+# UniTemp: Unlocking Video Generation in Any Temporal Order via Bidirectional Distillation
+
+UniTemp is a few-step video diffusion model distilled from [Wan2.1](https://github.com/Wan-Video/Wan2.1) that generates videos in any temporal order (forward, backward, or in-between) with a single set of weights.

+
+## Introduction
+Existing autoregressive video diffusion models are typically restricted to forward temporal generation. UniTemp bridges this gap by supporting generation in arbitrary temporal directions. It introduces **blockwise anchor latents** to address inter-block discontinuities during backward generation and utilizes a **bidirectional distillation framework** for efficient training.
+
+## Usage
+
+Please refer to the [official repository](https://github.com/lzhangbj/UniTemp) for environment setup and model checkpoint preparation. The model supports three inference modes:
+
+### Forward Generation (past -> future)
+```bash
+bash scripts/inference_forward.sh
+```
+
+### Backward Generation (future -> past)
+```bash
+bash scripts/inference_backward.sh
+```
+
+### In-between Generation
+```bash
+# head clip + tail clip, then interpolate the transition
+bash scripts/inference_inbetween.sh
+```
