At a glance

1. Runway: best AI video generator overall

Runway is a creative AI studio for generating and editing video and images, and the strongest all-round pick because one subscription gives you several different models. Its pricing page (runwayml.com now redirects to runway.com) says paid plans include "all AI video and image models", and lists third-party models such as Kling 4.0 and Seedance 2.0 Pro alongside Runway's own, so you are not locked into one look.

The plans are Free (125 one-time credits), Standard at US$15 a month (US$12 billed annually) with 625 credits, Pro at US$35 (US$28 annual) with 2,250 credits, and Max at US$95 (US$76 annual) with 9,500 credits and early access to new models. Standard removes watermarks and adds 4K upscaling; Pro and Max add unlimited Topaz AI upscaling. Standard and Pro credits do not roll over, while Max credits roll over for one month.

The weak point is licensing clarity. The pricing page does not address commercial use, and secondary sources disagree about which plans are cleared for client work, so read Runway's terms before you deliver paid projects. Credit cost per clip also varies by model, so the headline credit number is only a guide.

Pros

• Many video and image models under one subscription
• Watermark-free output and 4K upscaling from Standard
• Clear ladder from US$15 to US$95 with annual discounts of around 20%
• Max credits roll over for a month

Cons

• 625 credits on Standard is modest for iterating on video
• Commercial-use terms are not stated on the pricing page
• Credits on Standard and Pro expire monthly
• Free plan is a one-time 125 credits, not a recurring allowance

Pricing: Standard US$15/month (US$12 billed yearly), Pro US$35 (US$28), Max US$95 (US$76), as of 29 October 2026, shown in US dollars.

Best for: Creators, marketers and filmmakers who want to try several video models without juggling subscriptions.

2. Luma Dream Machine: best for polished cinematic clips

Luma is the company behind the Dream Machine video generator, and its homepage now leads with Luma Agents and the Ray 3.2 video model rather than the Dream Machine name. One third-party review says the older Dream Machine plan ladder still exists as a legacy option (eesel), so check which one you are buying.

On the current pricing page, Plus is US$30 a month (US$25 billed yearly, US$300 a year) with 10,000 credits, Pro is US$90 (US$75 yearly) with 40,000, and Ultra is US$300 (US$250 yearly) with 150,000. Team and Enterprise are contact-sales. Commercial use is listed as included on Plus and inherited by higher plans. The page does not give per-clip credit costs in a way we could compare with Runway.

Luma has no cheap tier, which is the main reason it sits behind Runway. If you only make occasional clips, a US$30 minimum is steep. For agencies that value consistent image-to-video quality and clear commercial rights, it is the better choice.

Pros

• Commercial use listed as included from the entry paid plan
• Ray 3.2 is the newest video model on the homepage
• Clear ladder up to 150,000 credits for heavy use
• Plus includes Luma and third-party image and video models

Cons

• US$30 is the highest entry price on this list
• Product naming has shifted from Dream Machine to Agents and Ray
• Resolution and watermark rules per plan are not stated on the page
• Credit allowances are hard to translate into seconds of video

Pricing: Plus US$30/month (US$25 billed yearly), Pro US$90 (US$75), Ultra US$300 (US$250), as of 29 October 2026.

Best for: Agencies and freelancers who deliver client work and want commercial rights stated from day one.

3. Pika: best budget AI video generator

Pika is an AI video and image platform that bundles its own model (Pika 2.5) with third-party models, and it has the cheapest paid plan here that comes with a commercial licence. Its pricing page shows Free (no monthly credits, packs only, no commercial licence), Starter at US$10 a month (US$8 annual) with 900 credits, Creator at US$35 (US$28) with 3,150 credits, and Fancy from US$95 up to US$880 a month depending on credits.

The homepage lists Video Studio, Extend Video, Pika Soundtrack for music and effects, and image tools such as Character Studio and Product Shot. It claims multi-shot clips of up to 30 seconds. Third-party models named on the homepage include Seedance 2.5, MiniMax H3 and Wan 3.0.

The compromise is that 900 credits is a thin monthly allowance for video, and the Free plan gives nothing recurring. Parallel generation limits also rise with price: Starter allows 2 video jobs at once, Creator 8, and Fancy is unlimited.

Pros

• Lowest paid entry price with a commercial licence and no watermark
• Includes third-party models as well as Pika 2.5
• Handy extras such as soundtrack and extend tools
• Annual billing takes about 20% off

Cons

• 900 credits on Starter will not stretch far
• Only 2 concurrent video jobs on Starter
• Free plan has no monthly credits and no commercial licence
• Fancy pricing is a wide range rather than a fixed tier

Pricing: Starter US$10/month (US$8 annual), Creator US$35 (US$28), Fancy US$95 to US$880, as of 29 October 2026.

Best for: Beginners and social creators who want to experiment cheaply.

4. HeyGen: best for presenter and translated videos

HeyGen is an AI avatar video platform that turns scripts, images, audio or uploaded decks into presenter videos, and it translates existing videos with voice cloning and lip-sync. Its homepage claims lip-sync in 175+ languages and dialects, and lists GDPR, SOC 2 Type II and CCPA among its compliance credentials. Treat the user counts and awards on the page as vendor marketing.

