Follow-Your-Canvas is a video upscaling technology based on a diffusion model that can generate high-resolution video content. This technology addresses GPU memory limitations through distributed processing and spatial window merging while maintaining both spatial and temporal consistency in the video. It excels in large-scale video upscaling, significantly enhancing video resolution (e.g., from 512 x 512 to 1152 x 2048) while delivering high-quality and visually pleasing results.
