After weeks of iteration, I built a system that generates UGC-style product videos of ANY duration with ZERO hallucinations.
Here's the magic:
- Upload your product photo
- Pick a persona (from database, upload custom, or let AI create one)
- Set your duration — 5 seconds or 5 minutes, doesn't matter
- Hit go
The system handles EVERYTHING:
✅ Consistent persona across the entire video (no face morphing!)
✅ Product stays intact (no logo changes, no weird mutations)
✅ Seamless transitions between segments (hard cuts that feel like one continuous shot)
✅ Auto-generated captions with karaoke-style highlighting
✅ Smart music selection based on product type
✅ Full control over every parameter
The catch? It takes time. A 40-second video = ~15 minutes of processing. But it's fully hands-off — you set it and forget it.
Slowly but surely, frame by frame, segment by segment... it just works.
Happy to share more details if anyone's interested !
