Summary
PE-Field 4D revisits positional encoding in video diffusion transformers, showing it provides spatial bias for better geometry-aware control under viewpoint and camera motion changes. Encoding reference tokens by their projected positions improves scene geometry handling in video generation.

What happened
Diffusion Transformers have recently achieved strong performance in video generation, yet controlling scene geometry under viewpoint changes and camera motion remains challenging. In this work, we revisit the role of positional encoding in video diffusion transformers and show that it provides a useful spatial...
Why it matters
Controlling scene geometry in generated videos is a key challenge for realistic video synthesis, especially with camera motion. This approach offers a method to improve spatial consistency and control in AI-generated videos.
