Runway Gen-3 vs Synthesia
Runway's Gen-3 Alpha generates short video clips — up to about 10 seconds — from text prompts or a starting image, with noticeably more consistent motion than earlier video models. The web interface is straightforward: type a prompt or upload an image, choose a duration, and generate. Output runs on a credit system, so longer or higher-quality generations consume credits quickly, and the 10-second clip limit means longer sequences have to be stitched together from multiple generations. For teams, Runway also offers a Team plan (2–9 seats) with shared workspaces and pooled credits — useful for studios collaborating on the same projects.
Synthesia is built around enterprise video production: a library of 230+ professional-looking stock avatars, support for over 140 languages and accents, and templates designed for corporate training, onboarding, and internal communications. There's no permanent free tier, but a free trial lets you generate a short video to evaluate quality before subscribing; paid plans start around $29/mo for individuals, with enterprise pricing for teams that need custom avatars (created via a studio recording session), brand kits, and collaboration features. The avatar quality and language coverage are strong, but per-minute video limits on lower tiers mean longer training modules can require a higher-tier plan.
