The short answer
- The best image to video AI for ads in 2026 is Runway for control, Kling 4.0 and Seedance 2.5 for long polished clips, and PixVerse V6 or Grok Imagine video for the lowest cost per second.
- Clip length now reaches 30 seconds on Kling 4.0 and Seedance 2.5 and 15 seconds on PixVerse, Gemini Omni Flash and Grok Imagine.
- Per-second prices range from $0.02 (Grok Imagine 1.5 Lite) to $0.20 (Seedance 2.5) in the vendor listings below, so a 10 second clip costs from $0.20 to $2.00.
- No model keeps small label text perfectly through motion. Check every frame of the product before it runs.
How these were ranked
Image to video means you supply a still, such as a product shot or a generated image, and the model animates it. For ads the things that matter are clip length, whether you can pin the first and last frame, how many reference images it accepts, whether it makes sound, the price per second, and how much ad-specific tooling sits on top. The ranking below weighs those. Prices and specs are as listed by each vendor, or in Runway's API model directory where noted, on November 9, 2026.
| Tool | Clip length | Resolution | Listed price | Audio |
|---|---|---|---|---|
| Runway | Varies by model | Up to 4K upscaling on Pro and Max | Standard $12/mo billed annually, Pro $28, Max $76 | Yes, by model |
| Kling 4.0 | 3 to 30 seconds | 720p or 1080p | From $0.157/sec in Runway's API listing | By model |
| Seedance 2.5 | Up to 30 seconds | 480p, 720p, 1080p | From $0.20/sec in Runway's API listing | Yes, with audio references |
| Gemini Omni Flash | 3 to 15 seconds | 360p to 4K (Runway listing) | From $0.02/sec in Runway's API listing | Native audio |
| PixVerse V6 | 1 to 15 seconds | 360p to 1080p | $0.040/sec at 720p, $0.080/sec at 1080p | Optional |
| Grok Imagine video | Up to 15 seconds | 480p, 720p, 1080p | 1.5 from $0.08/sec, 1.5 Lite from $0.02/sec | Lip-synced speech |
| Akool | Depends on model | Up to 1080p on Starter, higher above | Plans from $12/seat/mo billed yearly | By model |
The ranked list
1. Runway: best for control and ad workflow
Runway sells the broadest set of controls around image-to-video, and its developer docs list product-ad recipes: Product Ad, Product Swap, Product UGC and Multi-Shot Video, plus an Ad Localization image recipe. Its pricing page lists a Standard plan at $12 a month billed annually ($15 monthly) with 625 credits, which Runway equates to 52 seconds of Gen-4.5 video. Pro is $28 a month billed annually with 2,250 credits, and Max is $76 with 9,500 credits. Higher plans add 4K video upscaling. Runway also lists a new Runway Ads feature for generating, testing and publishing ads.
Best for: teams that want one place for generation, editing and product-ad templates.
2. Kling 4.0: best for long, polished clips
Runway's model directory lists Kling 4.0 as 720p or 1080p video for 3 to 30 seconds from text, frames, image and video references, or an edit of a source video, from $0.157 per second. Kling 4.0 Flash, a faster 720p version, lists 3 to 20 seconds from $0.094 per second. Runway's own pricing page notes 25% off Kling 4.0 generations until November 30.
Best for: a single longer take where the product stays on screen. Read the Kling review for results.
3. Seedance 2.5: best for reference-heavy cinematic shots
ByteDance's Seedance 2.5 is listed for cinematic video up to 30 seconds at 480p, 720p and 1080p, with a large reference budget for images, videos and audio, from $0.20 per second. Seedance 2.0 is listed from $0.14 per second. It is also available inside PixVerse and Akool.
Best for: complex scenes where you want to feed several references and keep a look consistent.
4. Gemini Omni Flash: best Google option
Google's Gemini API documentation points video generation to Gemini Omni Flash (gemini-omni-1.2-flash). It makes 3 to 15 second videos with native audio from text, image and video inputs, with character consistency across up to 6 reference images, and supports multi-turn editing and extension. Google shut down the Veo 3.1 Preview in the Gemini API on October 22, 2026 and points users to Omni Flash or to the Veo 3.1 GA models on its enterprise agent platform.
Best for: developers who already build on the Gemini API and want audio built in.
