# What is latent blending?
|
|
|
|
Latent blending allows you to generate smooth video transitions between two prompts. It is based on [stable diffusion 2.0](https://stability.ai/blog/stable-diffusion-v2-release) and remixes the latent reprensetation using spherical linear interpolations. This results in imperceptible transitions, where one image slowly turns into another one.

|
# Example 1: simple transition
|
|
(mp4), code
|
|
|
|
# Example 2: inpainting transition
|
|
(mp4), code
|
|
|
|
# Example 3: concatenated transition
|
|
(mp4), code

# Installation
|
|
#### Packages
|
|
```commandline
|
|
pip install -r requirements.txt
|
|
```
|
|
#### Download Models from Huggingface
|
|
[Download the Stable Diffusion 2.0 Standard Model](https://huggingface.co/stabilityai/stable-diffusion-2)
|
|
|
|
[Download the Stable Diffusion 2.0 Inpainting Model (optional)](https://huggingface.co/stabilityai/stable-diffusion-2-inpainting)
|
|
|
|
#### Install [Xformers](https://github.com/facebookresearch/xformers)
|
|
With xformers, stable diffusion 2 will run much faster. The recommended way of installation is via the supplied binaries (Linux).
|
|
|
|
```commandline
|
|
conda install xformers -c xformers/label/dev
|
|
```
|
|
|
|
Alternatively, you can build it from source:
|
|
```commandline
|
|
# (Optional) Makes the build much faster
|
|
pip install ninja
|
|
# Set TORCH_CUDA_ARCH_LIST if running and building on different GPU types
|
|
pip install -v -U git+https://github.com/facebookresearch/xformers.git@main#egg=xformers
|
|
# (this can take dozens of minutes)
|
|
```
|
|
|
|
# How does it work

what makes a transition a good transition?
|
|
* absence of movement
|
|
* every frame looks like a credible photo
