The model supports both multi-scale rendering and autoregressive generation. With multi-scale rendering, you can generate a low-resolution preview of 200-300 frames and then upscale to higher resolutions (with or without tiling).

The autoregressive generation feature allows you to condition new segments based on previously generated content. A ComfyUI implementation example is available here:
