Why Your AI Video Generator Choice Matters
"AI video generator" covers three very different kinds of software, and most buying mistakes come from mixing them up.
- Avatar video tools turn a script into a video of a digital presenter talking to camera. HeyGen and Synthesia lead here. This is the format for training modules, onboarding, internal announcements, product walkthroughs and localized versions of the same message.
- Generative video tools create footage from a text prompt or an image: a product shot, a scene, a short clip that never existed. Runway is the best-known option, and InVideo now gives access to several generative models in one editor. This is the format for ads, social clips and creative B-roll.
- Text-to-video editors assemble a video from your script, blog post, slides or recording, using stock footage, AI voices and captions. Pictory works this way, and Descript does the same for recorded video by letting you edit the transcript.
A training team that buys a generative model will struggle to produce a consistent 10-minute compliance module. A social team that buys an avatar platform will find it does not produce the kind of eye-catching footage that stops a scroll. Start with the format, then compare plans.
The other thing that catches buyers out is how usage is metered. Almost every tool here now sells credits rather than unlimited videos, and credits are spent at different rates depending on the model, the length and the resolution. Free plans add watermarks, and several cap video length at one to five minutes. We cover what each plan actually includes, so you can estimate what a month of real work costs.
How we chose
We compared six tools that business teams shortlist most often for video work: HeyGen, Synthesia, Descript, Runway, Pictory and InVideo. For each, we checked the vendor's own pricing page and help center in October 2026 and compared:
- What kind of video it makes (avatar, generative or text-to-video editing)
- What the free plan allows, and whether exports are watermarked
- How credits or minutes are counted and whether they roll over
- Team features: seats, brand kits, SSO, SCORM export for learning platforms
- Monthly versus annual pricing
We did not run hands-on tests for this guide. It compares published plans, features and trade-offs.

HeyGen Review
HeyGen started as an avatar video tool and has grown into a broad AI video platform. You write or paste a script, pick a stock avatar or create one of yourself, and HeyGen generates a presenter video. On top of that it offers video translation with lip sync, an AI video generator, photo avatars and voice cloning, all paid for from one pool of credits.
Key features
- 500+ stock video avatars on the free plan and 700+ on paid plans, plus custom video avatars and unlimited photo avatars on paid plans
- Avatar IV generation, with extended use on paid plans
- Video translation into 175+ languages and dialects on paid plans (30+ on Free)
- Voice cloning, PowerPoint and PDF import, video templates and a screen recorder
- Business plan: SAML/SSO, workspace collaboration, interactive video with quizzes, SCORM export, LMS integrations and integrations with HubSpot, Zapier, Make and n8n
Pricing
- Free: 3 videos per month, up to 1 minute each, 500+ stock avatars, 1 custom video avatar, 30+ languages. Watermark removal is a paid feature
- Creator: $29/month, or $24/month billed yearly ($288/year). 600 credits a month, videos up to 30 minutes, 1080p export, watermark removal, voice cloning
- Pro: $49/month, or $41/month billed yearly. 1,000 credits a month, 4K export, access to all advanced AI models. Higher Pro tiers add credits, up to 100,000 credits a month at $4,300
- Business: $149/month, or $119/month billed yearly ($1,428/year), plus $20 per added seat per month. 1,500 credits a month, videos up to 60 minutes, 4K, 5 custom video avatars, SSO and SCORM
- Enterprise: custom pricing, no video duration limit, SCIM, multi-workspace control and a dedicated success manager
HeyGen's credits are its single currency for every feature, and the number a video uses depends on the model, the duration and the complexity. Unused monthly credits roll over for one more month; on annual plans they accumulate until renewal.
Who it's for
Marketing, sales enablement, customer education and HR teams that want presenter videos, localized versions of the same video and some generative footage without buying three tools.
