Bach 1.0 Pro

Bach 1.0 Pro is an industrial-grade AI video generation engine developed by Video Rebirth, a Singapore-based company founded by former Tencent distinguished scientist Dr. Wei Liu. Launched in May 2026, the model is designed to bridge the gap between individual clip generation and professional film production by focusing on directorial intent. It specializes in multi-shot storytelling, maintaining character identity, lighting continuity, and cinematic camera language across sequences up to 30 seconds in length without requiring manual stitching.

The model is built on two proprietary architectures: the Dual Diffusion Transformer (DDiT) and Physics-Native Attention (PNA). These frameworks enable the engine to interpret professional cinematographic instructions—such as specific lens types, camera movements, and emotional transitions—with high physical accuracy. The system produces native 1080p output at 30 frames per second and features an integrated audio engine that generates synchronized sound effects, voiceovers, and background music in a single pass.

Bach 1.0 Pro provides five primary creation modes: Montage for coherent multi-shot films, Text to Video, Image to Video, Element to Video (generating motion from specific visual components), and an integrated image-to-video workflow. For professional results, users can utilize reference images for characters or locations to anchor visual identity. Providing detailed shot-by-shot descriptions in natural language allows the engine to execute complex sequences like whip pans or subtle emotional shifts while keeping the character's appearance stable across cuts.
