This page lists what one second of AI video costs on every video model you can pick in Morphed today, 34 models in all, with the cost of a 5-second and a 10-second clip and how many of those clips a $9 plan buys. Below that are the official API list prices for Google, Kling, Runway (including the third-party models it resells) and Luma, each checked on the provider's own pricing page on November 4, 2026.
Disclosure: Morphed is our product, so read the first table as our price list rather than a neutral survey. The numbers come straight from the model catalog the app bills from, run through the same cost function that charges your account. Nothing here is a quality ranking; for that, see our best AI video generators roundup.
What is the cheapest and the most expensive AI video per second?
The cheapest video model on Morphed is Grok Imagine Video 1.5 Lite at 480p: 3 credits per second with audio included, so a 5-second clip costs 15 credits and the $9 plan's 650 credits cover 43 of them (216 seconds of video). At 720p the same model costs 4.5 credits per second, or 28 five-second clips per $9 plan.
The most expensive is Seedance 2.0 at 4K, now listed under Legacy: 223 credits per second, so one 5-second clip costs 1,115 credits, more than the $9 plan holds. Among current-generation models the top rate is Seedance 2.5 at 720p, 73 credits per second, which buys one 5-second clip per $9 plan.
That is a 74-fold spread between the cheapest and the priciest second of video in one catalog. Resolution drives most of it: the same model costs 1.5 to 4.4 times more per second at 1080p than at 720p.
On direct APIs, the cheapest official rate we could verify is Grok Imagine Video 1.5 Lite at 480p on Runway's API, $0.02 per second, and the highest is Seedance 2.0 at 4K on the same rate card, $1.50 per second. Same two models, same ends of the range.
How we built this table
We generated the table with a script that reads Morphed's live model catalog and keeps only models that are enabled and shown in the video model picker. Models marked hidden are left out, since they only run behind another model (for example the image-to-video version that kicks in when you attach a start frame). Every clip cost comes from the app's own billing function, including its rounding, and the per-plan counts use the same math as our pricing pages: monthly plan credits divided by the clip cost, rounded down.
Prices are in credits because that is what Morphed charges. The $9 Basic plan includes 650 credits a month; the $29 Pro plan includes 2,000 and the $49 Creator plan 4,500. New subscribers get 30% off their first 3 months on web checkout. See pricing for the full plan list.
AI video cost per second on every current model
Sorted by each model's cheapest tier, from lowest to highest. "Optional, no extra cost" means the model can generate a soundtrack and the rate is the same with or without it. "Optional, paid" means switching audio on adds credits, shown in brackets.

Three things the table does not show:
- Image-to-video uses the same rate on almost every model. Attaching a start frame switches to the model's image-to-video version at the same price, with two exceptions. Luma Ray 3.2 drops to 4.5, 9 and 34.5 credits per second at 540p, 720p and 1080p, and allows 5-second clips only. Grok Imagine Video 1.5 Lite rises slightly, to 3.5, 5 and 20.5.
- Reference modes cost the same per second, plus your inputs. The reference-to-video versions of Gemini Omni Flash 1.1, MiniMax H3, MiniMax H3 Max, WAN 3.0, WAN 3.0 Prime, Seedance 2.5, Kling O3 4K and Happy Horse 1.1 bill the rates above. Seedance and MiniMax H3 reference modes also bill the seconds of any reference video you upload.
- Clips that do not divide evenly round up to the next length the model offers. Veo 3.1 only makes 4, 6 or 8 seconds, so its "5 s clip" is priced at 6 seconds and it cannot make a 10-second clip in one pass.
Older video models still in the picker
These stay selectable under "Legacy" in the model picker because newer versions of the same family exist. They are priced the same way.

What do the official AI video APIs charge per second?
