Los mejores generadores de vídeo con IA para marketing en 2026

Marketers who have never opened an editing timeline can now type a script and get back an ad-ready video with voiceover and music. The tool also adds captions. Wyzowl's 2026 survey quantifies how fast this shifted: 63% of video marketers have used AI video tools, up from 51% in 2025. This guide compares the best Generadores de vídeo con IA para marketing por calidad de resultado, opciones de avatar, precio y uso comercial, basándonos en las valoraciones de G2's AI video category.

What makes the best AI video generator for marketing

A marketer with no editing background needs different things from an AI video tool than a filmmaker does. Six criteria separate the tools worth paying for:

• Calidad de texto a vídeo: The tool should turn a prompt or script into usable footage without dozens of retries. Prompt adherence is uneven; even top models misread roughly one prompt in four.
• Avatares y voces en off: If you don't want to appear on camera, you need stock avatars or a digital twin, plus AI voiceover in the languages your campaigns run in.
• Commercial use for paid ads: Algunas plataformas restringen la publicidad de pago incluso en los planes de pago. Revisa la licencia antes de destinar presupuesto a medios.
• Transparent pricing: A credit buys wildly different amounts of output depending on the model you pick. Compare cost per finished video rather than sticker price.
• Ad formats: Las redes de pago necesitan salida en 9:16, 1:1 y 16:9. No todos los modelos admiten vídeo vertical.
• Facilidad para quien no edita: Look for template libraries and script writers with chat-based interfaces rather than timeline editors.

The best AI video generators for marketing at a glance

Here is how these AI video generators for marketing compare on positioning and commercial use, plus entry price:

Best all-in-one platform for script-to-finished-ad video

OpenArt combina generación, personajes persistentes, voz en off y dirección multiescena en un solo espacio de trabajo. Es ideal para marketers que quieren pasar del guion al anuncio final sin tener que combinar varias suscripciones.

OpenArt

Running separate subscriptions for image and video plus voiceover means rebuilding your spokesperson in each one. OpenArt aggregates 100+ AI models for image, video, audio, and 3D under one subscription, including Veo 3.1, Kling 3.0 Omni, and Seedance 2.5.

OpenArt Director crea vídeos multiescena de hasta 5 minutos con los mismos personajes y entornos en cada plano, junto con voces coincidentes. Utiliza nueve plantillas, incluidas Cortometraje, Anuncios UGC y Videoclip. El Creador de personajes guarda un personaje persistente en tu biblioteca, lo que reduce la deriva de identidad entre generaciones.

OpenArt también incluye voz en off en más de 30 idiomas y clonación de voz. Genera música y efectos de sonido, con sincronización labial disponible para las voces en off. Puedes exportar el audio en WAV o MP3.

• Pros: One subscription replaces separate tools for image, video, and audio.
• Also strong: OpenArt Director generates finished multi-scene ads sin unión manual.
• Contras: Official documentation does not publish per-feature credit costs. Base plan credits do not roll over month to month.
• Pricing: Essential cuesta 14 $/mes por 4.000 créditos sin uso comercial. Advanced cuesta 29 $/mes por 12.000 créditos y añade uso comercial más entrenamiento de LoRA; Infinite cuesta 56 $/mes y Wonder 240 $/mes para un mayor volumen.
• Ideal para: Choose OpenArt if you want ads and social clips, plus product videos and voiceover, from one tool instead of three subscriptions.

Best for AI avatars and talking-head videos

If you want a spokesperson video without filming anyone, avatar platforms generate a presenter from a photo, a short recording, or a stock library.

HeyGen

HeyGen tiene una valoración de 4,8/5 en G2 con 1.931 reseñas. La plataforma ofrece Avatar IV y traducción de vídeo, promocionada en más de 175 idiomas. El centro de ayuda de HeyGen enumera 77 idiomas concretos con variantes regionales.

• Pros: Independent avatar testing found that its avatars have better lip-sync and more natural head movement than Synthesia's, which helps them feel less stiff in ad creative.
• Contras: Avatar IV consumes 20 credits per minute, so premium output can use credits quickly.
• Pricing: The free plan gives 3 watermarked videos a month, Creator costs $29/mo, Pro adds 4K at $49/mo, and Business runs $149/mo.
• Ideal para: Choose HeyGen for talking-head ads o vídeos de portavoces multilingües si prefieres no aparecer en cámara. HeyGen afirma que "eres el dueño de los vídeos que generas y puedes usarlos en anuncios, formación y trabajos para clientes con planes de pago".

Synthesia

Synthesia offers 125+ stock avatars on its Starter plan, rising to 240+ on Enterprise, and supports 160+ languages. It is the stronger pick for training and internal video; avatar comparison reviewers describe its avatars as "corporate presenters, which suits training but feels stiff in ads and social content."

