How to Use Stable Video Diffusion: Guide and Alternative

Stable Video Diffusion (SVD) by Stability AI

Stable Video Diffusion (SVD) is Stability AI's sole official text-to-video model, created to generate realistic, animated video from text input. It is an extraordinary breakthrough among generative video capabilities, equipping creators with an incredibly potent means to weave imagination into reality with little effort.

• Key specs

SVD can generate videos for 2 - 5 seconds at flexible frame rates ranging from 3 to 30 frames per second. The resolution can be as high as 1024 pixels for high-definition visuals for online engagement. A short video clip takes an average of 2 minutes to create, making it an effective means for quick content creation.

• Best suited for

This model is particularly suitable for building rapid concept previews that bring concepts to life. It is also ideal for use with AI storytelling, where users can create animated stories from basic text. Moreover, Stable Diffusion for video generation is suitable for creating explainer videos and other short-form content pieces that are improved by having compelling visuals.

Core concepts and architecture of Stable Video Diffusion

Stable Video Diffusion (SVD) expands on strong foundations in generative AI with images, taking them into the dynamic domain of video. Fundamentally, Stable Video Diffusion uses denoising diffusion models to create coherent, aesthetically compelling motion out of text input, an achievement that relies on both temporal and spatial comprehension.

Basics of SVD models

Stable Video Diffusion (SVD) is a specially adapted latent diffusion model for high-resolution text-to-video and image-to-video generation. Unlike image-based models, however, SVD makes the fundamental concept of denoising diffusion applicable to video by incorporating temporal layers into the model architecture. This allows the model to output high-quality frames as separate units and provide coherence and smooth motion over a collection of frames.

Training of Stable Video Diffusion models consists of three main stages:

• Text-to-image pretraining: First, the model is pretrained from large-scale image datasets to comprehend static visual content.
• Video pretraining: Then, temporal elements are introduced, and the model is exposed to a pre-curated set of video data so that it learns frame-to-frame consistency.
• Fine-tuning of high-quality videos: Next, the model is fine-tuned using smaller, high-quality video datasets to boost the generated videos' realism and stability.

How SVD works

Stable Video Diffusion uses latent diffusion in a U‑Net framework, initially popularized in 2D image synthesis. The U‑Net optimizes data compression and reconstruction in latent space with minimal computational burden, ensuring that critical visual information is retained. This ensures that the output video has coherent, frame-to-frame logic and fluidity, even when rendered from a static input description.

Step-by-step workflow for stable diffusion video generation

1
1. Download and set up the models

Start by accessing links for the required SVD models. There are two versions available:

SVD (SafeTensor): This version generates 14-frame videos. Click the download link and save the model file into the folder within your ComfyUI directory.

SVD-XT: This enhanced version generates smoother videos with 25 frames. It follows a similar download and setup process but results in more fluid animation.

2
1. Set up ComfyUI and load workflows

Install and launch ComfyUI, a visual node-based interface for AI workflows. Once open, you can import pre-built workflows (in JSON format) for video generation:

Go to the example section from the given link (https://comfyanonymous.github.io/ComfyUI_examples/video/). Right-click on the workflow JSON format and choose "Save link as…", and store it locally.

• In ComfyUI, drag and drop the JSON file onto the canvas to load the full video generation setup instantly.

1. Configure SVD parameters

Prior to rendering out your video, adjust the critical parameters in ComfyUI to achieve your desired effects. These parameters have a direct effect on the appearance, smoothness, and motion dynamics of your video:

• Frame count: Determine how long your animation will last by choosing the total frames. The longer the animation, the more frames it will have.
• Frame rate (FPS): Select the frame rate to manage playback smoothness. More frames provide greater motion smoothness, particularly optimal for storytelling and cinematic output.
• Motion bucket ID: This is control over motion intensity from frame to frame. Lower values provide subtle movements, with larger values creating more lively, rapid motion.
• Sampler and scheduler: Choose the diffusion algorithm and timing schedule that dictate how frames are produced. Some will provide sharper details, whilst others will prioritize speed or stylized output.
• Seed: Input a seed value to recreate the same result every time, or randomize it to try out different creative variations from the same prompt.

1. Generate videos from a text prompt (text-to-image-to-video)

To start from scratch, you can first generate a base image using a descriptive text prompt. In ComfyUI, load a text-to-image-to-video workflow and enter your prompt—this will serve as the foundation for your video.

Example prompt: photograph burning house on fire, smoke, ashes, embers

• Use a high-quality checkpoint (e.g., SDXL or Realistic Vision) in the text-to-image node.
• Adjust CFG (Classifier-Free Guidance) and sampling steps to balance detail and creativity.
• Once the image is generated, inspect it to ensure it aligns with your vision.

This image will serve as the input for the next stage—Stable Video Diffusion, where motion is added to bring the still scene to life.
