setting or a magic prompt.
These tools generate, they don't remember. You can't lock a character because there's nothing to lock. The "basic consistency" you're looking for is the exact thing the tech can't do yet.
Save yourself the frustration. Use Sora for your background visuals and animate a simple 2D character overlay separately.
CRM is a means, not an end.
You've hit on the most common frustration right now. The short answer is there isn't a setting or a single perfect prompt to lock a character down. The suggestions here about using a reference image are the right track for staying within Sora.
For a product launch video, though, consistency is pretty crucial. My gentle nudge would be to question whether a fully AI-generated character is the right tool for this specific job. You could spend hours generating and regenerating, hoping for a stable look, when that effort might be better spent on a different approach.
Have you considered generating your character once, exporting a still you love, and then using that as a key visual in a simpler motion graphics template? You keep the friendly guide, but you sidestep the inconsistency battle. Just a thought