Where it falls short
- Credit costs vary by feature, so it is hard to predict exactly how many videos a plan covers before you try it
- The free plan's 1-minute limit and watermark make it a test drive, not a production option
- Team features such as SSO and SCORM start at the Business plan, not on Creator or Pro
- Avatar video still suits structured, talking-head content better than storytelling or emotional brand work
Synthesia Review
Synthesia is the avatar video platform most associated with corporate training. You build a video from a script and templates, choose an AI avatar and a voice in one of 140+ languages, and publish it as a share link or a download. Its product decisions lean toward learning and development teams: interactive videos, quizzes, SCORM export on Enterprise, and AI roleplay training that you add per learner.
Key features
- 125+ stock avatars on Starter, 180+ on Pro and 240+ on Enterprise, with personal avatars on Pro (5) and Enterprise (unlimited)
- 140+ languages and voices, with 1-click translation into 140+ languages on Enterprise
- AI Video Assistant, templates, PowerPoint import, auto-generated captions and a media library with stock from Getty Images and Pexels on paid plans
- Interactive videos and branded video pages on Pro
- Enterprise: SCORM export, SAML/SSO, brand kits, live team collaboration and unlimited video minutes
Pricing
- Basic (free): 10 minutes of video a month, 9 AI avatars, 1 editor. You can share by link, but videos carry a Synthesia watermark and downloading needs a paid plan
- Starter: $29/month billed monthly, or $18/month billed yearly. About 12 minutes of video a month, or about 150 minutes a year on annual billing, on top of the free allowance. Downloads, logo removal, 1 editor and 3 guests
- Pro: $89/month billed monthly, or $64/month billed yearly. About 60 minutes a month, or about 720 minutes a year, on top of the free allowance. 5 personal avatars, interactive videos, 1 editor and 5 guests. Pro has higher credit tiers for more minutes
- Enterprise: custom pricing with unlimited video minutes and a custom number of editors
- Roleplay learner seats: an add-on priced per learner per month
Synthesia now meters usage in credits: its pricing page counts 100 credits per minute of video, with dubbing and surveys drawing from the same pool.
Who it's for
L&D, HR, compliance and customer training teams producing many structured videos, especially at larger companies that need SCORM, SSO and review workflows.
Where it falls short
- The free plan cannot download videos, so it is only useful for evaluation
- Starter and Pro include one editor each; multi-editor teams are pushed toward Enterprise
- SCORM export, SSO and 1-click translation sit on the custom-priced Enterprise plan
- Minutes per month on Starter are small, so regular producers will need Pro or Enterprise
Descript Review
Descript is not a pure AI generator. It is a video and podcast editor where you edit the video by editing its transcript: delete a sentence in the text and it disappears from the video. Its AI features, grouped under an AI co-editor called Underlord, cover filler word removal, Studio Sound, eye contact correction, AI voices, and on higher plans AI avatars and generative video.
Key features
- Text-based video editing with automatic transcription
- Underlord AI co-editor, Studio Sound and filler word removal on paid plans
- AI speech with custom voice clones and eye contact correction
- Generative video with current AI models and AI avatars on Creator and Business
- Business: translation and dubbing into 30+ languages, custom avatars from a photo or text, and team-wide brand tools
Pricing
Prices are per person:
- Free: 1 media hour a month, 100 one-time AI credits, 720p export with a watermark
- Hobbyist: $16/month billed yearly, or $24 monthly. 10 media hours and 400 AI credits a month, 1080p without a watermark
- Creator: $24/month billed yearly, or $35 monthly. 30 media hours and 800 AI credits a month, 4K export, AI video generation and avatars
- Business: $50/month billed yearly, or $65 monthly. 40 media hours and 1,500 AI credits a month, translation and dubbing, custom avatars
- Enterprise: custom pricing
Who it's for
Teams that still record real people, such as webinars, customer stories, founder updates, podcasts and product demos, and want to cut and polish them fast. It also fits marketers who repurpose long recordings into short clips.
Where it falls short
- It starts from footage you record; it is not the fastest way to make a video from a script alone
- AI video generation and avatars need Creator or Business, not Hobbyist
- Translation and dubbing are a Business feature
- Per-person pricing adds up for larger teams
Runway Review
Runway is a generative AI creative platform. You describe a shot in text or start from an image, and its models generate video clips. It is the tool in this list for producing new footage: product hero shots, ad concepts, background scenes and stylized social clips. Its pricing page lists its own Gen-4.5 model alongside third-party models such as Kling and Seedance.
