The Best AI Image-to-Video Generators in 2026 (Prices, Lengths & Audio Compared)

Search for the "best AI image-to-video generator" in 2026 and you'll find a dozen listicles comparing platforms. But here's the thing those lists skip: nearly every tool you'll try is powered by the same handful of flagship models — Sora, VEO, Kling, Seedance, Hailuo. The real question isn't which website to use. It's which model fits your shot.

So this roundup compares the models themselves: every image-to-video model we run in 2026, from 3-credit drafts to 30-second single takes, with real per-clip costs, clip lengths, resolutions, audio, and what each is genuinely best at. One disclosure up front: we build FlyAIgh, where every model below runs under one account on the same photo. We've kept the comparison honest — every price comes straight from our live model registry (the same numbers the product shows you before you hit generate), and where a competitor model wins, we say so.

Quick answer: best by use case

• Best overall: Seedance 2.0 Pro — 4–15s clips, first+last frame control, up to 9 reference images, native audio, up to native 4K (11.1 credits/sec at 720p).
• Best photoreal 8s clip: VEO 3.1 Quality — the most lifelike motion and camera work, flat 90 credits per 8s clip (180 with sound), up to 4K at no extra cost.
• Best cinematic look with audio: Sora 2 Pro — 17 credits/sec, 4/8/12s, audio included natively.
• Best for faces across repeated takes: Kling V3 — and Kling V3 Omni when you need multi-image reference plus native audio at the same 8 credits/sec.
• Best value workhorse: HappyHorse 1.1 — 6.6 credits/sec (promotional, down from 11), 3–15s, up to 9 reference images.
• Longest single take: Seedance 2.5 — 4–30s with up to 30 reference images (15.3 credits/sec at 720p), or WAN 3.0 — 2–30s at about 4 credits/sec at 720p during its −30% promotion.
• Cheapest drafts: Grok Imagine (3 credits/sec), Hailuo 2.3 Fast (from 11 credits per clip), VEO 3.1 Lite (24 credits per 8s clip).

How we compared them

Five things actually separate these models when you animate a real photo:

• Motion quality — does the movement look physically plausible, or does it smear and morph?
• Identity hold — does the face/product in your photo still look like itself after 5 seconds?
• Control surface — first/last frame, multi-image reference, duration and resolution options.
• Audio — native sound generation, or silent output only.
• Real cost per clip — what you actually pay each attempt, in credits, before any retries.

The budget tier: cheapest per attempt

Grok Imagine — the cheapest way to see a photo move. At 3 credits/second (6s or 10s clips, up to 720p), nothing else comes close on price. The trade-off is control: no first/last frame, no reference images, no resolution above 720p. Best for testing a motion idea before you spend real credits on a flagship, and one of the two video models a free account can run (as a watermarked preview). See Grok Imagine details.

Hailuo 2.3 Fast — the cheap specialist. From 11 credits per clip, this variant does image-to-video and nothing else — and that focus makes it the fastest way to animate a photo in the Hailuo family. It keeps your source image's native aspect ratio, which is either convenient or limiting depending on the shot. The full Hailuo 2.3 (from 18 credits) adds text-to-video and stronger detail.

VEO 3.1 Lite — the budget door into VEO. 24 credits per 8-second clip (720p or 1080p), with first+last frame control that the other two budget picks lack. Motion quality is a step below VEO 3.1 Fast, but for many shots it's 45% of the price of its bigger sibling.

The all-rounders: where most shots should start

Kling V3 — the face keeper. 8 credits/second, 3–15s, 720p/1080p, with first+last frame control. Its calling card is identity: repeated takes of the same person hold together better than on most rivals. Kling V3 Omni costs exactly the same and trades the last-frame slot for multi-image reference (up to 7 images) and native audio — pick V3 for frame-precise control, Omni for reference-driven shots with sound. See Kling details.

HappyHorse 1.1 — the value anomaly. 6.6 credits/second (a promotional cut from 11), 3–15s, 1080p by default, and up to 9 reference images — a control surface that rivals models costing twice as much. If you iterate a lot, this is where the math works best. See HappyHorse details.

Pixverse v6 and C1 — the 6-credit pair. Both run 6 credits/second at 5s or 8s. v6 adds first+last frame control; C1 keeps that and adds up to 4 reference images. Solid, predictable mid-tier output for social content. See Pixverse details.

WAN 2.7 — the 2-second tester. 9 credits/second at 1080p (720p bills at ×0.6), 2–15 seconds. That 2-second floor (shared only with WAN 3.0) is genuinely useful — it's the cheapest possible way to sanity-check a motion before committing. First+last frame plus up to 4 reference images. See WAN 2.7 details.

Vidu Q3 Pro — the compact all-rounder. 8 credits/second at 4s, 5s, or 8s, with first+last frame and up to 7 reference images. A strong pick when your shot lives or dies on reference fidelity at standard social lengths. See Vidu details.

Sora 2 — the affordable cinematic look. 6 credits/second at 4/8/12s with native audio included in the flat rate. The 720p-only ceiling and lack of frame control are real limits, but for atmospheric, film-like motion at mid-tier cost it punches above its price. See Sora details.

The flagship tier: when quality is the brief

Seedance 2.0 Pro — the most complete 15-second model. 4–15 seconds, first+last frame, up to 9 reference images, native audio with a user toggle, seven aspect ratios, and resolution scaling from 480p to native 4K. At 11.1 credits/second (720p basis) it's not cheap, but no other model combines this much control with this much consistency. Seedance 2.0 Fast keeps the entire control surface at 8.9 credits/second (4K instead of native 4K) — the right default for most serious work. See Seedance details.

