Most "AI video generator" lists are really clip-generator lists, as most tools cap out around 60 seconds, but six names stand out for true 10+ minute output. LongStories.ai is built specifically for long-form narrative video, supporting up to 15 minutes per video with consistent characters across scenes; its Pro plan supports up to 10 minutes per video at $59/mo, and Creator Max extends to 15 minutes. MagicLight advertises longer maximums of up to 50 minutes on a similar story-engine model, with a list price of ~$12/mo. HeyGen and Synthesia can produce long-form video but are built around talking avatars rather than animated narratives; HeyGen supports up to 60 minutes at the Business tier and $29/mo for Creator (up to 30 min), while Synthesia offers ~10–30 min per month allotment at $29/mo for Starter. Pictory and InVideo AI are best for turning existing long-form content into video rather than generating original long scenes. Clip models like Veo, Kling, Runway, and Sora remain limited to short segments of seconds to ~1–2 minutes per clip and are better used as B-roll. For a full narrative video past 10 minutes with consistent characters, LongStories.ai is the strongest fit.
