The benefits of 720p are obvious: detail. Fine textures (fabric weaves, skin pores, grass blades) are preserved. The drawback is VRAM consumption. Generating 720p video requires significantly more memory than 480p or 540p variants.
The model architecture and technical details are documented in the Wan2.1 Technical Report (and related Hugging Face pages) by the Key Technical Specifications Architecture : Built on the Flow Matching framework within a Diffusion Transformer (DiT) Model Size
Specifically optimized for 720p high-definition output.
