-<em>Our method Text2Video-Zero enables zero-shot video generation using (i) a textual prompt (see rows 1, 2),  (ii) a prompt combined with guidance from poses or edges (see lower right), and  (iii)  Video Instruct-Pix2Pix, i.e., instruction-guided video editing (see lower left).
-    Results are temporally consistent and follow closely the guidance and textual prompts.</em>

-We provide already prepared model files derived from CIVITAI for `anime` (keyword `1girl`), `arcane style` (keyword `arcane style`) `avatar` (keyword `avatar style`) and `gta-5 style`  (keyword `gtav style`).
---->
-<!---
-To this end, download the model files from [google drive](https://drive.google.com/drive/folders/1uwXNjJ-4Ws6pqyjrIWyVPWu_u4aJrqt8?usp=share_link) and extract them into `models/control_db/`.
---->
-## Inference API
-To run inferences create an instance of `Model` class
-```python
-import torch
-from model import Model
-model = Model(device = "cuda", dtype = torch.float16)
-```
----
-### Text-To-Video
-To directly call our text-to-video generator, run this python command which stores the result in `tmp/text2video/A_horse_galloping_on_a_street.mp4` :
-```python
-prompt = "A horse galloping on a street"
-params = {"t0": 44, "t1": 47 , "motion_field_strength_x" : 12, "motion_field_strength_y" : 12, "video_length": 8}
-out_path, fps = f"./text2video_{prompt.replace(' ','_')}.mp4", 4
-model.process_text2video(prompt, fps = fps, path = out_path, **params)
-```
-To use a different stable diffusion base model run this python command:
-```python
-from hf_utils import get_model_list
-model_list = get_model_list()
-for idx, name in enumerate(model_list):
-  print(idx, name)
-idx = int(input("Select the model by the listed number: ")) # select the model of your choice
-model.process_text2video(prompt, model_name = model_list[idx], fps = fps, path = out_path, **params)
-```
-#### Hyperparameters (Optional)
-You can define the following hyperparameters:
-* **Motion field strength**:   `motion_field_strength_x` = $\delta_x$  and `motion_field_strength_y` = $\delta_x$ (see our paper, Sect. 3.3.1). Default: `motion_field_strength_x=motion_field_strength_y= 12`.
-* $T$ and $T'$ (see our paper, Sect. 3.3.1). Define values `t0` and `t1` in the range `{0,...,50}`. Default: `t0=44`, `t1=47` (DDIM steps). Corresponds to timesteps `881` and `941`, respectively.
-* **Video length**: Define the number of frames `video_length` to be generated. Default: `video_length=8`.
----
-### Text-To-Video with Pose Control
-To directly call our text-to-video generator with pose control, run this python command:
-```python
-prompt = 'an astronaut dancing in outer space'
-motion_path = '__assets__/poses_skeleton_gifs/dance1_corr.mp4'
-out_path = f"./text2video_pose_guidance_{prompt.replace(' ','_')}.gif"
-model.process_controlnet_pose(motion_path, prompt=prompt, save_path=out_path)
-```
----
-### Text-To-Video with Edge Control
-To directly call our text-to-video generator with edge control, run this python command:
-```python
-prompt = 'oil painting of a deer, a high-quality, detailed, and professional photo'
-video_path = '__assets__/canny_videos_mp4/deer.mp4'
-out_path = f'./text2video_edge_guidance_{prompt}.mp4'
-model.process_controlnet_canny(video_path, prompt=prompt, save_path=out_path)
-```
-#### Hyperparameters
-You can define the following hyperparameters for Canny edge detection:
-* **low threshold**. Define value `low_threshold` in the range $(0, 255)$. Default: `low_threshold=100`.
-* **high threshold**. Define value `high_threshold` in the range $(0, 255)$. Default: `high_threshold=200`. Make sure that `high_threshold` > `low_threshold`.
-You can give hyperparameters as arguments to `model.process_controlnet_canny`
----
-### Text-To-Video with Edge Guidance and Dreambooth specialization
-Load a dreambooth model then proceed as described in `Text-To-Video with Edge Guidance`
-```python
-prompt = 'your prompt'
-video_path = 'path/to/your/video'
-dreambooth_model_path = 'path/to/your/dreambooth/model'
-out_path = f'./text2video_edge_db_{prompt}.gif'
-model.process_controlnet_canny_db(dreambooth_model_path, video_path, prompt=prompt, save_path=out_path)
-```
-The value `video_path` can be the path to a `mp4` file. To use one of the example videos provided, set `video_path="woman1"`, `video_path="woman2"`, `video_path="woman3"`, or `video_path="man1"`.
-The value `dreambooth_model_path` can either be a link to a diffuser model file, or the name of one of the dreambooth models provided. To this end, set `dreambooth_model_path = "Anime DB"`, `dreambooth_model_path = "Avatar DB"`, `dreambooth_model_path = "GTA-5 DB"`, or `dreambooth_model_path = "Arcane DB"`.  The corresponding keywords are: `1girl` (for `Anime DB`), `arcane style` (for `Arcane DB`) `avatar style` (for `Avatar DB`) and `gtav style`  (for `GTA-5 DB`).
-To load custom Dreambooth models, [transfer](https://github.com/lllyasviel/ControlNet/discussions/12) control to the custom model and  [convert](https://github.com/huggingface/diffusers/blob/main/scripts/convert_original_stable_diffusion_to_diffusers.py) it to diffuser format. Then, the value of `dreambooth_model_path` must link to the folder containing the diffuser file. Dreambooth models can be obtained, for instance, from [CIVITAI](https://civitai.com).
----
-### Video Instruct-Pix2Pix
-To perform pix2pix video editing, run this python command:
-```python
-prompt = 'make it Van Gogh Starry Night'
-video_path = '__assets__/pix2pix video/camel.mp4'
-out_path = f'./video_instruct_pix2pix_{prompt}.mp4'
-model.process_pix2pix(video_path, prompt=prompt, save_path=out_path)
-```
----
-### Low Memory Inference
-Each of the above introduced interface can be run in a low memory setup. In the minimal setup, a GPU with **12 GB VRAM** is sufficient.
-To reduce the memory usage, add `chunk_size=k` as additional parameter when calling one of the above defined inference APIs. The integer value `k` must be in the range `{2,...,video_length}`. It defines the number of frames that are processed at once (without any loss in quality). The lower the value the less memory is needed.
-When using the gradio app, set `chunk_size` in the `Advanced options`.
-We plan to release soon a new version that further reduces the memory usage.
 ---
-### Ablation Study
-To replicate the ablation study, add additional parameters when calling the above defined inference APIs.
-*  To deactivate `cross-frame attention`: Add `use_cf_attn=False` to the parameter list.
-* To deactivate enriching latent codes with `motion dynamics`: Add `use_motion_field=False` to the parameter list.
-Note: Adding `smooth_bg=True` activates background smoothing. However, our  code does not include the salient object detector necessary to run that code.
 ---
-## Inference using Gradio
-From the project root folder, run this shell command:
-```shell
-python app.py
-```
-Then access the app [locally](http://127.0.0.1:7860) with a browser.
-To access the app remotely, run this shell command:
-```shell
-python app.py --public_access
-```
-For security information about public access we refer to the documentation of [gradio](https://gradio.app/sharing-your-app/#security-and-file-access).