• Pros: Synthesia indemnifies customers for IP and stock-avatar likeness claims, a protection the research did not identify on other avatar platforms.
• Contras: Synthesia's acceptable use policy requires written consent for paid or promoted social advertising with stock avatars on any plan, covering Facebook, Instagram, YouTube, TikTok, and programmatic ads. Synthesia caps exports at 1080p.
• Pricing: El plan gratuito permite 10 minutos al mes sin descargas, Starter cuesta 19 $/mes y Creator 89 $/mes.
• Ideal para: Use Synthesia for product explainers and onboarding. It also fits organic social, but not paid ad campaigns with stock avatars.

D-ID

D-ID provides a low-cost entry into commercial avatar video. Its Pro plan includes 15 minutes per month and three personal avatars.

• Pros: El plan Pro por 16 $/mes incluye uso comercial, y D-ID lo dice sin rodeos: «Eres libre de usar tus vídeos en anuncios, marketing, contenido empresarial y mucho más.»
• Contras: Los créditos caducan cada mes y el plan Lite solo permite uso personal.
• Pricing: Lite runs $4.70/mo, Pro $16/mo, and Advanced $108/mo with 100 minutes a month.
• Ideal para: Pick D-ID on a tight budget to test commercial avatar video before committing to a bigger plan.

Ideal para anuncios sociales de formato corto y UGC

UGC-style ads mimic creator content: a person holds your product and talks to the camera in footage that looks like a phone video. Creatify builds this format from a product URL.

Creatify

Creatify holds a 4.8/5 on G2 across 1,654 reviews, with G2 labeling it best for "UGC-style ad creative generation at scale." Paste a product URL and it generates scripted actor videos; Batch Mode generates up to 50 variations at once, and the Pro plan adds an AI Media Buyer.

• Pros: Pro te ofrece más de 1500 actores con IA, más de 75 idiomas con sincronización labial y un guionista con IA integrado.
• Contras: Creatify reviewers report lip-sync errors that force re-generations, which consume credits. Creatify adds a watermark to free exports.
• Pricing: The free plan includes 10 credits, Starter costs $39/mo for 100 credits, and Pro $99/mo.
• Ideal para: Choose Creatify if you need dozens of ad variations per week for paid social testing.

Best for text-to-video and cinematic generation

These engines turn a written prompt into original footage. You describe the subject, action, camera movement, and lighting; the model generates a clip, typically 5 to 15 seconds, in two to five minutes. They suit product visualizations and brand films rather than talking-head ads, since a May 2026 benchmark found all nine text-to-video models tested fail at close-up talking heads with reliable lip-sync.

Runway

Runway's Gen-4.5 generates 2–10 second clips at 720p and "scored the highest in blind preference leaderboards against Google and OpenAI models," according to Zapier's May 2026 testing. Aleph 2.0 adds video editing through Runway's Edit Studio.

• Pros: Runway permits commercial use on every plan, including Free, with "product advertising" expressly listed as a permitted use.
• Contras: The 10-second clip cap limits longer workflows, Runway generates no audio, and Zapier flagged a "steep learning curve."
• Pricing: The free plan gives 125 one-time watermarked credits; Standard costs $12/mo, Pro $28/mo, and Max $76/mo with annual billing.
• Ideal para: Pick Runway if you want cinematic generation and detailed editing control.

Google Veo 3.1

Veo 3.1 generates 8-second clips at up to 4K with native synchronized audio, including dialogue and ambient sound. PCMag's June 2026 review named it Best Overall at 4.0/5, and Tom's Guide awards gave Veo its Best AI video generator award in 2025.

• Pros: Zapier's Veo testing found "strong prompt adherence" and "great realism," and scene extension can chain clips to roughly 148 seconds.
• Contras: Like other cinematic engines, Veo cannot reliably maintain a recurring character across clips. Google's consumer terms do not expressly address paid advertising use, which leaves ad campaigns on uncertain footing.
• Pricing: Google AI Pro costs $19.99/mo with 1,000 Flow credits, and the API charges $0.40/second for Veo 3.1 Standard with audio at 720p/1080p.
• Ideal para: Use Veo 3.1 for photorealistic single clips where native audio matters.

Kling AI

Kling 3.0 Omni generates clips up to 15 seconds, and Kling 2.6 adds native audio at 10 credits per second in professional mode. TechRadar's March 2026 testing found Kling easier to use than Runway.

• Pros: Kling's promotional entry price undercuts Runway's and Pika's, and Kling 2.6 extensions reach 3 minutes total.
• Contras: Promotional prices apply only to the first subscription ($6.99 renews at $8.80 on Standard), and non-members must display a Kling watermark.
• Pricing: Standard costs $6.99/mo promo for 660 credits, Pro costs $25.99/mo promo, and every paid membership includes commercial use.
• Ideal para: Pick Kling for cheap cinematic B-roll and product motion shots.

