+
3
+ ## 1. Overall Steps
4
+
5
+ - Preparation: Be aware of the task type ([single task](#32-single-task) or [multi-task composition](#33-composition-task)) of your creative idea, and prepare all the required materials (images, videos, prompt, etc.)
6
+ - Preprocessing: Select the appropriate preprocessing method based task name, then preprocess your materials to meet the model's input requirements.
7
+ - Inference: Based on the preprocessed materials, perform VACE inference to obtain results.
8
+
9
+ ## 2. Preparations
10
+
11
+ ### 2.1 Task Definition
12
+
13
+ VACE, as a unified video generation solution, simultaneously supports Video Generation, Video Editing, and complex composition task. Specifically:
14
+
15
+ - Video Generation: No video input. Injecting concepts into the model through semantic understanding based on text and reference materials, including **T2V** (Text-to-Video Generation) and **R2V** (Reference-to-Video Generation) tasks.
16
+ - Video Editing: With video input. Modifying input video at the pixel level globally or locally,including **V2V** (Video-to-Video Editing) and **MV2V** (Masked Video-to-Video Editing).
17
+ - Composition Task: Compose two or more single task above into a complex composition task, such as **Reference Anything** (Face R2V + Object R2V), **Move Anything**(Frame R2V + Layout V2V), **Animate Anything**(R2V + Pose V2V), **Swap Anything**(R2V + Inpainting MV2V), and **Expand Anything**(Object R2V + Frame R2V + Outpainting MV2V), etc.
18
+
19
+ Single tasks and compositional tasks are illustrated in the diagram below:
20
+
21
+ ![vace_task](https://raw.githubusercontent.com/ali-vilab/VACE/refs/heads/main/assets/materials/tasks.png)
22
+
23
+
24
+ ### 2.2 Limitations
25
+
26
+ - Super high resolution video will be resized to proper spatial size.
27
+ - Super long video will be trimmed or uniformly sampled into around 5 seconds.
28
+ - For users who are demanding of long video generation, we recommend to generate 5s video clips one by one, while using `firstclip` video extension task to keep the temporal consistency.
29
+
30
+ ## 3. Preprocessing
31
+ ### 3.1 VACE-Recognizable Inputs
32
+
33
+ User-collected materials needs to be preprocessed into VACE-recognizable inputs, including **`src_video`**, **`src_mask`**, **`src_ref_images`**, and **`prompt`**.
34
+ Specific descriptions are as follows:
35
+
36
+ - `src_video`: The video to be edited for input into the model, such as condition videos (Depth, Pose, etc.) or in/outpainting input video. **Gray areas**(values equal to 127) represent missing video part. In first-frame R2V task, the first frame are reference frame while subsequent frames are left gray. The missing parts of in/outpainting `src_video` are also set gray.
37
+ - `src_mask`: A 3D mask in the same shape of `src_video`. **White areas** represent the parts to be generated, while **black areas** represent the parts to be retained.
38
+ - `src_ref_images`: Reference images of R2V. Salient object segmentation can be performed to keep the background white.
39
+ - `prompt`: A text describing the content of the output video. Prompt expansion can be used to achieve better generation effects for LTX-Video and English user of Wan2.1. Use descriptive prompt instead of instructions.
40
+
41
+ Among them, `prompt` is required while `src_video`, `src_mask`, and `src_ref_images` are optional. For instance, MV2V task requires `src_video`, `src_mask`, and `prompt`; R2V task only requires `src_ref_images` and `prompt`.
42
+
43
+ ### 3.2 Preprocessing Tools
44
+ Both command line and Gradio demo are supported.
45
+
46
+ 1) Command Line: You can refer to the `run_vace_preproccess.sh` script and invoke it based on the different task types. An example command is as follows:
47
+ ```bash
48
+ python vace/vace_preproccess.py --task depth --video assets/videos/test.mp4
49
+ ```
50
+
51
+ 2) Gradio Interactive: Launch the graphical interface for data preprocessing and perform preprocessing on the interface. The specific command is as follows:
52
+ ```bash
53
+ python vace/gradios/preprocess_demo.py
54
+ ```
55
+
56
+ ![gr_pre_demo](https://raw.githubusercontent.com/ali-vilab/VACE/refs/heads/main/assets/materials/gr_pre_demo.jpg)
57
+
58
+
59
+ ### 3.2 Single Tasks
60
+
61
+ VACE is an all-in-one model supporting various task types. However, different preprocessing is required for these task types. The specific task types and descriptions are as follows:
62
+
63
+ | Task | Subtask | Annotator | Input modal | Params | Note |
64
+ |------------|----------------------|----------------------------|------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------|

