Code Sample
Comparison with Other Models
vs Ray 1: Ray 2 offers 10x higher compute power, enabling production-quality videos with more coherent motion and enhanced realism, while Ray 1 mainly served as a proof-of-concept with lower fidelity.
vs Stable Diffusion: Ray 2 provides superior natural motion and cinematic camera control, unlike basic video diffusion which may lack temporal coherence and smooth tracking shots.
vs Midjourney Video: Unlike Midjourney which focuses on image generation with limited video support, Ray2 is specialized for video from text inputs with detailed narrative and motion handling.
vs Flux 1.1: Ray2 exceeds Flux 1.1 in resolution support, motion smoothness, and production readiness, making it more suitable for professional content creation.
