Picking an AI text to video generator gets expensive quickly, because the plan price tells you very little about how much usable video you will get. Almost every tool now sells credits. The same subscription can burn them 5 times faster on one model than on another and you will generally throw away a few attempts before one clip is worth keeping. So two plans at a similar price can leave you with very different amounts of footage at the end of the month.

My short answer: start with Google Veo 3.1 inside Flow if you want original clips with sound, move to Runway when you need to direct the motion, use Seedance 2.5 when one shot has to run up to 30 seconds and pick InVideo AI when you need a finished video with a script, voiceover and captions instead of raw footage. Then compare the plans by seconds of video they buy, which is the number that decides your real cost.

These are the main recommendations by the job each one does:

  • Google Veo 3.1 in Flow for polished 8-second clips with native sound, with the faster Gemini Omni Flash model on the same credits.
  • Runway for shots you want to art-direct and drop into a proper edit.
  • Seedance 2.5 for one continuous take of up to 30 seconds.
  • Kling AI and MiniMax Hailuo H3 for the cheapest paid entry into 15-second clips with sound.
  • InVideo AI for a complete marketing or YouTube video built from a prompt.

AI Text to Video Generators Compared

The first 5 rows create footage from a prompt. InVideo AI sits in the last row because it builds a whole video around that footage, and several of these models run inside it. Prices below are for monthly billing on the cheapest paid plan that includes the model in 2026.

If you are still unsure which branch you are in, this is the order I’d think in: do you need raw footage you will edit, or a video you can publish as it comes out?

Best AI Text to Video Generators

These 5 models create the footage itself. None of them is the winner for every job, so each entry says what it is good at, what it costs per second and the catch you will hit first.

Google Veo 3.1

Veo 3.1 is the model I’d start most people on, because it gives the most polished clip for the money inside a tool that is easy to learn. It generates 4, 6 or 8-second clips at 24 frames per second with native audio, so dialogue, effects and ambience come out of the same pass as the picture. 1080p and 4K are available on 8-second clips, and a Veo 3.1 clip can be extended 7 seconds at a time up to 148 seconds.

Google Veo 3.1 in Flow (Google AI Pro)

  • Veo 3.1 Lite, Fast and Quality plus Gemini Omni Flash in one credit pool
  • 1,000 Flow credits a month on Google AI Pro, plus 50 free credits a day
  • Native audio, 4 to 8-second clips, 1080p and 4K on 8-second clips
  • Clip extension up to 148 seconds

The thing to understand is the credit math. On Google AI Pro, a Veo 3.1 Quality clip costs 100 Flow credits, Veo 3.1 Fast costs 20 and Veo 3.1 Lite costs 10, so the same 1,000 monthly credits buy 10 Quality clips or 50 Fast ones. Gemini Omni Flash, which Google now treats as its default video model, costs 7 to 15 credits for a 4 to 10-second 720p clip, and editing an existing clip with it costs 40.

I’d draft in Omni Flash or Veo 3.1 Fast and spend Quality credits only on the shot you already know works. That habit alone stretches a Pro plan about 5 times further.

Why it fits:

  • 50 free Flow credits every day, with or without a subscription.
  • Dialogue, effects and ambience generated in the same pass as the picture.
  • One credit pool for a cheap drafting model and a high-quality finishing model.

Watch out for:

  • 8 seconds is the longest single Veo 3.1 generation.
  • Quality clips drain a Pro plan in 10 generations.
  • Gemini API usage is billed separately from the Google AI subscription.

Runway

Runway is the one for people who already know the shot they want. Its current model, Gen-4.5, generates 5 or 10-second clips, and the tools around it (keyframes, image-to-video and video-to-video) assume you will iterate and then cut the result into a timeline. Pro and Max plans also list Seedance 2.5 and Kling 3.0 among the models you can run with the same credits.

Runway Standard

  • 625 credits a month, enough for 52 seconds of Gen-4.5
  • Gen-4.5 at 12 credits per second, in 5 or 10-second clips
  • 125 one-time credits on the free plan
  • $12 a month when billed annually

Gen-4.5 costs 12 credits a second, so a 10-second clip takes 120 credits and Standard’s 625 credits cover about 5 of them. If you work this way every week, the $35 Pro plan with 2,250 credits (187 seconds of Gen-4.5) is the more realistic starting point.