Key features
- Text-to-video and image-to-video with Gen-4.5, Gen-4 Turbo and other models
- Image, music, voice and sound effect generation on paid plans
- An agentic creative collaborator that can pick the right model for a task
- 4K upscaling (unlimited on Pro and Max), with HDR and ProRes output on Max
- Brand kits and custom voice clones on Pro and Max
Pricing
- Free: 125 one-time credits that do not expire or refresh, access to a limited set of tools, 5 GB storage
- Standard: $15/month, or $12/month billed yearly. 625 credits a month, which Runway says equals 52 seconds of Gen-4.5 or 104 seconds of Gen-4 Turbo. Access to all models, no watermarks, 4K upscaling, 20 GB storage
- Pro: $35/month, or $28/month billed yearly. 2,250 credits a month (187 seconds of Gen-4.5), 1 brand kit, 1 voice clone, unlimited 4K upscaling, 100 GB storage
- Max: $95/month, or $76/month billed yearly. 9,500 credits a month (791 seconds of Gen-4.5), credits roll over for one month, up to 3 brand kits, HDR and ProRes, 500 GB storage
- Team and Enterprise: listed separately on Runway's pricing page
Credits on Standard and Pro reset each billing cycle and do not roll over. Gen-4.5 uses 12 credits per second of video. Extra credits can be bought with a minimum purchase of 1,000.
On rights, Runway's help center says the content you create is yours to use without non-commercial restrictions from Runway, including ads and monetized uploads.
Who it's for
Creative, brand and performance marketing teams that need original footage for ads and social, and agencies producing concepts or B-roll.
Where it falls short
- Seconds, not minutes: 625 credits buys under a minute of Gen-4.5 footage, so plan on Pro or Max for regular work
- No presenter avatars or training features; it produces clips you assemble elsewhere
- Generated clips can take several attempts to get right, and every attempt spends credits
- Individual plans are single-user; teams need the separate Team plan
Pictory Review
Pictory turns text into video. You paste a script or a blog URL, or upload a PowerPoint, and it builds scenes with stock footage, an AI voiceover and captions. It also edits recorded video by transcript, which makes it useful for clipping webinars. Usage is counted in video minutes per year, which is easier to budget than most credit systems.
Key features
- Script to video, URL to video and PowerPoint to video
- Stock video from Getty Images and Storyblocks, plus thousands of music tracks
- AI voices from ElevenLabs in 29 languages, voice cloning on Professional and up
- Automatic captions, highlights and text-based editing of recordings
- Brand kits on every plan; Enterprise adds interactive video hosting, quizzes, SCORM export and SSO
Pricing
- Free trial: 14 days, 15 video minutes, videos up to 5 minutes, 720p export
- Starter: $25/month billed yearly, or $29 monthly. 1 user, 2,400 video minutes a year, 1 brand kit, 1,200 AI credits a year, 1080p, no watermark
- Professional: $35/month billed yearly, or $59 monthly. 1 user, 7,200 video minutes a year, 5 brand kits, custom avatars and voice cloning, 12,000 AI credits a year
- Team: $119/month billed yearly, or $199 monthly. 3+ users, 21,600 video minutes a year, 10 brand kits, a shared team workspace
- Enterprise: custom pricing for 10+ users
Script-to-video projects are capped at 30 minutes per video on paid plans. AI credits are separate from video minutes and pay for generative images, video and avatars; Pictory says Starter's 1,200 yearly credits cover up to 12.5 minutes of generated video or 40 minutes of avatar video.
Who it's for
Content marketers, small businesses and training teams that already have words, such as articles, scripts or slide decks, and want them turned into videos with minimal editing.