90
+
91
+ ### 3.3 Composition Task
92
+
93
+ Moreover, VACE supports combining tasks to accomplish more complex objectives. The following examples illustrate how tasks can be combined, but these combinations are not limited to the examples provided:
94
+
95
+ | Task | Subtask | Annotator | Input modal | Params | Note |
96
+ |-------------|--------------------|----------------------------|--------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------|

102
+ | composition | more_anything | ... | ... | ... | ... |
103
+
104
+
105
+ ## 4. Model Inference
106
+
107
+ ### 4.1 Execution Methods
108
+
109
+ Both command line and Gradio demo are supported.
110
+
111
+ 1) Command Line: Refer to the `run_vace_ltx.sh` and `run_vace_wan.sh` scripts and invoke them based on the different task types. The input data needs to be preprocessed to obtain parameters such as `src_video`, `src_mask`, `src_ref_images` and `prompt`. An example command is as follows:
112
+ ```bash
113
+ python vace/vace_wan_inference.py --src_video <path-to-src-video> --src_mask <path-to-src-mask> --src_ref_images <paths-to-src-ref-images> --prompt <prompt> # wan
114
+ python vace/vace_ltx_inference.py --src_video <path-to-src-video> --src_mask <path-to-src-mask> --src_ref_images <paths-to-src-ref-images> --prompt <prompt> # ltx
115
+ ```
116
+
117
+ 2) Gradio Interactive: Launch the graphical interface for model inference and perform inference through interactions on the interface. The specific command is as follows:
118
+ ```bash
119
+ python vace/gradios/vace_wan_demo.py # wan
120
+ python vace/gradios/vace_ltx_demo.py # ltx
121
+ ```
122
+
123
+ ![gr_infer_demo](https://raw.githubusercontent.com/ali-vilab/VACE/refs/heads/main/assets/materials/gr_infer_demo.jpg)
124
+
125
+ 3) End-to-End Inference: Refer to the `run_vace_pipeline.sh` script and invoke it based on different task types and input data. This pipeline includes both preprocessing and model inference, thereby requiring only user-provided materials. However, it offers relatively less flexibility. An example command is as follows:
126
+ ```bash
127
+ python vace/vace_pipeline.py --base wan --task depth --video <path-to-video> --prompt <prompt> # wan
128
+ python vace/vace_pipeline.py --base lxt --task depth --video <path-to-video> --prompt <prompt> # ltx
129
+ ```
130
+
131
+ ### 4.2 Inference Examples
132
+
133
+ We provide test examples under different tasks, enabling users to validate according to their needs. These include **task**, **sub-tasks**, **original inputs** (ori_videos and ori_images), **model inputs** (src_video, src_mask, src_ref_images, prompt), and **model outputs**.
134
+
135
+ | task | subtask | src_video | src_mask | src_ref_images | out_video | prompt | ori_video | ori_images |
136
+ |-------------|--------------------|----------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

+ ## 5. Limitations
154
+
155
+ - VACE-LTX-Video-0.9
156
+ - The prompt significantly impacts video generation quality on LTX-Video. It must be extended in accordance with the methods described in this [system prompt](https://huggingface.co/spaces/Lightricks/LTX-Video-Playground/blob/main/assets/system_prompt_i2v.txt). We also provide input parameters for using prompt extension (--use_prompt_extend).
157
+ - This model is intended for experimental research validation within the VACE paper and may not guarantee performance in real-world scenarios. However, its inference speed is very fast, capable of creating a video in 25 seconds with 40 steps on an A100 GPU, making it suitable for preliminary data and creative validation.
158
+ - VACE-Wan2.1-1.3B-Preview
159
+ - This model mainly keeps the original Wan2.1-T2V-1.3B's video quality while supporting various tasks.
160
+ - When you encounter failure cases with specific tasks, we recommend trying again with a different seed and adjusting the prompt.