These are list prices from each provider's own pricing page, checked on November 4, 2026. We only included a rate when the provider publishes it in dollars per second, or per clip of a stated length that converts cleanly. Morphed is not in this table because it bills in plan credits, not dollars per second.
| Provider | Model | Official list price | Per second | Billing notes |
|---|---|---|---|---|
| Google (Gemini API) | Gemini Omni Flash 1.1 | $17.50 per 1M video output tokens | About $0.03 (360p), $0.10 (720p), $0.15 (1080p), $0.30 (4K) | Audio included. Google states about $0.10 per second at 720p; other resolutions use Google's published tokens per second. Pay as you go |
| Kling | Kling 3.0 | $0.084 / $0.112 per second at 720p / 1080p without audio; $0.126 / $0.168 with audio | $0.084 to $0.42 | 4K is $0.42 per second. Prepaid packages only, from $500, valid 180 days |
| Kling | Kling 4.0 | $0.157 / $0.235 per second at 720p / 1080p | $0.157 to $0.235 | Clips that take an input video bill extra seconds |
| Runway | Gen-4.5 | 12 credits per second at $0.01 per credit | $0.12 | Credits bought in the developer portal |
| Runway | Gen-4 Turbo | 5 credits per second | $0.05 | Same credit price |
| Runway (reselling Google) | Veo 3.1 | 40 credits per second with audio, 20 without | $0.40 with audio, $0.20 without | Veo 3.1 Fast: $0.15 with audio, $0.10 without |
| Runway (reselling xAI) | Grok Imagine Video 1.5 Lite | 2 / 3 / 14 credits per second at 480p / 720p / 1080p | $0.02 / $0.03 / $0.14 | Plus 1 credit for an image-to-video start frame |
| Runway (reselling ByteDance) | Seedance 2.5 | 20 / 30 / 68 credits per second at 480p / 720p / 1080p | $0.20 / $0.30 / $0.68 | Input and reference video billed on top; 80-credit minimum per clip |
| Runway (reselling ByteDance) | Seedance 2.0 | 14 / 30 / 40 / 150 credits per second at 480p / 720p / 1080p / 4K | $0.14 to $1.50 | 56-credit minimum per clip |

| OpenAI | Sora 2, Sora 2 Pro | Not sold | None | Removed from the API on September 24, 2026 |
Three changes since this post first ran in August matter more than any single rate:
Sora is gone from the API. OpenAI's deprecations page lists the Videos API, sora-2 and sora-2-pro as removed on September 24, 2026, with no replacement named. Any cost model built on Sora 2's per-second price needs a new model.
Veo left the Gemini API. Google's deprecation page shut down the Veo 3.1 preview models on the Gemini API on October 22, 2026 and names Gemini Omni Flash 1.1 as the replacement. Veo 3.1 is still sold on Google Cloud, whose pricing table lists $0.40 for 720p and 1080p with audio, and through resellers such as Runway. Omni Flash 1.1 bills by output tokens rather than seconds, so cost scales with resolution: 360p is about a third of the 720p price, and 4K about three times it.
Resellers now publish the clearest per-second prices. Runway's API rate card lists per-second prices for Veo, Kling, Seedance, Grok Imagine, WAN and MiniMax models next to its own, at a flat $0.01 per credit, which makes it the easiest single place to compare labs. Kling's own API is cheaper for Kling 3.0 at 720p ($0.084 against Runway's $0.09 for Kling 3.0 Standard without audio) but is sold only in prepaid packages from $500 that expire after 180 days. Luma bills Ray 3.2 per clip, and its 10-second clip costs three times its 5-second clip, not twice.
What does production-level 720p video cost from an API?
The lowest pay-as-you-go 720p rate we could verify is Grok Imagine Video 1.5 Lite on Runway's API at $0.03 per second, so a 10-second clip costs $0.30. From a lab's own API, Gemini Omni Flash 1.1 is about $0.10 per second at 720p with sound included, or $1.00 for 10 seconds. Luma Ray 3.2 is $0.30 for a 5-second 720p clip without sound, and Kling 3.0 is $0.084 per second if you can commit $500 up front.
On Morphed, the 720p options run from 4.5 credits per second (Grok Imagine Video 1.5 Lite, audio included) through 6 (MiniMax H3 Max Turbo at 768p), 15 (Gemini Omni Flash 1.1) and 16 (WAN 3.0) to 73 (Seedance 2.5). On the $9 plan that is 28, 21, 8, 8 and 1 five-second clips respectively.
