If you're searching for an AI video consistent character setup, the answer isn't a model, it's an order of operations. Lock the character as a still image first, then drive every clip from that still. On 8frame the cheapest version of that is Seedream V5 at 6 credits for the portrait and Kling 2.6 Pro at 47 credits to move it, so a locked character costs about 53 credits instead of the 282 you'd burn re-rolling text-to-video and hoping six faces match. Here's the full workflow, the reference-capable video models, and where this still breaks.
TL;DR
- Don't fix consistency in the video model. Fix it in the still, then animate the still.
- Cheapest lock: Seedream V5 at 6 credits, accepting up to 14 reference images. Nano Banana 2 at 8 to 22 credits by resolution is the other good option.
- Reference-capable video, cheapest first: Kling O1 Reference at 73 credits, Kling O1 Video at 109, Seedance 2.5 at 157 (native audio, up to 30 seconds), Veo 3.1 multi-reference at 448 for the premium lock.
- Nothing here is perfect. Drift still shows in side profiles, in takes over 8 seconds, and any time two conditioned faces share a frame.
Why text-to-video can't hold a character
Text-to-video generates a fresh face every run. Same prompt, same model, two different people: jaw structure moves, eye spacing moves, hair color lands in a range rather than on a value. For one standalone clip that doesn't matter. The moment two clips cut together, it's a production stopper. The mechanism is in what is character consistency in AI; the practical version is that a prompt is a description, and descriptions have many valid answers.
A reference image is a constraint instead of a description. The model has to satisfy the pixels you handed it, so it can't invent a different nose. That's why the workflow below spends its first 6 credits on an image rather than a clip.
The expensive mistake is doing it in the wrong order. Re-rolling text-to-video until a face looks right costs 47 credits per attempt on Kling 2.6 Pro. Six attempts is 282 credits, about $2.82 at pack rate, and you end up with one face you like and no way to reproduce it in shot two. Locking the still first costs 6 credits and makes shot two, three, and twelve trivial.
Step 1: lock the character as a still
Generate the canonical portrait yourself. Don't start from a stock photo, because you want a face nobody else's campaign is also using.
Seedream V5, 6 credits. It accepts up to 14 reference images at once, more than any other image model on the canvas. That matters less for the first portrait and a lot for the follow-ups: once you have a face, you can feed it back alongside a wardrobe reference, a lighting reference, and a location plate, and it holds all of them. At about $0.06 an image, this is the cheapest identity work anywhere in the pipeline.
Nano Banana 2, 8 to 22 credits. Priced by resolution, up to 4 images per run. Reach for it when the character has to survive a 4K crop or when skin and hair detail carry the shot.
Write the prompt around what must stay fixed, not the mood. Age, build, hair length and color, eye color, skin tone, one distinguishing feature, wardrobe with a named color. Mood you can change per shot. Structure you can't.
Step 2: build an angle pack, then storyboard it
One front-facing portrait is not enough. Reference conditioning transfers poorly to angles it hasn't seen, so generate the same character in three to five views: face-forward, three-quarter, profile, and one from a slightly raised camera. At 6 credits each on Seedream V5, a five-image pack costs 30 credits, about $0.30. That pack is the asset. Every downstream clip reads from it.
ShotGrid earns its place here too. It generates a 9-frame reference-consistent grid across narrative beats, so you see your character in nine moments before spending a single video credit, and you catch the shots where they fall apart at image prices instead of at 109 credits a clip.
Step 3: drive video from the still
Two routes, and the cheap one is good enough most of the time.
Image-to-video from the locked still. Feed the portrait as the first frame and prompt the motion. Kling 2.6 Pro at 47 credits is the value default, and because the face is already correct in frame one, most of the identity problem is solved before the model starts.

Reference-capable video models. These read your whole reference pack rather than just a first frame, which is what you need when the character appears mid-shot, at a distance, or in profile.
- Kling O1 Reference, 73 credits, for the multi-reference pass, with Kling O1 Video at 109 credits for the generated clip. The working middle of the market.
- Seedance 2.5, 157 credits. Reference-driven, up to 30 seconds, with native audio, so a continuous take of the character speaking doesn't need a separate pass. Strongest identity preservation in the lineup and too expensive to iterate on. Prove the shot cheap, finish here.
- Veo 3.1 multi-reference, 448 credits. The premium lock, about $4.48 a generation. Worth it for a hero shot where the face is the deliverable, not for the eleven clips around it.
A realistic six-shot sequence: 30 credits for the reference pack plus six Kling 2.6 Pro image-to-video clips at 47 each comes to 312 credits, about $3.12, and every shot reads as the same person. On a $19 Starter plan's 1,000 rollover credits, that's three sequences a month with room left over.

What still breaks
No model here holds a character perfectly, and anyone claiming otherwise hasn't shipped a series. From our own runs, documented in the AI character consistency workflow, the failure modes are predictable enough to plan around:
Takes over 8 seconds. Identity degrades in a single continuous clip past roughly 8 seconds. Write a cut point into the shot rather than fighting it.
Side profiles. Face-forward references don't transfer cleanly to a 90-degree profile. Generate a dedicated profile reference and add it to the pack.
Two conditioned faces in one frame. Accuracy drops sharply when two reference-locked characters share a shot. Generate singles and cut between them for the conversation feel; wide two-shots drift on at least one face.
Wardrobe and props. Reference conditioning pins the face harder than the clothes. If the character wears a specific color across a series, name it in every prompt.
Compositing. Don't paste the reference face onto a clip that drifted. It reads as uncanny every time. Regenerate with a tighter crop reference instead.
FAQ
How do I keep the same character across multiple AI videos?
Generate one canonical still of the character, build a pack of three to five angles from it, and use that pack as the reference input for every clip. On 8frame that's Seedream V5 at 6 credits per image, then image-to-video on Kling 2.6 Pro at 47 credits or a reference-capable model like Kling O1 Video at 109. Never re-roll text-to-video hoping for a match.
Which AI video model is best for consistent characters?
Seedance 2.5 at 157 credits has the strongest identity preservation and runs up to 30 seconds with native audio, so use it for finals. Veo 3.1 multi-reference at 448 credits is the premium lock for hero shots. For volume, Kling O1 Video at 109 credits or image-to-video from a locked still on Kling 2.6 Pro at 47 does the job for a fraction of the spend.
Is character consistency solved in 2026?
No. It's reliable enough for production if you work still-first and keep clips under about 8 seconds, but drift still appears in side profiles, long continuous takes, and shots with two conditioned characters. Plan on regenerating a couple of clips per sequence and the workflow holds.
The whole chain runs on one canvas: generate the still, fan the angle pack out, send it to three video models side by side. Plans start at $19 a month, watermark-free on every tier, at 8frame.co/pricing.