5. PixVerse V6: best low-cost clip generator
PixVerse V6 runs 1 to 15 seconds up to 1080p at $0.040 per second at 720p and $0.080 at 1080p without audio, per its API pricing page. It adds first and last frame, multi-subject image references, lip sync and a Video Remake Agent for recreating a reference ad's pacing. Details are in the PixVerse review.
Best for: high-volume testing at a low price per attempt.
6. Grok Imagine video: best for cheap clips with speech
xAI's docs list grok-imagine-video-1.5 from $0.08 per second with native 1080p, lip-synced speech, up to 14 reference images and pinned frames. The 1.5 Lite model is listed from $0.02 per second with text or image to video, speech and up to 15 seconds at up to 1080p. More in Grok Imagine video.
Best for: the cheapest drafts, and talking-product clips.
7. Akool: best single account for many models
Akool's model hub reaches Seedance, Kling, Wan and others behind one credit balance, plus avatar and translation tools. Plans start at $12 per seat per month billed yearly. The lower plans list a personal license, so check terms before paid use. See the Akool review.
Best for: people-led ads and localization more than pure product motion.
What a 10 second clip costs
Using each vendor's lowest listed per-second rate for a 10 second clip, before any plan discounts or retries:
| Model | Listed rate | 10 second clip |
|---|---|---|
| Grok Imagine video 1.5 Lite | $0.02/sec | $0.20 |
| Gemini Omni 1.2 Flash | $0.02/sec | $0.20 |
| PixVerse V6 at 720p | $0.040/sec | $0.40 |
| Grok Imagine video 1.5 | $0.08/sec | $0.80 |
| Seedance 2.0 | $0.14/sec | $1.40 |
| Kling 4.0 | $0.157/sec | $1.57 |
| Seedance 2.5 | $0.20/sec | $2.00 |
Plan on three to six attempts per keeper. A 30 second ad built from three clips that each need four attempts is twelve generations, which is about $2.40 on the cheapest tier and $24 on the most expensive one.
How to get a usable ad clip from a still
- Start with a clean image. High resolution, product fully in frame, even light, and room around it for motion.
- Make the still at the final ratio. Generate it at 9:16 or 4:5 so the model does not crop. Image models such as Nano Banana 2 and GPT Image 2 produce stills at placement sizes.
- Describe one motion. "Slow push in, steam rises, background softly blurs" works better than five actions.
- Pin the end frame if the tool allows. It keeps the product from drifting into something else.
- Check the label frame by frame. Discard any clip where text melts, even if the motion is good.
- Add the hook, captions and offer in editing. Do not ask the video model to render text.

For control and a full editing suite, Runway. For long, polished clips, Kling 4.0 and Seedance 2.5. For the lowest cost per second, PixVerse V6 and Grok Imagine video 1.5 Lite. The right pick depends on clip length, how many reference images you need and how many variants you will test.
What is the cheapest image to video generator?
Among the tools listed here, xAI lists Grok Imagine video 1.5 Lite from $0.02 per second, and Google's Gemini Omni 1.2 Flash is listed from $0.02 per second in Runway's model directory. PixVerse V6 is $0.040 per second at 720p on its API pricing page. A 10 second clip at $0.02 per second is $0.20.
How long can an AI image to video clip be?
It varies by model. PixVerse V6 runs 1 to 15 seconds, Grok Imagine video 1.5 Lite and Gemini Omni Flash run to 15 seconds, Kling 4.0 lists 3 to 30 seconds and Seedance 2.5 lists up to 30 seconds. Most ads are built from several 5 to 10 second clips cut together.
Can image to video AI keep my product accurate?
Not reliably. The model animates your photo but can distort labels, logos and small text during motion. Use a clean, high-resolution product image, keep the camera move simple, and check every frame of the label before the clip runs as an ad.
What image should I upload for image to video?
Upload a sharp, well-lit image at the highest resolution you have, with the product fully in frame and space around it for motion. Match the aspect ratio of the placement, such as 9:16 for Stories and Reels. Avoid busy backgrounds and text that must stay readable.
Do I need to add sound to image to video ads?
Most short-form ads need sound or captions. Several models now generate audio with the clip, including Gemini Omni Flash, Grok Imagine video and PixVerse with its audio option. Check that the speech or music fits your script before you publish.
