# Infinite Zoom extension for [Stable Diffusion WebUI](https://github.com/AUTOMATIC1111/stable-diffusion-webui/).
This is an extension for the AUTOMATIC1111's (and Vladmandic´s) webui that allows users to create infinite zoom effect videos using stable diffusion outpainting method.
## How to install?
Click to expand
1. Open [Stable Diffusion WebUI](https://github.com/AUTOMATIC1111/stable-diffusion-webui/).
2. Go to the `Extensions tab` > `Install from URL`.
3. Enter `https://github.com/v8hid/infinite-zoom-automatic1111-webui.git` for the URL and leave the second field empty and wait for it to be installed.
> 
4. Go to the Installed tab and press Apply, wait for installation, and restart.
> 
5. Wait for the Stable Diffusion WebUI to restart and now you can try the Infinite Zoom extension.
## How to use?
Click to expand
1. Click on the Infinite Zoom tab 
2. Modify the parameters as you wish and click Generate video, the video will appear as soon as it generates

## Effective Friendly Tips for Optimal Outcomes
Click to expand
* You're only as good as your model, so level up with an Inpainting model for killer results.
* Heads up: Setting Mask Blur parameter above 0 will give you results that look like they've been hit by the ugly stick.
* Just between us - don't forget to uncheck Apply color correction to img2img results to match original colors in the Stable Diffusion tab of the WebUI settings. You don't want your results looking like a bad Instagram filter.

## How it works?
Click to expand
To start, let's break down the workflow of the extension into three main steps:
- **Step 1: Choose an image to start with**
The program either generates an initial image using the first prompt you provide or you can upload your own image in the `custom initial image` field. This initial image will be the basis for the outpainting process.
- **Step 2: Generate outpaint steps**
Once you have your initial image, the program will start generating outpaint steps. The number of outpaint steps is determined by the `Total Outpaint Steps` input. In each outpaint step, the program makes the initial image smaller in the center of the canvas and generates a new image in the empty space that is created. This process is repeated for each outpaint step until the desired number is reached.
- **Step 3: Create a gradual zoom effect**
After all outpaint steps have been generated, the program creates an interpolation between each outpaint step to create a gradual zoom effect. The number of frames created between each outpaint step is determined by the `Zoom Speed` parameter and the `Frames per second` parameter.
Number of frames for each outpaint step = `Zoom Speed` $\times$ `Frames per second`
Length of each outpaint step in second = `Number of frames` $\div$ `Frames per second`