Why it fits:

  • Strong control tools for directed, edit-ready shots.
  • Clear credit-to-seconds figures on every plan.
  • Third-party models such as Seedance 2.5 on the Pro and Max plans.

Watch out for:

  • 52 seconds of Gen-4.5 a month on Standard is thin once you retry.
  • 10 seconds is the longest Gen-4.5 clip.
  • Standard and Pro credits reset every billing cycle; only Max rolls them over, for 1 month.

Kling AI

Kling AI is Kuaishou’s generator and the cheapest paid way into longer clips with sound. Kling 3.0 makes clips of up to 15 seconds with native audio, and Kling 4.0, which opened to early-access users on September 28, 2026, raises that to 30 seconds with 4K output as it launches fully in October.

Kling AI Standard

  • 660 credits a month
  • Kling 3.0 clips up to 15 seconds with native audio
  • 12 credits a second at 1080p with sound, 6 at 720p without
  • Kling 4.0 rolling out with clips up to 30 seconds
From $10/mo

Sound changes the price more than resolution does here. A 5-second Kling 3.0 clip at 1080p with native audio costs 60 credits, while the same length at 720p without audio costs 30. Standard’s 660 credits therefore buy 55 seconds of the first kind or 110 seconds of the second, so it is wise to switch audio on only for the shots that need it.

Why it fits:

  • The lowest entry price here for 15-second clips with sound.
  • Separate rates for sound and resolution, so you can draft cheaply.
  • Kling 4.0 brings 30-second clips to the same app.

Watch out for:

  • The free Basic plan has no regular daily credits; Kling hands daily credits to subscribers during events.
  • Kling 4.0 credit costs aren’t published yet.
  • Standard’s 660 credits run out in under a minute of 1080p video with sound.

MiniMax Hailuo H3

H3 is MiniMax’s video model, launched on July 31, 2026 and sold through the Hailuo app. It makes clips of up to 15 seconds at 2K with native stereo sound, and it takes text, image, video and audio references in one request. That reference stack is the practical answer to character drift: you show the model the face and the voice instead of describing them again in every prompt. If you build those reference images first, my AI image generator roundup covers the tools for that step.

Hailuo Standard (MiniMax H3)

  • 1,000 credits a month, about 84 seconds of H3 at 2K
  • Clips of 4 to 15 seconds at 768p or 2K
  • Native stereo audio for voice, effects and music
  • Text, image, video and audio references in one generation

Hailuo’s Standard plan lists at $14.99 a month and is discounted to $10.50 right now. At about 12 credits a second for 2K, its 1,000 credits work out to roughly 84 seconds of video, which is more footage than the entry plans of Runway or Kling buy. MiniMax’s launch post also promised open weights for H3, so check that status before you plan a self-hosted pipeline around it.

Why it fits:

  • Up to 15 seconds at 2K with sound in one pass.
  • References for faces, motion and voice in the same request.
  • About 84 seconds of 2K video on the entry plan.

Watch out for:

  • The free tier is a one-time trial grant.
  • 15 seconds is a hard ceiling per clip.
  • The $10.50 price is a discount on a $14.99 list price.

Seedance 2.5

Seedance 2.5 is ByteDance’s audio and video model, and its headline is length. It generates up to 30 seconds in a single take, and you can extend that take twice. It accepts up to 30 images, 10 video clips and 10 audio clips as references, which makes it the model I’d reach for when a short story has a beginning, a middle and an end.

Seedance 2.5

  • Up to 30 seconds in one generation, extendable twice
  • Sound and picture generated together
  • Up to 30 image, 10 video and 10 audio references
  • Available in Dreamina, InVideo AI Pro and Runway Pro

ByteDance doesn’t sell Seedance on its own plan, so you pay for it through a host. Dreamina is ByteDance’s own creator app, and its July rollout named subscribers aged 16 and over in Europe, Asia, the Middle East and South America. Readers in the US will find it easier to use through InVideo AI Pro, where a 5-second 720p clip costs about 56 credits, or through Runway’s Pro and Max plans.

Why it fits:

  • 30-second single takes with no stitching.
  • A large reference allowance for multi-shot stories.
  • Several hosts, so you can use it inside a tool you already pay for.

Watch out for:

  • No direct price; the cost depends on the host’s credits.
  • Dreamina’s rollout doesn’t name the US.
  • InVideo’s $9 Basic plan can’t run it.

