Leak claims ByteDance’s Seedance 3.0 can generate 10+ minute AI film

Rumors about Seedance 3.0 have surfaced on Chinese X, and they are mind-blowing if true:

According to leaks from Dr. Liu Zheng (@mokoocn), ByteDance’s video generation AI has entered its final “closed-door sprint” and is aiming to end the era of short clips forever. If these specs are real, we are looking at the “feature film era” of AI:

🎥 Infinite Continuous Generation
The 15-second limit is dead. Seedance 3.0 reportedly supports seamless single-take generations of 10+ minutes (with internal tests reaching 18 minutes without collapse). It uses a “narrative memory chain” to remember plot points, character personalities, and settings, effectively allowing it to “direct” multi-act stories with suspense and twists like a human.

🗣️ Native Multi-Language & Emotional Dubbing
No more post-production lip-syncing. The model allegedly handles end-to-end video and audio generation simultaneously. It can output perfect lip-sync in Chinese, English, Japanese, and Korean, while dynamically adjusting breathing, crying, or laughing to match the character’s emotional state.

🎬 Hollywood-Grade Director Control
Forget simple prompts; this supports “storyboard script input” and real-time director commands (e.g., “Shot 1: Wide-angle dolly push…”). It reportedly understands cinematic language instantly and includes industry-standard color grading presets like IMAX and Netflix-style looks.

📉 The “Nuclear Bomb” Cost Reduction
Perhaps the most disruptive claim: The compute cost for 1 minute of cinematic video has supposedly dropped to 1/8th of Seedance 2.0. This would make high-end video production cost pennies compared to traditional crews, described as a “dimension-reduction strike” against the ad and short-drama industries.

If this ships, the barrier to entry for creating full-length movies just evaporated.
