Almost every “best AI video tool” comparison puts Runway, HeyGen, InVideo and a raw model API in one table and ranks them. That is like ranking a camera against an edit suite against a stock library — they are not alternatives to each other, and the winner is decided entirely by which one you needed.
There are three categories. Work out which one you are shopping in and most of the decision disappears.
The three categories
1. Model APIs — you write code
You call an endpoint, footage comes back. Seedance, Kling, MiniMax, Veo and the rest, reached either direct from the model owner or through an aggregator that resells many models behind one key.
Cheapest by a distance — as little as three cents per second of output at the low tiers, against roughly a dollar a clip on the interfaces. You also get model choice, batching, and identical behaviour wherever you are in the world.
What you give up: there is no gallery. Files come back to a folder, and reviewing generative work means comparing dozens of near-identical takes, which a folder is terrible for. You will end up building a review layer, and that is a software project sitting between you and your first video.
2. Creative interfaces — you make videos by hand
Higgsfield, Runway, Dreamina, Magnific, CapCut. A timeline, camera-motion presets, shot controls, a library of what you have made.
Roughly ten to twenty times the per-second cost of an API, and for many people that is not a markup, it is the price of the thing being usable at all. If you do not write code, the cheap route is not cheaper for you — it is unavailable.
What to watch: credit systems that do not roll over, “unlimited” that means rotating promotional windows, and regional availability that varies more than the marketing suggests.
3. Avatar generators — a person talking to camera
HeyGen and the audio-driven avatar class. Give them a face and an audio track, get accurate lip-sync in front of a background.
The limit is structural: the character is composited in front of a scene, not generated inside one. She cannot pick anything up, walk behind anything, or be reacted to. For training videos, explainers and localisation that does not matter at all. For anything where the character acts within a place, no avatar tool solves it, because it is a property of the category.
The comparison, priced
| Tool | Category | Cost | Pick it when |
|---|---|---|---|
| BytePlus / model direct | API | from ~$0.03/s | Volume, and you can code. |
| Aggregators (EvoLink, Replicate, fal) | API | ~$0.10–0.47/s | You want several models behind one key. |
| Dreamina | Interface | ~$1.06–1.29 / 8s | First-party access to ByteDance models, no code. |
| Higgsfield | Interface | ~$1.55 / 8s | Camera presets matter; you accept non-rolling credits. |
| Magnific | Interface | ~$1.86 / 8s | |
| Runway | Interface | ~$2.88 / 8s | Mature editor, established workflow, highest price. |
| InVideo | Assembly | subscription | You want script-to-finished-video, not clips. |
| CapCut | Editor + generation | subscription | You are editing anyway and generation is a bonus. |
| HeyGen | Avatar | subscription | Talking head, many languages, at volume. |
| Pippit | Ecommerce ads | free tier; ~$10/mo | You sell products and need ad creative at volume, not narrative video. |
A fourth category worth naming: tools built for product ads rather than video as such. Pippit takes a product URL and returns a finished UGC-style advert — script, voice, captions and all. It is bad at everything discussed above and very good at the one thing none of the others do well, which is the fortieth variation of the same ad.
The pairings people actually search for
Higgsfield vs Runway — same category, so it is a real comparison. Runway costs roughly double per clip and has the more mature editor; Higgsfield is cheaper with stronger camera presets and a credit system that punishes underuse. Decide on whether you produce steadily or in bursts.
Higgsfield vs Kling — not a fair fight, because Kling is a model and Higgsfield is a shop that sells access to models. The real question is whether you want Kling through an API at a tenth the price, or through an interface.
InVideo vs CapCut — both assembly-first, and mostly a workflow preference. InVideo aims at script-to-video in one pass; CapCut is an editor that gained generation.
Anything vs HeyGen — almost always a category error. If the comparison is happening at all, the question is usually whether you need an avatar or a performance.
Seedance vs Kling vs MiniMax — a genuine model comparison, and the answer is unintuitive: in our own testing the cheapest, least impressive-looking model won, because consistency across forty shots beats brilliance in one.
How to choose in three questions
- Does a specific character have to recur? If no, buy on price and ignore most of the consistency discussion. If yes, you need reference-to-video support and a disciplined anchor-image workflow whatever you pick.
- Does that character have to speak? If yes, you need generation-native audio, which is expensive per second and has no cheap substitute worth using.
- Will you write code? This is the real fork. Yes puts you in category one at a tenth the cost plus a build. No puts you in category two, and the premium is what the interface is worth.

Method
Prices observed August 2026. Per-second figures come from measured production spend where marked; the rest are provider-quoted. This category reprices monthly and models version up faster than that, so re-check anything before committing money to it.