Open-Weights Video Models

If you have a capable GPU and want generation with no per-clip bill, two families publish their weights. Both trail the hosted models above on polish, and both need you to read the license before client work.

  • Wan 2.2 from Alibaba is the newest Wan release with open weights, under Apache 2.0. Wan 3.0, which reaches 30 seconds at 1080p, is API-only.
  • LTX-2.5 from Lightricks generates synchronized audio and goes up to 4K, with clips of up to 20 seconds on its fast variant. Its community license is free for companies under $10 million in annual revenue.

Text to Finished Marketing Videos

Everything above hands you clips. Most marketers and YouTubers need a finished video: a script, scenes, a voiceover, captions and music in the right order. That is a different job, and it is the one InVideo AI is built for.

InVideo AI

InVideo AI turns a prompt into a complete edited video. It handles the whole chain:

  • It writes the script and splits it into scenes.
  • It pulls stock footage or generates new clips for each scene.
  • It adds an AI voiceover, captions and music.
  • It gives you a timeline to fix whatever it got wrong.

InVideo AI Pro

  • 1,000 credits a month per seat
  • Seedance 2.5 at about 56 credits per 5 seconds of 720p
  • Script, voiceover, captions and stock footage in one draft
  • Exports and manual timeline edits don't use credits
  • $15 a month when billed annually

The generative clips come from the same models in this article, with Veo 3.1, Kling, Hailuo, Wan and Seedance among them. So you are paying for the assembly as much as for the footage.

Credits only pay for generation in InVideo AI. Editing on the timeline and exporting are free, so a video made mostly from stock footage and voiceover costs very little, while one built from Seedance clips spends about 11 credits a second. Unused credits don’t roll over, and the $9 Basic plan with 190 credits can’t use Seedance 2.5, so Pro is the realistic plan if you want generated footage in your videos.

If you are deciding between a synthetic voice and recording your own, my comparison of voiceover and AI text to speech covers where each one holds up.

Why it fits:

  • A publishable draft from one prompt, with script and voiceover included.
  • Several premium video models inside one subscription.
  • Free exports and free manual edits.

Watch out for:

  • Generated clips still cost credits at each model’s rate.
  • Credits expire at the end of the month.
  • The free plan’s credits are limited and reset every Monday.

AI Presenters and Video Editors

These tools sit next to text to video generation rather than inside it. You pick them when you need a person on screen or when the footage already exists.

JobToolWhy It FitsCatch

A short clip inside a designCanvaCreate a video clip makes 8-second clips with sound, powered by Veo 3Pro gets up to 20 uses a month shared with other AI tools; the free plan gets none

Synthesia changed its plans on October 1, 2026: Creator was renamed Pro at the same price, and the new credit allowances now apply to every plan. HeyGen’s credit plans work the same way, and its old unlimited avatar plans exist only for legacy subscribers, so check the current HeyGen plans rather than an old review.

For editing recorded footage, VEED is the easiest browser editor to hand to someone new, and my list of video editing software covers desktop editors if you need more control. For shorts, Submagic styles captions on talking-head clips and OpusClip cuts long recordings into clips. The short-form video workflow for small businesses shows how those pieces fit into a weekly routine. If you already design in Canva, its video clip tool covers a quick 8-second shot without another subscription.

What Video Credits Buy

Credits pay for every generation, including the ones you reject. That is the cost most plan pages leave you to work out yourself.

Take Runway’s Standard plan as an example. It gives 625 credits a month and Gen-4.5 costs 12 credits a second, so a 10-second clip uses 120 credits. Say you keep 1 clip out of every 3 you generate: that usable 10-second shot has cost 360 credits, and the month’s allowance gives you about 17 seconds you can actually use.

Bar chart of seconds of generated video per month on entry paid plans: Google AI Pro up to 400 s with Veo 3.1 Fast or 80 s with Veo 3.1 Quality, InVideo AI Pro about 89 s, Hailuo Standard about 84 s, Kling Standard 55 s and Runway Standard 52 s

Three things move the number more than the plan price does:

  • The model tier. Google AI Pro’s 1,000 credits buy 80 seconds of Veo 3.1 Quality or up to 400 seconds of Veo 3.1 Fast.
  • Sound and resolution. Kling 3.0 charges 12 credits a second at 1080p with sound and 6 at 720p without it.
  • Your keep rate. Drafting in a cheap model and finishing in an expensive one wastes far fewer credits than retrying the expensive one.

