AI video generation FAQs
What is an AI video generator?
An AI video generator is software that uses artificial intelligence to create videos automatically, without cameras, filming, or editing skills. You can generate videos from text prompts, scripts, documents, or URLs. Synthesia's AI video generator combines two approaches: avatar-based video for professional presenter-led content, and generative AI video for cinematic clips using models like Veo 3.
Is Synthesia's AI video generator free?
Yes, Synthesia's AI video generator is free to use. The free plan includes up to 10 minutes of video per month, access to AI avatars, voiceovers in 160+ languages, and AI asset generation in the AI Playground with models such as Veo 3. No credit card required to get started.
How is Synthesia different from AI video generators like Sora or Veo 3?
Sora and Veo 3 are generative AI models that create short cinematic clips from text prompts. Synthesia is a complete AI video platform built for professional and business use. You can create presenter-led videos with AI avatars for training, marketing, or communications, and also generate cinematic B-roll using Veo 3 and Sora directly inside Synthesia. The result is polished, brand-consistent video that generative clip tools aren't designed to produce.
How long does it take to generate an AI video?
Most Synthesia videos generate in minutes. AI clips in the Playground typically take around a minute. A full presenter-led video, including scripting, customizing, and generating, usually takes under 10 minutes from start to finish.
Can I make AI-generated videos without any video editing experience?
Yes. Synthesia is designed so anyone can create professional AI-generated videos regardless of technical skill. The editor works like a slide deck. Edit your script, choose an avatar, and generate. No specialist skills required.
What kinds of videos can I make with Synthesia's AI video generator?
Synthesia supports a wide range of video types. Presenter-led videos work well for training, onboarding, sales enablement, internal communications, and marketing. The AI Playground lets you generate short clips for social media, product showcases, or B-roll. You can combine both in a single video — an avatar-led presentation with AI-generated visuals woven in.
Can I generate AI videos in multiple languages?
Yes. Synthesia supports 160+ languages for AI voiceovers and translation. Create a video once and translate it into multiple languages with one click, without re-recording. Auto-generated captions are also available for every language version.
Can I create a custom AI avatar that looks like me?
Yes. Synthesia lets you create a personal AI avatar from a short recording of yourself. Your avatar can then generate videos at any time without filming again. You can also choose from 240+ pre-built AI avatars if you prefer.
Is Synthesia's AI video generator suitable for enterprise use?
Yes. Synthesia is built for enterprise teams and is trusted by over 50,000 businesses including 90% of Fortune 100 companies. The platform is SOC 2 Type II certified, ISO 42001 compliant, and GDPR compliant, with Brand Kit for consistent branding, SSO and permission controls, and live collaboration for teams working at scale.
What file formats can I export AI-generated videos in?
You can export AI-generated videos from Synthesia as MP4 files, share via a public link, or embed them on any website using an embed code. Enterprise plan users can also export as SCORM packages (1.2 and 2004) for direct upload to an LMS.