Ideal para producción rápida basada en plantillas

Template platforms skip generation from scratch: paste a blog URL or upload images, and the tool assembles stock footage and voiceover, then adds captions to a finished video.

InVideo AI

InVideo's paid plans include licensed stock from iStock and Storyblocks, plus access to 200+ image, video, audio, and music models. These include Seedance 2.0, Veo 3.1, and Kling 3.0. InVideo supports URL, blog, and image-to-video on paid plans.

• Pros: InVideo grants perpetual, irrevocable commercial use that survives cancellation.
• Contras: Credits do not carry forward. In a hands-on practitioner test, Marc Andrews clocked a blog-to-video job at 20–35 minutes, about three times longer than Pictory.
• Pricing: Plus costs $17/mo for 75 credits, Max $85/mo, and Generative $170/mo with annual billing.
• Ideal para: Use InVideo to repurpose blogs and long-form content into social video with stock footage.

Pictory

Pictory converts a URL or script into a captioned, voiced video in 8 to 12 minutes, drawing on up to 18M stock clips from Getty Images and Storyblocks. In Marc Andrews' comparison, he found "the AI picks sensible clips about 75% of the time" with "clean subtitles, relevant stock footage, and a natural-sounding AI voiceover."

• Pros: Pictory finished the tested workflow faster than InVideo and includes ElevenLabs voiceover integration.
• Contras: URL import handles HTML sources only (no PDF, Word, or Google Docs), and Pictory offers no generative AI models, so it assembles the videos from stock.
• Pricing: Starter costs $25/mo annual for 200 video minutes, and Professional $35/mo annual.
• Ideal para: Choose Pictory if you turn articles into YouTube and LinkedIn videos on a schedule.

How text-to-video works and how to make your first marketing video

Text-to-video models learn patterns from videos that researchers paired with written descriptions. The models generate fresh frames matching your description rather than pulling existing footage from a library. Generating each frame costs computing power, which is why clips run seconds rather than minutes.

The model reads your wording slightly differently on each run. Expect to generate again with a sharper prompt. Your first video takes six steps:

1. Pick your tool by output type. For a talking-head ad, pick an avatar platform; for product visualization, a cinematic engine; for a multi-scene ad with a recurring character, OpenArt's Director.
2. Write the script or prompt. Most platforms include an AI script writer; InVideo and Creatify build one in. For cinematic prompts, describe subject, action, camera movement, and lighting. Leave on-screen text out of the prompt entirely; the Kompozy benchmark found, "No model in 2026 reliably renders text within a generated scene."
3. Choose your avatar and voice. Pick a stock avatar or generate one from a photo. Then choose a preset voice or clone your own from a short sample. For multilingual campaigns, HeyGen translates a single video into up to 10 languages simultaneously, and Synthesia's documentation lists dubbing in 139 languages.
4. Generate. Expect 2 to 5 minutes per clip, and plan for iteration, since even strong models miss prompt details on the first pass.
5. Editar. Trim clips and add captions, then composite any on-screen text in post and apply brand colors and logo. Of the marketers in the Wistia 2026 survey, 69% use AI for captioning.
6. Export in the right aspect ratio. Use 9:16 for TikTok and Reels; the same format works for YouTube Shorts. Use 1:1 for feeds. Choose 16:9 for YouTube and pre-roll.

Top marketing use cases

Marketers use these tools across the funnel:

• Video ads: In IAB's 2026 survey, 360 buyers projected that advertisers would build one-third of ad assets with GenAI in 2026, rising to 43% by 2027.
• Short-form social clips: HubSpot's 2026 report found short-form video delivers the highest media-format ROI at 48.6%.
• Product demos: Generate product-in-use footage without a shoot.
• UGC-style creative: Script-to-actor platforms generate creator-style testimonials at volume.
• Repurposing long-form content: Blog-to-video tools turn existing articles into social clips in minutes.
• A/B testing variations: Creatify's Batch Mode generates 50 variations at once; IAB's 2025 report found 42% of GenAI creative use goes to audience versioning.
• Image and URL-to-video: Animate product photos or convert a landing page into an ad without writing a script.

Commercial use and licensing for AI video

You can run AI-generated video in paid ads, but the license depends on the platform and the plan. Check the plan and copyright status first. Then confirm the disclosure requirements.

Licensing thresholds vary by tool

Runway permits commercial use on every plan, including Free. HeyGen, D-ID, Kling, Pika, and Luma require a paid plan. Synthesia's stock-avatar restriction on paid advertising is the most consequential constraint in the category; Synthesia exempts custom avatars of your own likeness.