Where it falls short
- Output relies on stock footage, so videos can look generic without custom assets
- Paid exports top out at 1080p
- Generative AI credits on Starter are small
- SCORM export, SSO and interactive hosting are Enterprise-only
InVideo Review
InVideo (sold as invideo AI) has moved from a template video editor to a prompt-driven AI video studio. You describe the video you want, and its agents write a script, pull or generate footage, add a voiceover and assemble an edit you can change in a timeline editor. It also gives access to many image and video models from other companies, priced in credits.
Key features
- Prompt-to-video agents (Lite on Starter; Lite, Pro and Ultra on Plus and Max)
- Access to generative video and image models, including Seedance models, with model access depending on plan
- Timeline editor with multiplayer editing and color, audio and 3D tools
- Premium stock footage allowances on every paid plan
- Team seats on every plan, with free guest seats on Plus and Max
Pricing
- Free: limited credits that reset weekly, no card needed. Downloads carry an InVideo watermark, though InVideo says you can share free-plan videos on social media
- Starter: $10 per seat/month billed yearly, or $20 monthly. 400 credits per seat a month, up to 5 seats, Lite agent only, 200 GB storage
- Plus: $30 per seat/month billed yearly, or $60 monthly. 2,000 credits per seat a month, up to 10 seats plus 10 guest seats, all agents and models, 600 GB storage
- Max: $75 per seat/month billed yearly, or $150 monthly. 5,000 credits per seat a month, up to 20 seats plus 20 guest seats, the lowest cost per credit, 2,000 GB storage
InVideo shows its annual prices as 50% off monthly. Unused credits do not roll over, and InVideo says it can change credit costs at any time.
Who it's for
Social media, performance marketing and small business teams that publish a lot of short videos and want an agent to produce the first draft.
Where it falls short
- Credits expire monthly, so unused capacity is lost
- Starter does not include the stronger agents or Seedance 2.5
- Credit costs can change without notice, which makes budgets less predictable
- Not designed for avatar-led training or LMS delivery
Head-to-Head Comparison
Avatar video vs generative video vs text-to-video
- Presenter on screen, same message in many languages: HeyGen or Synthesia.
- New footage that did not exist before: Runway, or InVideo if you want an agent to assemble the edit around it.
- Video built from words you already have: Pictory for scripts, blogs and slides; InVideo for prompt-driven social video.
- Video built from recordings you already have: Descript.
Credits, minutes and limits
- Synthesia counts roughly 100 credits per minute of video and lists minutes on each plan, which makes avatar output fairly easy to forecast.
- Pictory sells video minutes per year (2,400 on Starter), with a separate, smaller pool of AI credits for generative content.
- HeyGen uses one credit pool for everything, and cost per video depends on the model and length.
- Runway credits buy seconds of generated footage: Standard covers 52 seconds of Gen-4.5 a month.
- InVideo credits vary by model, reset monthly and do not roll over.
- Descript meters media hours for editing plus AI credits for AI features.
Free plans and watermarks
- HeyGen: 3 videos a month, up to 1 minute; watermark removal starts on Creator.
- Synthesia: 10 minutes a month with a watermark, and no downloads.
- Descript: 1 media hour a month, 720p, watermarked.
- Runway: 125 one-time credits; Runway lists "no watermarks" as a paid-plan feature.
- Pictory: a 14-day trial rather than a free plan, with 15 video minutes at 720p.
- InVideo: weekly credits, watermarked downloads.
Commercial use
Runway's help center states that you can use what you create commercially without non-commercial restrictions from Runway. InVideo's help center confirms that free-plan videos can be shared on social media, watermark included. For HeyGen, Synthesia, Descript and Pictory, a paid plan removes the watermark, which is the practical requirement for business use. For anything going into paid advertising, read the vendor's terms on stock footage, music and likeness rights for avatars, especially custom avatars of real employees.
How to Choose
-
What will most of your videos be?
- Training, onboarding and internal comms with a presenter: Synthesia (enterprise L&D) or HeyGen (broader use, self-serve team plan).
- Localizing existing videos into other languages: HeyGen.
- Ads, product visuals and social clips that need fresh footage: Runway.
