Compare AI Video Models — Which One Should You Pick?
Six image-to-video models · one credit balance · no subscription
"Which AI video model is best?" is the wrong question — the same photo can look great in Kling and wrong in Veo, and vice versa. The honest answer depends on your image and what you’re making. This page lays out what each of the six models on img2.video is actually good at, what it costs, and how to choose — and lets you run the same image through any of them on one balance, which is the only comparison that really settles it.
The comparison table
Specs below are the live settings on img2.video (verified October 22, 2026). Costs use the Starter rate of 8.25¢/credit; longer or higher-resolution renders scale up, and the exact total is always shown before you generate.
| Model | Best for | Audio | Max length | Resolution | Default cost | Speed |
|---|---|---|---|---|---|---|
| Grok Imagine 1.5 | Fast drafts, memes, fun | Native, free | 10s | 480p–1080p | ⚡25 ($2.06) | Fastest |
| Kling 2.6 | Cinematic motion, people | No | 10s | 720p | ⚡20 ($1.65) | Fast |
| Veo 3.1 Fast | Realism, portraits, keepsakes | Native (4K tier) | 8s | 720p / 4K | ⚡25 ($2.06) | Moderate |
| Vidu Q4 | Longer storytelling clips | Native, free | 16s | 720p–4K | ⚡30 ($2.48) | Fast |
| Seedance 2.5 | Long-form up to 30 seconds | Native, synced | 30s | 480p / 720p | ⚡65 ($5.36) | Slower (long clips) |
| Seedance Mini | Budget everyday clips | Native | 10s | 480p / 720p | ⚡20 ($1.65) | Fast |
Which model should I pick?
Faces and skin stay cleanest; Veo's 4K tier preserves detail on close-ups. Kling is the cheaper 80% as good.
Strong prompt adherence keeps labels and edges stable on a slow camera move, at the lowest HD price (⚡20).
Fur motion reads naturally at 720p; if you're iterating on many takes, Seedance Mini halves the cost.
16-second window gives clouds and light time to develop; 4K option for big screens.
The only model here that goes to 30 seconds in one clip, with synced audio.
Fastest turnaround and loose, expressive motion — ideal when you'll post the funniest take, not the cleanest.
A pattern to notice: Kling 2.6 and Seedance Mini at ⚡20 cover most everyday jobs, Veo 3.1 is worth the upgrade when the image itself is the point, and Vidu Q4 / Seedance 2.5 exist for length. Grok Imagine wins on iteration speed.
Coming: same-image benchmark
We are preparing a side-by-side benchmark — the same ten images (portraits, products, pets, landscapes) through all six models with public prompts, generation times, credit costs, and the failures included. Until it’s published, we’re deliberately not crowning an overall winner from unrelated showcase clips, and we’d caution you to treat any site that does (including ours, elsewhere) with skepticism. The comparison you can trust today is the one you run yourself: same image, same prompt, two models, one balance.
Compare them yourself — on one balance
That’s the point of img2.video: six models, one interface, one-time credits from $5.90, no subscription. Sign up free, get ⚡15 welcome credits, and A/B your own image across models.
Frequently asked questions
What is the best AI image-to-video model?
There is no single winner — it depends on your image and what you mean by "best". For realism on people, Veo 3.1 leads on our site; for cinematic motion on a budget, Kling 2.6 at ⚡20 is hard to beat; for long 30-second clips, only Seedance 2.5 goes there; for the cheapest usable clip with audio, Seedance Mini. The honest way to decide is to run the same image and prompt through two models and compare — which is exactly what this site lets you do on one credit balance.
Which is better, Kling or Veo?
They trade wins. Kling 2.6 costs less (⚡20 vs ⚡25 at default), renders at 720p, and is strong at prompt adherence and natural motion. Veo 3.1 Fast is the pick when image fidelity matters most — sharper faces, better light, and a 4K option Kling does not offer. For a keepsake portrait we would spend the extra 5 credits on Veo; for testing ten prompt ideas fast, Kling.
What is the best alternative to Kling?
On img2.video you can try Grok Imagine 1.5, Veo 3.1, Vidu Q4, Seedance 2.5, Seedance Mini — plus Kling 2.6 itself — on the same balance without a subscription. Vidu Q4 is the closest "different take" (16s clips, 4K); Seedance Mini is the cheaper route (⚡20 with audio).
Which AI video generator supports multiple models?
img2.video does — six of them behind one interface and one credit balance: Grok Imagine, Kling 2.6, Veo 3.1, Vidu Q4, Seedance 2.5 and Seedance Mini. You switch models per generation; there is no separate subscription per model.
How much does each model cost per video?
At default settings: Kling ⚡20 and Seedance Mini ⚡20, Grok ⚡25, Veo ⚡25, Vidu ⚡30, Seedance 2.5 ⚡65. At the Starter rate (8.25¢/credit) that is $1.65–$5.36 per clip, scaling with duration and resolution. Failed generations refund automatically.
How can I compare AI video models fairly?
Use the same source image, the same prompt, and similar duration. Compare facial stability, prompt adherence, and artifacts — not unrelated showcase clips. We are preparing a same-image benchmark page with public prompts and per-model outputs; until then, treat any site-wide "best model" claim (including ours) with caution.