A subscription and an API are also separate bills. The Gemini API charges $0.40 a second for Veo 3.1 at 720p or 1080p, so an 8-second clip costs $3.20 there whatever Google AI plan you hold, while Veo 3.1 Fast costs $0.10 a second at 720p.

Free AI Video Generators

Free plans in this category come in three shapes: a daily allowance that resets, a weekly one and a one-time grant that never comes back. A daily allowance is the only kind that lets you keep testing for free.

  • Google Flow: 50 credits a day for everyone, which covers 2 Veo 3.1 Fast clips or 3 10-second Omni Flash clips at 720p. Unused daily credits don’t roll over.
  • Runway: 125 one-time credits, about 10 seconds of Gen-4.5.
  • Hailuo: one-time trial credits on the free plan.
  • InVideo AI: a limited credit allowance that resets every Monday at midnight UTC.
  • Synthesia: 10 minutes of presenter video and 500 credits a month, with a watermark.
  • HeyGen: 3 videos a month of up to 1 minute each, with a watermark.

For free text to video AI that you can keep using, Google Flow is the clear starting point. The others are good for one proper trial of your real brief, so save their one-time credits for that test instead of spending them on random prompts.

Choosing a Tool for Client Work

Client work adds a few checks that a personal project can skip:

  • Watermarks and plan rights. Free plans on Synthesia, HeyGen, VEED and OpusClip watermark their exports. Read the commercial-use terms of the exact plan you will bill the client from.
  • Likeness and voices. A custom avatar or cloned voice of a real person needs that person’s written consent, and an actor in a reference image needs the same.
  • Region. Seedance 2.5 in Dreamina rolled out region by region, so confirm the model works in your client’s country and account before you promise it.
  • Model churn. OpenAI shut down the Sora app on April 26, 2026 and the Sora API on September 24, 2026. A workflow tied to one model should have a second model ready.
  • Repeatability. Save prompts, seeds where the tool exposes them and every reference file, because a client will ask for the same character next month.

If the client’s real need is a steady stream of short posts from existing content, a model is the wrong first purchase. The process in turning one blog post into 12 short videos gets there with a script first and generation second.

FAQs on AI Text to Video Generators

What is the best AI text to video generator?

For most people, Google Veo 3.1 in Flow on the Google AI Pro plan is the best starting point. It makes polished clips with native sound, every user gets 50 free Flow credits a day to test it and the same credits cover the faster Gemini Omni Flash model. Runway is better for directed shots, Seedance 2.5 for single takes up to 30 seconds and InVideo AI for finished videos with a script and voiceover.

Is there a free AI text to video generator?

Google Flow gives everyone 50 credits a day, which covers 2 Veo 3.1 Fast clips or 3 10-second Gemini Omni Flash clips at 720p. Runway gives 125 one-time credits, InVideo AI resets a small free allowance every Monday and Synthesia’s free plan includes 10 minutes of presenter video a month with a watermark.

Is OpenAI Sora still available?

No. OpenAI discontinued the Sora app and website on April 26, 2026 and the Sora API on September 24, 2026. Existing users can export their videos from sora.chatgpt.com/sunset, and OpenAI says it will email users if it sets a final export window.

Does a video subscription include API credits?

Usually not. Google AI Pro’s Flow credits don’t cover the Gemini API, which bills Veo 3.1 at $0.40 a second for 720p or 1080p. Treat the app subscription and the developer API as separate purchases unless the plan page says otherwise.

Do unused video credits carry over?

It depends on the plan. Google’s 50 daily Flow credits don’t roll over, and neither do InVideo AI or VEED credits. Runway’s Max plan carries credits over for 1 month, HeyGen’s monthly plans keep them for 1 extra month and OpusClip Pro keeps them for 2 months.

Does unlimited mean unlimited generation?

Rarely. Runway’s current plans are all credit-based, and HeyGen’s unlimited avatar plans exist only for legacy subscribers. When a plan says unlimited, check which models and which speed tier the word covers.

Final Remarks

Write one real brief, the kind of clip you would actually publish, and run it through Google Flow’s free daily credits first. If Veo 3.1 or Omni Flash gets you there, Google AI Pro is the plan to buy; if the shot needs directing, longer takes or a finished edit, move to Runway, Seedance 2.5 or InVideo AI with that same brief and compare the seconds of usable video each one gives you.
