Rankings answer the wrong question, because the best model for a 30-second brand hero is not the best model for two hundred ad variants, and no ordering captures both. Four questions eliminate most of the field in about a minute, and then you test the two survivors on your own prompt rather than trusting anyone's leaderboard.
The four questions
1. How long is the clip? Most models cap at 5 to 10 seconds. Wan 3.0 and Seedance 2.5 reach 30 in a single pass. If you need one continuous 20-second take, that requirement alone leaves you two options and the decision is nearly made. See best AI video generator for long clips.
2. Do you need audio in the same pass? Gemini Omni Flash always generates it. Veo and Kling make it optional and roughly double the per-second rate when on. If you are laying music over everything anyway, generating silent halves the bill.
3. Is a person or product identity involved? If a face or a specific product has to stay consistent, you need reference conditioning, which narrows the field sharply. See how to keep characters consistent.
4. Is this a draft or a deliverable? Drafts should run on the cheapest tier that shows composition. Deliverables earn the expensive model. Teams that use one model for both overpay on drafts and under-deliver on finals.
The price ladder, for calibration
Canon 8frame credit prices, a credit is $0.01 at pack rate:
| Model | Clip | Credits |
|---|---|---|
| Wan 3.0 (480p) | 5s | 24 |
| Veo 3.1 Lite | 8s with audio | 54 |
| Wan 3.0 Prime | 5s, any resolution | 34 |
| Kling v3 Standard | 5s with audio | 86 |
| Gemini Omni Flash | 8s with audio | 135 |
| Seedance 2.5 | 5s at 720p | 157 |
| Veo 3.1 Standard | 8s with audio | 448 |
Test properly, which takes twenty minutes
Use your actual prompt, not a demo prompt. Models differ most on the specific thing you are asking for.
Run each model three times. One generation tells you nothing about consistency, which is the property that decides your real cost.
Judge as a set, side by side, at the same size. Sequential viewing flatters whatever you saw last.
Count attempts to a usable clip, not quality of the best one. A model that lands one in two beats a prettier model that lands one in five, at any price.
Why cheapest per clip is rarely cheapest
The metric that matters is cost per usable clip, which is per-clip price multiplied by attempts. A 24-credit model needing five attempts costs 120 credits for one shippable shot. An 86-credit model landing it in two costs 172, and takes a third of the time. For drafts the cheap model still wins because rejects are the point; for finals it frequently does not.
This is also why prompt quality is an economic variable rather than a craft one. A specific prompt lowers attempts, which lowers real cost more than switching models does.
The routing that most teams end up with
Draft on a cheap tier. Resolve composition on stills, which are ten times cheaper than clips. Move the survivor to the model whose strength matches the shot: prompt adherence for directed shots, motion character for energy, reference conditioning for identity. Finish once.
FAQ
What is the best AI video model overall? There is no overall, which is the point of this page. There is a best model for a shot with a stated length, audio requirement, identity constraint, and budget.
Should I stick to one model? Only if your work is uniform. Most teams route per shot, which is easier when the models share one credit pool and sit on one surface.
How often should I re-test? Quarterly, and whenever a model family ships a new generation. The ordering has changed materially twice in 2026.