"Production-level" depends on the shot more than the rate card. A model that lands the shot in two tries at 15 credits per second is cheaper than one that needs six tries at 6.
Why the sticker rate is not what you pay
Per-second pricing describes the cost of one successful generation. Retakes are the biggest cost in any real project, and we do not publish an average retake rate because we do not have clean first-party data on it. What we can tell you is how to keep the multiplier down.
Draft at low resolution, finish at high. On FLUX 3 Video, five 20-second drafts at 720p cost 2,500 credits and one 1080p finish costs 840. Five 1080p attempts would cost 4,200 credits for the same learning. Models with a 360p or 480p tier, such as Gemini Omni Flash 1.1, WAN 3.0 and Seedance 2.5, make the gap wider.
Check what audio costs before you switch it on. On Morphed, sound doubles the per-second rate on Veo 3 and Veo 3.1 and on Kling 2.6, and adds 7 to 8 credits per second on Kling V3 Standard and Pro. Every other audio model includes it at the same rate. On Kling's own API, audio raises the 720p rate from $0.084 to $0.126 per second.
Pick on longest clip before price. Veo 3.1 caps a single pass at 8 seconds and Luma Ray 3.2 at 10. WAN 3.0 and Seedance 2.5 reach 30 seconds and FLUX 3 Video 20. Every stitch point in a longer spot is a place where lighting, faces and ambience can drift, and every fix is another paid generation.
Write the prompt for the shot. A prompt that names camera distance, lens, light direction and what the subject does in the last few seconds lands more often than one that describes a mood. Model-specific structure is in our FLUX 3 Video prompts and Hailuo 3 prompts guides.
Should you call the API directly or use a platform?
Going direct is cheaper per second and more expensive per hour. At high volume on one model, the direct rate wins; Kling 3.0 at $0.084 per second is hard to beat if you will spend the $500 package before it expires.
What you take on with direct APIs: a key and billing account per provider, polling for async jobs, retries when a generation fails, storage for outputs, and a UI if anyone else on your team needs to use it.
A platform like Morphed trades a markup for one credit balance across 34 video models, so switching models is a menu choice rather than a new integration. The cons are real: there are no free renders, plan credits reset every month rather than rolling over, and at steady high volume on a single model the direct API costs less. One-off credit packs exist for top-ups, starting at 300 credits for $6.
The pattern most teams land on is a platform for exploring and client work, and a direct API for the one high-volume workflow that has settled.
Does cheap AI video come with a watermark or commercial-use limits?
Free tiers are where the hidden costs sit. Kling's terms say free output may not be used commercially without written permission and must be labelled as made with Kling AI; paid members are exempt. Luma's terms allow commercial use only for output made during a paid subscription. Runway lists "No watermarks" from its Standard plan up.
Morphed has no free renders, so there is no free tier to restrict. Output you make with paid credits is yours to use commercially and Morphed does not add a visible watermark, though some underlying models embed invisible provenance data. For the full comparison of who owns AI output and what each tool allows, see Can you use AI images and videos commercially?.
When is filming it yourself cheaper than generating it?
Sometimes the right spend on AI video is zero.
One hero shot you have the props for. A product on a table by a window, shot on a current phone, costs nothing and takes ten minutes. Generating it at 1080p with audio costs 210 credits for 5 seconds on FLUX 3 Video, and it will not match your real label or finish without reference work.
Minute-long spots with heavy continuity. A 60-second piece on an 8-second model is eight generations before a single retake, plus colour matching across clips that were never rendered together.
A specific real person or place. Reference models are good, and still not reliable enough to deliver your actual storefront or founder for a brand spot.
Where AI video clearly wins on cost: shots that need a drone, a crowd, weather you do not have, or a place you cannot reach. And variant testing. Twelve 10-second 720p variants on Gemini Omni Flash 1.1 cost 1,800 credits on Morphed, which fits in the $29 plan, or about $12 on Google's API.
What to do with this
Pick the longest clip you need first, then the resolution, then compare rates inside that shortlist. Draft at the lowest tier the model offers and only pay the 1080p or 4K rate once the shot works.
