Multi Resolution Video Generation With Native 480p 720p Support

via “multi-scale pipeline with progressive resolution generation”

Official repository for LTX-Video

Unique: Implements progressive multi-scale generation with conditioning between passes, enabling 4K+ video generation through iterative upscaling and refinement rather than single-pass high-resolution diffusion, reducing memory requirements by ~75% vs. direct high-resolution generation

vs others: Multi-scale pipeline enables 4K generation on 24GB GPUs, whereas single-pass approaches require 48GB+; progressive refinement also improves detail quality compared to naive upscaling
