# Vlogger
This repository is the official implementation of [Vlogger](https://arxiv.org/abs/2401.09414):

**[Vlogger: Make Your Dream A Vlog](https://arxiv.org/abs/2401.09414)**

Demo generated by our Vlogger: [Teddy Travel](https://youtu.be/ZRD1-jHbEGk)

##  Setup

### Prepare Environment
```
conda create -n vlogger python==3.10.11
conda activate vlogger
pip install -r requirements.txt
```

### Download our model and T2I base model

Our model is based on Stable diffusion v1.4, you may download [Stable Diffusion v1-4](https://huggingface.co/CompVis/stable-diffusion-v1-4) and [OpenCLIP-ViT-H-14](https://huggingface.co/laion/CLIP-ViT-H-14-laion2B-s32B-b79K) to the director of ``` pretrained ```
.
Download our model(ShowMaker) checkpoint (from [google drive](https://drive.google.com/file/d/1pAH73kz2QRfD2Dxk4lL3SrHvLAlWcPI3/view?usp=drive_link) or [hugging face](https://huggingface.co/GrayShine/Vlogger/tree/main)) and save to the directory of ```pretrained```


Now under `./pretrained`, you should be able to see the following:
```
├── pretrained
│   ├── ShowMaker.pt
│   ├── stable-diffusion-v1-4
│   ├── OpenCLIP-ViT-H-14
│   │   ├── ...

## Usage
### Inference for (T+I)2V 
Run the following command to get the (T+I)2V results:
```python
python sample_scripts/with_mask_sample.py
```
The generated video will be saved in ```results/mask_no_ref```.
### Inference for (T+I+ref)2V 
Run the following command to get the (T+I+ref)2V results:
```python
python sample_scripts/with_mask_ref_sample.py
```
The generated video will be saved in ```results/mask_ref```.
### Inference for LLM planning and make reference image
Run the following command to get script, actors and protagonist:
```python
python sample_scripts/vlog_write_script.py
```
The generated scripts will be saved in ```results/vlog/$your_story_dir/script```.

The generated reference images will be saved in ```results/vlog/$your_story_dir/img```.

!!!important: Enter your openai key in the 7th line of the file ```vlogger/planning_utils/gpt4_utils.py```
### Inference for vlog generation
Run the following command to get the vlog:
```python
python sample_scripts/vlog_read_script_sample.py
```
The generated scripts will be saved in ```results/vlog/$your_story_dir/video```.


#### More Details
You may modify ```configs/with_mask_sample.yaml``` to change the (T+I)2V conditions.

You may modify ```configs/with_mask_ref_sample.yaml``` to change the (T+I+ref)2V conditions.
For example:

```ckpt``` is used to specify a model checkpoint.

```text_prompt``` is used to describe the content of the video.

```input_path``` is used to specify the path to the image.

```ref_path``` is used to specify the path to the reference image.

```save_path``` is used to specify the path to the generated video.