- Turning blogs, scripts and slide decks into videos: Pictory.
- A high volume of short social videos from prompts: InVideo.
- Webinars, interviews and recorded demos: Descript.
-
Do you need an LMS? If videos go into a learning platform, look for SCORM export. HeyGen includes it on its self-serve Business plan. Synthesia and Pictory reserve it for Enterprise.
-
How many people will create? Synthesia's self-serve plans have one editor. Runway's individual plans are single-user. HeyGen Business, Pictory Team and InVideo are built for multiple seats. Descript is priced per person.
-
Estimate a month of real output. Take the number and length of videos you make in a typical month and compare it with each plan's minutes or credits. Generative video burns credits fastest, and failed attempts count.
-
Pay monthly first. Credit systems are hard to judge from a pricing page. One paid month on a monthly plan tells you more than any calculator, then switch to annual billing to save.
Red flags
- Planning production on a free plan: every tool here watermarks, shortens or blocks downloads
- Expecting a generative video model to deliver a consistent 10-minute training module
- Buying annual plans with credits that do not roll over before you know your usage
- Creating a custom avatar of an employee without a written agreement on how it will be used
Pricing Comparison
Lowest paid plan without a watermark, per month:
| Tool | Billed monthly | Billed yearly | What you get |
|---|---|---|---|
| HeyGen Creator | $29 | $24 | 600 credits, videos up to 30 minutes, 1080p |
| Synthesia Starter | $29 | $18 | About 12 minutes a month on top of 10 free, 1 editor |
| Descript Hobbyist | $24 | $16 | 10 media hours, 400 AI credits, 1080p |
| Runway Standard | $15 | $12 | 625 credits (52 seconds of Gen-4.5) |
| Pictory Starter | $29 | $25 | 2,400 video minutes a year, 1080p |
| InVideo Starter | $20 per seat | $10 per seat | 400 credits per seat |
Cost for a team of five
Annual billing, list prices, per year:
- HeyGen Business: $1,428 a year plus $20 per added seat per month, so roughly $2,388 if the base price covers one seat (confirm seat terms with HeyGen).
- Synthesia: self-serve plans have one editor, so five editors means Enterprise at custom pricing.
- Descript Business: $50 x 5 x 12 = $3,000.
- Runway Standard: $12 x 5 x 12 = $720 for five individual plans (the Team plan is priced separately).
- Pictory Team: $119 x 12 = $1,428 for 3+ users; check pricing for five.
- InVideo Plus: $30 x 5 x 12 = $1,800.
Final Recommendations
1) HeyGen: best overall for business video
HeyGen covers the widest range of business video in one product: presenter videos, translation into 175+ languages, and generative models on Pro. Its Business plan gives teams SSO, SCORM and interactive video without a sales call. Start with Creator to learn the credit system, then move to Business when more than one person creates.
2) Synthesia: best for enterprise training
For companies where video is mainly training and internal communication, Synthesia is built for that job, with interactive videos on Pro and SCORM, SSO and unlimited minutes on Enterprise. Expect to talk to sales if more than one person edits.
3) Descript: best for editing recorded video
If real people are still on camera, Descript makes editing as fast as editing a document and adds AI voices, avatars and dubbing on higher plans.
4) Runway: best for generative footage
For ads and social content that need new visuals, Runway's models and 4K upscaling are a strong choice, with clear commercial rights. Budget for Pro or Max if you generate regularly.
5) Pictory: best for scripts, blogs and slides
Pictory is the most predictable way to turn existing written content into videos, with thousands of video minutes a year on every paid plan.
6) InVideo: best for high-volume social video
InVideo gives social and marketing teams prompt-to-video agents and many generative models at a low per-seat price. Watch credit use closely, because unused credits expire each month.
Conclusion
There is no single best AI video generator, only the best one for the kind of video you make. List the five videos your team made most recently, sort them into avatar, generative or text-to-video, and trial the one or two tools that match. Use a monthly plan for the first month, measure how many credits or minutes you really use, and only then commit to annual billing.
