Video production is a complex and time-consuming process that requires a lot of skills and resources. However, what if you could generate videos from text prompts with just a few clicks? That is the idea behind AnimateDiff, a video production technique that leverages Stable Diffusion models to create videos based on textual descriptions.
In this article, we will explain what is, how it works, and how to install and use it with AUTOMATIC1111 Stable Diffusion WebUI. We will also show some examples of videos generated and its limitations. If you are interested in learning more about this innovative technique, read on.
About AnimateDiff
AnimateDiff is a video production technique that leverages Stable Diffusion models to generate videos based on a given text prompt. Traditionally, text-to-image models generate still images based on textual descriptions. However, it expands this capability by producing videos instead of static images.
This technique simplifies the video generator process by requiring users to provide a text prompt, select a model and activate. Unlike traditional methods that generate singular images, it utilizes Stable Diffusion models to create videos that evolve over time, adding motion and dynamism to the generated content.
How Does AnimateDiff Work?
AnimateDiff operates by employing a control module that affects a Stable Diffusion model. This control module undergoes training using various brief video snippets. Its role is to guide the creation of images so that they resemble the learned video clips.
Control module in AnimateDiff is adaptable with ANY Stable Diffusion model. Presently, it’s compatible only with Stable Diffusion v1.5 models. This means the control module of, like ControlNet, can work alongside different Stable Diffusion models, but at the moment, it specifically functions with Stable Diffusion v1.5 models.
How to Install AnimateDiff for AUTOMATIC1111
To install the AnimateDiff extension for AUTOMATIC1111 Stable Diffusion WebUI, follow these steps depending on your platform:
Google Colab:
Installing AnimateDiff within the Colab Notebook is a simple process. Just go to the Extensions section and select the option to enable it.
Windows or Mac:
- Start AUTOMATIC1111 Web-UI as usual.
- Go to the Extension Page within the Web-UI interface.
- Click on the “Install from URL” tab.
- In the field labeled “URL for extension’s git repository,” enter the following URL:
https://github.com/continue-revolution/sd-webui-animatediff
- Wait for a confirmation message indicating that the installation has been completed successfully.
- Restart AUTOMATIC1111 to ensure that the AnimateDiff extension is properly integrated.
How Generate a video with AnimateDiff
It is a tool that allows you to animate your personalized text-to-image diffusion models without specific tuning. Follow this step to use:
Step 1: Select a Stable Diffusion Model
Select the CyberRealistic v3.3 model and download it. Place the downloaded model in the directory stable-diffusion-webui > models > Stable-Diffusion. In the Stable Diffusion checkpoint dropdown menu, pick cyberrealistic_v33.safetensors.
Step 2: Enter txt2img Settings
- Prompt: long highlighted hair, cybergirl, futuristic silver armor suit, confident stance, high-resolution, living room, smiling, head tilted.
- Negative Prompt: CyberRealistic_Negative-neg (requires installation)
- Steps: 20
- Sampler: DPM++ 2M Karras
- CFG scale: 10
- Seed: -1
- Size: 512×512
- Adjust the batch count for generating multiple videos simultaneously.
Step 3: Enter AnimateDiff Settings
- Scroll down to the section on the txt2img page.
- Motion Module: mm_sd_v15_v2.ckpt
- Enable AnimateDiff: Yes
- Number of frames: 32 (This determines the video length)
- FPS: 8 (Frames per second, so 32 frames / 8 fps = 4 seconds for the video length)
- Leave the remaining settings as default.
- Choose MP4 in the Save options if you prefer to save the video in MP4 format.
Step 4: Generate the Video
Click on the “Generate” button to create the video. The output should resemble the intended video based on the provided settings.
Limitation of AnimateDiff
Video generated by AnimateDiff relies on learned motion patterns from its training data, resulting in a generic motion commonly observed. It doesn’t create a video following a precise sequence of motions described in the prompt. Quality of motion heavily depends on the training data.
It cannot animate unique graphics that were not part of its training data. When selecting content to animate, consider that not all subjects and styles yield the same results. Some subjects might produce better animations due to their presence in the training data, while others might not animate as effectively due to their limited representation.
Frequently Asked Questions
Which models are supported by AnimateDiff?
Currently, it supports Stable Diffusion v1.5 models. Users can also integrate ControlNet with various Stable Diffusion models.
How do I use AnimateDiff?
To use AnimateDiff, select a Stable Diffusion model, provide a text prompt describing the desired video content, configure txt2img and settings, then generate the video.
Is AnimateDiff suitable for all types of content?
It performs best with subjects and styles present in its training data. Choosing prompts aligned with the training data increases the likelihood of generating better-quality animations.
Conclusion
In conclusion, AnimateDiff is a powerful and innovative technique that enables users to generate videos from text prompts using Stable Diffusion models. It simplifies the video production process by requiring only a text description, a model selection, and a few settings.
It is compatible with any Stable Diffusion model, but currently only works with Stable Diffusion v1.5 models. It can be installed as an extension for AUTOMATIC1111 Stable Diffusion WebUI, which provides a user-friendly interface for video generation.