VEO 3.1 Fast & Quality — the photoreal benchmark. Fixed 8-second clips at 45 and 90 credits respectively, first+last frame, and output up to 4K with no resolution surcharge — unique among the flagships. For natural camera movement and physically believable motion, VEO 3.1 Quality is still the one to beat. One caveat: sound is billed on top on these two tiers, so a clip is 68 (Fast) or 180 (Quality) credits with sound, and 45 or 90 with the sound switch off. See VEO details.

Sora 2 Pro — the cinematic flagship. 17 credits/second at 4/8/12s, 720p or 1080p, with audio natively included. It offers no first/last frame or reference-image control, which makes it a "prompt and trust the model" experience — but when it lands, the look is the most filmic of the group. See Sora details.

Hailuo 2.3 — the physical-motion specialist. From 18 credits per clip (6s or 10s, up to 1080p on the 6s tier). It animates your photo in its native aspect ratio and has a reputation for convincing body and cloth movement — worth a slot in any portrait or fashion bake-off. See Hailuo details.

The 2026 newcomers: long takes, keyframes, and many references

The models added in the second half of 2026 move the limits in three directions: longer single takes, more reference inputs, and sound in more places. These are capability notes, not quality verdicts; run your own photo through them before you commit.

Seedance 2.5 — the longest take with the most references. 4–30 second single takes, first+last frame, up to 30 reference images, and a native audio switch at no extra cost. 15.3 credits/second at 720p; 1080p, 2K and 4K are upscaled from 720p. See Seedance 2.5 details.

WAN 3.0 — the cheaper 30-second option. 2–30 seconds, first+last frame, and up to 10 images, 5 videos and 5 audio clips you can address by name in the prompt ("image 2", "video 1"). 7.9 credits/second at 1080p during a −30% promotion (list 11.3); 720p is half that and 480p a quarter, so a 30-second 720p take is about a quarter of Seedance 2.5's price at 720p. See WAN 3.0 details.

Gemini Omni 1.1 Flash — native 4K with sound always on. 3–10 seconds in 16:9 or 9:16, 360p to native 4K, first+last frame, up to 10 reference images plus 3 short reference videos (not billed). 7.3 credits/second at 720p, with sound included in that price. See Gemini Omni details.

FLUX 3 Video — keyframes on a timeline. Pin up to 10 stills: one opens the shot, two set first and last, three to ten add evenly spaced beats, and the model animates between them. 5–20 seconds, native audio switch at no extra cost, 11.3 credits/second at HD (Draft costs about a third, FHD about 1.7×). See FLUX 3 details.

MiniMax H3 — native 2K. 7.2 credits/second at 2K or about 4.3 at 768p, 5–15 seconds, first+last frame, up to 9 reference images (the first 5 free, then 2 credits each) plus reference video and audio, with stereo sound included. In image-to-video and first+last mode the clip follows your photo's aspect ratio. See MiniMax H3 details.

Vidu Q4 Preview — 12 references, up to 4K. Image-to-video or up to 12 reference images (no text-to-video and no first+last frame), 3–16 seconds, 540p to 4K, 6 credits/second at 720p, and a sound switch at no extra cost. Reference audio must be MP3. See Vidu details.

Side-by-side comparison

HappyHorse 1.0 (15 credits/sec) is still available but superseded by 1.1 — same control surface at less than half the rate, so it didn't earn a row. In the audio column, "switch" means sound you turn on or off at no extra cost, "included" means every clip comes with sound, and a dash means silent output. On per-second models, resolutions above 720p multiply the rate; the two flat-rate exceptions are VEO 3.1 Fast and Quality, which bill the same at 720p, 1080p, and 4K.

How to choose

1. Drafting or testing an idea? Start at the bottom of the price table — Grok Imagine (3/sec), Hailuo 2.3 Fast (from 11/clip), or WAN 2.7's 2-second minimum. Iterate until the motion reads, then re-render the winner on a flagship.
2. Is there a person in the photo? Kling V3 for faces that hold across takes; Kling V3 Omni or Seedance 2.0 when you need multi-image reference to pin identity.
3. Need longer than 15 seconds in one take? Seedance 2.5 or WAN 3.0 (both up to 30s), FLUX 3 Video (20s) or Vidu Q4 Preview (16s). Seedance 2.0, Kling V3, HappyHorse 1.1, MiniMax H3 and WAN 2.7 reach 15s; VEO is always 8s and Sora maxes at 12s.
4. Delivering in 4K? VEO 3.1 Fast/Quality (flat rate at any resolution), or Seedance 2.0 Pro and Gemini Omni 1.1 Flash (native 4K, multiplier applies). Kling V3 Omni and Vidu Q4 Preview have a 4K tier; Seedance 2.5 and 2.0 Fast upscale to 4K; MiniMax H3 is native 2K.
5. Need sound in one pass? Seedance 2.5 and 2.0, WAN 3.0, FLUX 3 Video, Vidu Q4 Preview, Kling V3 and Kling V3 Omni have a sound switch at no extra cost; Gemini Omni 1.1 Flash, MiniMax H3, Sora 2, VEO 3.1 Lite, Grok Imagine, HappyHorse 1.1 and WAN 2.7 always include it; on VEO 3.1 Fast and Quality it is a switch billed on top (68 and 180 credits per clip).
6. Making an ad? Format, length and sound matter more than the leaderboard — see which AI video models fit Facebook and Instagram ads.
