What is an AI video generator?
Software that creates professional videos from text, images, or URLs using artificial intelligence — no cameras, actors, or editing software required. Synthesys specifically combines 1,000+ AI avatars, 400+ voices, and 140+ languages with multi-model AI orchestration (multiple AI models working together) to produce ads, UGC content, training videos, product demos, and commercials in minutes. The distinction from basic tools: this isn't slideshow software that adds transitions to images. It's a full production pipeline — scripting, presenter selection, voice generation, lip-sync, rendering — that outputs video indistinguishable from traditional production. One platform replaces agencies, creators, and production crews.
What types of videos can I create?
Every major video format from a single platform. UGC-style social ads (the creator-energy format that converts on TikTok and Instagram). AI avatar presentations (a human presenter delivers your script with natural lip-sync). Product demos and showcase videos (turn product photos into video). Video sales letters (conversion-optimized long-form video). TikTok, Instagram Reels, and YouTube Shorts (vertical, hook-first content). Facebook and YouTube ads (platform-specific formats and pacing). Cinematic commercials (broadcast-ready quality for TV and streaming). Training and e-learning content (up to 30 minutes per video). Multilingual dubbed videos (140+ languages with lip-sync). Each format has dedicated templates, workflows, and AI model selection optimized for that specific output.
How does AI video generation work?
Three steps. First, choose your input: type a script, paste a URL (the AI scrapes the content), drop a product image, or select a template. Second, pick an AI avatar from 1,000+ options, choose a voice from 400+ in 140+ languages, and customize the script, pacing, and style. Third, click generate. The AI handles everything from there — voice synthesis, lip-sync alignment, facial expressions, head movements, transitions, and rendering. Your finished video is ready in minutes, downloadable in HD (1080p) or 4K. If you want to iterate, change the script and regenerate — same avatar, same voice, new video. No editing software at any point in the process.
What AI models does Synthesys use?
Multiple frontier models working together through multi-model orchestration — Sora 2, Google VEO 3.1, Wan 2.5, Kling 3, Seedream, and more. Rather than relying on a single AI engine (which means compromising on some capabilities), the system selects the optimal model for each component: one model for photorealistic avatar rendering, another for cinematic motion generation, a third for voice synthesis, and so on. The AI agent handles this selection automatically. New models are integrated as they launch — when the next breakthrough in video AI ships, it appears in your Synthesys dashboard without switching providers. You always have access to the latest technology without managing multiple subscriptions.
How much does AI video cost compared to traditional production?
Traditional video production runs $5,000-$20,000 per video — that covers talent, equipment, studio rental, crew, post-production, and revisions. And that's per video, before you account for the 2-4 week timeline. Synthesys generates equivalent-quality videos starting from approximately $0.50 per video, depending on length and model complexity. That's a 90-95% cost reduction. In practical terms: a full month of video content (20-30 videos across multiple formats and platforms) costs less than a single traditional shoot day. The savings compound further for multilingual content — translating one video into 10 languages traditionally costs $10,000-$50,000 in dubbing. With AI, it's included.
Do I need video editing experience?
No — and that's by design. Synthesys is built for marketers, business owners, and content creators, not professional video editors. Describe what you want in plain language, select your preferences (avatar, voice, style, format), and the AI handles scripting, avatar selection, voice generation, lip-sync, rendering, and export. Zero editing software, zero technical skills, zero post-production workflow. The interface is point-and-click. If you can write an email, you can produce a professional video. That said, if you want granular control, you can edit the AI-generated script line by line, adjust pacing, choose specific models, and customize every element before generating.
Can I create videos in multiple languages?
Yes. Over 140 languages with 400+ voice options and frame-accurate lip-sync. The AI matches mouth movements to each language's phonemes, so a Spanish version shows Spanish lip shapes rather than English lip-sync with a Spanish voiceover. Create one video concept and deploy it across US, European, Latin American, Asian, and Middle Eastern markets — global campaigns from one production effort. For international brands, this eliminates the most expensive part of global content: producing separate videos per language. One script, one avatar, one production session — 10, 20, or 50 localized versions ready to distribute. The per-language cost is negligible compared to traditional dubbing studios.
Can I use the videos commercially?
Full commercial rights on every Synthesys plan. YouTube monetized content, paid ads on any platform, client deliverables, social media distribution, training materials, product pages, broadcast TV, streaming ad placements, and any other business application. No royalties, no attribution requirements, no usage restrictions, no per-video licensing fees. The license is perpetual — videos you generate today are yours to use and distribute indefinitely. This includes agency use: produce videos for clients and deliver without additional licensing conversations. Important distinction: some AI video tools restrict commercial use to premium plans or charge incremental fees for paid media distribution. Synthesys includes full rights at every tier.
What video formats and resolutions are supported?
Export in HD (1080p) or 4K resolution. Supported aspect ratios cover every major platform: 16:9 landscape for YouTube, websites, and TV broadcast. 9:16 vertical for TikTok, Instagram Reels, YouTube Shorts, and Stories. 1:1 square for Facebook and Instagram feeds. Download as MP4 ready to publish anywhere — no conversion or reformatting needed. The system also optimizes file compression for each platform's specific encoding requirements, so videos stay sharp after upload rather than losing quality to platform re-encoding. For brands producing content across multiple channels, you generate one video and export in every format from the same project.
How is Synthesys different from other AI video generators?
Three fundamental differences. First, multi-model orchestration: most competitors are locked to a single AI model. Synthesys routes each task to the optimal model (Sora 2, VEO 3.1, Kling 3, etc.), producing higher quality than any single model alone. Second, format coverage: most tools specialize in one format. Synthesys creates ads, UGC, avatar videos, commercials, dubbing, voice, and product videos — all from one subscription, one interface. Third, scale: 1,000+ AI avatars, 400+ voices, 140+ languages, covering every video use case without switching tools. Founded in 2020 with over 1,000,000 videos generated and 17,000+ active users. This isn't a wrapper around a single API — it's a purpose-built video production platform.
