+# Step Distillation Comparison
+
+This document provides detailed quality comparisons between the original 480p I2V model and the step-distilled model.
+
+## Overview
+
+The step-distilled model reduces inference steps from 50 to 8 (or 12 steps recommended) while maintaining comparable visual quality to the original model. On RTX 4090, this achieves up to 75% reduction in end-to-end generation time, enabling a single RTX 4090 to generate videos within 75 seconds. This document showcases side-by-side comparisons to demonstrate that the distillation process does not significantly degrade output quality. For even faster generation, you can also try 4 steps, which provides faster speed with slightly reduced quality.
+
+## Comparison Results
+
+The following table shows side-by-side comparisons between the original 480p I2V model (50 steps) and the step-distilled model (8 steps). The comparisons demonstrate that the step-distilled model maintains comparable visual quality while achieving significant speedup.

+## Usage Notes
+
+- **8 or 12 steps**: Recommended default setting, provides the best balance between speed and quality
+- **4 steps**: Faster generation with slightly reduced quality, suitable for rapid prototyping
