## Inference

**Time-to-Move (TTM)** is a plug-and-play technique that can be integrated into any image-to-video diffusion model. 
We provide implementations for **Wan 2.2**, **CogVideoX**, and **Stable Video Diffusion (SVD)**.
As expected, the stronger the base model, the better the resulting videos. 
Adapting TTM to new models and pipelines is straightforward and can typically be done in just a few hours.
We **recommend using Wan**, which generally produces higher‑quality results and adheres more faithfully to user‑provided motion signals.


For each model, you can use the [included examples](./examples/) or create your own as described in
[Generate Your Own Cut-and-Drag Examples](#generate-your-own-cut-and-drag-examples).

### Dual Clock Denoising
TTM depends on two hyperparameters that start different regions at different noise depths. In practice, we do not pass `tweak` and `tstrong` as raw timesteps. Instead we pass `tweak-index` and `tstrong-index`, which indicate the iteration at which each denoising phase begins out of the total `num_inference_steps` (50 for all models).
Constraints: `0 ≤ tweak-index ≤ tstrong-index ≤ num_inference_steps`.

* **tweak-index** — when the denoising process  **outside the mask** begins.
  - Too low: scene deformations, object duplication, or unintended camera motion.
  - Too high: regions outside the mask look static (e.g., non-moving backgrounds).
* **tstrong-index** — when the denoising process **within the mask** begins. In our experience, this depends on mask size and mask quality.
   - Too low: object may drift from the intended path.
   - Too high: object may look rigid or over-constrained.


### Wan
To set up the environment for running Wan 2.2, follow the installation instructions in the official [Wan 2.2 repository](https://github.com/Wan-Video/Wan2.2). Our implementation builds on the [🤗 Diffusers Wan I2V pipeline](https://github.com/huggingface/diffusers/blob/345864eb852b528fd1f4b6ad087fa06e0470006b/src/diffusers/pipelines/wan/pipeline_wan_i2v.py) 
adapted for TTM using the I2V 14B backbone.

#### Run inference (using the included Wan examples):
```bash
python run_wan.py \
  --input-path "./examples/cutdrag_wan_Monkey" \
  --output-path "./outputs/wan_monkey.mp4" \
  --tweak-index 3 \
  --tstrong-index 7
```

#### Good starting points:
* Cut-and-Drag: tweak-index=3, tstrong-index=7
* Camera control: tweak-index=2, tstrong-index=5

  <summary><big><strong>CogVideoX</strong></big></summary><br>

  To set up the environment for running CogVideoX, follow the installation instructions in the official [CogVideoX repository](https://github.com/zai-org/CogVideo).
  Our implementation builds on the [🤗 Diffusers CogVideoX I2V pipeline](https://github.com/huggingface/diffusers/blob/main/src/diffusers/pipelines/cogvideo/pipeline_cogvideox_image2video.py), which we adapt for Time-to-Move (TTM) using the CogVideoX-I2V 5B backbone.


#### Run inference (on the included 49-frame CogVideoX example):
```bash
python run_cog.py \
  --input-path "./examples/cutdrag_cog_Monkey" \
  --output-path "./outputs/cog_monkey.mp4" \
  --tweak-index 4 \
  --tstrong-index 9
```

To set up the environment for running SVD, follow the installation instructions in the official [SVD repository](https://github.com/Stability-AI/generative-models).  
Our implementation builds on the [🤗 Diffusers SVD I2V pipeline](https://github.com/huggingface/diffusers/blob/8abc7aeb715c0149ee0a9982b2d608ce97f55215/src/diffusers/pipelines/stable_video_diffusion/pipeline_stable_video_diffusion.py#L147
), which we adapt for Time-to-Move (TTM).

#### To run inference (on the included 21-frame SVD example):
```bash
python run_svd.py \
  --input-path "./examples/cutdrag_svd_Fish" \
  --output-path "./outputs/svd_fish.mp4" \
  --tweak-index 16 \
  --tstrong-index 21
```

## Generate Your Own Cut-and-Drag Examples
We provide an easy-to-use GUI for creating cut-and-drag examples that can later be used for video generation in **Time-to-Move**. We recommend reading the [GUI guide](GUIs/README.md) before using it.

<p align="center">
  <img src="assets/gui.png" alt="Cut-and-Drag GUI Example" width="400">
</p>

To get started quickly, create a new environment and run:
```bash
pip install PySide6 opencv-python numpy imageio imageio-ffmpeg
python GUIs/cut_and_drag.py
```
