Keeping Characters Consistent Across AI-Generated Shots

The giveaway is almost always the same: a recurring host, narrator figure or mascot whose face subtly shifts from shot to shot, because each image was generated independently with no memory of the last one. Consistent characters exists specifically to stop that from happening.

Why this happens by default

Every AI-generated image is, by default, its own independent generation — a fresh interpretation of a prompt with no awareness of any image generated before it. Ask for "a woman narrator in a cinematic style" ten times and you get ten different plausible women, not the same one ten times. For a single establishing shot, that is fine. For a figure meant to recur across an entire video, it reads as an obvious tell.

What consistent characters actually does

Turned on from a switch on the Visuals screen, it keeps a reference image of a character and feeds it back into later generations of that same character, so the model has something concrete to match rather than reinterpreting the prompt from nothing each time. The result is a figure whose face stays recognizably the same across the shots it appears in, rather than a new face each time.

It is opt-in, not automatic — most scenes in most videos do not need it, and turning it on for a background or incidental figure would be unnecessary overhead. It earns its place specifically when the same figure needs to appear more than once and look like the same person each time.

How it differs from an avatar or a cloned voice

These solve genuinely different problems and are easy to conflate. An avatar, as some competing tools offer it, is typically a template or real-time presenter model — a specific kind of "face" the tool provides, often with lip-sync to narration. Consistent characters is not that: it keeps whatever figure you generated or referenced stable across shots, whether that is a stylized illustrated host, a recreated historical figure, or an original character — it does not supply a pre-made presenter, and it has nothing to do with voice.

A cloned voice, separately, is about audio — some of the voice engines you can connect support cloning a specific voice. That is unrelated to whether the visual figure on screen looks consistent from shot to shot; a video can use a cloned voice with no recurring visual character at all, or a consistent visual character with the default free voice.

When to use it

• A recurring channel host or narrator figure who appears across most or all of an episode.
• A specific historical or fictional figure who needs to be recognizable across several separate scenes.
• A mascot or brand character reused episode to episode.

Skip it for one-off background figures, crowds, or anyone who only appears in a single shot — there is nothing to keep consistent, so it is just unnecessary setup.

The bigger picture

This sits alongside the rest of the visual pipeline — AI images, stock photos and stock video, chosen per scene by AI Director or by hand. See AI images vs stock footage for when to reach for a generated image in the first place, since consistent characters only matters once you have already decided a scene needs one.