On OpenArt, commercial use starts on the Advanced plan, and you own what you generate. OpenArt keeps creations private by default and includes a CopySight-powered IP Safety Check for risk analysis. Paid plans remove vendor watermarks on most of these tools, though Luma keeps its free-plan watermarks even after you upgrade. The ad platforms and state law set the labeling obligations.

Copyright protection is limited

Current U.S. law does not protect material that an AI system generates without sufficient human authorship, and platforms acknowledge this in their terms. Pika's ToS warns "Outputs might not qualify for copyright or other legal protections under applicable law." You can use the content commercially, but you may not be able to stop others from copying it.

Disclosure is now a compliance requirement

TikTok mandates an AI-content disclaimer. Meta automatically labels detected AI media, while Google provides AI disclosure controls and requires labels in specified campaign or jurisdictional contexts. New York's disclosure law adds a separate legal requirement for synthetic performers. Plan the disclosure while you concept the ad.

• TikTok mandates an ad disclaimer reading "This ad contains AI-generated content."
• Meta automatically detects third-party AI media in ads and labels it.
• Google automatically adds disclosure when advertisers use its own GenAI tools. It requires disclosure for election ads with qualifying synthetic content and visible overlays in specified jurisdictions.
• New York's Synthetic Performer Disclosure Law, effective June 2026, fines undisclosed synthetic performers $1,000 for a first violation and $5,000 for each subsequent one.

Other AI video generators worth trying

Several tools fall short of a category win but fit specific jobs:

• Canva Magic Media: Pick it if your team already designs in Canva; clips run 4–5 seconds, and commercial use is permitted on the free plan.
• Luma Dream Machine: Use it for quick image-to-video motion tests, but its free-plan watermarks stay even after you upgrade.
• Pika: Choose Pika for cheap short clips, with paid plans starting at $8/mo.
• Lumen5: Use Lumen5 for simple text-to-video at $19/mo, though Basic caps output at 720p.
• Arcads: Consider Arcads for UGC actor libraries at scale; it offers 1,000+ actors and publishes no pricing. Third-party estimates start around $110/mo.

¿Qué generador de vídeo con IA deberías usar?

Match one of these AI video generators for marketing to your role, budget, and primary output:

• Solo creator on a budget: Start with Kling at $6.99/mo if you only need short cinematic clips, since every paid Kling membership includes commercial use. OpenArt Essential at $14/mo buys 4,000 credits across 100+ models but no commercial use, so budget for Advanced once you monetize.
• Small business running its own ads: InVideo Plus at $17/mo annual works if your videos come from existing blog content. OpenArt Advanced at $29/mo covers commercial use, 12,000 credits, avatars, voiceover, and Director's UGC Ads template in one subscription.
• Performance marketer testing paid creative: Creatify's Batch Mode and AI Media Buyer suit high-volume Meta and TikTok testing at $39–99/mo.
• Agency or team: HeyGen Business ($149/mo) supports videos up to 60 minutes and exports up to 4K. OpenArt's persistent character library reduces identity drift for a client's brand spokesperson across campaigns.

OpenArt's free trial gives you 40 credits over 7 days with no credit card required. You can test video generation and Character Builder, then try voiceover before picking a plan. Separate from the trial, OpenArt provides ongoing basic image generations through daily free credits.

FAQ

Licensing, free plans, and no-camera workflows come up most often.

Can I make marketing videos with no editing experience?

You can. Template platforms like InVideo and Pictory assemble finished videos from a URL or script. Avatar tools generate a presenter from text, while OpenArt's One-Click Story turns an idea into a roughly 1-minute video with motion, music, and a narrative arc.

Are free plans good enough for marketing?

Free plans work for learning, but they rarely support paid campaigns. Only Runway, Canva, and Adobe Firefly permit commercial use on their free plans, and each limits output: Runway watermarks free exports, and Canva caps AI clips at 4–5 seconds.

Can I copyright AI video and use it in paid ads?

You can use it in ads on plans that include commercial use, but current U.S. law does not protect material that an AI system generates without sufficient human authorship. Plan for disclosure on TikTok and Meta before launch, then check Google's campaign and jurisdiction-specific requirements.

How do I make videos without appearing on camera?

Use stock avatars, including the 125+ that Synthesia offers on Starter, or build a fictional persona with OpenArt's Character Builder. Pair the character with a cloned or preset voice.

Which tool is best for short-form social ads?

Creatify specializes in UGC-style short-form ads from a product URL.

Can I turn a blog post, URL, or image into a video?

You can do all three. Pictory and Lumen5 convert URLs and articles into stock-footage videos. InVideo handles URL and blog workflows on paid plans, along with image-to-video. Image-to-video generation is also standard on cinematic platforms including Runway.
