These are different tools. For cinematic or social clips generated from a prompt, use a generative model such as Google Veo or Runway. For a person talking to camera, such as training videos, product demos or sales outreach, use an avatar tool such as HeyGen, which turns a script into a presenter video.
How long do your videos need to be?
Generative models produce short clips, typically about eight seconds for Veo, which you extend or stitch together. Avatar tools handle much longer videos: HeyGen's paid plans allow up to 30 or 60 minutes per video. If you need long, scripted content, an avatar tool will be far quicker.
Do you need sound in the generated video?
Veo 3 generates sound effects, ambient noise and dialogue natively, which saves a separate audio step. With other generators you may need to add music and voiceover afterwards, either in the same platform or in an editor.
How is pricing measured?
Most tools sell credits rather than videos, so compare what a credit buys. Runway's Standard plan includes 625 credits a month, HeyGen's Creator plan 600 credits, and Google AI Pro 1,000 Flow credits. Vendors rarely say how many finished videos those credits produce, so start with a free tier or the cheapest plan and measure your own usage.
Prices in US dollars, checked November 14, 2026 on each vendor's official pricing page. Plans change often, so confirm before you buy.
How we pick and rank these tools
We don't run hands-on lab tests of every tool. Instead, each pick is the result of structured research, refreshed every month, and scored against the criteria that matter most for this category.

Commercial-use terms
Official sources first. Features, limits and plans come from each vendor's own site, documentation and pricing page, which we re-read before every update.
Prices checked on the day. Every price shows the date it was verified. Promotions are labelled as such, and month-to-month and yearly billing are kept separate.
Real-world signal. We weigh public changelogs, documented limits and independent user reviews (G2, Trustpilot, Reddit, developer forums) for reliability and support issues.
Fit over hype. Picks are ranked by how well a tool fits a specific need, not by brand size, and every pick lists a genuine drawback.
Independent. Rankings are never paid for. Sponsored placements are always labelled and are kept out of these picks.
Refreshed monthly. We re-check picks, prices and plans every month and whenever a vendor ships a major change.
Google Veo leads for realistic clips with native sound, Runway is the best all-in-one creative studio, and HeyGen is the best for avatar and presenter videos.
Is there a free AI video generator?
Runway gives 125 one-time free credits and HeyGen's free plan makes three watermarked videos a month. Google lists video generation from its paid AI Plus plan ($4.99/month in the US).
Can AI video generators make videos with sound?
Yes. Google Veo 3 generates sound effects, ambient noise and dialogue natively. Many other tools require you to add audio separately.
How long can AI-generated videos be?
Generative models usually make clips of about eight seconds that you can extend. Avatar tools such as HeyGen create videos up to 30 to 60 minutes on paid plans.