On the pricing page, Free allows 3 watermarked videos a month of up to one minute. Creator is US$29 a month (US$24 billed annually) with 600 credits, videos up to 30 minutes, 175+ translation languages and up to 1080p export. Pro is US$49 a month for 1,000 credits and up to 4K, scaling to 100,000 credits at US$4,300. Business is US$149 plus US$20 per extra seat.

This is a different job from Runway or Luma: you are making talking presenters, not cinematic shots. The pricing page does not state commercial-use rights for individual plans; only Enterprise mentions custom commercial terms, so ask support if you are producing paid client work.

Pros

• Strong translation and lip-sync for localisation
• Watermark removed from Creator, with up to 1080p and 30-minute videos
• Publishes security credentials (SOC 2 Type II, GDPR)
• Custom avatar from your own likeness, with identity verification

Cons

• Not a text-to-cinematic-clip tool
• Commercial terms not set out on the pricing page
• Credit-based tiers scale quickly (Pro up to US$4,300 a month)
• Free plan is tiny and watermarked

Pricing: Creator US$29/month (US$24 billed yearly), Pro from US$49/month, Business US$149 plus US$20 per seat, as of 29 October 2026.

Best for: Marketers, sales teams and course creators making explainer, product and localised videos.

5. Synthesia: best for enterprise training and compliance

Synthesia is an AI avatar video platform for business, used for training, onboarding and internal communications. Its homepage lists SOC 2 Type II, ISO 27001, ISO 27701 and ISO 42001 certifications and GDPR compliance with EU data residency, which gives it the strongest security story here for UK and EU buyers. User and customer figures on the page are vendor claims.

The pricing page shows a free Basic plan (10 minutes of video a month, watermarked, 9 stock avatars), Starter at US$19 a month (US$9 first month; US$14 a month billed annually) with 1,250 credits and 125+ stock avatars, and Pro at US$89 (US$49 first month; US$59 annually) with 6,000 credits, 180+ avatars and branded video pages. Enterprise adds unlimited minutes, SSO, SCIM and SCORM export. The calculator uses roughly 100 credits per minute of video.

The pricing page does not name a currency or set out commercial-use terms. Minutes are capped on every self-serve plan, and the features that matter to larger teams, such as SSO, sit in Enterprise.

Pros

• Published security certifications and EU data residency
• SCORM export and SSO on Enterprise suit learning teams
• 140+ languages and voices
• Free plan lets you test avatars before paying

Cons

• Roughly 12 minutes a month on Starter and about 60 on Pro
• Promotional first-month pricing makes real cost harder to read
• Commercial terms not on the pricing page
• Enterprise features need a sales conversation

Pricing: Starter US$19/month (US$14 billed annually), Pro US$89 (US$59 annually), as of 29 October 2026. First-month prices are promotional.

Best for: Larger companies and learning teams that need audited security and structured training video.

How we compared these tools

We compared these tools by reading each vendor's own pricing and product pages on 29 October 2026, then checking third-party coverage where a page was unclear. We did not generate test clips or run quality benchmarks, so we make no claims about realism or motion quality. Where a plan detail comes from outside the vendor, we say so.

Weighting: price transparency and entry cost (25%), licensing clarity (25%), allowance versus real output (20%), breadth of use cases (15%) and lock-in or security (15%). Video credits are the hard part: vendors rarely state seconds of video per plan, so treat all allowances as rough guides and test on a free tier first.

How to choose

• If you want the widest choice of models in one plan, pick Runway.
• If you deliver client work and want commercial rights stated up front, pick Luma.
• If you are experimenting on a budget, pick Pika Starter.
• If you need presenters, explainers or translated videos, pick HeyGen.
• If you work in a large or regulated company, pick Synthesia.
• If you also need still images first, see our guide to the best AI image generators; for narration, see the best AI voice generators.

Frequently asked questions

What is the best AI video generator in 2026?

Runway is the best AI video generator for most creators in 2026 because its paid plans start at US$15 a month and include a range of video and image models. For talking presenters, HeyGen is better. For enterprise training with audited security, Synthesia is the safer choice.

Which AI video generator is cheapest?

Pika Starter at US$10 a month (US$8 billed annually) is the cheapest paid plan here, and it lists a commercial licence. Runway Standard is US$15 a month, Synthesia Starter is US$19 and HeyGen Creator is US$29. Luma starts at US$30 a month, so it is the most expensive entry point.

Can I use AI-generated video commercially?

It depends on the plan and the vendor. Luma lists commercial use as included on its paid plans and Pika lists a commercial licence from Starter. Runway, HeyGen and Synthesia do not state commercial rights on their pricing pages, so check their terms before you deliver client work.

What is the difference between Runway and HeyGen?

Runway generates and edits cinematic video clips from prompts and images using multiple models. HeyGen makes presenter videos with AI avatars and translates existing footage with lip-sync. They solve different jobs, and many teams use one of each: Runway for visuals and HeyGen for explanatory or localised content.

Do AI video credits expire?

Often, yes. On Runway, Standard and Pro credits do not roll over, while Max credits roll over for one month. Synthesia credits bought separately last 12 months, according to its pricing page. Most other plans in this list reset credits each billing period, so avoid buying a large annual plan until you know your usage.

Is there a free AI video generator worth trying?

HeyGen and Synthesia both have free plans with watermarks, giving you a taste of avatar video. Runway gives 125 one-time credits, and Pika has a free plan without monthly credits. None of these free options is a substitute for a paid plan if you need regular output.
