How do you keep consistency when creating AI videos?

Hey Product Hunt community 👋

I’ve been experimenting with different AI video tools recently, and one challenge keeps coming up again and again:

keeping characters, style, and story consistent across scenes.

Most tools seem to optimize for generating individual images or clips really well —

but once you try to turn that into a full video, things start to break:

• characters subtly change

• styles drift

• voices don’t match

• and you end up re-prompting everything manually

I’m curious how others here deal with this today.

• Do you rely on prompt templates?

• External docs or style guides?

• Manual editing after generation?

• Or is inconsistency just something you accept?

Personally, I’ve been exploring a “shared context” approach where story, characters, and style are defined once and reused — but I’m not convinced this is the best solution yet.

Would love to hear how other makers and creators are approaching this problem 🙏
